前言
我不知道你有没有看上一篇sentinel-apollo拉模式,相信看过的同学对于那么复杂结构的数据很头疼,起码我们运维小哥明确表态了不会用的,那么有没有通过在sentinel-dashboard直接修改然后同步到apollo上呢,也就是推模式.我也是经过了一番痛苦折腾后才知道有.改起来也不是很复杂.

sentinel-dashboard 修改步骤
修改好的代码地址: https://github.com/zhaoyunxing92/sentinel-dashboard-apollo
如果你对需改代码不感兴趣可以直接跳过到整合部分,这个代码你需要编译一份可以运行就可以了
如果你看过sentinel的源码就会发现其实人家已经实现了一小部分推模式的代码
前端
如果你很熟悉mvc并且做过mvc模式的开发那么看前端angular代码我敢保证你仅仅需要半个小时就能掌握它甚至更少时间
app.js文件 resources/app/scripts/app.js
.state('dashboard.flow', {
templateUrl: 'app/views/flow_v2.html',
url: '/v2/flow/:app', // 这对应的地址栏的url
controller: 'FlowControllerV2', // 这个说明用的那个控制器,你只需要找到对应的文件就可以
resolve: {
loadMyFiles: ['$ocLazyLoad', function ($ocLazyLoad) {
return $ocLazyLoad.load({
name: 'sentinelDashboardApp',
files: [
'app/scripts/controllers/flow_v2.js' // 打开这个文件
]
});
}]
}
})
flow_v2.js resources/app/scripts/controllers/flow_v2.js
这个时候发现注入了一个 FlowServiceV2服务,可以打开FlowServiceV2服务的文件了
app.controller('FlowControllerV2', ['$scope', '$stateParams', 'FlowServiceV2', 'ngDialog',
'MachineService',
function ($scope, $stateParams, FlowService, ngDialog,
MachineService) {
$scope.app = $stateParams.app;
$scope.rulesPageConfig = {
pageSize: 10,
currentPageIndex: 1,
totalPage: 1,
totalCount: 0,
};
FlowServiceV2 resources/app/scripts/services/flow_service_v2.js
打开后你会发现里面都是跟后端通信的逻辑是不是很简单.app.js > controller > service 三步骤
app.service('FlowServiceV2', ['$http', function ($http) {
this.queryMachineRules = function (app, ip, port) {
var param = {
app: app,
ip: ip,
port: port
};
return $http({
url: '/v2/flow/rules',
params: param,
method: 'GET'
});
};
后端
后端部分由于我修改的太多不可能都写出来,我就总结下我在修改的时候遇到的问题吧
数据push到了apollo,sentinel-dashboard界面也能看到数据,但是配置的规则就是不生效
这个问题是由于我们给apollo注入了不必要的属性,可以参考issues
伪代码 @JSONField(serialize = false)后数据就不会到apollo了
public class FlowRuleEntity implements RuleEntity {
@JSONField(serialize = false)
private Long id;
@JSONField(serialize = false)
private String app;
@JSONField(serialize = false)
private String ip;
@JSONField(serialize = false)
private Integer port;
}
整合流程
pom.xml 如果看过拉模式可以跳过

application.yml
注意里面的key不用随意修改,除非你很清楚你在干什么
