在 CloudFoundry 健康检查上使用 Eureka 的 Spring Boot 应用程序失败问题答案

【问题标题】：Spring Boot Application with Eureka on CloudFoundry healthcheck failed issue在 CloudFoundry 健康检查上使用 Eureka 的 Spring Boot 应用程序失败问题
【发布时间】：2016-06-21 18:09:17
【问题描述】：

我有一个 Spring Boot 应用程序（独立 jar 文件），我尝试将其部署在 CloudFoundry 上。我在 CloudFoundry 上创建了一个 Service Registry 实例，并尝试使用 CloudFoundry CLI 推送(cf push -p target\microservice-user-service-0.0.1-SNAPSHOT.jar) 我的应用程序(user-service)。

成功上传应用，服务绑定也成功。一旦启动，它会给出健康检查失败的问题

任何人都可以帮助我解决我所缺少的。我试图到处找到解决方案，但找不到。

【问题讨论】：

您是否在 JDK 8 和 Tomcat 8 上运行？
感觉你的应用启动失败了，能不能再看一下你的日志，把日志级别调低可能会更有用一点-logging.level.root = DEBUG
是的，我使用的是 JDK 8 和 Tomcat 8。Tomcat 实例是由 Spring Boot starter pom 自动创建的。
只检查根日志级别到调试
我用 'logging.level.root = DEBUG' 更新了日志。但原因不是很清楚，也可能是我无法理解。

【解决方案1】：

我现在可以解决问题了。我在 application.yml 文件中缺少 CloudFoundry PORT 环境变量。

这个link 解释了这个问题。

现在，application.yml 文件如下所示：

# HTTP Server
server:
  port: ${vcap.PORT}

# Spring properties
spring:
  application:
     name: ${vcap.application.name}
  cloud:
    services:
      registrationMethod: route 

---

spring:
  profiles: dev
---
security:
  basic:
    enabled: false

---

# Logging
logging:
  level:
    ROOT: INFO
    org.springframework.web: INFO

现在，我的应用程序已在 Cloud Foundry 上启动并运行。我可以使用 URL 访问服务。

【解决方案2】：

与POM配置无关。

你能在推送这个应用的时候设置域名和主机名吗？以下错误导致健康检查失败是由于：

Register host [localhost] at domain [null] for service [StandardService[Tomcat]]
