無法禁用Spring引導應用程序中的ContextCredentialsAutoConfiguration

Question

我正在使用僅適用於特定配置文件的aws雲的Spring Batch應用程序。目前我有一個使用aws和另一個應用程序的配置文件，因爲它使用本地數據庫，本地文件等在本地運行應用程序（同時AWS配置文件將使用RDS，S3等）

對於我的配置使用AWS檔案I具備以下條件：

@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; 
} 

} 

對於我localDev檔案我有以下幾點：

@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; 
} 

} 

當我嘗試使用localDev輪廓運行春季啓動主類（-Dspring.profiles.active=localDev）我得到foll由於錯誤：

當我開始調試，我發現，一旦你添加彈簧雲AWS-自動配置到你的pom.xml則似乎沒有方法來禁用非AWS環境在運行時自動氣象站自動配置。
我試過如下：

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

，但仍然無法工作，任何想法嗎？

在此先感謝！

Answer 1

至於春天的雲Brixton.SR7的版本，手動配置您將在您的application.properties（或無論您使用的.xml，.yml）中設置的區域。除非您確實需要指定它，否則此參數應僅用於您的開發環境。

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

我還必須爲dev設置下一個屬性，但也許你不需要它。在http://cloud.spring.io/spring-cloud-static/spring-cloud-aws/1.1.4.RELEASE/#_region_configuration

Answer 2

cloud.aws.stack.auto=false 

多個參考信息。在最後，我決定從我的pom.xml完全移除彈簧雲AWS-自動配置依賴性。

<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> 

，我參考使用該AWS環境如下Java配置文件在上述文件中：：
我提供以下信息創建的AWS-config.xml文件資源下

@Configuration 
@Profile("!localDev") 

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

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

    @Autowired 
    private ResourceLoader resourceLoader;
