登录不同权限跳转不同页面

action 登录时查询用户权限，讲权限信息以集合形式存放在用户的实体类中！   

   <pre name="code" class="java">       ActionContext ac =  ActionContext.getContext();

     ActionContext ac =  ActionContext.getContext();
           Map<String, Object> ctx =ac.getSession();

           SysUserDTO uInfo=service.toSysUserDTO(user);
            //将角色信息放入用户
            List<SysRole> lst =service.findRoleByUserId(user.getId());
            uInfo.setRoleList(lst);

            ctx.put("userInfo", uInfo);

           Map<String, Object> ctx =ac.getSession();

           SysUserDTO uInfo=service.toSysUserDTO(user);
            //将角色信息放入用户
            List<SysRole> lst =service.findRoleByUserId(user.getId());
            uInfo.setRoleList(lst);

            ctx.put("userInfo", uInfo);
