我在项目中的使用:
1)404找不到:
web.xml中配置:
<!-- 404错误 --> <error-page> <error-code>404</error-code> <location>/WEB-INF/view/error/404.jsp</location> </error-page>
2)其他的异常,在springMVC中.xml配置:
<!-- 将Controller抛出的异常转到特定View, 保持SiteMesh的装饰效果 --> <bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> <property name="exceptionMappings"> <props> <prop key="java.lang.Throwable">error/myException</prop> </props> </property> <!-- 默认错误页面,当找不到上面mappings中指定的异常对应视图时,使用本默认配置 --> <property name="defaultErrorView" value="error/myException"></property> <!-- 默认HTTP状态码 --> <property name="defaultStatusCode" value="500"></property> </bean>
3)对应的异常页面:
myException.jsp:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" isErrorPage="true" %> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %> <% response.setStatus(200); %> <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <link rel="stylesheet" type="text/css" href="resources/bootstrap/bootstrap.min.css"> <title><spring:message code="exception"/></title> </head> <body> <h2><spring:message code="exception"/></h2> </body> <script src="resources/js/jquery.min.js"></script> <script src="resources/bootstrap/bootstrap.min.js"></script> </html>
404.jsp:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" isErrorPage="true" %> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %> <% response.setStatus(200); %> <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <link rel="stylesheet" type="text/css" href="resources/bootstrap/bootstrap.min.css"> <title><spring:message code="code404"/></title> </head> <body> <h5><spring:message code="code404"/></h5> </body> <script src="resources/js/jquery.min.js"></script> <script src="resources/bootstrap/bootstrap.min.js"></script> </html>

Spring MVC中404 找不到页面错误可以直接使用web.xml中配置:
在<web-app/>节点内加入:
<error-page> <error-code>404</error-code> <location>/WEB-INF/views/errors/404.jsp</location> </error-page>
500的运行时错误,可以使用Spring MVC的SimpleMappingExceptionResolver配置:
<!-- 全局异常配置 --> <bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> <property name="exceptionMappings"> <props> <prop key="java.lang.Exception">errors/500</prop> <prop key="java.lang.Throwable">errors/500</prop> </props> </property> <property name="statusCodes"> <props> <prop key="errors/500">500</prop> </props> </property> <!-- 设置日志输出级别,不定义则默认不输出警告等错误日志信息 --> <property name="warnLogCategory" value="WARN"></property> <!-- 默认错误页面,当找不到上面mappings中指定的异常对应视图时,使用本默认配置 --> <property name="defaultErrorView" value="errors/500"></property> <!-- 默认HTTP状态码 --> <property name="defaultStatusCode" value="500"></property> </bean>
对应500错误的view jsp页面:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>500 Error</title> </head> <body> <% Exception ex = (Exception)request.getAttribute("exception"); %> <H2>Exception: <%= ex.getMessage()%></H2> <P/> <% ex.printStackTrace(new java.io.PrintWriter(out)); %> </body> </html>
测试:
另外,也可以使用继承HandlerExceptionResolver来处理500的错误。
