[英]How to fix 'HttpMessageNotReadableException' and 'SocketTimeOutException' occured in spring boot
[英]Spring Boot HttpMessageNotReadableException
我有这个课程来代表一个用户:
@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonIgnoreProperties(ignoreUnknown = true)
@Getter
@Setter
public class UserDto implements Serializable {
private Long id;
private String username;
private String email;
private String password;
private Collection<? extends GrantedAuthority> roles;
public UserDto() {
}
}
}
我正在尝试做的是让Spring将下面控制器的@RequestBody映射到UserDto:
public class AuthController {
@Autowired
private UserService userService;
@Autowired
private AuthService authService;
@RequestMapping(value = "signup", method = RequestMethod.POST)
public ResponseEntity<?> addUser(@RequestBody UserDto userDto) throws Exception {
UserDto existingUserDto;
try {
existingUserDto = userService.save(userDto);
} catch (Exception e) {
return new ResponseEntity<>(e.getMessage(), HttpStatus.INTERNAL_SERVER_ERROR);
}
return new ResponseEntity<>(existingUserDto, HttpStatus.CREATED);
}
}
但是,当我尝试发送Post请求时,我从Spring得到以下错误:
Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Could not read document: Unrecognized token 'username': was expecting ('true', 'false' or 'null')
at [Source: java.io.PushbackInputStream@2c477da6; line: 1, column: 10]; nested exception is com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'username': was expecting ('true', 'false' or 'null')
at [Source: java.io.PushbackInputStream@2c477da6; line: 1, column: 10]
我试图做的是声明一个自定义MappingJackson2HttpMessageConverter,但没有得到任何不同的结果
@Bean
public MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter() {
MappingJackson2HttpMessageConverter jsonConverter = new MappingJackson2HttpMessageConverter();
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
jsonConverter.setObjectMapper(objectMapper);
return jsonConverter;
}
这是我正在执行的请求的屏幕(Content-Type:application / json):
你有什么主意吗?
您能否将控制器方法@RequestMapping
更改为以下内容。
@RequestMapping(value = "", method = RequestMethod.POST, produces = { MediaType.APPLICATION_JSON_UTF8_VALUE })
另外,您无需添加自定义MappingJackson2HttpMessageConverter
即可完成此操作,还请确保在控制器中标注了正确的请求映射。
@Controller
@RequestMapping("/api/users")
还要在模型类中删除以下注释。 将getter和setter添加到所有属性,同时保留默认构造函数。
@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonIgnoreProperties(ignoreUnknown = true)
@Getter
@Setter
希望这可以帮助。 编码愉快!
