為struts2中自己實現webwork2中的AroundInterceptor攔截器

package com.yanek.util;

import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.Interceptor;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

public abstract class AroundInterceptor
implements Interceptor
{
protected transient Log log;

public AroundInterceptor()
{
this.log = LogFactory.getLog(super.getClass()); }

public void destroy() {
}

public void init() {
}

public String intercept(ActionInvocation invocation) throws Exception {
String result = null;

    before(invocation);
    result = invocation.invoke();
    after(invocation, result);

return result;
}

protected abstract void after(ActionInvocation paramActionInvocation, String paramString)
throws Exception;

protected abstract void before(ActionInvocation paramActionInvocation)
throws Exception;
}

實現它:可以處理action執行前,執行後的攔截處理
