Content type 'multipart/form-data;boundary=----WebKitFormBoundary...' not supported Spring - spring

Spring 5.0.7: MVC, Data, Security.
I configure multipartResolver.
I send next Ajax request:
$.ajax({
type: 'POST',
cache: false,
processData: false,
contentType: false,
url: '/api/v1/category/add',
data: new FormData(form)
}).done(result=>{console.log(result);}).fail(result=>{
console.error('ERROR:', result.responseJSON.httpStatus, result.responseJSON.message, result);
self.toast.error('API Error.');
});
But there is an error: Content type 'multipart/form-data;boundary=----WebKitFormBoundary6xBCDjCtYYuUVR5c' not supported
why? i don't understand why error happen.
Controller:
#RestController
#Secured("hasRole('ADMIN')")
#RequestMapping(value = "/api/v1")
public class ApiController {
private static final Logger LOGGER = LogManager.getLogger(ApiController.class);
#PostMapping(value = "/category/add", consumes = MediaType.MULTIPART_FORM_DATA_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
private Response categoryAdd(Response response, #RequestBody CategoryAddForm categoryAddForm) {
LOGGER.info(categoryAddForm.toString());
return response;
}
}
CategoryAddForm:
public class CategoryAddForm {
private String name;
private String description;
private MultipartFile preview;
public CategoryAddForm() { }
public CategoryAddForm(String name, String description, MultipartFile preview) {
this.name = name;
this.description = description;
this.preview = preview;
}
public String getName() {
return name;
}
public String getDescription() {
return description;
}
public MultipartFile getPreview() {
return preview;
}
}
I do not know what else to write, but SO requires more text. (

In your controller, use #RequestParam instead of #RequestBody.
Was having the same issue and it worked for me.
See this SO answer for more info

You need to add this maven dependency commons-fileupload:commons-fileupload:1.3.x
and declare MultipartResolver bean
#Bean(name = "multipartResolver")
public CommonsMultipartResolver multipartResolver() {
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
multipartResolver.setMaxUploadSize(100000);
return multipartResolver;
}
Above method is for Spring controllers. If you want to do for Async Spring controllers refer this article.

Hope it helps!

415--Unsupported Media Type in Spring

I am getting unsupported mediatype error.
My User Profile class looks like this
Class UserProfile{
private int age;
private String name,
private String currenecy;
}
And this is the method in controller
#RequestMapping(value = "/Create", method=RequestMethod.POST,consumes=MediaType.APPLICATION_JSON_VALUE, produces=MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<UserProfileResponse> createUserProfile(#RequestBody UserProfile userProfile)
{
UserProfileResponse userProfileResponse = new UserProfileResponse();
int id = createUserProfileData(userProfile)
userProfileResponse.setId(id);
return new ResponseEntity<UserProfileResponse>(userProfileResponse,HTTPStatus.OK);
}
I am trying to send the request through POSTMAN but getting
Error 415--Unsupported Media Type
My Request in POstman looks like this
Content-Type:application/json
Accept:application/json
Method is : POST
{
"age":28,
"name":"Sam",
"currency": "INR"
}
Suggest me what I am missing?
Don't forget to select "JSON" format, filled in arbitrary JSON string in the textarea.
Also use either Accept or Content-type at a time.
If that doesn't work then can you check like below by removing consumes and adding headers manually.
#RequestMapping(value = "/Create", method=RequestMethod.POST, headers = "Accept=application/json",produces=MediaType.APPLICATION_JSON_VALUE)
I could see the response coming back with your code. I am deliberately returning the same object just to test the connectivity. Following is my code:
#RequestMapping(value = "/create", method= RequestMethod.POST,consumes= MediaType.APPLICATION_JSON_VALUE, produces=MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<UserProfile> createUserProfile(#RequestBody UserProfile userProfile)
{
System.out.println("Got request");
return new ResponseEntity<>(userProfile, HttpStatus.OK);
}
Used getter and setter in UserProfile
public class UserProfile {
private int age;
private String name;
private String currenecy;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCurrenecy() {
return currenecy;
}
public void setCurrenecy(String currenecy) {
this.currenecy = currenecy;
}
}
Finally after after spending some time.. I figured out why it was not working.
In my java based spring configuration file I missed "#EnableWebMvc".
After adding it, my problem got resolved.
#Configuration
**#EnableWebMvc** // This annotation was missing.
#ComponentScan(basePackages="com.hemant.*")
public class TestConfiguration {}

