转换的对象如下：
public class Session implements Serializable{
/**
*
*/
private static final long serialVersionUID = -3623518883696273400L;
/**
* 在会话对象中保存的内容
*/
private Map<Object, Object> sessionContent;
public void setAttribute(Object k, Object v) {
if (k != null && v != null) {
this.sessionContent.put(k, v);
}
}
}
我先将这个对象保存在另一台服务器的内存中，后面在需要用到这个对象的时候，通过http取回来，代码如下：
/**
*
* Description : 通过sessionId获得session对象
*
* @author : ChenBin
* @date : 2019年9月7日 下午2:56:48
*/
public static Session get(String sessionId) {
Map<String, Object> params = new HashMap<>();
params.put("sessionId", sessionId);
String json = Http.post(GET, params, Config.CACHE_TIMEOUT);
return Json.fromJson(Session.class, json);
}
在另外一个地方调用了这个 get(String sessionId) 方法，代码如下：
...
Session session = SC.get(sessionId);
if (session == null)
return false;
BaseUser user = (BaseUser) session.getAttribute(AK.S_USER);// 此处报错
if (user == null)
return false;
return true;
...
报错内容如下：
