sentinel持久化配置至nacos

持久化至nacos需改造sentinel控制台

sentinel版本1.8.3

1、修改pom文件，去除sentinel 连接nacos jar包限制

        
            com.alibaba.csp
            sentinel-datasource-nacos
            
        

2、application.properties 文件新增配置(也在NacosConfig.nacosConfigService()中配置)

nacos.address=localhost:8848
nacos.namespace=

3、复制test中的模板

网关流控需要新建

GatewayFlowRuleNacosProvider

package com.alibaba.csp.sentinel.dashboard.rule.nacos;

import com.alibaba.csp.sentinel.dashboard.datasource.entity.gateway.GatewayFlowRuleEntity;
import com.alibaba.csp.sentinel.dashboard.rule.DynamicRuleProvider;
import com.alibaba.csp.sentinel.datasource.Converter;
import com.alibaba.csp.sentinel.util.StringUtil;
import com.alibaba.nacos.api.config.ConfigService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.util.ArrayList;
import java.util.List;

@Component("gatewayFlowRuleNacosProvider")
public class GatewayFlowRuleNacosProvider implements DynamicRuleProvider> {

    @Autowired
    private ConfigService configService;
    @Autowired
    private Converter> converter;

    @Override
    public List getRules(String appName) throws Exception {
        String rules = configService.getConfig(appName + NacosConfigUtil.GATEWAY_FLOW_DATA_ID_POSTFIX,
            NacosConfigUtil.GROUP_ID, 3000);
        if (StringUtil.isEmpty(rules)) {
            return new ArrayList<>();
        }
        return converter.convert(rules);
    }
}

GatewayFlowRuleNacosPublisher

package com.alibaba.csp.sentinel.dashboard.rule.nacos;

import com.alibaba.csp.sentinel.dashboard.datasource.entity.gateway.GatewayFlowRuleEntity;
import com.alibaba.csp.sentinel.dashboard.rule.DynamicRulePublisher;
import com.alibaba.csp.sentinel.datasource.Converter;
import com.alibaba.csp.sentinel.util.AssertUtil;
import com.alibaba.nacos.api.config.ConfigService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.util.List;

@Component("gatewayFlowRuleNacosPublisher")
public class GatewayFlowRuleNacosPublisher implements DynamicRulePublisher> {

    @Autowired
    private ConfigService configService;
    @Autowired
    private Converter, String> converter;

    @Override
    public void publish(String app, List rules) throws Exception {
        AssertUtil.notEmpty(app, "app name cannot be empty");
        if (rules == null) {
            return;
        }
        configService.publishConfig(app + NacosConfigUtil.GATEWAY_FLOW_DATA_ID_POSTFIX,
            NacosConfigUtil.GROUP_ID, converter.convert(rules));
    }
}

NacosConfig

package com.alibaba.csp.sentinel.dashboard.rule.nacos;

import com.alibaba.csp.sentinel.dashboard.datasource.entity.gateway.GatewayFlowRuleEntity;
import com.alibaba.csp.sentinel.dashboard.datasource.entity.rule.FlowRuleEntity;
import com.alibaba.csp.sentinel.datasource.Converter;
import com.alibaba.fastjson.JSON;
import com.alibaba.nacos.api.config.ConfigFactory;
import com.alibaba.nacos.api.config.ConfigService;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.List;

@Configuration
public class NacosConfig {

    @Bean
    public Converter, String> flowRuleEntityEncoder() {
        return JSON::toJSONString;
    }

    @Bean
    public Converter> flowRuleEntityDecoder() {
        return s -> JSON.parseArray(s, FlowRuleEntity.class);
    }

    @Bean
    public Converter, String> gatewayFlowRuleEntityEncoder() {
        return JSON::toJSONString;
    }

    @Bean
    public Converter> gatewayFlowRuleEntityDecoder() {
        return s -> JSON.parseArray(s, GatewayFlowRuleEntity.class);
    }

    @Bean
    public ConfigService nacosConfigService() throws Exception {
        return ConfigFactory.createConfigService("localhost");
    }
}

NacosConfigUtil

package com.alibaba.csp.sentinel.dashboard.rule.nacos;

/**
 * @author Eric Zhao
 * @since 1.4.0
 */
public final class NacosConfigUtil {

    public static final String GROUP_ID = "SENTINEL_GROUP";
    
    public static final String FLOW_DATA_ID_POSTFIX = "-flow-rules";
    public static final String GATEWAY_FLOW_DATA_ID_POSTFIX = "-gateway-flow-rules";
    public static final String PARAM_FLOW_DATA_ID_POSTFIX = "-param-rules";
    public static final String CLUSTER_MAP_DATA_ID_POSTFIX = "-cluster-map";

    /**
     * cc for `cluster-client`
     */
    public static final String CLIENT_CONFIG_DATA_ID_POSTFIX = "-cc-config";
    /**
     * cs for `cluster-server`
     */
    public static final String SERVER_TRANSPORT_CONFIG_DATA_ID_POSTFIX = "-cs-transport-config";
    public static final String SERVER_FLOW_CONFIG_DATA_ID_POSTFIX = "-cs-flow-config";
    public static final String SERVER_NAMESPACE_SET_DATA_ID_POSTFIX = "-cs-namespace-set";

    private NacosConfigUtil() {}
}

 修改GatewayFlowRuleController

使用gatewayFlowRuleNacosProvider和gatewayFlowRuleNacosPublisher替换 sentinelApiClient

/*    @Autowired
    private SentinelApiClient sentinelApiClient;*/

    @Autowired
    @Qualifier("gatewayFlowRuleNacosProvider")
    private DynamicRuleProvider> ruleProvider;
    @Autowired
    @Qualifier("gatewayFlowRuleNacosPublisher")
    private DynamicRulePublisher> rulePublisher;
