这篇文章主要讲解了“如何使用Sentinel Dashboard动态推把数据同步到Nacos”,文中的讲解内容简单清晰,易于学习与理解,下面请大家跟着小编的思路慢慢深入,一起来研究和学习“如何使用Sentinel Dashboard动态推把数据同步到Nacos”吧!
企业建站必须是能够以充分展现企业形象为主要目的,是企业文化与产品对外扩展宣传的重要窗口,一个合格的网站不仅仅能为公司带来巨大的互联网上的收集和信息发布平台,成都创新互联公司面向各种领域:成都搬家公司等网站设计、全网整合营销推广解决方案、网站设计等建站排名服务。
准备工作:
下载Sentinel Dashboard的release版本。地址:https://github.com/alibaba/Sentinel/releases
一:修改pom.xml
中的sentinel-datasource-nacos的依赖,将
注释掉,这样才能在主程序中使用。
|
二:找到resources/app/scripts/directives/sidebar/sidebar.html
中的这段代码:
修改为:
这样修改之后就会跳转到FlowControllerV2的接口。
三:再项目com.alibaba.csp.sentinel.dashboard中新建一个nacos包来实现扩展功能。
@Component @ConfigurationProperties(prefix = "nacos.server") public class NacosConfigProperties { private String ip; private String port; private String namespace; private String groupId; public String getIp() { return ip; } public void setIp(String ip) { this.ip = ip; } public String getPort() { return port; } public void setPort(String port) { this.port = port; } public String getNamespace() { return namespace; } public void setNamespace(String namespace) { this.namespace = namespace; } public String getGroupId() { return groupId; } public void setGroupId(String groupId) { this.groupId = groupId; } public String getServerAddr() { return this.getIp()+":"+this.getPort(); } @Override public String toString() { return "NacosConfigProperties [ip=" + ip + ", port=" + port + ", namespace=" + namespace + ", groupId=" + groupId + "]"; } }
public final class NacosConfigConstant { public static final String FLOW_DATA_ID_POSTFIX = "-sentinel-flow"; public static final String GROUP_ID = "DEFAULT_GROUP"; }
@Configuration public class NacosConfig { @Autowired private NacosConfigProperties nacosConfigProperties; /** * 非常关键 这里将FlowRuleEntity转换成FlowRule才会对客户端生效 * @return FlowRule */ @Bean public Converter, String> flowRuleEntityEncoder() { return rules -> JSON.toJSONString(rules.stream().map(FlowRuleEntity::toRule).collect(Collectors.toList()), true); } @Bean public Converter
> flowRuleEntityDecoder() { return s -> JSON.parseArray(s, FlowRuleEntity.class); } @Bean public ConfigService nacosConfigService() throws Exception { Properties properties = new Properties(); properties.put(PropertyKeyConst.SERVER_ADDR, nacosConfigProperties.getServerAddr()); properties.put(PropertyKeyConst.NAMESPACE, nacosConfigProperties.getNamespace()); return ConfigFactory.createConfigService(properties); } }
四:编写动态推拉模式的扩展代码
@Component("flowRuleNacosProvider") public class FlowRuleNacosProvider implements DynamicRuleProvider> { private static Logger logger = LoggerFactory.getLogger(FlowRuleNacosProvider.class); @Autowired private NacosConfigProperties nacosConfigProperties; @Autowired private ConfigService configService; @Autowired private Converter
> converter; @Override public List getRules(String appName) throws Exception { String rules = configService.getConfig(appName + NacosConfigConstant.FLOW_DATA_ID_POSTFIX, nacosConfigProperties.getGroupId(), 3000); logger.info("从Nacos中拉取到限流规则信息:{}",rules); if (StringUtil.isEmpty(rules)) { return new ArrayList<>(); } return converter.convert(rules); } }
@Component("flowRuleNacosPublisher") public class FlowRuleNacosPublisher implements DynamicRulePublisher> { @Autowired private NacosConfigProperties nacosConfigProperties; @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 + NacosConfigConstant.FLOW_DATA_ID_POSTFIX, nacosConfigProperties.getGroupId(), converter.convert(rules)); } }
五:然后将FlowControllerV2中的默认DynamicRuleProvider
和DynamicRulePublisher
修改为:
@Autowired @Qualifier("flowRuleNacosProvider") private DynamicRuleProvider> ruleProvider; @Autowired @Qualifier("flowRuleNacosPublisher") private DynamicRulePublisher
> rulePublisher;
private void publishRules(/*@NonNull*/ String app) throws Exception { Listrules = repository.findAllByApp(app); rulePublisher.publish(app, rules); logger.info("添加限流规则成功{}", JSON.toJSONString(rules.stream().map(FlowRuleEntity::toRule).collect(Collectors.toList()), true)); }
六:application.properties配置文件
#nacos nacos.server.ip=localhost nacos.server.port=8848 nacos.server.namespace= nacos.server.group-id=DEFAULT_GROUP
