Package cn.mapway.ui.server

Class CheckUserServlet<T>

  • All Implemented Interfaces:
    com.google.gwt.user.server.rpc.SerializationPolicyProvider, Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig
    public abstract class CheckUserServlet<T>
extends com.google.gwt.user.server.rpc.RemoteServiceServlet
    CheckUserServlet

    Session 不会存放用户信息 API 调用 利用TOKEN去查找 用户信息 GWTRPC 和API共享TOKEN 登录后 返回TOKEN，客户端将TOKEN保存 每次请求都添加到HTTP头中 GWT RPC 从头中读取TOKEN信息,利用TOKEN信息从数据库中获取用户信息存放到Request中,也就是requestUser
