"Content type 'application/json;charset=UTF-8' not supported" in Spring Rest application

Question

When I do a POST request on localhost:8080/api/users to create a new user I get the following error :

{     "timestamp": "2018-05-28T09:44:55.704+0000",     "status": 415,     "error": "Unsupported Media Type",     "message": "Content type 'application/json;charset=UTF-8' not supported",     "path": "/api/users/" } 

The is the request's body, JSON (application/json) is selected. It gives the same error even if I remove the Roles and keep it null.

The header's content type is application/json as well.

This is my controller :

@PostMapping("/api/users" ) public User createUser(@Valid @RequestBody User user) {     securityService.autologin(user.getUsername(), user.getPassword());     return userService.createUser(user); } 

createUser function in UserService :

public User createUser(@Valid @RequestBody User user) {     user.setPassword(bCryptPasswordEncoder.encode(user.getPassword()));     user.setRoles(new HashSet<>(roleRepository.findAll()));     return userRepository.save(user); }

This is my User class :

@Entity @Table(name = "user") @EntityListeners(AuditingEntityListener.class) @JsonIgnoreProperties(value = {"createdAt", "updatedAt"},                        allowGetters = true) public class User implements Serializable{      private static final long serialVersionUID = 1L;       public User() {         super();         // TODO Auto-generated constructor stub     }      @Id     @Column(name = "user_id")     @GeneratedValue(strategy = GenerationType.IDENTITY)     private long id;      @Column(name = "user_name")     private String name;      @Column(name = "user_email")     private String email;      @Column(name = "user_password")     @NotBlank     private String password;      @Column(name = "user_status")     private String status;      @Column(name = "user_tel")     private String tel;      @Column(name = "user_confirmation")     private String confirmation;      @Column(name = "user_birth_date")     @Temporal(TemporalType.DATE)     private Date birth_date;      @Column(nullable = false, updatable = false)     @Temporal(TemporalType.TIMESTAMP)     @CreatedDate     private Date createdAt;      @Column(nullable = false)     @Temporal(TemporalType.TIMESTAMP)     @LastModifiedDate     private Date updatedAt;      @JsonManagedReference     @ManyToMany     @JoinTable(name = "user_role", joinColumns = @JoinColumn(name = "user_id"), inverseJoinColumns = @JoinColumn(name = "role_id"))     private Set<Role> roles;      @Column(name = "username")     @NotBlank     private String username;      public long getId() {         return id;     }      public void setId(long id) {         this.id = id;     }      public String getName() {         return name;     }      public void setName(String name) {         this.name = name;     }      public String getUsername() {         return username;     }      public void setUsername(String username) {         this.username = username;     }      public String getEmail() {         return email;     }      public void setEmail(String email) {         this.email = email;     }      public String getPassword() {         return password;     }      public void setPassword(String password) {         this.password = password;     }      public String getStatus() {         return status;     }      public void setStatus(String status) {         this.status = status;     }      public String getTel() {         return tel;     }      public void setTel(String tel) {         this.tel = tel;     }      public String getConfirmation() {         return confirmation;     }      public void setConfirmation(String confirmation) {         this.confirmation = confirmation;     }      public Date getBirth_date() {         return birth_date;     }      public void setBirth_date(Date birth_date) {         this.birth_date = birth_date;     }      public Date getCreatedAt() {         return createdAt;     }      public Date getUpdatedAt() {         return updatedAt;     }      public void setUpdatedAt(Date updatedAt) {         this.updatedAt = updatedAt;     }      public Set<Role> getRoles() {         return roles;     }      public void setRoles(Set<Role> roles) {         this.roles = roles;     } } 

Answer 1

I was able to solve it by removing @JsonManagedReference.
