springMVC之拦截器

标签：style   blog   http   java   os   io   2014   cti   

有两种方法配置spring的拦截器

1. 实现接口: HandleInterceptor

public class MyInterceptor1 implements HandlerInterceptor {

	@Override
	public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object obj, Exception e) throws Exception {
		System.out.println("最后执行！！！一般用于释放资源！！");
	}

	@Override
	public void postHandle(HttpServletRequest request, HttpServletResponse response, Object obj, ModelAndView model) throws Exception {
		System.out.println("Action执行之后，生成视图之前执行！！");
	}

	@Override
	public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object obj) throws Exception {
		System.out.println("action之前执行！！！");
		return true; // 继续执行action
	}

}

public class MyInterceptor2 extends HandlerInterceptorAdapter {

	@Override
	public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
		System.out.println("MyInterceptor2.preHandle()");
		return true; // 继续执行action
	}

}

<!-- 配置自定义拦截器 -->
<mvc:interceptors>
	<bean class="com.zdp.interceptor.MyInterceptor1"></bean> <!-- 拦截所有的url！ -->
	<mvc:interceptor>
		<mvc:mapping path="/user/add" /> <!-- 只拦截添加用户 -->
		<bean class="com.zdp.interceptor.MyInterceptor2"></bean>
	</mvc:interceptor>
</mvc:interceptors>
