AWS Beanstalk：无法确定嵌入式数据库驱动程序类

【中文标题】AWS Beanstalk：无法确定嵌入式数据库驱动程序类

【英文标题】：AWS Beanstalk: Cannot determine embedded database driver class

【发布时间】：2016-07-24 17:28:15

【问题描述】：

我有一个 spring boot 应用程序，它在我的本地实例上运行良好（通过 Intellij），但是在 AWS BEanstalk 上部署时，应用程序抛出以下错误（抱歉格式化。这就是 spring 生成异常的方式）：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfig uration$JdbcTemplateConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationExcept ion: Could not autowire field: private javax.sql.DataSource org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration$JdbcTemplateConfigur ation.dataSource; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in cla ss path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration$NonEmbeddedConfiguration.class]: Bean instantiation via factor y method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cann ot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (the profiles "aws" are currently active).

application.properties

spring.profiles.active=aws
dynamodb.tablename=my_dynamodb_table

application-aws.properties

spring.profiles.active=aws

应用程序使用 dynamodb 中的表。这可能是因为我可能需要在 AWS 中设置权限以允许 beanstalk 与 dynamodb 对话？如果是这样，请告诉我该怎么做。

我的 EC2 实例是 tomcat8 类型。

只需将其添加到您的 pom 中即可。

<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <version>1.3.156</version>
</dependency>
