How can i get any object id from Hal representation?
Exactly i want to get this from specific user from allUser list. There is example:
{
"_embedded" : {
"users" : [ {
"login" : "user1",
"firstName" : "Bolek",
"lastName" : "Kowal",
"email" : null,
"password" : null,
"gender" : null,
"birthDate" : null,
"_links" : {
"self" : {
"href" : "http://localhost:8080/games-organizer/api/users/1"
},
"user" : {
"href" : "http://localhost:8080/games-organizer/api/users/1"
},
"roles" : {
"href" : "http://localhost:8080/games-organizer/api/users/1/roles"
}
}
}, {
"login" : "user2",
"firstName" : "Lolek",
"lastName" : "Kowalski",
"email" : null,
"password" : null,
"gender" : null,
"birthDate" : null,
"_links" : {
"self" : {
"href" : "http://localhost:8080/games-organizer/api/users/2"
},
"user" : {
"href" : "http://localhost:8080/games-organizer/api/users/2"
},
"roles" : {
"href" : "http://localhost:8080/games-organizer/api/users/2/roles"
}
}
}
Eventually how can i delete specific user using rest spring api and angular/spring? I don't know how can i do this without having id from any user(object).
Update:
I want to use this id, in invoke some method like this:
$scope.$on('deleteUser', function (event, id) {
userService.delete({id: id}).$promise.then(
function () {
// Broadcast the event to refresh the grid.
$rootScope.$broadcast('refreshUserGrid');
// Broadcast the event to display a delete message.
$rootScope.$broadcast('userDeleted');
$scope.clearForm();
},
function () {
// Broadcast the event for a server error.
$rootScope.$broadcast('error');
});
});
I want to delete some record from database in springRestAPI.
Suppose you want to delete details of user2 then you can do this :
For (var i=0;i<allUser.users.length;i++){
if(allUser.users[i].login=="user2"){
allUser.users.splice(i-1,i);
}
}

I'm currently learning about Spring Boot and am undertaking a project where users can make posts, view those posts, etc.
A user's post(s) can be viewed via http://localhost:8080/users/{user_id}/posts and http://localhost:8080/users/{user_id}/posts/{post_id}
As a result I have the following UserPostController
#RestController
#RequestMapping("/users")
public class UserPostController {
#Autowired
private UserPostService postService;
#GetMapping("/{user_id}/posts")
public List<Post> retrieveUserPosts(#PathVariable int user_id) {
return postService.retrieveUserPostList(user_id);
}
#GetMapping("/{user_id}/posts/{post_id}")
public EntityModel<Post> retrieveUserPost(#PathVariable int user_id, #PathVariable int post_id) {
return postService.retrieveUserPost(user_id, post_id);
}
#PostMapping("/{user_id}/posts")
public ResponseEntity<Object> createUserPost(#PathVariable int user_id, #Valid #RequestBody Post post) {
return postService.saveUserPost(user_id, post);
}
}
Every request to the links work correctly. For example a GET request to http://localhost:8080/users/1/posts returns [{"id":1,"description":"This is a post"},{"id":2,"description":"This is another post"}], which is the expected action.
However, for some reason I am able to visit http://localhost:8080/posts which then returns a list of all posts:
{
"_embedded" : {
"posts" : [ {
"description" : "This is a post",
"_links" : {
"self" : {
"href" : "http://localhost:8080/posts/1"
},
"post" : {
"href" : "http://localhost:8080/posts/1"
},
"user" : {
"href" : "http://localhost:8080/posts/1/user"
}
}
}, {
"description" : "This another post",
"_links" : {
"self" : {
"href" : "http://localhost:8080/posts/2"
},
"post" : {
"href" : "http://localhost:8080/posts/2"
},
"user" : {
"href" : "http://localhost:8080/posts/2/user"
}
}
}, {
"description" : "This is yet another post",
"_links" : {
"self" : {
"href" : "http://localhost:8080/posts/3"
},
"post" : {
"href" : "http://localhost:8080/posts/3"
},
"user" : {
"href" : "http://localhost:8080/posts/3/user"
}
}
} ]
},
"_links" : {
"self" : {
"href" : "http://localhost:8080/posts"
},
"profile" : {
"href" : "http://localhost:8080/profile/posts"
}
},
"page" : {
"size" : 20,
"totalElements" : 3,
"totalPages" : 1,
"number" : 0
}
}
Through HATEOAS I am able to also see available links of the format http://localhost:8080/posts/{user_id}/user which I have also not created methods for, but they still exist.
Is there a reason why these unwanted routes exist? If so how do I change this?
Thank you :)
UPDATE1: I still working on it but I can't solve it, maybe restructuring the database? I'll continue thinking but if someone has an idea it will be great to hear
Well I'm trying to get all current users friends and his own posts in a firebase query but I can't get them, always I tryed I only get one friend posts because the others are overwritten. Let me show you how my data base (JSON) is structured and how I want to display the post in the Android project Activity.
