带有 Lombok 的 Java 对象无法在 Spring Boot 中的切点注释类中工作

分类：编程问答

如何解决带有 Lombok 的 Java 对象无法在 Spring Boot 中的切点注释类中工作

我在 Java spring 启动代码中使用了以下 DTO 对象。

ExceptionResponseDTO.java

package be.bytebrain.hrms.exception;

import java.time.LocalDateTime;

import lombok.Data;

@Data
public class ExceptionResponseDTO {
    private String message;
    private LocalDateTime dateTime;
}

我的带有切入点表达式的全局类来处理 spring-boot 控制器抛出的异常。


package be.bytebrain.hrms.exception;

import java.time.LocalDateTime;
import java.util.HashMap;
import java.util.Map;

import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.validation.FieldError;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestControllerAdvice;
import org.springframework.web.context.request.WebRequest;

@RestControllerAdvice
public class GlobalExceptionHandler {

    @ResponseStatus(HttpStatus.NOT_FOUND)
    @ExceptionHandler(NotFoundException.class)
    public ResponseEntity<Object> handleExceptions(NotFoundException exception,WebRequest webRequest) {
        var response = new ExceptionResponseDTO();

        response.setDateTime(LocalDateTime.now());
        response.setMessage(exception.getMessage());

        return new ResponseEntity<>(response,HttpStatus.NOT_FOUND);
    }

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(MethodArgumentNotValidException.class)
    public Map<String,String> handleValidationExceptions(MethodArgumentNotValidException ex) {
        Map<String,String> errors = new HashMap<>();
        ex.getBindingResult().getAllErrors().forEach((error) -> {
            String fieldName = ((FieldError) error).getField();
            String errorMessage = error.getDefaultMessage();
            errors.put(fieldName,errorMessage);
        });
        return errors;
    }
}

我在编译 spring boot 项目时的错误。

解决方法

问题已通过将 Lombok 插件路径传递给 maven 中的注释处理器部分解决。
