Spring Boot 全局Exception处理

一、代码如下

package com.zxguan;

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

import javax.servlet.http.HttpServletRequest;

/**
 * @author zxguan
 * @description
 * @create 2018-01-29 10:38
 */
@ControllerAdvice
public class GlobalExceptionHandler {

    @ExceptionHandler(value = NullPointerException.class)
    public void nullPointErrorHandler(HttpServletRequest req, Exception e)  {
        e.printStackTrace();
        System.out.println("------------------------    NullPointerException    --------------------------");
    }

    @ExceptionHandler(value = Exception.class)
    public void defaultErrorHandler(HttpServletRequest req, Exception e)  {
        e.printStackTrace();
        System.out.println("------------------------    Exception   --------------------------");
    }
}

二、要点

  1、@ControllerAdvice

    1)basePackages:全局异常捕获包范围

    2)basePackageClasses:扫描指定类所在包范围【通常使用一个标记类或接口,通过注解中basePackageClasses定义解析包范围】
