Pivotal Cloud Foundry Plus MySql数据库 [英] Pivotal Cloud Foundry Plus MySql DB

问题描述

1. 我在Pivotal Cloud Foundry上有一个正在运行的Web服务应用程序。


2. 我向其中添加了一个服务，即MySql DB，并将其与Web服务应用程序。


3. 我的问题是如何在春季启动中使用Java API和Cloud Foundry API获取My Sql db的数据源。

我尝试过的事情：

 public class Configuration {
        @Configuration
        @Profile("cloud")
        static class CloudConfiguration {
            @Bean
            public DataSource dataSource() {
                CloudFactory cloudFactory = new CloudFactory();
                Cloud cloud = cloudFactory.getCloud();
                String serviceID = cloud.getServiceID();
                return cloud.getServiceConnector(serviceID, DataSource.class, null);
            }
 }

执行的方法：

Configuration.CloudConfiguration cloudConfiguration = new CloudConfiguration();
        cloudConfiguration.dataSource();

我得到错误：

我得到像找不到合适的CloudConnector一样，从此代码中获取CloudException， getCloud（）方法将引发CloudException。

I get CloudExceptionfrom this code like no suitable CloudConnector is found, the getCloud() method throws a CloudException.

推荐答案

1将以下依赖项添加到pom.xml

1 Add below dependencies to your pom.xml

    <dependency>
        <groupId>io.pivotal.spring.cloud</groupId>
        <artifactId>spring-cloud-services-starter-config-client</artifactId>
    </dependency>

OR

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-spring-service-connector</artifactId>
    <version>1.2.3.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-cloudfoundry-connector</artifactId>
    <version>1.2.3.RELEASE</version>
</dependency>

2定义数据源：

public class CloudConfig extends AbstractCloudConfig {
        @Bean
        public DataSource dataSource() {
            DataSource dataSource = connectionFactory().dataSource();
            return dataSource;
        }
}

OR

public class CloudConfig extends AbstractCloudConfig {
        @Bean
        public DataSource inventoryDataSource() {
            return connectionFactory().dataSource("mysql-db-service");
        }
}
