大家好，欢迎来到IT知识分享网。

拦截器类

package com.csair.interceptor;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.apache.struts2.ServletActionContext;
import org.springframework.http.HttpRequest;

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

@SuppressWarnings("serial")
public class StrutsInterceptor implements Interceptor {

	public void destroy() {
		System.out.println("StrutsInterceptor  destroy");
	}
	
	public void init() {
		System.out.println("StrutsInterceptor  init");
	}

	public String intercept(ActionInvocation invocation) throws Exception {
		System.out.println("StrutsInterceptor intercept");
		HttpServletRequest request = ServletActionContext.getRequest();
		HttpSession session = request.getSession();
		String host = request.getRemoteHost();
		System.out.println("host:"+host);
		return invocation.invoke();
	}

}
