在spring.xml中加入

<!-- 配置攔截器 -->
<mvc:interceptors>
<mvc:interceptor>
<!-- 匹配的是url路徑， 如果不配置或/**,將攔截所有的Controller -->
<mvc:mapping path="/**" />
<bean class="cn.yld.webchatapp.service.InterceptorService">
<property name="excludedUrls">
<list>
<value>/test1</value>
</list>
</property>
</bean>
</mvc:interceptor>
<!-- 當設定多個攔截器時，先按順序呼叫preHandle方法，然後逆序呼叫每個攔截器的postHandle和afterCompletion方法 -->
</mvc:interceptors>

excludedUrls是可以訪問的資源路徑
