Struts 2 中对 request、response、session的获取

 

下面是网络流行的两种方式，推荐使用IOC这种。

 

package com.alpha.test;import java.util.Map;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.struts2.ServletActionContext;import org.apache.struts2.interceptor.ServletRequestAware;import org.apache.struts2.interceptor.ServletResponseAware;import org.apache.struts2.interceptor.SessionAware;import com.opensymphony.xwork2.ActionContext;import com.opensymphony.xwork2.ActionSupport;public class BaseAction extends ActionSupport implements SessionAware,ServletRequestAware, ServletResponseAware {private static final long serialVersionUID = 1L;// not IOCActionContext context = ActionContext.getContext();HttpServletRequest request = (HttpServletRequest) context.get(ServletActionContext.HTTP_REQUEST);HttpServletResponse response = (HttpServletResponse) context.get(ServletActionContext.HTTP_RESPONSE);@SuppressWarnings("unchecked")Map session = context.getSession();//Map session = (Map) context.get(ActionContext.SESSION); // IOC @SuppressWarnings("unchecked")public void setSession(Map session) {this.session = session;}public void setServletRequest(HttpServletRequest request) {this.request = request;}public void setServletResponse(HttpServletResponse response) {this.response = response;}}
