Hystrix Dashboard Hystrix Dashboard是一个独立的运用，则可以单独列个模块 1.引入依赖

    <dependencies>
        <!-- spring cloud alibaba nacos discovery 依赖 -->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            <version>2.2.3.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
        </dependency>
    </dependencies>

    <!--
        SpringBoot的Maven插件, 能够以Maven的方式为应用提供SpringBoot的支持，可以将
        SpringBoot应用打包为可执行的jar或war文件, 然后以通常的方式运行SpringBoot应用
     -->
    <build>
        <finalName>${artifactId}</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

2.配置文件

hystrix:
  dashboard:
    proxy-stream-allow-list: "127.0.0.1"

3.编写启动类

/**
 * <h1>hystrix dashboard 入口</h1>
 * */
@EnableDiscoveryClient
@SpringBootApplication
@EnableHystrixDashboard     // 开启 Hystrix Dashboard
public class HystrixDashboardApplication {

    public static void main(String[] args) {

        SpringApplication.run(HystrixDashboardApplication.class, args);
    }
}
