【问题描述】：

我有一个 Spring Boot 应用程序，我正在尝试连接到 RDS 实例 (MySQL)。这是我的应用程序

@SpringBootApplication
@EnableRdsInstance(databaseName="*****", dbInstanceIdentifier="****", username="****",password="******")
@EnableContextCredentials(accessKey="*****", secretKey="****")
@EnableContextRegion(region="****")
public class Application extends SpringBootServletInitializer{

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

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

当我尝试mvn spring-boot:run时，

我收到以下错误：

【解决方案1】：

这是因为 Aurora 没有正式加入框架 (Spring Cloud for Amazon Web Services)，尽管它基本上是 MySQL。

它是 1.1.0 版本的一部分，截至今天 (11.5.2016) 在stable version。

Maven 依赖：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-aws-jdbc</artifactId>
    <version>1.1.0.RC2</version>
</dependency>

当发布版本在 Maven 上可用时，只需将 RC2 替换为 RELEASE。