RestController return CompletableFuture<List>

I try to create rest controller which return all products. I want to use CompletableFuture to return list with product.
I have async request to spring data
#Async
#Query("select product from Product product")
CompletableFuture<List<Product>> findAllAsync();
and controller
#Async
#RequestMapping(path = "/products", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
public #ResponseBody
CompletableFuture<List<ProductData>> loadAllProducts2(){
return this.products.findAllAsync()
.thenApplyAsync(Collection::stream)
.thenApplyAsync(s -> s.map(Product::data))
.thenApplyAsync(s -> s.collect(Collectors.toList()));
}
ProgramData is simple DTO:
public final class ProductData {
private final String name;
private final String label;
public ProductData(String name, String label) {
this.name = name;
this.label = label;
}
public String getName() {
return this.name;
}
public String getLabel() {
return this.label;
}
}
Spring return nothing, in log output is :
o.s.b.a.e.mvc.EndpointHandlerMapping : Did not find handler method for [/products]
Any ideas what's wrong ?
I removed target directory and It did work.

Java Spring 4 (Annotated) Rest Controller not being hit by REST Client tool in Firefox

Hi,
I have a problem that is very confusing for me because the mapping should work and it looks like it does map when the Spring Boot is started in debug mode. I don't know where else I can check for an obvious solution to this problem.
Here is the application.properties:
server.port=8082
server.contextPath = /
Here is the SpringBootInitializer class that adds a further "/api" to the >Servlet registration:
public class App extends SpringBootServletInitializer {
#Bean
public DispatcherServlet dispatcherServlet() {
return new DispatcherServlet();
}
#Bean
public ServletRegistrationBean dispatcherServletRegistration() {
final ServletRegistrationBean registration = new ServletRegistrationBean(dispatcherServlet(), "/api/*");
final Map<String, String> params = new HashMap<String, String>();
params.put("contextClass", "org.springframework.web.context.support.AnnotationConfigWebApplicationContext");
params.put("contextConfigLocation", "org.spring.sec2.spring");
params.put("dispatchOptionsRequest", "true");
registration.setInitParameters(params);
registration.setLoadOnStartup(1);
return registration;
}
//
#Override
protected SpringApplicationBuilder configure(final SpringApplicationBuilder application) {
return application.initializers(new MyApplicationContextInitializer()).sources(App.class);
}
public static void main(final String... args) {
new SpringApplicationBuilder(App.class).initializers(new MyApplicationContextInitializer()).run(args);
}
}
Here is the Controler which adds a further "users" to the mapping. The method >which I have set a debug point is the findAll and requires no futher mapping to >get to it (i.e. the root of /users/:
#Controller
#RequestMapping(value = users)
public class UserController extends AbstractController<User> {
#Autowired
private IUserService userService;
public UserController() {
super(User.class);
}
// API
// find
#RequestMapping(method = RequestMethod.GET)
#ResponseBody
public void getItsWorking() {
System.out.println("It's Working!!!");
}
}
Here is the User entity:
#Entity
public class User implements IEntity {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name="user_id")
private Long user_id;
#Column(name = "username", unique = true, nullable = false)
private String name;
#Column(unique = true, nullable = false)
private String email;
#Column(nullable = false)
private String password;
#Column(nullable = false)
private Boolean locked;
public User() {
super();
}
public User(final String nameToSet, final String passwordToSet, /*final
Set<Role> rolesToSet,*/ final Boolean lockedToSet) {
super();
name = nameToSet;
password = passwordToSet;
locked = lockedToSet;
}
// API
public Long getId() {
return user_id;
}
public void setId(final Long idToSet) {
user_id = idToSet;
}
public String getName() {
return name;
}
public void setName(final String nameToSet) {
name = nameToSet;
}
public String getEmail() {
return email;
}
public void setEmail(final String emailToSet) {
email = emailToSet;
}
public String getPassword() {
return password;
}
public void setPassword(final String passwordToSet) {
password = passwordToSet;
}
public Boolean getLocked() {
return locked;
}
public void setLocked(final Boolean lockedToSet) {
locked = lockedToSet;
}
}
Here is the output on my Spring Boot debug when it starts up:
Mapped "{[/users],methods=[GET]}" onto public
java.util.List<org.um.persistence.model.User>
org.um.web.controller.UserController.findAll(javax.servlet.http.HttpServletRequest)
So, it looks like it is mapping correctly, but when I hit it using the Rest >Client tool add on in Firefox, I get the following when doing a "GET" on the >following url: http://localhost:8082/api/users using Content-Type: application/json in my header .
What is going on? Very confused.
You should put a #RequestMapping("/api") on you class, and a #RequestMapping("/users") on your method (that should preferably return something to the client).
This ways your endpoint will be exposed as /api/users and you will be able to easily add further endpoints under /api/* into this class.

