Sentinel-Dashboard-1.8持久化Nacos

一、客户端改造

1.引入pom.xml文件依赖

<!-- https://mvnrepository.com/artifact/com.alibaba.csp/sentinel-datasource-nacos -->
<dependency>
    <groupId>com.alibaba.csp</groupId>
    <artifactId>sentinel-datasource-nacos</artifactId>
    <version>2.0.0-alpha</version>
</dependency>

2.配置application.yml文件。

server:
  port: 8081

spring:
  application:
    name: sentinel-nacos-push
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/test?useSSL=false&useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8
    username: root
    password: gj001212
    type: com.alibaba.druid.pool.DruidDataSource
    
  cloud:
    nacos:
      discovery:
        server-addr: 192.168.146.1:8839
        
    sentinel:
      transport:
        dashboard: localhost:7777
        port: 8719
      eager: true
      web-context-unify: false
      datasource:
        dsl:
          nacos:
            server-addr: 192.168.146.1:8839
            data-id: ${spring.application.name}-flow-rules
            group-id: SENTINEL_GROUP
            data-type: json
            rule-type: flow

        flow-rules:
          nacos:
            server-addr: 192.168.146.1:8839
            dataId: ${spring.application.name}-flow-rules
            groupId: SENTINEL_GROUP   # 注意groupId对应Sentinel Dashboard中的定义
            data-type: json
            rule-type: flow

        degrade-rules:
          nacos:
            server-addr: 192.168.146.1:8839
            dataId: ${spring.application.name}-degrade-rules
            groupId: SENTINEL_GROUP
            data-type: json
            rule-type: degrade

        param-flow-rules:
          nacos:
            server-addr: 192.168.146.1:8839
            dataId: ${spring.application.name}-param-flow-rules
            groupId: SENTINEL_GROUP
            data-type: json
            rule-type: param-flow

        authority-rules:
          nacos:
            server-addr: 192.168.146.1:8839
            dataId: ${spring.application.name}-authority-rules
            groupId: SENTINEL_GROUP
            data-type: json
            rule-type: authority

        system-rules:
          nacos:
            server-addr: 192.168.146.1:8839
            dataId: ${spring.application.name}-system-rules
            groupId: SENTINEL_GROUP
            data-type: json
            rule-type: system

客户端改造完成

二、Sentinel-Dashboard源码改造

1.修改pom.xml中nacos的范围中【test】注释。

2.把test目录下com/alibaba/csp/sentinel/dashboard/rule下的nacos文件夹复制到main相同目录下

3.修改application.properties，增加nacos配置，修改端口

nacos.addr=localhost:8839

4.修改NacosConfig，把nacos信息交给spring容器管理

@Value("${nacos.addr}")
private String addr;

5.修改com/alibaba/csp/sentinel/dashboard/controller/v2/FlowControllerV2.java

@Autowired
@Qualifier("flowRuleDefaultProvider")
private DynamicRuleProvider<List<FlowRuleEntity>> ruleProvider;
@Autowired
@Qualifier("flowRuleDefaultPublisher")
private DynamicRulePublisher<List<FlowRuleEntity>> rulePublisher;

替换

@Autowired
@Qualifier("flowRuleNacosProvider")
private DynamicRuleProvider<List<FlowRuleEntity>> ruleProvider;
@Autowired
@Qualifier("flowRuleNacosPublisher")
private DynamicRulePublisher<List<FlowRuleEntity>> rulePublisher;

6.修改webapp/resources/app/scripts/directives/sidebar/sidebar.html
找到如下 html片段 把注释放开

注，这块有两种方式，你可以不放开注释，只需要把留空规则的方法改为
【dashboard.flow】

<li ui-sref-active="active" ng-if="!entry.isGateway">
    <a ui-sref="dashboard.flow({app: entry.app})">
        <i class="glyphicon glyphicon-filter"></i>&nbsp;&nbsp;流控规则</a>
</li>

三、测试

启动nacos和前端项目，sentinel增加流控规则


最后在nacos和sentinel修改文件，测试双向绑定是否成功
