springboot统一异常处理HandlerExceptionResolver
-
实现HandlerExceptionResolver
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerExceptionResolver;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
//全局异常
@Component
public class GlobleException implements HandlerExceptionResolver {
@Override
public ModelAndView resolveException(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) {
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("500");
modelAndView.addObject("message",e.getMessage());
return modelAndView;
}
}

开发一个500.jsp的页面
程序中一旦出现异常就会跳转到500.jsp页面
<%@page contentType="text/html; UTF-8" pageEncoding="UTF-8" isELIgnored="false" %>
<!doctype html>
<html lang="en">
