对spring中的Controller做拦截

spring中对自己的Controller有专门的拦截器，如果你用spring的AOP进行拦截的话，是不能拦截的。下面是利用spring的HandlerInterceptorAdapter类来做的拦截。
1.拦截器的代码：

public class BlockControllAdvice extends HandlerInterceptorAdapter  {
    private static final Logger log = Logger.getLogger(BlockControllAdvice.class);

    /** 权限验证方法，
     *
     * @param request,response,handler
     * @return boolen
     * @auther kaungyujian
     */
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

        log.debug("into controller advice........");

        MultiActionController maControl = (MultiActionController) handler;
        ParameterMethodNameResolver pmrResolver = (ParameterMethodNameResolver) maControl.getMethodNameResolver();
        String methodName = pmrResolver.getHandlerMethodName(request);
        String className = handler.getClass().getName();
        String path = request.getRequestURI();   //获得请求的路径    }
}

2.配置拦截器：

 <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="interceptors">
            <list>
                <ref bean="beforeBlock"/>
            </list>
        </property>
        <property name="mappings">
            <props>
                <prop key="/test.do">testController</prop>
            </props>
        </property>
    </bean>

    <bean id="beforeBlock" class="com.juraglobal.softguard.common.web.action.BlockControllAdvice"/>

3.拦截器如果要中断运行，这里的方法只能抛出异常：

 <bean id="exception" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
        <property name="exceptionMappings">
            <props>
                <prop key="com.juraglobal.softguard.common.web.action.RightPassException">noRight</prop>
            </props>
        </property>
    </bean>
