How to post nested json using angular js in form

How to post nested json using angular js in form - java

How to POST Item Object using angularjs?
My simple java class:
#Entity
public class ProductionOrder implements Serializable {
#Enumerated(EnumType.STRING)
public Status status;
#Id
#GeneratedValue
private Long id;
#ManyToOne
#JoinColumn(name = "ITEM_ID")
private Item item;
private int plannedQty;
private Date plannedDate;
private String description;
//getters setters enum
My angular controller:
'use strict';
App.controller('PoController', ['$scope', 'PoService', function($scope, PoService) {
var vm = this;
vm.order = {id: null, status: null, item:null , plannedQty: null, plannedDate: '', description:''};
vm.orders = [];
vm.fetchAllOrders = function () {
PoService.fetchAllOrders()
.then(
function (d) {
vm.orders = d;
},
function (errResp) {
console.error('Error while fetching production orders!');
}
);
};
vm.createOrder = function (item) {
PoService.createOrder(item)
.then(
vm.fetchAllOrders,
function (errResponse) {
console.error('Error while creating production order');
}
);
};
vm.fetchAllOrders();
vm.submit = function () {
if (vm.order.id === null) {
console.log('Saving new order', vm.order);
vm.createOrder(vm.order);
} else {
console.log('Sth wrong with adding new order');
}
vm.reset();
};
vm.reset = function () {
vm.order = {id: null, status:null, item: null, plannedQty: null, plannedDate: '', description:''};
$scope.myForm.$setPristine();
};
}]);
And this is my angular service:
'use strict';
App.factory('PoService', ['$http', '$q', function ($http, $q) {
return {
fetchAllOrders: function () {
return $http.get('http://localhost:8080/api/po/all')
.then(
function (response) {
return response.data;
},
function (errResponse) {
console.error('Error while fetching production orders');
return $q.reject(errResponse);
}
);
},
createOrder: function (item) {
return $http.post('http://localhost:8080/api/po/add', item)
.then(
function (res) {
return res.data;
},
function (errRes) {
console.error('Error while adding production order');
return $q.reject(errRes);
}
);
}
};
}]);
In html I have simple form:
<div class="ui main text container", ng-controller="PoController as ctrl">
<form class="ui form" ng-submit="ctrl.submit()" name="myForm">
<h4 class="ui dividing header">Production order information</h4>
<div class="field">
<label> </label>
<div class="two fields">
<div class="field">
<input type="text" ng-model="ctrl.order.id" placeholder="Production order id">
</div>
<div class="field">
<input type="text" ng-model="ctrl.order.item" placeholder="Item id">
</div>
</div>
</div>
<h4 class="ui dividing header">Status:</h4>
<select class="ui dropdown" ng-model="ctrl.order.status">
<option value="CREATED">CREATED</option>
<option value="PLANNED">PLANNED</option>
<option value="DONE">DONE</option>
</select>
<h4 class="ui dividing header">Planning information</h4>
<div class="field">
<label> </label>
<div class="two fields">
<div class="field">
<input type="text" ng-model="ctrl.order.plannedQty" placeholder="Quantity">
</div>
<div class="field">
<input type="text" ng-model="ctrl.order.plannedDate" placeholder="Enter date RRRR-MM-DD">
</div>
</div>
</div>
</br>
<div class="field">
<label>Description</label>
<textarea ng-model="ctrl.order.descritpion"></textarea>
</div>
<div class="asbutton" id="button">
<input type="submit" value="Save" class="ui primary button" ng-disabled="myForm.$invalid">
<button class="ui button" type="button" ng-click="ctrl.reset()" ng-disabled="myForm.$pristine">
Reset
</button>
</div>
</form>
</div>
And when i type for example: 1. It means I want to create realtion with item with 1 id. In Terminal I see error:
2016-06-12 16:06:13.906 WARN 10057 --- [nio-8080-exec-3] .w.s.m.s.DefaultHandlerExceptionResolver : Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Could not read document: Can not instantiate value of type [simple type, class com.prod.domain.Item] from String value ('2'); no single-String constructor/factory method

at [Source: java.io.PushbackInputStream#2b8fb852; line: 1, column: 25] (through reference chain: com.prod.domain.ProductionOrder["item"])
How could I POST nested json similar to this:
item: {id: 6}

I passed the variable of Date type to Ajax and received it back to the controller, but the value changed

