struts2自定义拦截器及其配置（备份）

代码：

package com.web.action;

import java.util.Date;

import java.util.Map;

import com.opensymphony.xwork2.ActionInvocation;

import com.opensymphony.xwork2.interceptor.Interceptor;

public class HistoryLogStack implements Interceptor {

/**

*

*/

private static final long serialVersionUID = -1385902554116735266L;

public void destroy() {

System.out.println("日志拦截器销毁...");

}

public void init() {

System.out.println("日志拦截器初始化...");

}

public String intercept(ActionInvocation invocation) throws Exception {

System.out.println("日志拦截器已经开始启动..");

String result = invocation.invoke();

String actionName= invocation.getAction().getClass().toString();

String method = invocation.getProxy().getMethod();

final Map <String,Object> parameters = invocation.getInvocationContext().getParameters();

System.out.println("Action: " + actionName + ", Method: " + method);

System.out.println("拦截的参数为：");

for (Map.Entry<String, Object> map : parameters.entrySet()) {

System.out.println(map.getKey() + "--" + map.getValue());

}

if(method != null && method.startsWith("save")){

System.out.println("Execute save method..." + new Date());

}

return result;

}

}

配置：

<interceptors>

<interceptor name="historyLog" class="com.web.action.HistoryLogStack" />

<interceptor-stack name="myDefStack">

<interceptor-ref name="historyLog" />

<interceptor-ref name="paramsPrepareParamsStack" />

</interceptor-stack>

</interceptors>

<default-interceptor-ref name="myDefStack" />
