Struts2获取Servlet API中的一些对象

1.非IoC方式

HttpServletRequest request = ServletActionContext.getRequest();

HttpServletResponse response = ServletActionContext.getResponse();

HttpSession session = ServletActionContext.getRequest().getSession();

HttpSession session = (HttpSession) ActionContext.getContext().get(

        ServletActionContext.SESSION);

Map map = (Map) ActionContext.getContext().getSession(); 

2.IoC方式

使用SessionAware、ServletRequestAware、ServletResponseAware接口。

package com.action;

import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.interceptor.ServletRequestAware;

import org.apache.struts2.interceptor.ServletResponseAware;

import org.apache.struts2.interceptor.SessionAware;

import com.opensymphony.xwork2.ActionSupport;

import com.pojo.User;

public class LoginAction2 extends ActionSupport implements SessionAware,

        ServletRequestAware, ServletResponseAware {

    HttpServletRequest request;

    HttpServletResponse response;

    Map session;

    public void setSession(Map session) {

        this.session =session;

    }

    public void setServletRequest(HttpServletRequest request) {

        this.request = request;

    }

    public void setServletResponse(HttpServletResponse response) {

        this.response = response;

    }

    public String execute() throws Exception {

        return SUCCESS;

    }

}