I want to receive the date through the date picker and put it in an object that stores reservation information(RentalPlacesVo).
I received the date from the reservation form and also confirmed that the controller fits the vo object well (even the datatype in rental_date was java.sql.Date)
After making the payment, I sent it to Ajax to include it with other information, and in the process of processing Ajax, I confirmed that 2022-07-23 was changed to 1992. It seems that the date has not been properly stored in the date type column of the db since the date has been changed to 1992.
I need to store data of DATE type on vo object, how can I get it?
Details of the error are as follows.
WARN : org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver - Failed to bind request element: org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'java.sql.Date'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [#org.springframework.web.bind.annotation.RequestParam java.sql.Date] for value '1992'; nested exception is java.lang.IllegalArgumentException

}

Use date related annotations on the date field.
#Temporal(TemporalType.DATE)
#DateTimeFormat(pattern = "yyyy/MM/dd")
private Date rental_date;
Best practice:
Also it is recommended to use camel case standard for pojo entity class variables like rentalDate.

Bind Form Data as JSON String/String Array to Request Params In String

I have a form which I would like to send to my controller via ajax:
<div class="row">
<label for="username" class="col-sm-2 col-form-label my-auto">Username:</label>
<div class="col-sm-10 my-auto">
<input type="text" class="form-control" id="username" name="username">
</div>
</div>
<div class="row">
<label for="password" class="col-sm-2 col-form-label my-auto">Password:</label>
<div class="col-sm-10 my-auto">
<input type="text" class="form-control" id="password" name="password">
</div>
</div>
<div class="row" id="ratingRow">
<label for="adminFoci" class="col-sm-2 col-form-label my-auto">User Rating:</label>
<div class="col-sm-auto my-auto">
<select class="selectpicker" multiple data-live-search="true" name="adminFoci" id="adminFoci" title="Choose Foci">
<c:forEach items="${foci}" var="focus">
<option name="${focus.focusName}" value="">${focus.focusName}</option>
</c:forEach>
</select>
</div>
<div class="col-sm my-auto">
<input type="text" class="form-control" id="rating" name="rating">
</div>
<div class="col-sm-auto my-auto" id="ratingButtonRow">
<div class="btn btn-info btn-sm" id="adminAddGroup">Add Rating</div>
</div>
</div>
<div class="row">
<label for="adminUserGroups" class="col-sm-2 col-form-label my-auto">User's Groups:</label>
<div class="col-sm-auto my-auto">
<select class="selectpicker" multiple data-live-search="true" id="adminUserGroups" name="groups" title="Choose Groups">
<c:forEach items="${groups}" var="group">
<option name="${group.groupName}" value="${group.groupName}">${group.groupName}</option>
</c:forEach>
</select>
</div>
</div>
<div class="row">
<label class="col-sm-2 col-form-label my-auto">User's Roles:</label>
<div class="col-sm-10 my-auto">
<select class="selectpicker" multiple data-live-search="true" id="adminUserRoles" name="roles" title="Choose Roles">
<c:forEach items="${user.roles}" var="role">
<option name="${role.name}" value="${role.name}">${role.name}</option>
</c:forEach>
</select>
</div>
</div>
I catch the form submit and serialize the form data:
$("#modalForm").submit(function(e){
e.preventDefault();
var form = $(this);
$.ajax({
type: "POST",
url: form.attr('action'),
dataType: 'json',
contentType: "application/json; charset=utf-8",
data: JSON.stringify($(this).serializeArray()),
success: function(data)
{
table.row('.selected').ajax.reload();
}
});
});
I then try to bind data of the json string array to request params in my controller:
#PostMapping(value="/AdminCreateUser", consumes = MediaType.APPLICATION_JSON_VALUE)
public void createUser(#RequestParam String username, #RequestParam String password, #RequestParam (required = false) String[] roles,
#RequestParam (required = false) String[] groups){
User user = new User(username, password);
if(roles != null){
Set<Role> roleList = roleService.findRoles(roles);
if(roleList.size() > 0){
user.setRoles(roleList);
}
}
if(groups != null){
Set<Group> groupList = groupService.findGroups(groups);
for(Group group: groupList){
group.addMember(user);
groupRepository.save(group);
}
}
userRepository.save(user);
}
However I get Resolved [org.springframework.web.bind.MissingServletRequestParameterException: Required String parameter 'username' is not present]. Does Jackson not bind matching elements of the json string array to the request parameters? If not, how do I do this? I want to save myself the effort of sending each form field as separate data

The output of serialize array will be,
[
{
"name" : "username",
"value" : "test"
},...
]
Then change the java code as,
public void createUser(#RequestBody String body){
Convert string to JSONObject and handle it as JSON. Then this will work.
If you want to handle with Request Param.
Change the content-type to multipart/form-data and post it directly to the API.