UserRef = FirebaseDatabase.getInstance().getReference().child("Users");
PostRef = FirebaseDatabase.getInstance().getReference().child("Post");
...
...
UserRef.child(currentUserID).addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot)
{
if(dataSnapshot.exists())
{
if(dataSnapshot.hasChild("Friends")){
for(DataSnapshot ds : dataSnapshot.child("Friends").getChildren()){
friendsID = ds.getKey(); //String with friendsID
DisplayAllUserPosts();
}
}...
...
private void DisplayAllUserPosts() {
Query SortPost = PostRef.orderByChild("uid").equalTo(friendsID);
FirebaseRecyclerOptions<Posts> options=new FirebaseRecyclerOptions.Builder<Posts>().setQuery(SortPost,Posts.class).build(); \\Posts class is just for getting data base Post nodes elements
FirebaseRecyclerAdapter<Posts, PostsViewHolder> firebaseRecyclerAdapter=new FirebaseRecyclerAdapter<Posts, PostsViewHolder>(options) {...
My Firebase Real Time Database is structured like this:
{
"Post" : {
"10-04-201918:32:09" : {
"counter" : 0,
"date" : "10-04-2019",
"fullname" : "Xuban Illarramendi",
"postimage" : "XXXX",
"profileimage" : "XXXX",
"status" : "",
"time" : "18:32:09",
"uid" : "FP1YJnlJBpfU5aSZlSAErLODWZl2"
},
"10-04-201921:10:06" : {
"counter" : 0,
"date" : "10-04-2019",
"fullname" : "Ander Lopez",
"postimage" : "XXXX",
"profileimage" : "XXXX",
"status" : "",
"time" : "21:10:06",
"uid" : "8wXFsw1pBRYXBVtChqY1Kqi14dy1"
}
},
"Users" : {
"8wXFsw1pBRYXBVtChqY1Kqi14dy1" : {
"Friends" : {
"FP1YJnlJBpfU5aSZlSAErLODWZl2" : {
"date" : "10-04-2019"
},
"sWQGtchFE1fvuSIfPb42ZIWVkbU2" : {
"date" : "10-04-2019"
}
},
"country" : "Spain",
"dob" : "none",
"fullname" : "Ander Lopez",
"gender" : "none",
"profileimage" : "XXXX",
"relationshipstatus" : "none",
"status" : "",
"username" : "anderlopz"
},
"FP1YJnlJBpfU5aSZlSAErLODWZl2" : {
"Friends" : {
"8wXFsw1pBRYXBVtChqY1Kqi14dy1" : {
"date" : "10-04-2019"
},
"sWQGtchFE1fvuSIfPb42ZIWVkbU2" : {
"date" : "10-04-2019"
}
},
"country" : "Spain",
"dob" : "none",
"fullname" : "Xuban Illarramendi",
"gender" : "none",
"profileimage" : "XXXX",
"relationshipstatus" : "none",
"status" : "",
"username" : "xuban"
},
"sWQGtchFE1fvuSIfPb42ZIWVkbU2" : {
"Friends" : {
"8wXFsw1pBRYXBVtChqY1Kqi14dy1" : {
"date" : "10-04-2019"
},
"FP1YJnlJBpfU5aSZlSAErLODWZl2" : {
"date" : "10-04-2019"
}
},
"country" : "Spain",
"dob" : "none",
"fullname" : "Unai Lopez",
"gender" : "none",
"profileimage" : "XXXX",
"relationshipstatus" : "none",
"status" : "",
"username" : "unailopz"
}
}
}
So my real problem is that he displays only the last friend posts, how can I make a query that contains all my friendsID without overwritting the previous friendsID?
I am building an REST API with Spring Boot. The question is really simple, how can I enable pagination for dependency request?
