Spring 4 Rest with Hibernate Validator 不显示内联消息
Spring 4 Rest with Hibernate Validator does not display inline message
我有一个示例 Spring Rest 服务项目，我试图在其中实现休眠验证程序。我现在被困在向其余呼叫者显示错误消息。我有 Spring Rest 的代码，下面列出了 DTO
控制器
import javax.validation.Valid;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.project.home.rest.SampleDTO;
@RestController(value = "/validator")
public class ValidatorController {
@RequestMapping(method = RequestMethod.POST)
public String validate(@Valid @RequestBody SampleDTO sampleDTO) {
return "Hello User Validator Serivce in play";
}
}
示例DTO
public class SampleDTO {
@NotNull
@Min(value = 18, message = "ID must be greater than 18 characters long")
@Max(value = 100, message = "ID must be less than 100 Characters Long")
private int id;
@NotNull(message = "Name is Compulsory")
private String name;
@Email(message = "Email address not Valid")
@NotEmpty(message = "Email address can not be null")
private String email;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
当通过 Rest Client 访问 Rest Service 时，我确实看到了 400 bad request 错误，但错误消息并未显示。
我在 Tomcat 控制台中得到的错误是

我也尝试过使用 BindingResult 的替代版本，但在那种情况下我得到 500 Internal server error
修改后的代码
Controller
@RestController(value = "/validator")
public class ValidatorController {
@RequestMapping(method = RequestMethod.POST)
public String validate(@Valid @RequestBody SampleDTO sampleDTO, BindingResult bindingResult) {
if(bindingResult.hasErrors()){
throw new MethodArgumentNotValidException();
}

@ControllerAdvice
public class CentralControllerHandler {

public ResponseEntity<String> handleMethodArgumentException(String message){

如果验证失败，您的 RequestMapping 应该抛出一个 MethodArgumentNotValidException。
@RequestMapping(method = RequestMethod.POST)
public ResponseEntity validate(@Valid @RequestBody SampleDTO sampleDTO) {
//this should throw a MethodArgumentNotValidException if the validation fails
return new ResponseEntity<>("Validation successful", HttpStatus.OK)
}
像这样创建异常处理程序并return向调用者发送验证消息。
