请问高手，struts2中action中取不到session的值。
代码如下：
java代码如下：
public class LoginAction extends BaseAdminAction {
getRequest().getSession().setAttribute(SystemUtil.USERINFO, user);
ActionContext.getContext().getSession().put("dishesPM","dishesPM");
System.out.println("================LoginAction.checkLogin() USERINFO/dishesPM set=============="+getRequest().getSession().getId());
return ajax(Status.success, "登录成功");
}
public class IndexAction extends BaseAdminAction {
private static final long serialVersionUID = 12L;
public String index(){
String test = (String)getRequest().getSession().getAttribute("dishesPM");
//System.out.println(test+"===========IndexAction.list() dishesPM get================="+getRequest().getSession().getId());
test = (String)ActionContext.getContext().getSession().get("dishesPM");
System.out.println(test+"===========IndexAction.list() dishesPM get================="+getRequest().getSession().getId());
return "index";
}
}
基类写了几个公共的方法如下：
public class BaseAdminAction extends ActionSupport {// 获取Request
// 获取Request
protected HttpServletRequest getRequest() {
return ServletActionContext.getRequest();
}
// 获取Response
protected HttpServletResponse getResponse() {
return ServletActionContext.getResponse();
}
// 获取ServletContext
protected ServletContext getServletContext() {
return ServletActionContext.getServletContext();
}
// 获取Attribute
protected Object getAttribute(String name) {
return ServletActionContext.getRequest().getAttribute(name);
}
// 设置Attribute
protected void setAttribute(String name, Object value) {
ServletActionContext.getRequest().setAttribute(name, value);
}
// 获取Parameter
protected String getParameter(String name) {
return ServletActionContext.getRequest().getParameter(name);
}
// 获取Parameter数组
protected String[] getParameterValues(String name) {
return ServletActionContext.getRequest().getParameterValues(name);
}
// 获取Session
protected Object getSession(String name) {
ActionContext actionContext = ActionContext.getContext();
Map<String, Object> session = actionContext.getSession();
return session.get(name);
}
// 设置Session
protected void setSession(String name, Object value) {
ActionContext actionContext = ActionContext.getContext();
Map<String, Object> session = actionContext.getSession();
session.put(name, value);
}
// 移除Session
protected void removeSession(String name) {
ActionContext actionContext = ActionContext.getContext();
Map<String, Object> session = actionContext.getSession();
session.remove(name);
}
}

以上是主要的代码。
现在loginaction 转到的main.jsp可以取到session的值，但main.jsp进入到indexAction.action中就取不到session的值。所有的action类都一样，经过页面进来的action都不能取到session的值。
