Struts2 配置过滤器

Struts2 配置过滤器,他跟Result是一个地位，也是在action里面可以配置的

<struts>    <package name="test" extends="struts-default">        <interceptors>这是自定义的过滤器            <interceptor name="myInter" class="com.interceptor.myInterceptor"></interceptor>            <interceptor-stack name="defaultStack">                <interceptor-ref name="token" />                <interceptor-ref name="defaultStack"></interceptor-ref>将自定的过滤器添加到栈里面，不将这个加到栈里面，会出现前段的参数传递不过来                <interceptor-ref name="myInter"></interceptor-ref>            </interceptor-stack><!-- 这个是我自己定义一个栈，将默认的栈放到我自己定义的栈中            <interceptor-stack name="myStack">                <interceptor-ref name="token" />                <interceptor-ref name="defaultStack" />                <interceptor-ref name="myInter" />            </interceptor-stack> -->        </interceptors>    </package></struts>  

接受请求的ACtion类

package com.act;import javax.interceptor.Interceptor;import org.apache.struts2.convention.annotation.Action;import org.apache.struts2.convention.annotation.InterceptorRef;import org.apache.struts2.convention.annotation.ParentPackage;import org.apache.struts2.convention.annotation.Result;import com.opensymphony.xwork2.ActionSupport;@ParentPackage("test")public class FilterTestAct extends ActionSupport{    private String msg;    private Integer id;    private String money;    private String msg1;    @Override//我是用的是默认的defaultStack这个所以我注释了/*,interceptorRefs={@InterceptorRef("myStack")}*/这句代码    @Action(value="test",results={@Result(location="index.jsp")}/*,interceptorRefs={@InterceptorRef("myStack")}*/)    public String execute() throws Exception {        // TODO Auto-generated method stub        msg="Action+done!"+id;        return SUCCESS;    }    @Action(value="pay",results={@Result(location="index.jsp"),@Result(name="invalid.token" ,location="err.jsp")}/*,interceptorRefs={@InterceptorRef("myStack")}*/)    public String pay(){        msg1=money;        return SUCCESS;    }    public String getMsg() {        return msg;    }    public void setMsg(String msg) {        this.msg = msg;    }    public Integer getId() {        return id;    }    public void setId(Integer id) {        this.id = id;    }    public String getMoney() {        return money;    }    public void setMoney(String money) {        this.money = money;    }    public String getMsg1() {        return msg1;    }    public void setMsg1(String msg1) {        this.msg1 = msg1;    }}

package com.interceptor;import java.util.Random;import com.opensymphony.xwork2.ActionInvocation;import com.opensymphony.xwork2.interceptor.AbstractInterceptor;public class myInterceptor extends AbstractInterceptor{private Random random=new Random();private int ss=5000;    @Override    public String intercept(ActionInvocation arg0) throws Exception {            long beginTimer=System.currentTimeMillis();        Thread.currentThread().sleep(random.nextInt(5)*1000);        //拦截通过        String relcode=arg0.invoke();        System.out.println("处理时间"+(System.currentTimeMillis()-beginTimer));//用来判断拦截是否给通过        return relcode;}}

然后是传到过滤器里面：
在invoke上面的打印会在action之前处理
在invoke下面的打印会在action之后处理
