Why is the controller saving the user with null property fields

Why is the controller saving the user with null property fields - java

Basically, Spring crashes with this error "value [null]; codes [NotNull.user.email,NotNull.email,NotNull.java.lang.String,NotNull]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [user.email,email]; arguments []; default message [email]]; default message [must not be null], Field error in object 'user' on field 'firstName': rejected value [null]; codes" everytime I try to submit the completeProfile form. So, naturally, I looked at what data was saved after clicking submit on form. It turns out that the User object saved was having all the submitted property from the form as null. I checked inside the controller what was passed inside, all submitted properties from the form were null. Why does this happen?

Updating user through html form removes user's role in database

As the title says, I'm having difficulty in my Java + Spring/Hibernate project where when I go to update and Employee or Customers information, it removes their role from the employee_roles/customer_roles table in the database.
I had this same issue with the username being removed however, I was able to work around this by creating a hidden input form for the username in the html page.
The files for running this project can be found below, if you find that you can't get it to work properly on Mac, that may be because you will need to change the jdbc.url to just: jdbc:mysql://localhost:3306/spring_pie_deal

Thymeleaf not able to post collections / lists of objects

I'm creating a web-application with spring MVC, hibernate and thymeleaf.
I have a page where I can manage users, on this page you should be able to place and remove users from groups.
I am doing this with 2 multiple select boxes.
I added a jquery script what handles the movement of users from the one select box to the other one.
But when i submit, my Group.users object list is empty and I do not get any exceptions.
Does anyone has some advice?
Thanks in advance.
Edit
I just discovered that all thymeleaf attributes inside the html tag "option", aren't compiled. Except for the th:each attr.
So it's pretty clear the problem is in my thymeleaf file.

Whenever my JSP calling this java class, it only can detect the original element. I have added a new element - mydate and it is like forever cannot detect it.
Below is the error code.
pe Exception report
messageInternal Server Error
descriptionThe server encountered an internal error that prevented it

I have try to delete the java class and recreate again but still, the JSP only can detect for my first 16 elements and not any new added element.
Any solutions? Thanks

this.mydate = mydate;
}
It should be setMydate and getMydate. isn't it ?
Update -
It is case sensative.
public String mydate;
this should be
public String myDate;
Your JSP should be abc.myDate and not abc.mydate
<td><c:out value="${abc.mydate}" /></td>

Retrieve embedded documents from mongoDB

The below data is stored in MongoDB. I am using Spring-Data and storing the data into mongoDB.
If I want to retrieve the fields ("id" or "Name") I can able to do, but if I want to retrieve the sub fields ("firstName" or "lastName")I can't.
(eg.)If I want to retrieve sub field "lastName" from the below data I can't.Kindly help me in this regard.
Thanks in advance.
Data Stored in MongoDB:
{
"id":101,
"name": {"firstName":"Mark",
"lastName":"Antony"
}
}
The Code I am using is:
PersonService.java
public List<Audit> searchPerson(Audit audit)
{
List<NameDetails> name=audit.getName();
return mongoTemplate.find(new Query(Criteria.where("name.lastName").is(name.get(0))), Audit.class,COLLECTION_NAME);
}
PersonController.java
#RequestMapping(value = "/person/search", method = RequestMethod.GET)
public String search(#ModelAttribute Audit audit, ModelMap model) {
model.addAttribute("personList", personService.searchPerson(audit));
return "output";
}
Audit.java
#Document
public class Audit {
#Id
private String id;
private List<NameDetails> name;
public String getId() {
System.out.println("Person: getId");
return id;
}
public void setId(String id) {
System.out.println("Person: setId");
this.id = id;
}
public List<NameDetails> getName() {
System.out.println("Audit: getName");
return name;
}
public void setName(List<NameDetails> name) {
System.out.println("Audit: setName");
this.name = name;
}
}
NameDetails.java
package com.register.mongo.model;
public class NameDetails {
private String firstName;
private String lastName;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
System.out.println("NameDetails: setFirstName");
this.firstName = firstName;
}
public String getLastName() {
System.out.println("NameDetails: getLastName");
return lastName;
}
public void setLastName(String lastName) {
System.out.println("NameDetails: setLastName");
this.lastName = lastName;
}
}
(output.jsp)UI Page
<form action="person/search" method="get">
<table>
<tr><td>
<label>Name</label>
<input type="text" id="lastName" name="lastName"/>
</td></tr>
<tr><td>
<input type="submit" value="Search"/>
</td></tr>
</table>
</form>
<table border="2">
<c:forEach var="person" items="${personList}">
<tr>
<td>${person.id}</td>
</tr>
<tr>
<td>${person.lastName}</td>
</tr>
</c:forEach>
</table>

Change
return mongoTemplate.find(
new Query(Criteria.where("name.lastName").is(name.get(0))),
Audit.class,COLLECTION_NAME);
to
return mongoTemplate.find(
new Query(Criteria.where("name.lastName").is(name.get(0).getLastName())),
Audit.class,COLLECTION_NAME);
You are trying to use the entire NameDetails instead of just the last name.

