1 在spring-servlet.xml中进行如下配置
<mvc:interceptors> <mvc:interceptor> <mvc:mapping path="/saveObjectInstance.do"/> <mvc:mapping path="/createObjectInstance.do"/> <mvc:mapping path="/cloneObjectInstance.do"/> <bean class="com.hp.it.qdpadmin.web.interceptor.ValidationInterceptor" /> </mvc:interceptor> </mvc:interceptors>
说明:
* path 为被拦截的controller请求的url,可以配置多个
* bean class 为自定义的Interceptor
* 拦截器可以配置多个,按先后顺序进行拦截
2 定义Interceptor class 实现HandlerInterceptor
public class ValidationInterceptor implements HandlerInterceptor { private final Logger logger = Logger.getLogger(this.getClass()); @Override public void afterCompletion(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, Exception arg3) throws Exception { } @Override public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, ModelAndView arg3) throws Exception { } @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object arg2) throws Exception { //do validation return false; } }
