• struts2基础---->自定义拦截器


      这一章,我们开始struts2中拦截器的学习。

    自定义拦截器

    一、增加一个自定义的拦截器为类

    package com.huhx.interceptor;
    
    import com.opensymphony.xwork2.ActionInvocation;
    import com.opensymphony.xwork2.interceptor.AbstractInterceptor;
    
    public class RegisterInterceptor extends AbstractInterceptor {
        private static final long serialVersionUID = 1L;
    
        @Override
        public String intercept(ActionInvocation invocation) throws Exception {
            System.out.println("拦截器开始运行....");
            String resultString = invocation.invoke();
            System.out.println("拦截器结束运行....");
            return resultString;
        }
    }

     二、修改struts.xml配置文件,内容如下:

    <?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd">
    <struts>
        <package name="default" namespace="/" extends="struts-default">
            <interceptors>
                <interceptor name="registerInterceptor" class="com.huhx.interceptor.RegisterInterceptor"></interceptor>
            </interceptors>
            <action name="hello" class="com.huhx.struts.HuhxAction">
                <result name="success">/huhx.jsp</result>
                <interceptor-ref name="defaultStack"></interceptor-ref>
                <interceptor-ref name="registerInterceptor"></interceptor-ref>
            </action>
        </package>
    </struts>

     三、访问地址:http://localhost:8080/StrutsTest1/hello.action,后台打印地址:

    拦截器开始运行....
    hello world.
    拦截器结束运行....