Spring form send null model object to database

I want to send data from form to PostgreSQL. When I send data by form, hibernate save (by save() method) blank record .. I did it manually (for test) without using form and then everything is ok.
Spitter.class (entity for user)
#Entity
#Table(name="spitter")
public class Spitter implements Serializable {
private static final long serialVersionUID = 829803238866007413L;
#Id
//#SequenceGenerator(name = "hibernate_sequence")
#GeneratedValue(strategy=GenerationType.AUTO) #Column(name="spitter_id")
private Long id;
#Column(unique=true) #Size(min=3, max=20) #Pattern(regexp = "^[a-zA-Z0-9]+$", message="Nie poprawna nazwa uzytkownika.")
private String username;
#Size(min=5, max=15, message="Haslo musi miec minimum 5 znakow.")
private String password;
#Size(min=3, max=25, message="Blad w imieniu i nazwisku.")
private String fullName;
#OneToMany(mappedBy="spitter")
private List<Spittle> spittles;
#Email(message="Nie poprawny adres email.")
private String email;
private boolean updateByEmail;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getFullName() {
return fullName;
}
public void setFullName(String fullName) {
this.fullName = fullName;
}
public List<Spittle> getSpittles() {
return spittles;
}
public void setSpittles(List<Spittle> spittles) {
this.spittles = spittles;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public void setUpdateByEmail(boolean updateByEmail) {
this.updateByEmail = updateByEmail;
}
public boolean isUpdateByEmail() {
return updateByEmail;
}
#Override
public boolean equals(Object obj) {
Spitter other = (Spitter) obj;
return other.fullName.equals(fullName) && other.username.equals(username) && other.password.equals(password);
}
#Override
public int hashCode() {
// TODO Auto-generated method stub
return super.hashCode();
}
}
SpitterController.class
createSpitterProfile - shows form (edit.jsp) and sends model object (spitter) to form
addSpitterFromForm - receives binding data from form and save it to database and redirects to simply user profile
showSpitterProfile - there is of course null model object exception
#Controller
#RequestMapping("/spitters")
public class SpitterController {
private final SpitterService spitterService;
#Inject //#Autowired
public SpitterController(SpitterService spitterService) {
this.spitterService = spitterService;
}
//...
#RequestMapping(method = RequestMethod.GET, params = "new")
public String createSpitterProfile(Model model) {
model.addAttribute("spitter", new Spitter());
return "spitters/edit";
}
#RequestMapping(method = RequestMethod.POST)
public String addSpitterFromForm(#Valid Spitter spitter, BindingResult bindingResult) {
if(bindingResult.hasErrors())
return "spitters/edit";
spitterService.saveSpitter(spitter);
return "redirect:/spitters/" + spitter.getUsername();
}
#RequestMapping(value="/{username}", method = RequestMethod.GET)
public String showSpitterProfile(#PathVariable String username, Model model) {
model.addAttribute(spitterService.getSpitter(username));
return "spitters/view";

and blank saved record to Postgres..

Try adding #modelattribute in this method .It fill fetch the required model object.
#RequestMapping(method = RequestMethod.POST)
public String addSpitterFromForm(**#ModelAttribute("spitter")** #Valid Spitter spitter, BindingResult bindingResult) {
if(bindingResult.hasErrors())
return "spitters/edit";
spitterService.saveSpitter(spitter);
return "redirect:/spitters/" + spitter.getUsername();
}
and just to check if it is getting the values from form,syso some values like syso(spitter.getUserName) to check if values are coming.
ALso, I believe that you are making a constructor and passing service to it ,so there is no need of #Inject
#Inject //#Autowired///Why are you injecting it if it is a constructor?
public SpitterController(SpitterService spitterService) {
this.spitterService = spitterService;
}

You have enctype="multipart/form-data in your FORM,
Check that you have something like that in your App-servlet.xml:
<bean id="multipartResolver" class=
"org.springframework.web.multipart.commons.CommonsMultipartResolver"
p:maxUploadSize="500000" />
