spring-cloud-aws错误:找不到引擎‘aurora’的数据库类型

Question

我有一个spring引导应用程序，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，

我得到以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dubba': Invocation of init method failed; nested exception is java.lang.IllegalStateException: No database type found for engine:'aurora'

Answer 1

这是因为Aurora不是正式的框架(Spring Cloud for Amazon Web Services)，即使它基本上是MySQL。

它是1.1.0版本的一部分，截至今天(2016年5月11日)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。