#ResourceMapping that accepts JSON from Ajax request

I'm searching how I can interprete a JSON parameter in my #ResourceMapping in Spring Portlet MVC. When I add #RequestBody, I got the message: #RequestBody is not supported... Really stuck on this one.
I have this:
View side:
<portlet:resourceURL var="getTest" id="ajaxTest" ></portlet:resourceURL>
<p>
<button onClick="executeAjaxTest();">Klik mij!</button>
<button onClick="$('#ajaxResponse').html('');">Klik mij!</button>
</p>
<p>
<h3>Hieronder het antwoord:</h3>
<h4 id="ajaxResponse"></h4>
</p>
<script>
function executeAjaxTest() {
var jsonObj = {
user: "Korneel",
password: "testpassword",
type: {
testParam: "test",
}
}
console.debug(JSON.stringify(jsonObj));
$.ajax({
dataType: "json",
contentType:"application/json",
mimeType: 'application/json',
url:"<%=getTest%>",
data:JSON.stringify(jsonObj),
success : function(data) {
$("#ajaxResponse").html(data['testString']);
}
});
}
</script>
Controller side:
#ResourceMapping(value="ajaxTest")
#ResponseBody
public void ajaxTestMethod(ResourceRequest request, ResourceResponse response) throws IOException, ParseException {
LOGGER.debug("ajax method");
JSONObject json = JSONFactoryUtil.createJSONObject();
json.put("testString", "Ik ben succesvol verstuurd geweest!");
response.getWriter().write(json.toString());
}
How can I use the spring magic to auto map this JSON data to my own model?
Note: It's Spring Portlet MVC, not regular Spring MVC..
#ResponseBody annotation is not supported out of the box in Spring MVC portlet framework, but you can implement #ResponseBody handling yourself.
We do it by implementing custom view type and model and view resolver.
Implement custom model and view resolver (ModelAndViewResolver), let's say JsonModelAndViewResolver.
In resolveModelAndView method, check whether controller method has #ResponseBody annotation (or more specific condition to identify JSON output - e.g. annotation + required supported mime type).
If yes, return your custom View implementation - let's say SingleObjectJson view (extending AbstractView).
Pass your to-be-serialized object to the view instance.
The view will serialize the object to JSON format and write it to the response (by using Jackson, Gson or other framework in renderMergedOutputModel method).
Register the new resolver as AnnotationMethodHandlerAdapter.customModelAndViewResolvers.
You need to build your json object like this:
var jsonObj = {
user: "Korneel",
password: "testpassword",
"type.testParam" : "test"
};
$.ajax({
dataType: "json",
contentType:"application/json",
mimeType: 'application/json',
url:"<%=getTest%>",
data:jsonObj,
success : function(data) {
$("#ajaxResponse").html(data['testString']);
}
});
In your Controller you should use the #ModelAttribute annotation:
#ModelAttribute(value = "jsonObj")
public JsonObjCommand obtenerJsonObjCommand() {
JsonObjCommand jsonObjCommand = new JsonObjCommand();
return jsonObjCommand;
}
#ResourceMapping(value = "ajaxTest")
public void ajaxTestMethod(
ResourceRequest request,
ResourceResponse response,
#ModelAttribute(value = "jsonObj") JsonObjCommand jsonObjCommand)
throws IOException, ParseException {
LOGGER.debug("USER: " + jsonObjCommand.getUser());
LOGGER.debug("Password: " + jsonObjCommand.getPassword());
LOGGER.debug("TestParam: " + jsonObjCommand.getType().getTestParam());
LOGGER.debug("ajax method");
JSONObject json = JSONFactoryUtil.createJSONObject();
json.put("testString", "Ik ben succesvol verstuurd geweest!");
response.getWriter().write(json.toString());
}
Don't forget your beans:
public class JsonObjCommand {
private String user;
private String password;
private TypeJson type;
public String getUser() {
return user;
}
public void setUser(String user) {
this.user = user;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public TypeJson getType() {
return type;
}
public void setType(TypeJson type) {
this.type = type;
}
}
public class TypeJson {
private String testParam;
public String getTestParam() {
return testParam;
}
public void setTestParam(String testParam) {
this.testParam = testParam;
}
}
According to the documentation, #RequestBody is only supported in Servlet environments, not Portlet environments (same for #ResponseBody). So it seems you can't use that functionality.

