根据doc,我的应用程序应在/ health下提供hystrix数据。尽管打开了断路器,但我在该URL下看到的唯一一件事是

{"status":"UP"}


我希望看到这样的东西

{
    "hystrix": {
        "openCircuitBreakers": [
            "somedata::somedata"
        ],
        "status": "CIRCUIT_OPEN"
    },
    "status": "UP"
}


我错过了什么?

我的build.gradle

buildscript {
    ext {
        springBootVersion = '1.5.10.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }

}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'

group = 'com.somecompany'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}


ext {
    springCloudVersion = 'Edgware.SR1'
}

dependencies {
    compile('org.springframework.cloud:spring-cloud-starter-hystrix')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter-actuator')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
    }
}


应用类别

@EnableCircuitBreaker
@SpringBootApplication
public class HystrixDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(HystrixDemoApplication.class, args);
    }
}


Hystrix控制下的资源

@RestController
public class SomeResourceController {

    @HystrixCommand(fallbackMethod = "defaultValue", commandProperties = {@HystrixProperty(name="execution.isolation.thread.timeoutInMilliseconds", value="1500")})
    @RequestMapping(path = "/resource-with-hystrix", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
    public String someResource(){
        URI uri = URI.create("http://localhost:8080/some-resource");
        RestOperations restTemplate = new RestTemplate();
        return restTemplate.getForObject(uri, String.class);
    }

    private String defaultValue(){
        return "local value in case of something goes wrong";
    }
}

最佳答案

将运行状况端点设置为不敏感(默认):

endpoints.health.sensitive=false



  根据暴露端点的方式,敏感属性可以用作安全提示。例如,通过HTTP访问敏感端点时,它们将需要用户名/密码(如果未启用Web安全,则将其禁用)。


从运行状况端点的文档中:


  显示应用程序的运行状况信息(当应用程序是安全的时,通过未经身份验证的连接访问时为简单的“状态”,而在经过身份验证时则为完整的消息详细信息)。

关于java - Hystrix的状态未在/health下公开,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/48704018/
