首先因为在web.xml里面配置了
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
导致所有的连接都会经过DispatcherServlet,会过滤掉css、js等样式,导致页面无法渲染成功
因此需要在springmvc配置文件中放行静态资源
<!--过滤静态资源-->
<mvc:resources mapping="/common/**" location="/common/"/>
<mvc:resources mapping="/css/**" location="/css/"/>
<mvc:resources mapping="/images/**" location="/images/"/>
<mvc:resources mapping="/js/**" location="/js/"/>
<mvc:resources mapping="/json/**" location="/json/"/>
<mvc:resources mapping="/jsplug/**" location="/jsplug/"/>
如果配置了拦截器,在拦截器中放行静态资源
<!--配置拦截器-->
<mvc:interceptors>
<mvc:interceptor>
<!-- 拦截所有mvc控制器 -->
<mvc:mapping path="/**"/>
<!-- mvc:exclude-mapping是另外一种拦截,它可以在你后来的测试中对某个页面进行不拦截,这样就不用在
LoginInterceptor的preHandler方法里面获取不拦截的请求uri地址了(优选) -->
<!--以下资源不进行拦截-->
<mvc:exclude-mapping path="/user/toLogin" />
<mvc:exclude-mapping path="/user/login" />
<mvc:exclude-mapping path="/common/**"/>
<mvc:exclude-mapping path="/css/**"/>
<mvc:exclude-mapping path="/images/**"/>
<mvc:exclude-mapping path="/js/**"/>
<mvc:exclude-mapping path="/json/**"/>
<mvc:exclude-mapping path="/jsplug/**"/>
<bean class="com.lintrondata.fyds.interceptor.LoginInterceptor"></bean>
</mvc:interceptor>
</mvc:interceptors>
