springmvc之默认错误页面跳转

在做一个项目的时候，为了界面美观及用户体验，我们往往会设计自己的错误跳转页面，而不是直接展示给用户一堆错误码，为此我们需要配置自己的错误跳转页面。

1、项目结构

　　


2、web.xml

　　

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
<display-name>Archetype Created Web Application</display-name>

<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- 设置dispatchservlet的匹配模式，通过把dispatchservlet映射到/，默认servlet会处理所有的请求，包括静态资源 -->
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

<!-- 字符集过滤器 -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<!--错误跳转页面-->
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/WEB-INF/views/error/404.jsp</location>
</error-page>
<error-page>
<error-code>404</error-code>
<location>/WEB-INF/views/error/404.jsp</location>
</error-page>
<error-page>
<error-code>500</error-code>
<location>/WEB-INF/views/error/500.jsp</location>
</error-page>
</web-app>

注：其实只是在原有的springmvc配置的基础上增加<error-page>标签项即可。

3、dispatcher-servlet.xml

　　

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd" default-lazy-init="true">

<!-- 通过mvc:resources设置静态资源，这样servlet就会处理这些静态资源，而不通过控制器 -->
<!-- 设置不过滤内容，比如:css,jquery,img 等资源文件 -->
<mvc:resources location="/*.html" mapping="/**.html" />
<mvc:resources location="/css/*" mapping="/css/**" />
<mvc:resources location="/js/*" mapping="/js/**" />
<mvc:resources location="/images/*" mapping="/images/**" />

<!-- 添加注解驱动 -->
<mvc:annotation-driven />
<!-- 默认扫描的包路径 -->
<context:component-scan base-package="com.*" />

<!-- mvc:view-controller可以在不需要Controller处理request的情况，转向到设置的View -->
<!-- 像下面这样设置，如果请求为/，则不通过controller，而直接解析为/index.jsp -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
</bean>

<!--  日志自定义注解拦截器 -->
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/**"/>
<bean class="com.log.SystemLogAspect"></bean>
</mvc:interceptor>
</mvc:interceptors>

</beans>

4、TestController.java

package com.controller;

import com.log.Log;
import com.remote.RemoteDemo;
import net.sf.json.JSONObject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
* Created by sunjf on 2016/6/26.
*/
@Controller
public class TestController {

@Log(desc = "log测试")
@RequestMapping(value = "test1")
public String test1(){
JSONObject jsonObject = new JSONObject();
jsonObject.put("username", "sun");
jsonObject.put("password", "123");
// String result = RemoteDemo.remoteJsonRequest("http://localhost:8080/test2?username=sun&password=123", 5000, jsonObject);
//System.out.println(result);
return "error/success1";
}

}

注：该方法跳转页面为success1.jsp，从项目结构中可以看出，我们的项目中是没有这个页面的

5、index.jsp　

<html>
<body>
<h2>Hello World!</h2>
<form action="test1" method="post" id="form1">
<input type="submit" name="submit" value="button">
</form>
</body>
</html>

6、404.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>404</title>
</head>
<body>
<h1 align="center" style="margin-top:100px;font-size: 200px">404</h1>
<h3 align="center">未能找到您访问的资源。</h3>
</body>
</html>
