Java Spring-415不支持的媒体类型

Question

Here is my Controller:

@RestController
public class UserController {

    @RequestMapping(value = "/test", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
    public User someName(@RequestBody  User user){
        System.out.println(user.toString());
        return user;
    }

}

User class:

@Entity
@Table(name = "user")
public class User {

    @Id @GeneratedValue
    @Column(name = "id")
    private Integer id;

    private String name;
    private String secondname;
    private String email;

    public User() {
    }

    public User(Integer id, String name, String secondname, String email) {
        this.id = id;
        this.name = name;
        this.secondname = secondname;
        this.email = email;
    }

    public User(String name, String secondname, String email) {
        this.name = name;
        this.secondname = secondname;
        this.email = email;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    @Column(name = "name")
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Column(name = "secondname")
    public String getSecondname() {
        return secondname;
    }

    public void setSecondname(String secondname) {
        this.secondname = secondname;
    }

    @Column(name = "email")
    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Override
    public String toString() {
        return new StringBuilder().append(this.name).append(", ").append(this.secondname).append(", ")
                .append(this.email).toString();
    }
}

When I want to post in in postman:

{
    "name": "test",
    "secondname": "test",
    "email": "test@test.pl"
}

I have an error: 415 Unsupported Media type More precisely I have: The server refused this request because the request entity is in a format not supported by the requested resource for the requested method.

In postman I choose raw and JSON (application/json) . As headers I have written: Content-Type as key and application/json as value.

Somebody have any idea what I'm doing wrong?

Answer 1

您可以使用chrome的inspect命令查看邮递员的请求的HTTP标头。检查content-Type是否正确。

Answer 2

This is so common in spring. Make your entity serializable.
