无法使用自定义端点配置从S3轮询
无法使用自定义端点配置从S3轮询
提问于 2020-03-30 12:24:58
我尝试使用spring-integration-aws从S3桶中轮询触发春季批处理作业。我的S3桶不是托管在亚马逊上，而是在本地的minio服务器上，所以我得到了一个自定义配置：
@Bean
public AmazonS3 amazonS3(ConfigProperties configProperties) {
return AmazonS3ClientBuilder.standard()
.withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("http://localhost:9001","eu-west-0")) // Region matches with minio region
.withPathStyleAccessEnabled(configProperties.getS3().isPathStyle())
.withCredentials(new AWSStaticCredentialsProvider(new BasicAWSCredentials(
configProperties.getS3().getAccessKey(), configProperties.getS3().getSecretKey()
))).build();
}我用这种方式定义了我的IntegrationFlow：
@Bean
public IntegrationFlow s3InboundFlow() {
S3RemoteFileTemplate template = new S3RemoteFileTemplate(new S3SessionFactory(amazonS3));
S3StreamingMessageSource s3StreamingMessageSource = new S3StreamingMessageSource(template);
s3StreamingMessageSource.setRemoteDirectory(String.format("%s/OUT/", configProperties.getS3().getBucketDataPath()));
return IntegrationFlows.from(s3StreamingMessageSource, configurer -> configurer
.id("s3InboundAdapter")
.autoStartup(true)
.poller(Pollers.fixedDelay(POLL, TimeUnit.SECONDS)))
.handle(jobLaunchingGateway(jobRepository)) // Launch a spring-batch job
.get();
}问题是，当轮询发生时，我得到了以下错误：

at org.springframework.integration.endpoint.AbstractPollingEndpoint.pollForMessage(AbstractPollingEndpoint.java:328)之所以会发生这种情况，是因为当接收到文件时，在spring-integration-aws中设置了一些头：
AbstractRemoteFileStreamingMessageSource.java
return getMessageBuilderFactory()
.withPayload(session.readRaw(remotePath))
.setHeader(IntegrationMessageHeaderAccessor.CLOSEABLE_RESOURCE, session)
.setHeader(FileHeaders.REMOTE_DIRECTORY, file.getRemoteDirectory())
.setHeader(FileHeaders.REMOTE_FILE, file.getFilename())
.setHeader(FileHeaders.REMOTE_HOST_PORT, session.getHostPort())
.setHeader(FileHeaders.REMOTE_FILE_INFO,
this.fileInfoJson ? file.toJson() : file);REMOTE_HOST_PORT头是由于getHostPort()方法而设置的。然后，getHostPort()在S3Session.java中调用getRegion()方法。
getRegion()方法在AmazonS3Client中没有检查用户在signing region字段中是否设置了一个值。它只检查主机是否匹配"amazonaws.com“模式。
@Override
public String getHostPort() {
Region region = this.amazonS3.getRegion().toAWSRegion();
return String.format("%s.%s.%s:%d", AmazonS3.ENDPOINT_PREFIX, region.getName(), region.getDomain(), 443);
} @Override
public synchronized Region getRegion() {
String authority = super.endpoint.getAuthority();
if (Constants.S3_HOSTNAME.equals(authority)) {
return Region.US_Standard;
} else {
Matcher m = Region.S3_REGIONAL_ENDPOINT_PATTERN.matcher(authority);
if (m.matches()) {
return Region.fromValue(m.group(1));
} else {
throw new IllegalStateException(
"S3 client with invalid S3 endpoint configured: " + authority);
}
}
}如何使用自定义端点配置从S3进行轮询？为什么getHostPort()方法不检查签名区域值？有可能解决这个问题吗？

是的，这是可以解决的。您只需扩展一个S3SessionFactory，就可以为您的自定义端点返回带有重写的getHostPort()方法的S3Session扩展。
public class MyS3SessionFactory extends S3SessionFactory {
private MyS3Session s3Session;
@Override
public S3Session getSession() {
return s3Session;
}
public MyS3SessionFactory(AmazonS3 amazonS3) {
super(amazonS3);
Assert.notNull(amazonS3, "'amazonS3' must not be null.");
this.s3Session = new MyS3Session(amazonS3);
}
}public class MyS3Session extends S3Session {
public MyS3Session(AmazonS3 amazonS3) {
super(amazonS3);
}
@Override
public String getHostPort() {
return "";
}
