本文主要是介绍springboot项目引入Sentinel熔断，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
本文是springboot项目+nacos进行引入，sentiel需自行按照部署
1.springboot包要是2.2.5或以上
<dubbo.version>2.7.7</dubbo.version><spring-boot.version>2.2.5.RELEASE</spring-boot.version><chainwork-boot.version>1.0.5-SNAPSHOT</chainwork-boot.version><nacos.version>0.2.7</nacos.version><spring-cloud-nacos-config.version>2.2.5.RELEASE</spring-cloud-nacos-config.version><spring-cloud.version>Hoxton.SR3</spring-cloud.version><spring-cloud-nacos-discovery.version>2.2.5.RELEASE</spring-cloud-nacos-discovery.version>
<!-- <arthas.version>3.4.3</arthas.version><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><nacos-client.version>1.4.1</nacos-client.version><redisson.version>3.13.6</redisson.version><spring-cloud-alibaba.version>2.2.5.RELEASE</spring-cloud-alibaba.version>2.项目后端需依赖包
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-openfeign</artifactId><version>${spring-cloud-alibaba.version}</version></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-sentinel</artifactId><version>${spring-cloud-alibaba.version}</version></dependency><!-- Sentinel数据源之 Nacos --><dependency><groupId>com.alibaba.csp</groupId><artifactId>sentinel-datasource-nacos</artifactId><version>1.8.0</version></dependency><dependency><groupId>com.alibaba.csp</groupId><artifactId>sentinel-web-servlet</artifactId><version>1.8.0</version></dependency><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.6</version></dependency><dependency><groupId>io.github.openfeign</groupId><artifactId>feign-httpclient</artifactId></dependency><dependency><groupId>javax.validation</groupId><artifactId>validation-api</artifactId><version>2.0.1.Final</version></dependency><dependency><groupId>org.hibernate</groupId><artifactId>hibernate-validator</artifactId><version>5.0.1.Final</version></dependency>3.项目前端需依赖包
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-openfeign</artifactId><version>${spring-cloud-alibaba.version}</version></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-sentinel</artifactId><version>${spring-cloud-alibaba.version}</version></dependency><dependency><groupId>com.alibaba.csp</groupId><artifactId>sentinel-datasource-nacos</artifactId><version>1.8.0</version></dependency><dependency><groupId>com.alibaba.csp</groupId><artifactId>sentinel-web-servlet</artifactId><version>1.8.0</version></dependency><dependency><groupId>io.github.openfeign</groupId><artifactId>feign-httpclient</artifactId></dependency><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.6</version></dependency><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>RELEASE</version><scope>compile</scope></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-lang3</artifactId></dependency>

#server:
# port: 8888
