无法禁用Spring引导应用程序中的ContextCredentialsAutoConfiguration

Question

我正在使用仅适用于特定配置文件的aws云的Spring Batch应用程序。目前我有一个使用aws和另一个应用程序的配置文件，因为它使用本地数据库，本地文件等在本地运行应用程序（同时AWS配置文件将使用RDS，S3等）

对于我的配置使用AWS档案I具备以下条件：

@Configuration 
@Profile("!localDev") 

public class FileReaderConfigAWS { 

@Value("${cloud.aws.s3.bucket}") 
private String amazonS3Bucket; 

@Autowired 
private ResourceLoader resourceLoader; 

private static final Logger logger = LoggerFactory.getLogger(FileReaderConfigAWS.class); 


@Bean 
@StepScope 
public FlatFileItemReader<Object> flatFileReader(@Value("#{jobParameters['inputFile']}") String inputFile, LineMapper 
    lineMapper) { 
    FlatFileItemReader<Object> flatFileItemReader = new FlatFileItemReader<>(); 

    flatFileItemReader.setResource(resourceLoader.getResource("s3://" + this.amazonS3Bucket + "/" + inputFile)); 

    flatFileItemReader.setLineMapper(lineMapper); 

    return flatFileItemReader; 
} 


@Bean 
public AbstractFileValidator inputFileValidator() { 
    InputS3Validator inputS3Validator = new InputS3Validator(); 
    inputS3Validator.setRequiredKeys(new String[]{InputFileSystemValidator.INPUT_FILE}); 
    return inputS3Validator; 
} 

} 

对于我localDev档案我有以下几点：

@Profile("localDev") 
@Configuration 
public class FileReaderConfigLocalDev { 


@Bean 
@StepScope 
public FlatFileItemReader<Object> flatFileReader(@Value("#{jobParameters['inputFile']}") String inputFile, LineMapper lineMapper) { 
    FlatFileItemReader<Object> flatFileItemReader = new FlatFileItemReader<>(); 
    flatFileItemReader.setResource(new FileSystemResource(inputFile)); 

    flatFileItemReader.setLineMapper(lineMapper); 

    return flatFileItemReader; 
} 

@Bean 
public AbstractFileValidator inputFileValidator() { 
    InputFileSystemValidator inputFileValidator = new InputFileSystemValidator(); 
    inputFileValidator.setRequiredKeys(new String[]{InputFileSystemValidator.INPUT_FILE}); 
    return inputFileValidator; 
} 

} 

当我尝试使用localDev轮廓运行春季启动主类（-Dspring.profiles.active=localDev）我得到foll由于错误：

当我开始调试，我发现，一旦你添加弹簧云AWS-自动配置到你的pom.xml则似乎没有方法来禁用非AWS环境在运行时自动气象站自动配置。
我试过如下：

@EnableAutoConfiguration(exclude = {ContextCredentialsAutoConfiguration.class, ContextStackAutoConfiguration.class}) 

，但仍然无法工作，任何想法吗？

在此先感谢！

Answer 1

至于春天的云Brixton.SR7的版本，手动配置您将在您的application.properties（或无论您使用的.xml，.yml）中设置的区域。除非您确实需要指定它，否则此参数应仅用于您的开发环境。

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

我还必须为dev设置下一个属性，但也许你不需要它。在http://cloud.spring.io/spring-cloud-static/spring-cloud-aws/1.1.4.RELEASE/#_region_configuration

Answer 2

cloud.aws.stack.auto=false 

多个参考信息。在最后，我决定从我的pom.xml完全移除弹簧云AWS-自动配置依赖性。

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:aws-context="http://www.springframework.org/schema/cloud/aws/context" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
         http://www.springframework.org/schema/beans/spring-beans-4.1.xsd 
         http://www.springframework.org/schema/cloud/aws/context 
         http://www.springframework.org/schema/cloud/aws/context/spring-cloud-aws-context-1.0.xsd"> 

    <aws-context:context-credentials> 
     <aws-context:instance-profile-credentials/> 
     <aws-context:simple-credentials access-key="${cloud.aws.credentials.accessKey:}" secret-key="${cloud.aws.credentials.secretKey:}"/> 
    </aws-context:context-credentials> 

    <aws-context:context-region region="${cloud.aws.region.static:}"/> 
    <aws-context:context-resource-loader/> 
</beans> 

，我参考使用该AWS环境如下Java配置文件在上述文件中：：
我提供以下信息创建的AWS-config.xml文件资源下

@Configuration 
@Profile("!localDev") 

@ImportResource("classpath:/aws-config.xml") 
public class FileReaderConfigAWS { 

    @Value("${cloud.aws.s3.bucket}") 
    private String amazonS3Bucket; 

    @Autowired 
    private ResourceLoader resourceLoader;
