- - Sentinel-Dashboard-1.8 Persistence Nacos

1. Client modification

1.Introduce pom.xml file dependency

<!-- 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. Configure the application.yml file.

Client transformation completed

2. Sentinel-Dashboard source code modification

1. Modify the [test] comment in the scope of nacos in pom.xml .
Insert image description here
2. Copy the nacos folder under com/alibaba/csp/sentinel/dashboard/rule in the test directory to the same directory as main

3. Modify application.properties, add nacos configuration, and modify the port

nacos.addr=localhost:8839

4. Modify NacosConfig and hand over nacos information to spring container management

@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;

replace

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

6. Modify webapp/resources/app/scripts/directives/sidebar/sidebar.html
to find the following html fragment and release the comments

Note, there are two ways to do this. You don’t need to leave comments, you just need to change the method of leaving blank rules to
[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>

3. Test

Start nacos and front-end projects, add flow control rules

in sentinel, and finally modify the files in nacos and sentinel to test whether the two-way binding is successful.
