spring-boot - 无法在 Spring 引导应用程序中禁用 ContextCredentialsAutoConfiguration

Question

我正在开发一个 Spring Batch 应用程序，它应该只对特定的配置文件使用 aws cloud。目前我有一个使用 aws 的配置文件和另一个不应该使用的配置文件，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)

对于使用 AWS 配置文件的配置，我有以下内容:

@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;
}

}

对于我的 localDev 配置文件，我有以下内容:

@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 配置文件 (-Dspring.profiles.active=localDev) 运行 Spring Boot Main 类时，出现以下错误:

当我开始调试时，我发现一旦将 spring-cloud-aws-autoconfigure 添加到 pom.xml 中，似乎就无法在运行时为非 aws 环境禁用 aws autoconfigure。
我尝试了以下方法:

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

但还是不行，有什么想法吗？

提前致谢!

至于 spring cloud Brixton.SR7 的版本，要手动配置您将在 application.properties 中设置的区域(或 .xml、.yml，无论您使用什么)。此参数应该仅适用于您的开发环境，除非您确实需要指定它。

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

我还必须为开发人员设置下一个属性，但也许您不需要它。

cloud.aws.stack.auto=false