There are two way.
By using application/json
Modify your js code like this.
$("#modalForm").submit(function(e){
e.preventDefault();
var form = $(this);
//convert form data to json array of Object(name value pair)
data = []
var x = $(this).serializeArray();
$.each(x, function(i, field){
var name = field.name; var value = field.value;
data[i] = {name : value};
});
$.ajax({
type: "POST",
url: form.attr('action'),
dataType: 'json',
contentType: "application/json; charset=utf-8",
data: JSON.stringify(data),
success: function(data)
{
table.row('.selected').ajax.reload();
}
});
});
Modify your controller
public void createUser(#RequestBody CreateUserDto createUserRequest){
If you want to use request param change content-type to multipart/form-data.

If I deleted 'name' field showed the same problem with description....
Thanks for the help!

Reason for Error :
[(ngModel)]="projectData.name" , if you are using [(ngModel)] 2-way data binding it will need some initial values, but it gets undefined
1st Solution *ngIf='projectData':
<div class="container custom-container">
<form [formGroup]="updateProjectForm" (ngSubmit)="updateProject(updateProjectForm.value)" class="ui form"
style="margin-left: 3%; width: 30%;">
<h1 id="projectTitle">Update Project</h1>
<div style="margin: 0 auto;" *ngIf='projectData'> <!-- HERE -->
<div style="margin-top: 100px;">
<div class="field">
<label>Project Name</label>
<input type="text" formControlName="projectName" class="form-control" name="projectName"
[(ngModel)]="projectData.name" placeholder="Your project name"
[ngClass]="{'is-invalid' : submitted && updateProjectForm.controls.projectName.errors}" />
<div *ngIf="submitted && updateProjectForm.controls.projectName.errors" class="err_msg form-text">
<p class="err-msg">Project Name is required</p>
</div>
</div>
...
</div>
</div>
</form>
</div>
2nd Soltuion (Provide some initial value):
project: Project = {
..., // other values too
name : ''
};
3rd option, remove [(ngModel)] 2-way data binding from all:
this.project.name = projectDataFromForm.projectName;
this.project.description = projectDataFromForm.projectDescription;
this.project.expiryDate = projectDataFromForm.expiryDate;
this.project.budget = projectDataFromForm.budget;
// this.project.projectTypeId = this.idprojecttype;
this.project.projectTypeId = this.prMultiselectComponent.getSelectedItems();
this.project.skills = this.skillMultiselectComponent.getSelectedItems();
// --- Patch value will set values in your form ---
this.updateProjectForm.patchValue(this.project); // <---- HERE

I think your problem is caused by this line:
this.project.name = projectDataFromForm.projectName;
because as far as I can see, you don't instantiate your Project object.
In ngOnInit, try adding
this.project = new Project(/* include any necessary data here for the Project constructor */);

Ajax call error in Spring MVC

I have a form where I add the customer's informations. This informations are passed to #Controller by an Ajax call.
Customer.java
public class Customer {
private String name;
private String fiscalCode;
private String vat;
private String telephone;
private String webSite;
private String sector;
private String address;
//Below there are constructor and getter/setter methods
Above the form there is:
<c:set var="serverUrl" value="${pageContext.servletContext.contextPath}"/>
<script>
var serverUrl = '${serverUrl}';
</script>
Form in the jsp
<form>
<div class="form-group">
<input id="nameCustomer" class="form-control" type="text" placeholder="Name customer">
</div>
<div class="form-group">
<input id="fiscalCode" class="form-control" type="text" placeholder="Fiscal code">
</div>
<div class="form-group">
<input id="vat" class="form-control" type="number" placeholder="VAT number (if available)">
</div>
<div class="form-group">
<input id="telephone" class="form-control" type="tel" placeholder="Phone number">
</div>
<div class="form-group">
<input id="website" class="form-control" type="email" placeholder="Customer's Website (if available)">
</div>
<div class="form-group">
<input id="address" class="form-control" type="text" placeholder="Customer's Address">
</div>
<div class="form-group">
<input id="sector" class="form-control" type="text" placeholder="Sector">
</div>
<button id="createCustomer" type="button" class="btn btn-success" style="text-align: center">Save</button>
</form>
Ajax call (the link to this ajax call code is below the form)
$("#createCustomer").click(function () {
alert("createCustomer");
alert(serverUrl);
var nameCustomer = $("#nameCustomer").val();
var fiscalCode = $("#fiscalCode").val();
var vat = $("#vat").val();
var telephone = $("#telephone").val();
var website = $("#website").val();
var address = $("#address").val();
var sector = $("#sector").val();
alert(address);
$.ajax({
url: serverUrl + "/addCustomer",
dataType: 'text',
data: {name: nameCustomer,
fiscalCode: fiscalCode,
vat: vat,
telephone: telephone,
webSite: website,
address: address,
sector: sector},
success: function (data) {
$("#customerAdded").modal('show');
},
error: function (xhr, error, exception) {
$("#errorCustomer").modal('show');
}
});
});
Controller
#Controller
public class CustomerController {
#RequestMapping("addCustomer")
public void addCustomer(#ModelAttribute Customer customer){
JOptionPane.showMessageDialog(null, customer.toString());
}
Chrome gives me this error:
http://localhost:8080/ReportVisitaWeb/addCustomer?name=gdg&fiscalCode=dfgdfg&vat=&telephone=dfgg&webSite=dfggf&address=dfgddf&sector=gdg Failed to load resource: the server responded with a status of 404 (Not Found)
Why?

