Spring boot: Getting 415 unsupported Media type

Question

I am currently writing a spring boot backend with Rest-API and trying to write data against my database. When doing a put ot post request, some strange things happen. Most of the time I get a 415 unsupported media type error, but sometimes (for some of the entities) the put/ post request works fine and the data is written correctly against the datatbase.

But in most of the cases a 415-error occurs. If I understand the error stack trace correctly, the 415 error occurs because the body of my request cannot be read. I cannot figure out why!!

I tried out serveral things:

Using consumes = MediaType.APPLICATION_JSON_VALUE, consumes = "application/json" in the @PutMapping-Annotation,
checking for loose @JsonManagedReference / @JsonBackReference,
checking for standard constructor in entites,
checking for getter/setter.
adding Content-Type: application/json to the request in e.g. Postman

But I cannot figure out, what the problem is.

Btw, I am using spring security and @JsonView-Annotation, not knowing if this is part of the problem.

Has anybody any idea???

Here is my Controller: `

@RestController
@RequestMapping(value="/source")
public class SourceController {

    private final SourceServiceImpl sourceServiceImpl;

    @Autowired
    public SourceController(SourceServiceImpl sourceServiceImpl) {
        this.sourceServiceImpl = sourceServiceImpl;
    }

   
    @PostMapping(value = "/save")
    public void saveSource(@RequestBody SourceEntity sourceEntity){
        sourceServiceImpl.save(sourceEntity);
    }

    @PutMapping(value = "/update")
    public void updateSourcee(@RequestBody SourceEntity sourceEntity) {
        sourceServiceImpl.update(sourceEntity);
    }
}

Here is my Entity:

@Entity
@Table(schema = "OWNER", name = "SOURCE")
public class SourceEntity {

    @JsonView(UntDataView.Basic.class)
    @Id
    @Column(name = "id", updatable = false, nullable = false)
    private int id;

    @OneToMany(mappedBy = "sourceEntity", cascade = CascadeType.ALL)
    private List<FirmEntity> firmEntity;

    @JsonView(UntDataView.Basic.class)
    @Column(name = "desc")
    private String desc;

    @Column(name = "create_id", insertable = false, updatable = false)
    private Integer createId;

    @ManyToOne(optional = false, fetch = FetchType.EAGER)
    @JoinColumn(name = "create_id", nullable = false)
    private UserEntity userEntityCreate;

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "create_dat", nullable = false)
    private Date createDat;

    @Column(name = "corr_id", insertable = false, updatable = false)
    private Integer corrId;

    @ManyToOne(fetch = FetchType.EAGER)
    @JoinColumn(name = "corr_id")
    private UserEntity userEntityCorr;

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "corr_dat")
    private Date corrDat;


    public SourceEntity() {
    }

    
//getter/ setter

Here is my request:
Postman
PostmanHeader

Here is the error:

What do you mean by ”in intellij”. That is not a complete request, and not reproducible. Use curl or screenshot postman etc. — Toerktumlare, Aug 08 '21 at 15:28
@Toerktumlare I added a postman screenshot. Hope, this helps. I am really desperate ... — Barbara, Aug 08 '21 at 17:54
Can you show the HTTP headers of the request you sent from Postman? — Little Santi, Aug 08 '21 at 18:03
can you please post your full debug logs, instead of just the exception. — Toerktumlare, Aug 08 '21 at 18:39
have you tried removing things one by one to see if it works then. Start out with a clean entity without annotations. — Toerktumlare, Aug 08 '21 at 18:40
At the end of the error trace says "path: /untadresse/save". Your call was supposed to execute /source/update. Do a debug setting a breakpoint in every public method of your controller, to make sure in which of them the error happens. — Little Santi, Aug 08 '21 at 21:33
@LittleSanti Sorry, copy & paste error. I tried it with severals entities/ put requests. — Barbara, Aug 09 '21 at 05:32
@Toerktumlare Nothing shows in the run console when sending the put request. This is the only error I have. I tried to debug, but did not succeed. I think the error occured while Spring tries with `@ResponseBody` to convert the return value to HTTP response body with HTTP Message converters. — Barbara, Aug 09 '21 at 05:42

Solved! I accidentally had two setters defined with different data types.
