Unable to verify integrity of data upload. Client calculated content hash (contentMD5: wlkGaKXnoDlHOZDR8aaw5Q== in base 64) didn't match hash (etag: c69e9c108f7f2e117e6101a91628736c in hex) calculated by Amazon S3. You may need to delete the data stored in Amazon S3. (metadata.contentMD5: wlkGaKXnoDlHOZDR8aaw5Q==, md5DigestStream: null, bucketName: zkjr, key: complain\1744704774681MlIsMEMucG5n.png)

网上找了一大圈不是废话都太多了就是没有用，直接说解决方案，在构建AmazonS3 添加一个SignerOverride 配置（重点是这个配置：conf.setSignerOverride(SignerFactory.VERSION_FOUR_UNSIGNED_PAYLOAD_SIGNER);）


        AWSCredentials credentials = new BasicAWSCredentials(accessKey, accessValue);
        ClientConfiguration conf = new ClientConfiguration();
        conf.setSignerOverride(SignerFactory.VERSION_FOUR_UNSIGNED_PAYLOAD_SIGNER);
        AmazonS3 amazonS3 = AmazonS3ClientBuilder.standard()
                .withCredentials(new AWSStaticCredentialsProvider(credentials))
                .withClientConfiguration(conf)
                .withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration(s3Address,"china"))
                .withPathStyleAccessEnabled(true)
                .build();

        return amazonS3;
