【中文标题】解决了！ - Spring boot：获取 415 不支持的媒体类型

【英文标题】：Spring boot: Getting 415 unsupported Media type

【发布时间】：2021-10-12 12:02:10

【问题描述】：

我目前正在使用 Rest-API 编写 Spring Boot 后端，并尝试针对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，则会发生 415 错误，因为我的请求正文无法读取。我不知道为什么！

我尝试了几件事：

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

但我不知道问题是什么。

顺便说一句，我正在使用 spring security 和 @JsonView-Annotation，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

这是错误：

谢谢芭芭拉

【问题讨论】：

你的请求在哪里，是什么样子的

@Toerktumlare 抱歉，我已添加请求

“in intellij”是什么意思。这不是一个完整的请求，也无法重现。使用 curl 或截图邮递员等。

@Toerktumlare 我添加了邮递员截图。希望这可以帮助。我真的很绝望……

您能显示您从 Postman 发送的请求的 HTTP 标头吗？

【参考方案1】：

解决了！我不小心定义了两个使用不同数据类型的 setter。
