Question

我有一个spring boot应用程序，它在我的本地实例上运行得很好（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）：< / p>

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

应用程序在dynamodb中使用表。这可能是因为我可能需要在AWS中设置权限以允许beanstalk与dynamodb交谈吗？如果是这样，请告诉我如何做到这一点。
