[英]Custom spring boot validation response
I used spring-boot validation below:我在下面使用了 spring-boot 验证:
in gradle:在 gradle 中:
implementation 'org.springframework.boot:spring-boot-starter-validation'
in request:在请求中:
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
import com.fasterxml.jackson.annotation.JsonInclude;
@JsonInclude(JsonInclude.Include.NON_EMPTY)
public class ApiTransactionRequest {
private String id;
@NotNull
private String transaction_id;
@NotNull
private String apiOperation;
@NotNull
...
When testing this case I got these infos: Spring app show this log:在测试这个案例时,我得到了这些信息:Spring app show this log:
WARN 28840 --- [nio-8080-exec-1].wsmsDefaultHandlerExceptionResolver: Resolved [org.springframework.web.bind.MethodArgumentNotValidException: Validation failed for argument [0] in public org.springframework.http.ResponseEntity
警告 28840 --- [nio-8080-exec-1].wsmsDefaultHandlerExceptionResolver:已解决 [org.springframework.web.bind.MethodArgumentNotValidException:公共 org.springframework.http.ResponseEntity 中参数 [0] 的验证失败
Http Response(spring boot validation response message) Http Response(spring boot验证响应消息)
{
"timestamp": "2022-12-05T09:58:55.011+00:00",
"status": 400,
"error": "Bad Request",
"path": "/transactions"
}
Actually I want to get the custom http response instead spring boot validation message, like this:实际上我想获取自定义 http 响应而不是 spring 启动验证消息,如下所示:
{
"date": "2022-12-05",
"status": 400.03,
"error": "Transaction id is invalid",
"message": "Transaction id is not null"
}
Any helps, tks任何帮助,谢谢
You need to use @ControllerAdvice
and make a custom exception handling.您需要使用
@ControllerAdvice
并进行自定义异常处理。 Spring should thrown MethodArgumentNotValidException
or ConstraintViolationException
- it depends do you throw the exception from the Controller or not. Spring 应该抛出
MethodArgumentNotValidException
或ConstraintViolationException
- 这取决于你是否从 Controller 抛出异常。
@ExceptionHandler(value = MethodArgumentNotValidException.class)
public ResponseEntity<MyResponse> handleException(MethodArgumentNotValidException exception) {
String customException = exception.getBindingResult().getFieldErrors().stream()
.map(x -> x.getField() + x.getDefaultMessage())
.collect(Collectors.joining(","))
return ResponseEntity.badRequest().body(new MyResponse(customException);
}
MyResponse
could have the message MyResponse
可能有消息
If you want a normal API Jason Request please use @Entity
instead:如果您想要一个普通的 API Jason 请求,请改用
@Entity
:
@Entity
public class ApiTransactionRequest {
@Id
@GeneratedValue(strategy = GenerationType.AUTO) //Add this line if you your ID will be created by the Webapp
@NotNull
private String id;
@NotNull
private String transaction_id;
@NotNull
private String apiOperation;
@NotNull
// omitted input
In your Controller you will to Something like this在您的 Controller 中,您会这样
@RestController
public class UserController {
@PostMapping("/users")
ResponseEntity<String> addUser(@Valid @RequestBody User user) {
// persisting the user
return ResponseEntity.ok("User is valid");
}
// standard constructors / other methods
}
