如何在测试中禁用AWS参数存储自动配置？

Question

根据spring文档的说明，我添加了spring-cloud-starter-aws-parameter-store-config依赖项。现在，对于单元测试，我想禁用参数存储配置，但无法实现。

我尝试在test/application.properties中设置以下属性：

 aws.paramstore.enabled=false

尝试排除 AwsParamStoreBootstrapConfiguration.class 从AutoConfiguration中，但仍未能正常工作。

异常

我能使用另一种方法禁用paramstore，只需将(aws.paramstore.enabled=false) 属性添加到 bootstrap.properties 文件的测试资源文件夹中即可。这是一种更简单的解决方案。

旧的解决方案

我找出了解决方案。看起来 SpringBootTest 甚至在测试配置类之前加载 ssmClient ，以及在加载 application.properties 之前。解决方案是通过在 @SpringBootTest 上指定属性来禁用 paramstore。

@SpringBootTest(classes = MyApp.class, properties = {"aws.paramstore.enabled=false"})

@sidgate：如果我们在引导程序中添加属性并将其禁用，则需要为所有其他需要该属性的环境启用它。 - Som

只需在 src/test/resources/bootstrap.properties 中添加即可。 - sidgate
