一，非Ioc（控制反转）方式

HttpServletRequest request = ServletActionContext.getRequest();HttpServletResponse response = ServletActionContext.getResponse();HttpSession session = request.getSession();

如果只是访问Session的属性（Attribute），用

//Attribute，返回值为MapActionContext.getContext().getSession();

二，Ioc（控制反转）方式

struts2 自带的拦截器

import org.apache.struts2.interceptor.SessionAware;import org.apache.struts2.interceptor.ServletRequestAware;import org.apache.struts2.interceptor.ServletResponseAware;

实现接口

public class XXXAction extends ActionSupport implements SessionAware, ServletRequestAware, ServletResponseAware { private Map<String, Object> sessionMap; @Override public void setSession(Map<String, Object> map) {  this.sessionMap = map; }  private HttpServletRequest request; @Override public void setServletRequest(HttpServletRequest request) {  this.request = request; }  private HttpServletResponse response; @Override public void setServletResponse(HttpServletResponse response) {  this.response = response; }}