You are not mapping the request "addCustomer" correctly. Edit your CustomerController as below:
#Controller
public class CustomerController {
#RequestMapping("/addCustomer")
public void addCustomer(#ModelAttribute Customer customer){
JOptionPane.showMessageDialog(null, customer.toString());
}
}

Edit action returns null

I'm new to Struts2 framework and I found a problem when I try to edit an object.
The code of my modification action:
#Action(value = "modifyServer", results = {
#Result(name = "success", location = Location.MAIN_PAGE),
#Result(name = "error", location = Location.LOGIN_PAGE) })
public String modifyServer() {
em = DbConnexion.getEntityManager().createEntityManager();
String id=request.getParameter(sssid);
logger.info("id serveur = "+request.getParameter("id"));
try {
em.getTransaction().begin();
Simserver server = em.find(Simserver.class, id);
server.setSssServer(request.getParameter("sssServer"));
server.setSssIp(request.getParameter("sssIp"));
server.setSssPort(request.getParameter("sssPort"));
em.getTransaction().commit();
System.out.println("modification done !!!");
em.close();
return SUCCESS;
} catch (Exception e) {
return ERROR;
}
}
The JSP:
<form class="form-horizontal" action="modifyServer" role="form"
name="form_message" method="get">
<div id="elmsg"></div>
<div class="panel panel-info">
<div class="panel-heading expand" id="second-level">
<h6 class="panel-title">Modification du Serveur</h6>
</div>
<div class="panel-body">
<div class="form-group">

class="mandatory">*</span></label>
<div class="col-sm-10">
<input type="text" class="form-control" name="sssId"
disabled="disabled" id="sssId"
value="<s:property value="#request.curentserver.sssId" />">
</div>

</div>
<div class="form-actions text-right">
<button type="submit" value="Envoyer" class="btn btn-success"

<a role="button" href="gestionServeurList" class="btn btn-danger">Retour

</div>
When I execute my action the request.getParameter returns null.
I think the issue is in the parameter!

There are issues with code:
In Java code you are trying to print a request parameter with name as "id" instead of "sssId".
Also you are trying to use a variable called "sssid" that is no where defined in your question.
String id=request.getParameter(sssid);
logger.info("id serveur = "+request.getParameter("id"));
In JSP the sssId element is disabled, when you submit a form the disabled elements are ignored.
<input type="text" class="form-control"
name="sssId" disabled="disabled" id="sssId"
value="<s:property value="#request.curentserver.sssId" />">
So to get its value, create a hidden element in your jsp and on form submission update the hidden element with the required value using JavaScript.
<input type="hidden" name="sssId" value=""/>
In Javascript it will be like:
document.getElementById("sssId").value = 123; // Give value here
document.getElementById("myForm").submit(); // Give an Id to your form, say "myForm"
Finally the Action code looks like this :
public class MyAction extends ActionSupport implements ServletRequestAware {
#Action(value = "modifyServer", results = {
#Result(name = "success", location = Location.MAIN_PAGE),
#Result(name = "error", location = Location.LOGIN_PAGE) })
public String modifyServer() {
String id = request.getParameter("sssId");
System.out.println("id serveur = " + id);
return null;
}
private HttpServletRequest request;
#Override
public void setServletRequest(HttpServletRequest request) {
this.request = request;
}
}

If the input element has disabled="disabled" attribute it won't include as parameter when your form is submitted. Also rename the input element name that correspond to a parameter name. Struts2 getter/setter can be used to populate the action bean.
public void setSssId(String id){
this.id = id;
}

I'd suggest checking value of sssId being passed to the action through javascript.
<button onclick='javascript:submitMyForm();' type="button" value="Envoyer" class="btn btn-success"
>Modifier le serveur</button>
write the following javascript
function submitMyForm(){
var sssIdElement = document.getElementById("sssId");
document.form_message.action = "modifyServer.action?sssId="+sssIdElement;
document.form_message.submit();
}
