最近在使用SSM整合一个通用的后台管理系统,记录一下自己的整合过程,方便以后查阅,今天我们来说一下web.xml,该配置文件通常放置在WebRoot/WEB-INF文件夹下面,该配置文件会随着自己的整合不断修改。配置文件如下:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

<!--开始定义默认启动页-->

<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<!--结束定义默认启动页-->
<!--开始配置异常处理 -->
<error-page>
<error-code>404</error-code>
<location>/404.html</location>
</error-page>
<error-page>
<error-code>505</error-code>

</error-page>
<error-page>
<exception-type>java.lang.NullPointerException</exception-type>
<location>/error.html</location>
</error-page>
<!--结束配置异常处理 -->
<!-- 开始配置spring核心监听器,默认会以 /WEB-INF/spring.xml作为配置文件 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- contextConfigLocation参数用来指定Spring的配置文件-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring.xml</param-value>
</context-param>
<!-- 结束配置spring核心监听器-->
<!--开始定义Spring MVC的前端控制器,默认路径是/WEB-INF/{servlet-name}-servlet.xml,可以修改名称及路径-->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/springmvc-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<!-- 此处可以可以配置成*.do,对应struts的后缀习惯 -->
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--结束定义Spring MVC的前端控制器 -->
<!-- 解决工程编码过滤器开始 -->
<filter>
<filter-name>characterEncodingFilter</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>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 解决工程编码过滤器结束日 -->
</web-app>
