Spring Boot 全局异常捕获

import javax.servlet.http.HttpServletRequest;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;

/*1,新建异常捕获类
 *2,类上添加注解@ControllerAdvice
 *3,在Class里面添加方法
 *4，方法上添加注解@ExceptionHandler(Exception.class)用来拦截相应的异常信息
 *5,如果返回的是View,方法返回值是ModelAndView
 *6,如果返回的是String或者Json数据，则需要加@ResponseBody注解
