    public void testQueryAll() {
        for (int i = 0; i < 500; i++) {
                List<User> list = this.userService.queryAll();
                for (User user : list) {
                    System.out.println(user);
                }

                try {
                    Thread.sleep(i * 10);
                } catch (InterruptedException e) {
                    e.printStackTrace();

管理

dubbo提供了一套在线管理整个服务的功能，管理控制台为阿里内部裁剪版本，开源部分主要包含：路由规则，动态配置，服务降级，访问控制，权重调整，负载均衡，等管理功能。

安装

将dubbo-admin-2.5.3.war部署到tomcat的webapps目录下：
删掉其他的文件夹，留下ROOT文件夹。

把ROOT文件夹下的也全部删掉。

启动可能会发现错误如下：

原因是：jdk版本太高，jdk8, dubbo默认用的spring版本比较旧，冲突导致。
解决的办法其实很简单，直接升级dubbo-admin即可了。
