如何在休息服务中使用带有@RequestBody的MULTIPART_FORM_DATA发送帖子

Question

我想发送@RequestBody作为邮政请求到宁静的服务。在@RequestBody我有id，title，aboutMe和image file。我设置produces = MediaType.MULTIPART_FORM_DATA_VALUEbut当我检查休息我得到错误，说406不能接受。我怎么解决它？

我的控制器：

@RequestMapping(value = "aboutMe", method = RequestMethod.POST, produces = MediaType.MULTIPART_FORM_DATA_VALUE)
    public String saveAboutMe(@RequestBody Author author) {
        authorService.saveAboutMe(author);
        return "saved";
    }

和实体

@Entity
@Table(name = "author")
public class Author {
    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "HIBERNATE_SEQUENCE")
    @SequenceGenerator(name = "HIBERNATE_SEQUENCE", sequenceName = "HIBERNATE_SEQUENCE", allocationSize = 1, initialValue = 1)
    private int id;

    @Column(name = "title")
    private String title;

    @JsonFormat(pattern = "yyyy-MM-dd  HH:mm")
    @Column(name = "dateOfAuthor")
    @Temporal(TemporalType.TIMESTAMP)
    private Date modifiedTime;

    @Column(name = "aboutMe", length = 10000)
    private String aboutMe;

    @Column(name = "image")
    @Lob
    private Blob image;
}

我从休息error得到的截图

你无法传递@RequestBody和Blob对象，图像应该是MultipartFile对象。所以对于工作代码：

1）将SessionFactory注入控制器类或要将Mulitpart转换为Blob对象的任何类中

@Autowired
private SessionFactory sessionFactory;

2）Controller类的更改：

@RequestMapping(value = "aboutMe", method = RequestMethod.POST)
public String saveAboutMe(Author author,@RequestPart("image") MultipartFile imageFile) {
    //Convert Multipart file into BLOB
    try {
        Blob image = Hibernate.getLobCreator(sessionFactory.getCurrentSession()).createBlob(authorImage.getInputStream(),authorImage.getSize());
        author.setImage(image);
    } catch (HibernateException | IOException  exception) {
        log.error(exception.getMessage(),exception);
    }

    authorService.saveAboutMe(author);
    return "saved";
}
