Spring 启动：获取 415 不支持的媒体类型

Question

我目前正在使用 Rest-API 编写一个 spring 引导后端，并尝试向我的数据库写入数据。在执行 put ot post 请求时，会发生一些奇怪的事情。大多数时候我收到 415 unsupported media type 错误，但有时（对于某些实体）put/post 请求工作正常并且数据正确写入数据库。

但在大多数情况下会发生 415 错误。如果我正确理解错误堆栈跟踪，则会出现 415 错误，因为无法读取我的请求正文。我不知道为什么！！

我尝试了几个东西：

在@PutMapping-Annotation中使用consumes = MediaType.APPLICATION_JSON_VALUE,consumes = "application/json",
正在检查松动 @JsonManagedReference / @JsonBackReference,
正在检查实体中的标准构造函数，
正在检查 getter/setter。
将 Content-Type: application/json 添加到请求中，例如邮递员

但是我想不通，问题是什么。

顺便说一句，我正在使用 spring 安全和 @JsonView-注释，不知道这是否是问题的一部分。

有人知道吗？？？

这是我的控制器：`

@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);
    }
}

这是我的实体：

@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

这是我的要求：
Postman
PostmanHeader

这里是错误：

已解决！我不小心用不同的数据类型定义了两个 setter。