receiving json and deserializing as List of object at spring mvc controller

My code is as below:
controller
#RequestMapping(value="/setTest", method=RequestMethod.POST, consumes="application/json")
public #ResponseBody ModelMap setTest(#RequestBody List<TestS> refunds, ModelMap map) {
for(TestS r : refunds) {
System.out.println(r.getName());
}
// other codes
}
TestS pojo
public class TestS implements Serializable {
private String name;
private String age;
//getter setter
}
Json request
var z = '[{"name":"1","age":"2"},{"name":"1","age":"3"}]';
$.ajax({
url: "/setTest",
data: z,
type: "POST",
dataType:"json",
contentType:'application/json'
});
It's giving this error
java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to com.air.cidb.entities.TestS
I am using spring 3.1.2 and jackson 2.0.4
Edit: I want to receive list of TestS objects at my controller method, and process them. I am not able to find if I am sending wrong json or my method signature is wrong.
Here is the code that works for me. The key is that you need a wrapper class.
public class Person {
private String name;
private Integer age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
#Override
public String toString() {
return "Person [name=" + name + ", age=" + age + "]";
}
A PersonWrapper class
public class PersonWrapper {
private List<Person> persons;
/**
* #return the persons
*/
public List<Person> getPersons() {
return persons;
}
/**
* #param persons the persons to set
*/
public void setPersons(List<Person> persons) {
this.persons = persons;
}
}
My Controller methods
#RequestMapping(value="person", method=RequestMethod.POST,consumes="application/json",produces="application/json")
#ResponseBody
public List<String> savePerson(#RequestBody PersonWrapper wrapper) {
List<String> response = new ArrayList<String>();
for (Person person: wrapper.getPersons()){
personService.save(person);
response.add("Saved person: " + person.toString());
}
return response;
}
The request sent is json in POST
{"persons":[{"name":"shail1","age":"2"},{"name":"shail2","age":"3"}]}
And the response is
["Saved person: Person [name=shail1, age=2]","Saved person: Person [name=shail2, age=3]"]
This is not possible the way you are trying it. The Jackson unmarshalling works on the compiled java code after type erasure. So your
public #ResponseBody ModelMap setTest(#RequestBody List<TestS> refunds, ModelMap map)
is really only
public #ResponseBody ModelMap setTest(#RequestBody List refunds, ModelMap map)
(no generics in the list arg).
The default type Jackson creates when unmarshalling a List is a LinkedHashMap.
As mentioned by #Saint you can circumvent this by creating your own type for the list like so:
class TestSList extends ArrayList<TestS> { }
and then modifying your controller signature to
public #ResponseBody ModelMap setTest(#RequestBody TestSList refunds, ModelMap map) {
#RequestMapping(
value="person",
method=RequestMethod.POST,
consumes="application/json",
produces="application/json")
#ResponseBody
public List<String> savePerson(#RequestBody Person[] personArray) {
List<String> response = new ArrayList<String>();
for (Person person: personArray) {
personService.save(person);
response.add("Saved person: " + person.toString());
}
return response;
}
We can use Array as shown above.
Solution works very well,
public List<String> savePerson(#RequestBody Person[] personArray)
For this signature you can pass Person array from postman like
[
{
"empId": "10001",
"tier": "Single",
"someting": 6,
"anything": 0,
"frequency": "Quaterly"
}, {
"empId": "10001",
"tier": "Single",
"someting": 6,
"anything": 0,
"frequency": "Quaterly"
}
]
Don't forget to add consumes tag:
#RequestMapping(value = "/getEmployeeList", method = RequestMethod.POST, consumes="application/json", produces = "application/json")
public List<Employee> getEmployeeDataList(#RequestBody Employee[] employeearray) { ... }
I believe this will solve the issue
var z = '[{"name":"1","age":"2"},{"name":"1","age":"3"}]';
z = JSON.stringify(JSON.parse(z));
$.ajax({
url: "/setTest",
data: z,
type: "POST",
dataType:"json",
contentType:'application/json'
});
For me below code worked, first sending json string with proper headers
$.ajax({
type: "POST",
url : 'save',
data : JSON.stringify(valObject),
contentType:"application/json; charset=utf-8",
dataType:"json",
success : function(resp){
console.log(resp);
},
error : function(resp){
console.log(resp);
}
});
And then on Spring side -
#RequestMapping(value = "/save",
method = RequestMethod.POST,
consumes="application/json")
public #ResponseBody String save(#RequestBody ArrayList<KeyValue> keyValList) {
//Saving call goes here
return "";
}
Here KeyValue is simple pojo that corresponds to your JSON structure also you can add produces as you wish, I am simply returning string.
My json object is like this -
[{"storedKey":"vc","storedValue":"1","clientId":"1","locationId":"1"},
{"storedKey":"vr","storedValue":"","clientId":"1","locationId":"1"}]
