spring-cloud-aws錯誤沒有找到引擎的數據庫類型：'極光'

Question

我有一個彈簧啓動應用程序，我試圖連接到RDS實例（MySQL）。這裏是我的應用程序

@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); 
    } 
} 

當我嘗試mvn spring-boot:run，

我收到以下錯誤：

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

這是因爲極光是沒有正式的框架（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（11.5.2016）在stable version。

Maven的依賴性：

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

當釋放版本可用Maven的，只需用RELEASE更換RC2。
