Sentinel1.8.6更改配置同步到nacos(项目是Gateway)

news 2025/6/25 8:01:02

本次修改的源码在：https://gitee.com/stonic-open-source/sentinel-parent

一

下载源码 地址：https://github.com/alibaba/Sentinel/releases/tag/1.8.6

二

导入idea，等待maven下载好各种依赖

三

打开sentile-dashboard这个模块，打开resources下的application.properties配置

把下列配置加进去

#你的nacos地址
nacos.server-addr=localhost:8148  
#准备把sentinel配置同步到的nacos命名空间
nacos.namespace=zixun_dev 
#你的nacos用户名
nacos.username=nacos 
#你的nacos密码
nacos.password=nacos

四

打开sentile-dashboard下的pom，把sentinel-datasource-nacos的<scope>test</scope>删掉(记得刷新一下maven)

刷新maven

五

rule文件夹下新建一个nacos目录

把图中test的NacosConfig和Util复制到nacos目录下

六

然后在nacos下新建一个NacosInfoConfig类，用于读取配置文件

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;/*** @author 刘辉* @description* @since 2024/5/17 上午10:26*/
@Component
@ConfigurationProperties(prefix = "nacos")
public class NacosInfoConfig {private String serverAddr;private String username;private String password;private String namespace;public String getServerAddr() {return serverAddr;}public void setServerAddr(String serverAddr) {this.serverAddr = serverAddr;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public String getNamespace() {return namespace;}public void setNamespace(String namespace) {this.namespace = namespace;}
}

七

然后修改一下NacosConfigUtil的内容  其中group_id需要和你springcloud项目配置的nacos中sentinel的groupId一致

public final class NacosConfigUtil {/*** 同步到nacos生成的groupId 没有可不填*/public static final String GROUP_ID = "zixun_sentinel";/*** 同步到nacos生成的sentinel api规则的后缀*/public static final String API_DATA_ID_POSTFIX = "-api-rules";/*** 同步到nacos生成的sentinel 流控规则的后缀*/public static final String FLOW_DATA_ID_POSTFIX = "-flow-rules";/*** 同步到nacos生成的sentinel 参数规则的后缀*/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() {}
}

八

修改NacosConfig文件

将配置的nacos信息注入进去，且新增gateway流控配置和sentinel全局规则的配置

import java.util.List;
import java.util.Properties;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;import com.alibaba.csp.sentinel.dashboard.datasource.entity.gateway.ApiDefinitionEntity;

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;/*** @author Eric Zhao* @since 1.4.0*/
@Configuration
public class NacosConfig {@Autowiredprivate NacosInfoConfig nacosInfoConfig;/*** sentinel本地流控 编码器* @return*/@Beanpublic Converter<List<FlowRuleEntity>, String> flowRuleEntityEncoder() {return JSON::toJSONString;}/*** sentinel 针对gateway流控配置 编码器* @return*/@Beanpublic Converter<List<GatewayFlowRuleEntity>, String> flowRuleGatewayEntityEncoder() {return JSON::toJSONString;}/*** sentinel 针对全局流控配置 编码器* @return*/@Beanpublic Converter<List<ApiDefinitionEntity>, String> flowRuleNacosEntityEncoder() {return JSON::toJSONString;}/*** sentinel本地流控 解码器* @return*/@Beanpublic Converter<String, List<FlowRuleEntity>> flowRuleEntityDecoder() {return s -> JSON.parseArray(s, FlowRuleEntity.class);}/*** sentinel 针对gateway流控配置 解码器* @return*/@Beanpublic Converter<String, List<GatewayFlowRuleEntity>> flowRuleGatewayEntityDecoder() {return s -> JSON.parseArray(s, GatewayFlowRuleEntity.class);}/*** sentinel 针对全局流控配置 解码器* @return*/@Beanpublic Converter<String, List<ApiDefinitionEntity>> flowRuleNacosEntityDecoder() {return s -> JSON.parseArray(s, ApiDefinitionEntity.class);}@Beanpublic ConfigService nacosConfigService() throws Exception {Properties properties = new Properties();//Nacos地址properties.put("serverAddr", nacosInfoConfig.getServerAddr());//Nacos用户名properties.put("username", nacosInfoConfig.getUsername());//Nacos密码properties.put("password", nacosInfoConfig.getPassword());properties.put("namespace", nacosInfoConfig.getNamespace());return ConfigFactory.createConfigService(properties);}
}

九

新建FlowRuleGatewayProvider和FlowRuleGatewayPublisher  分别提供gateway添加和查询的操作

import java.util.ArrayList;
import java.util.List;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Component;import com.alibaba.csp.sentinel.dashboard.datasource.entity.gateway.GatewayFlowRuleEntity;

