我正在使用spring data JPA创建应用程序。在这种情况下,我试图使用注释实现服务器端验证。我在带有自定义消息的字段上添加了@NotNull
批注。我还用@valid
@RequestBody
但是问题是,当我以nAccountId
的形式传递null
时,没有得到自定义消息,即Account id can not be null
时得到的是“消息”:"Validation failed for object='accountMaintenanceSave'. Error count: 1",
。
有人可以告诉我为什么我没有收到自定义消息吗?
控制器代码
@PutMapping("/updateAccountData")
public ResponseEntity<Object> saveData(@Valid @RequestBody AccountMaintenanceSave saveObj){
return accService.saveData(saveObj);
}
AccountMaintenanceSave类
import javax.validation.constraints.NotNull;
public class AccountMaintenanceSave {
@NotNull(message="Account id can not be null")
public Integer nAccountId;
@NotNull
public String sClientAcctId;
@NotNull
public String sAcctDesc;
@NotNull
public String sLocation;
@NotNull
public Integer nDeptId;
@NotNull
public Integer nAccountCPCMappingid;
@NotNull
public Integer nInvestigatorId;
//Getter and Setter
}
RestExceptionHandler类
@ControllerAdvice
public class RestExceptionHandler {
@ExceptionHandler(Exception.class)
public ResponseEntity<Object> handleAllExceptionMethod(Exception ex, WebRequest requset) {
ExceptionMessage exceptionMessageObj = new ExceptionMessage();
exceptionMessageObj.setMessage(ex.getLocalizedMessage());
exceptionMessageObj.setError(ex.getClass().getCanonicalName());
exceptionMessageObj.setPath(((ServletWebRequest) requset).getRequest().getServletPath());
// return exceptionMessageObj;
return new ResponseEntity<>(exceptionMessageObj, new HttpHeaders(), HttpStatus.INTERNAL_SERVER_ERROR);
}
}
我不知道以前到底发生了什么,也没有得到正确的消息。现在使用相同的代码获取带有正确消息的结果
{
"message": "Validation failed for argument at index 0 in method: public org.springframework.http.ResponseEntity<java.lang.Object> com.spacestudy.controller.AccountController.saveData(com.spacestudy.model.AccountMaintenanceSave), with 1 error(s): [Field error in object 'accountMaintenanceSave' on field 'nAccountId': rejected value [null]; codes [NotNull.accountMaintenanceSave.nAccountId,NotNull.nAccountId,NotNull.java.lang.Integer,NotNull]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [accountMaintenanceSave.nAccountId,nAccountId]; arguments []; default message [nAccountId]]; default message [Account id can not be null]] ",
"error": "org.springframework.web.bind.MethodArgumentNotValidException",
"path": "/spacestudy/rockefeller/admin/account/updateAccountData"
}
在message
字段中,我只能打印[Account id can not be null]
吗?

尝试一下。
@ControllerAdvice
public class RestExceptionHandler {
@ExceptionHandler(Exception.class)
public ResponseEntity<Object> handleAllExceptionMethod(Exception ex, WebRequest requset) {
ExceptionMessage exceptionMessageObj = new ExceptionMessage();
// Handle All Field Validation Errors
if(ex instanceof MethodArgumentNotValidException) {
StringBuilder sb = new StringBuilder();
List<FieldError> fieldErrors = ((MethodArgumentNotValidException) ex).getBindingResult().getFieldErrors();
for(FieldError fieldError: fieldErrors){
sb.append(fieldError.getDefaultMessage());
sb.append(";");
}
exceptionMessageObj.setMessage(sb.toString());
}else{
exceptionMessageObj.setMessage(ex.getLocalizedMessage());
}
exceptionMessageObj.setError(ex.getClass().getCanonicalName());
exceptionMessageObj.setPath(((ServletWebRequest) requset).getRequest().getServletPath());
// return exceptionMessageObj;
return new ResponseEntity<>(exceptionMessageObj, new HttpHeaders(), HttpStatus.INTERNAL_SERVER_ERROR);
}
}

让您的 only ExceptionHandler捕获Exception.class使其成为ConstraintViolationException.class

您可以尝试以下代码吗?
import javax.validation.constraints.NotNull;
public class AccountMaintenanceSave {
@NotNull(nullable=false,message="Account id can not be null")
public Integer nAccountId;
@NotNull
public String sClientAcctId;
@NotNull
public String sAcctDesc;
@NotNull
public String sLocation;
@NotNull
public Integer nDeptId;
@NotNull
public Integer nAccountCPCMappingid;
@NotNull
public Integer nInvestigatorId;
//Getter and Setter
}
