具有MultiPartFile属性的Restful POST API DTO的Spring Boot测试

Question

我有一个Spring Boot应用程序，它有一个RestController，使用以下POST方法：

@PostMapping(path = "/add", headers = {"content-type=multipart/form-data; charset=utf-8"})
    public ResponseEntity<UserWebDTO> addUser(@RequestHeader HttpHeaders headers, @ModelAttribute UserAddDTO userAddDTO) throws Exception {
        return new ResponseEntity<>(userService.addUser(userAddDTO), HttpStatus.CREATED);
    }

public class UserAddDTO {

private String first_name;

private String last_name;

private String country_code;

private String phone_number;

private GenderEnum gender;

private String birthdate;

private MultipartFile avatar;

private String email;

com.fasterxml.jackson.databind.exc.InvalidDefinitionException：找不到类java.io.ByteArrayInputStream的序列化程序，也找不到创建BeanSerializer的属性（为避免异常，禁用SerializationFeature.fail_on_empty_Beans）（通过引用链:com.user.basic.authentication.dtos.UserAddDto[“avatar”]->org.springframework.mock.web.mockMultiPartFile[“InputStream”])

感谢任何帮助。

谢谢！

我相信您需要实现可序列化的

public class UserAddDTO implements Serializable {
private static final long serialVersionUID = 1L;

private String first_name;

private String last_name;

private String country_code;

private String phone_number;

private GenderEnum gender;

private String birthdate;

private MultipartFile avatar;

private String email;

}