@Component("flowRuleGatewayProvider")
public class FlowRuleGatewayProvider implements DynamicRuleProvider<List<GatewayFlowRuleEntity>> {@Autowiredprivate ConfigService configService;@Autowired@Qualifier("flowRuleGatewayEntityDecoder")private Converter<String, List<GatewayFlowRuleEntity>> converter;@Overridepublic List<GatewayFlowRuleEntity> getRules(String appName) throws Exception {String rules = configService.getConfig(appName + NacosConfigUtil.FLOW_DATA_ID_POSTFIX,NacosConfigUtil.GROUP_ID, 3000);if (StringUtil.isEmpty(rules)) {return new ArrayList<>();}return converter.convert(rules);}
}
import java.util.List;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Component;import com.alibaba.csp.sentinel.dashboard.datasource.entity.gateway.GatewayFlowRuleEntity;

import com.alibaba.csp.sentinel.datasource.Converter;
import com.alibaba.csp.sentinel.util.AssertUtil;
import com.alibaba.nacos.api.config.ConfigService;
import com.alibaba.nacos.api.config.ConfigType;/*** @author Eric Zhao* @since 1.4.0*/
@Component("flowRuleGatewayPublisher")
public class FlowRuleGatewayPublisher implements DynamicRulePublisher<List<GatewayFlowRuleEntity>> {@Autowiredprivate ConfigService configService;@Autowired@Qualifier("flowRuleGatewayEntityEncoder")private Converter<List<GatewayFlowRuleEntity>, String> converter;@Overridepublic void publish(String app, List<GatewayFlowRuleEntity> rules) throws Exception {AssertUtil.notEmpty(app, "app name cannot be empty");if (rules == null) {return;}configService.publishConfig(app + NacosConfigUtil.FLOW_DATA_ID_POSTFIX,NacosConfigUtil.GROUP_ID, converter.convert(rules), ConfigType.JSON.getType());}
}

新建FlowRuleApiProvider和FlowRuleApiPublisher  分别提供sentinel全局规则 查询和编辑

import java.util.ArrayList;
import java.util.List;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Component;import com.alibaba.csp.sentinel.dashboard.datasource.entity.gateway.ApiDefinitionEntity;

import com.alibaba.csp.sentinel.datasource.Converter;
import com.alibaba.csp.sentinel.util.StringUtil;
import com.alibaba.nacos.api.config.ConfigService;/*** @author Eric Zhao* @since 1.4.0*/
@Component("flowRuleNacosProvider")
public class FlowRuleApiProvider implements DynamicRuleProvider<List<ApiDefinitionEntity>> {@Autowiredprivate ConfigService configService;@Autowired@Qualifier("flowRuleNacosEntityDecoder")private Converter<String, List<ApiDefinitionEntity>> converter;@Overridepublic List<ApiDefinitionEntity> getRules(String appName) throws Exception {String rules = configService.getConfig(appName + NacosConfigUtil.API_DATA_ID_POSTFIX,NacosConfigUtil.GROUP_ID, 3000);if (StringUtil.isEmpty(rules)) {return new ArrayList<>();}return converter.convert(rules);}
}

import java.util.List;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Component;import com.alibaba.csp.sentinel.dashboard.datasource.entity.gateway.ApiDefinitionEntity;
import com.alibaba.csp.sentinel.dashboard.rule.DynamicRulePublisher;
import com.alibaba.csp.sentinel.dashboard.rule.nacos.NacosConfigUtil;
import com.alibaba.csp.sentinel.datasource.Converter;
import com.alibaba.csp.sentinel.util.AssertUtil;
import com.alibaba.nacos.api.config.ConfigService;
import com.alibaba.nacos.api.config.ConfigType;/*** @author Eric Zhao* @since 1.4.0*/
@Component("flowRuleNacosPublisher")
public class FlowRuleApiPublisher implements DynamicRulePublisher<List<ApiDefinitionEntity>> {@Autowiredprivate ConfigService configService;@Autowired@Qualifier("flowRuleNacosEntityEncoder")private Converter<List<ApiDefinitionEntity>, String> converter;@Overridepublic void publish(String app, List<ApiDefinitionEntity> rules) throws Exception {AssertUtil.notEmpty(app, "app name cannot be empty");if (rules == null) {return;}configService.publishConfig(app + NacosConfigUtil.API_DATA_ID_POSTFIX,NacosConfigUtil.GROUP_ID, converter.convert(rules), ConfigType.JSON.getType());}
}

自此配置方面就结束了，接下来上controller代码

十

找到controller下的gateway目录两个controller

下边的增删改查方法都有修改，修改的地方比较多，这里我直接贴主要替换的代码和controller全部代码大家直接粘贴