This how the results look for a non dependency request http://localhost:8080/dimensionAttributes:
{
"_embedded" : {
"dimensionAttribute" : [ {
"name" : "SollFreitag",
"description" : "Sollstunden Freitags",
"dataType" : "DEC",
"hasHistory" : true,
"hasTrigger" : null,
"allowInterface" : true,
"readOnly" : null,
"discrete" : null,
"mandatory" : false,
"_links" : {
"self" : {
"href" : "http://localhost:8080/dimensionAttributes/20"
},
"dimensionAttribute" : {
"href" : "http://localhost:8080/dimensionAttributes/20"
},
"dimension" : {
"href" : "http://localhost:8080/dimensionAttributes/20/dimension"
},
"dimensionAttributeValue" : {
"href" : "http://localhost:8080/dimensionAttributes/20/dimensionAttributeValue"
}
}
} ]
},
"_links" : {
"first" : {
"href" : "http://localhost:8080/dimensionAttributes?page=0&size=20"
},
"self" : {
"href" : "http://localhost:8080/dimensionAttributes{?page,size,sort}",
"templated" : true
},
"next" : {
"href" : "http://localhost:8080/dimensionAttributes?page=1&size=20"
},
"last" : {
"href" : "http://localhost:8080/dimensionAttributes?page=1&size=20"
},
"profile" : {
"href" : "http://localhost:8080/profile/dimensionAttributes"
},
"search" : {
"href" : "http://localhost:8080/dimensionAttributes/search"
}
},
"page" : {
"size" : 20,
"totalElements" : 35,
"totalPages" : 2,
"number" : 0
}
}
But running an dependency request (in this case its "dimensionAttributeValue" ) http://localhost:8080/dimensionAttributes/20/dimensionAttributeValue, the page section, as well as the next url and other links are missing.
{
"_embedded" : {
"dimensionAttributeValue" : [ {
"chrValue" : "Mihal, Matus",
"intValue" : null,
"decValue" : null,
"datValue" : null,
"startDate" : null,
"_links" : {
"self" : {
"href" : "http://localhost:8080/dimensionAttributeValues/18993"
},
"dimensionAttributeValue" : {
"href" : "http://localhost:8080/dimensionAttributeValues/18993"
},
"lstValue" : {
"href" : "http://localhost:8080/dimensionAttributeValues/18993/lstValue"
},
"dimensionAttribute" : {
"href" : "http://localhost:8080/dimensionAttributeValues/18993/dimensionAttribute"
},
"masterData" : {
"href" : "http://localhost:8080/dimensionAttributeValues/18993/masterData"
}
}
} ]
},
"_links" : {
"self" : {
"href" : "http://localhost:8080/dimensionAttributes/1/dimensionAttributeValue?page=0,&size=1"
}
}
}
I have simple Spring Boot application. My controller looks like this:
#RequestMapping(value = "/", method = RequestMethod.GET)
public List<Employee> getAllEmployees() {
return employeeRepository.findAll();
}
This code produce this json:
{
"_embedded" : {
"employees" : [ {
"firstName" : "firstName1",
"lastName" : "lastName1",
"_links" : {
"self" : {
"href" : "http://localhost:8080/employees/1"
},
"employee" : {
"href" : "http://localhost:8080/employees/1"
}
}
}, {
"firstName" : "firstName 1",
"lastName" : "lastName 1",
"_links" : {
"self" : {
"href" : "http://localhost:8080/employees/2"
},
"employee" : {
"href" : "http://localhost:8080/employees/2"
}
}
}, {
"firstName" : "firstName 3",
"lastName" : "lastName 3",
"_links" : {
"self" : {
"href" : "http://localhost:8080/employees/4"
},
"employee" : {
"href" : "http://localhost:8080/employees/4"
}
},
"_links" : {
"self" : {
"href" : "http://localhost:8080/employees"
},
"profile" : {
"href" : "http://localhost:8080/profile/employees"
}
},
"page" : {
"size" : 20,
"totalElements" : 7,
"totalPages" : 1,
"number" : 0
}
}
But I need something like this:
[
{
"firstName" : "firstName1",
"lastName" : "lastName1",
},
{
"firstName" : "firstName2",
"lastName" : "lastName2",
},
]
The solution is removing spring-boot-starter-data-rest module.
How to get expected output below where OrderProjection uses ItemProjection to render Items using Spring Data REST
GET /orders/1?projection=with_items
Projections :
#Projection(name = "summary", types = Item.class)
public interface ItemProjection {
String getName();
}
#Projection(name = "with_item", types = Order.class)
public interface OrderProjection {
LocalDateTime getOrderedDate();
Status getStatus();
Set<ItemProjection> getItems(); // this is marshalling as Set<Item> (full Item graph)
}
Currently getting as output:
{
"status" : "PAYMENT_EXPECTED",
"orderedDate" : "2014-11-09T11:33:02.823",
"items" : [ {
"name" : "Java Chip",
"quantity" : 1,
"milk" : "SEMI",
"size" : "LARGE",
"price" : {
"currency" : "EUR",
"value" : 4.20
}
} ],
"_links" : {
"self" : {
"href" : "http://localhost:8080/orders/1{?projection}",
"templated" : true
},
"restbucks:items" : {
"href" : "http://localhost:8080/orders/1/items"
},
"curies" : [ {
"href" : "http://localhost:8080/alps/{rel}",
"name" : "restbucks",
"templated" : true
} ]
}
}
Expected Output:

You're running into DATAREST-394 which has been fixed a few days a go and will be making it into 2.2.2 and 2.3 RC1. It's already available in the snapshots for said versions, feel free to give them a spin.
