刷新浏览器或者点解Consumer页面的刷新按钮，有几率丢失客户端数据

刷新页面或者点击刷新按钮多次后，如下图客户端数据丢失：

dashboard日志中报错如下：

可见多次刷新后，dashboard无视页面中disable proxy的设置，依然试图通过proxy （默认设置127.0.0.1:8080）获取消费者信息；这应该是一个bug；

目前解决此问题的方法是：

1. 手动点击页面中 Enable Proxy 按钮2次（重置disable状态）
2. 点击REFRESH按钮，消费者信息恢复正常

[zergduan]

这个bug 100%触发的方法：

1. 启动dashboard浏览器，第一次进入Consumer页面，消费者信息正常显示
2. 刷新浏览器，此时消费者信息正常
3. 点击页面中的REFES按钮，触发bug，消费者信息丢失

恢复消费者信息方法：

1. 点击两次Enable Proxy按钮，最终让Enable Proxy重置为disable状态
2. 点击REFESH按钮，消费者信息恢复正常

[zergduan]

此BUG的原因有两点：

1. 浏览器刷新后，Consumer页面的Select Proxy的值从空变为了127.0.0.1:8080(默认值）
2. Consumer页面的REFRESH按钮不遵循Enable Proxy的设置，即：即使Enable Proxy设置为Disable，REFRESH按钮依然会使用Select Proxy的值获取Consumer信息

[zergduan]

临时解决方案，编译前将proxy的地址默认值设置为空，即修改 src/main/resources/application.yml

proxyAddrs:
  - 127.0.0.1:8080
