springboot通过aop处理抛出的异常exception

写一个配置类拦截所有Exception

import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;

@ControllerAdvice
public class ExceptionCatch {

    @ExceptionHandler(Exception.class)
    @ResponseBody
    public ResponseResult ExceptionHandle(Exception e) {
        e.printStackTrace();
        return ResponseResult.error("错误信息:"+e.getMessage());  // ResponseResult为我们自己封闭的实体类
    }
}

 

拦截指定的异常用以下的方法（自定义的异常）

@ExceptionHandler(MyException.class)
@ResponseBody
public ResponseResult ExceptionHandle2(MyException e) {
    final ResponseResult responseResult = new ResponseResult();
    responseResult.setCode(e.getStatus().toString());
    responseResult.setMessage(e.getMessage());
    return responseResult;
}
