禁用Spring Cloud AWS自动配置以进行本地开发 [英] Disable Spring Cloud AWS autoconfiguration for local development

问题描述

我使用以下Maven依赖关系，该依赖关系会自动配置所有必需的参数，以使我的项目在AWS上工作:

I use the following Maven dependency which autoconfigures all necessary parameters to make my project work on AWS:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-aws</artifactId>
    <version>1.2.2.RELEASE</version>
</dependency>

不过，根据AWS，我没有任何关键功能，只是在运行时从S3加载一些文件.因此，在本地开发(以及测试)期间，我不需要任何AWS自动配置.

I don't have any critical functionality depending on AWS though, it's just to load a few files from S3 at runtime. So during local development (and also testing), I don't need any AWS autoconfiguration.

我在本地运行时遇到的逻辑错误是:

The logical error I get when running locally is:

...
Caused by: java.lang.IllegalStateException: There is no EC2 meta data available, because the application is not running in the EC2 environment. Region detection is only possible if the application is running on a EC2 instance
    at org.springframework.util.Assert.state(Assert.java:392) ~[spring-core-4.3.2.RELEASE.jar:4.3.2.RELEASE]

...

是否有用于测试和本地开发的干净，可行的解决方案?

Is there a clean, working solution for both testing and local development?

推荐答案

我已经使用surefire插件解决了此问题:

I've solved this for tests using the surefire plugin:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.21.0</version>
    <configuration>
        <classpathDependencyExcludes>
            <classpathDependencyExcludes>org.springframework.cloud:spring-cloud-aws-autoconfigure</classpathDependencyExcludes>
        </classpathDependencyExcludes>
    </configuration>
</plugin>

通过将以下变量设置为VM参数或在Spring Cloud Config Server中解决了本地开发问题:

Local development was solved setting the following variables as VM parameters or in the Spring Cloud Config Server:

cloud.aws.region.auto=false
cloud.aws.region.static=us-east-1

您可以为cloud.aws.region.static使用任何值，但是必须有一个值.

You can use any value for cloud.aws.region.static, but there has to be one.

我在不同的地方阅读了这两种解决方案，并认为将来将它们结合在一起可能会对某人有所帮助.

I read both solutions in different places and thought it might help someone in the future to see them combined here.
