将我的 Spring Boot 应用程序部署到 CF

更新
我的申请
@SpringBootApplication
public class EdollarApplication
@Autowired
private DataSource dataSource;
public static void main(String[] args)
SpringApplication.run(EdollarApplication.class, args);
DataSourceConfiguration.java
@Configuration
@Profile("cloud")
public class DataSourceConfiguration
@Bean
public Cloud cloud()
return new CloudFactory().getCloud();
@Bean
@ConfigurationProperties(DataSourceProperties.PREFIX)
public DataSource dataSource()
return cloud().getSingletonServiceConnector(DataSource.class, null);
日志中没有错误,但是我无法访问我在应用程序中定义的 URL。示例日志如下所示

我在这里错过了什么?
【问题讨论】:
可能值得确认...EdollarApplication
在名为demo
的根包中吗?它是否在命令行上运行?即java -jar <app>-<version>.jar
?
可能不是问题,但您的主课程中不需要@EnableAutoConfiguration
。
Spring Boot
是否有开箱即用的示例或 Cloud Foundry 中的最低配置?
它已经开箱即用。虽然我现在想知道 - 鉴于您没有在上面显示,您的 manifest.yml
是什么样的?
我没有 manifest.yml。我需要一个吗?
【参考方案1】:
这是一个配置为在 Cloud Foundry 中运行的最小 Spring Boot 项目的示例:https://github.com/gratiartis/super-mini
我通过将以下 manifest.yml
放入项目的根目录中使其在 Cloud Foundry 中运行。
---
applications:
- name: super-mini
# Fork of https://github.com/cloudfoundry/java-buildpack
# For stability, keep your own fork.
buildpack: https://github.com/gratiartis/java-buildpack
memory: 512M
instances: 1
# Because the URL will be http://super-mini.cfapps.io/
host: super-mini
domain: cfapps.io
path: target/super-mini-1.0.0-SNAPSHOT.jar
请注意,可以添加以下内容来激活配置文件(即“云”):
env:
SPRING_PROFILES_ACTIVE: cloud
path
基于我从项目的根目录运行部署。我相信你已经猜到了,它是一个 Maven 构建,所以在 target
目录中创建了一个 .jar。
要部署,cd
到项目的根目录并运行:
cf push
以上将创建一个运行在http://super-mini.cfapps.io/hello的应用程序
看看 - 它现在正在运行。当然,我现在已经创建了那个应用程序名称,所以你不能使用它!
【讨论】:
我应该像你一样使用 mysql 作为配置文件名称吗?或者我需要将其更改为Cloud
,如上面的DataSourceConfiguration
。
我完全按照您的建议进行了操作。该应用程序已推送到云端,但我无法访问任何网址。事实上,在日志中我没有看到任何请求映射已被映射。
哦不...我只是在应用程序资源文件夹中有一个application.yml
,其配置文件名为mysql
,它定义了连接详细信息。这是一种让它工作的简单方法,但 Spring Cloud 的东西可能会更好。
它是否在日志中显示应用程序启动?他们应该提供一些关于应用程序是否已部署、它被称为什么、启动过程中是否有任何问题等信息。
另外,您的应用程序日志记录配置到哪里?以上是关于如何将 Spring Boot 部署到 Cloud Foundry?的主要内容,如果未能解决你的问题,请参考以下文章
