前言

本次使用的版本号是springcloud(Greenwich.SR2) springboot(2.1.6.RELEASE)

hystrix dashboard

单节点监控(

一、创建监控页面

1、引入GAV依赖pom文件

            </plugin>
        </plugins>
    </build>
</project>

2、application.properties

server.port=10010
spring.application.name=sys-tool-dashboard

3、启动类头配置

@SpringBootApplication
@EnableHystrixDashboard

4、启动

5、访问

http://localhost:10010/hystrix

6、效果

创建监控方

1、引入gav

    <dependencies>
        <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.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

application.properties

server.port=10011
spring.application.name=company-info-test
#开启所有监控断点，也可以单独打开hystrix.stream
#management.endpoints.web.exposure.include=hystrix.stream
#  health,info,env......
management.endpoints.web.exposure.include=*
management.endpoint.health.show-details=always

3、使组件生效，在启动类种配置生效注解

//(exclude={DataSourceAutoConfiguration.class})去除自动连接数据库的配置，原因是父文件中引入了JPA
@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
@EnableCircuitBreaker

4,编写controller接口以及使用hystrix做容错

接口

@RestController
@RequestMapping("info-test")
public class TestDashBoard {
    @Autowired
    private StoreIntegration storeIntegration;
    @GetMapping("dashboard")
    public Object testDashBoard() {
        return storeIntegration.getStores();
    }
}

hystrix容错

@Component
public class StoreIntegration {

    @HystrixCommand(fallbackMethod = "defaultStores")
    public Object getStores() {
        return "success";
        //do stuff that might fail
    }

    public Object defaultStores() {
        return "error";
                /* something useful */
    }
}
