SSM 中的SpringMVC，easyUI，使用是无法加载easyUI资源

SSM框架中，jsp使用EasyUI时，无法加载EasyUI资源，致使界面无法准确显示

提示：
[org.springframework.web.servlet.PageNotFound] - No mapping found for HTTP request with URI [/SSM-2/jQuery-easyui-1.5/themes/default/easyui.css] in DispatcherServlet with name 'SpringMVC'
[org.springframework.web.servlet.PageNotFound] - No mapping found for HTTP request with URI [/SSM-2/jquery-easyui-1.5/jquery.min.js] in DispatcherServlet with name 'SpringMVC'
[org.springframework.web.servlet.PageNotFound] - No mapping found for HTTP request with URI [/SSM-2/jquery-easyui-1.5/demo/demo.css] in DispatcherServlet with name 'SpringMVC'
[org.springframework.web.servlet.PageNotFound] - No mapping found for HTTP request with URI [/SSM-2/jquery-easyui-1.5/themes/icon.css] in DispatcherServlet with name 'SpringMVC'
[org.springframework.web.servlet.PageNotFound] - No mapping found for HTTP request with URI [/SSM-2/jquery-easyui-1.5/jquery.easyui.min.js] in DispatcherServlet with name 'SpringMVC'
[org.springframework.web.servlet.PageNotFound] - No mapping found for HTTP request with URI [/SSM-2/jquery-easyui-1.5/jquery.easyui.min.js] in DispatcherServlet with name 'SpringMVC'

解决办法：

在web.xml中增加以下

        <servlet-mapping>
             <servlet-name>default</servlet-name>
             <url-pattern>*.css</url-pattern>
        </servlet-mapping>
        
        <servlet-mapping>
            <servlet-name>default</servlet-name>
            <url-pattern>*.gif</url-pattern>        
        </servlet-mapping>
            
        <servlet-mapping>
             <servlet-name>default</servlet-name>
             <url-pattern>*.jpg</url-pattern>
        </servlet-mapping>

        <servlet-mapping>
             <servlet-name>default</servlet-name>
             <url-pattern>*.png</url-pattern>
        </servlet-mapping>

        <servlet-mapping>
             <servlet-name>default</servlet-name>
             <url-pattern>*.js</url-pattern>
        </servlet-mapping>
