No mapping found for HTTP request with URI [/zjic] in DispatcherServlet

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
