Question

在互联网上搜索嵌入式Java AWS S3模拟的良好解决方案后，似乎S3Ninja和S3Proxy似乎是最受欢迎的解决方案。

然而，似乎没有一种简单的方法可以通过编程方式解决这些问题。在放弃使用S3Ninja之后，我尝试使用S3Proxy，但它并没有完全正常工作。

Maven依赖

<dependency>
    <groupId>org.gaul</groupId>
    <artifactId>s3proxy</artifactId>
    <version>${s3proxy.version}</version>
    <scope>test</scope>
</dependency>

代码

String endpoint = "http://127.0.0.1:8085";
URI uri = URI.create(endpoint);
Properties properties = new Properties();
properties.setProperty("s3proxy.authorization", "none");
properties.setProperty("s3proxy.endpoint", endpoint);
properties.setProperty("jclouds.provider", "filesystem");
properties.setProperty("jclouds.filesystem.basedir", "/tmp/s3proxy");

ContextBuilder builder = ContextBuilder
        .newBuilder("filesystem")
        .credentials("x", "x")
        .modules(ImmutableList.<Module>of(new SLF4JLoggingModule()))
        .overrides(properties);
BlobStoreContext context = builder.build(BlobStoreContext.class);
BlobStore blobStore = context.getBlobStore();

S3Proxy s3Proxy = S3Proxy.builder().awsAuthentication("x", "x").endpoint(uri).keyStore("", "").blobStore(blobStore).build();
s3Proxy.start();

BasicAWSCredentials awsCredentials = new BasicAWSCredentials("x", "x");

AmazonS3Client client = new AmazonS3Client(awsCredentials, new ClientConfiguration());
client.setEndpoint(endpoint);

// Should Throw AWS Client Exception as Bucket / Key does not exist!
GetObjectRequest objectRequest = new GetObjectRequest("bucket", "key");
S3Object object = client.getObject(objectRequest);

s3Proxy.stop();

异常

真的很感激任何帮助。我确信这是与AWS S3交互的许多Java集成测试的一个重要要求。

只是为了评论原因是因为您的项目使用了冲突版本的gson。 S3Proxy的dep需要gson 2.5。

核心基于 ladon-S3-server，并且只有很少的 servlet。
