    <!--启用 MVC注解(@Controller,@RequestMapping)实现URL映射-->

    <bean id="viewResolver"

程序启动后日志：
23-Jul-2016 14:05:35.050 WARNING [http-apr-8080-exec-2] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/dps/WEB-INF/views/index.jsp] in DispatcherServlet with name 'dps'
23-Jul-2016 14:05:37.841 WARNING [http-apr-8080-exec-7] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/dps/WEB-INF/views/index.jsp] in DispatcherServlet with name 'dps'

web根目录变成了/dps/WEB-INF而不是/WEB-INF ?????????

解决方案

在web.xml中把url-pattern改成/就行了

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