最近做项目出现了前台访问出现404

控制台出现 No mapping found for HTTP request with URI [/zjic] in DispatcherServlet

web.xml如下

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" 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>zjic</display-name>  <servlet>    <servlet-name>zjic</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <load-on-startup>1</load-on-startup>  </servlet>    <servlet-mapping>    <servlet-name>zjic</servlet-name>    <url-pattern>/*</url-pattern>  </servlet-mapping>    <context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/zjic-servlet.xml</param-value></context-param>  <listener>  <listener-class>   org.springframework.web.context.ContextLoaderListener  </listener-class> </listener>    <welcome-file-list>    <welcome-file>index.jsp</welcome-file>      </welcome-file-list>    <!-- Session超时  --><session-config>  <session-timeout>-1</session-timeout></session-config></web-app>

最终找到原因把

<servlet-mapping>    <servlet-name>zjic</servlet-name>    <url-pattern>/*</url-pattern>  </servlet-mapping>

改为

<servlet-mapping>    <servlet-name>zjic</servlet-name>    <url-pattern>/</url-pattern>  </servlet-mapping>

即/* 去掉* 可以访问jsp

但是发现无法访问静态资源很郁闷

一月 25, 2016 12:57:41 上午 org.springframework.web.servlet.DispatcherServlet noHandlerFound
警告: No mapping found for HTTP request with URI [/Extjs5SSM/lib/js/app/app.js] in DispatcherServlet with name 'extjs'

警告: No mapping found for HTTP request with URI [/Extjs5SSM/lib/js/ext-5.1.0/ext-all.js] in DispatcherServlet with name 'extjs'
等等

解决了这个问题：

静态资源都在lib下面

因此在spring配置文件中加入

<!-- 静态资源访问 --><mvc:resources location="/lib/" mapping="/lib/**"/>

只需要映射webroot 下一层子目录即可

如果有多个可以写多个mvc:resources

解决了这个问题

此时.do 访问可能出现404
