目前，我工作的一个Web项目和使用弹簧3.0注释基地控制器。
- 我试图用拦截登录。
- 没有网址可以直接打到但从登录使用的拦截器。
我可以写一个拦截器，不会放过任何人进入网站而不给予必要的参数进行登录。 但问题是，剩余的网页也可以直接访问。
我与你我共享servlet.xml中
我也想知道为什么我要defien URL映射得到拦截工作，否则它会进入一个无限循环。
请帮我解决这个问题，如果您有任何工作示例对于这样的要求，那么也请分享。
先感谢您。
用SpringMVC-servlet.xml中

我也想对sepcific网址/ URL模式这个拦截器应用。
期待你的回复。
亲切的问候，qasibeat
这是一个相当普遍的问题。 斯科特·墨菲创造了一个很好的弹簧插件，允许基于URL的控制器上指定的拦截器。 你可以从这里下载springplugins 。
另请参阅基于注解的Spring框架控制器拦截器配置
编辑：对于3.1+版本，请参阅我的回答这个问题控制访问控制器配置基于URL模式拦截。
性能监视器拦截器实例。 它记录每次的请求接管2秒。

那么这个bean插入到你的bean名URL映射：
<bean id="handlerMapping" class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping">
<property name="interceptors">
<list>
<ref bean="performanceMonitorHandlerInterceptor" />
</list>
</property>
</bean>
