Docker Volume Plugin的Capabilities端点表明范围可以是 public static byte[] serialize(String json, Schema schema) throws IOException {
GenericDatumWriter<Object> writer = new GenericDatumWriter<>(schema);
ByteArrayOutputStream output = new ByteArrayOutputStream();
Encoder encoder = EncoderFactory.get().binaryEncoder(output, null);
DatumReader<Object> reader = new GenericDatumReader<>(schema);
Decoder decoder = DecoderFactory.get().jsonDecoder(schema, json);
Object datum = reader.read(null, decoder);
writer.write(datum, encoder);
encoder.flush();
output.flush();
return output.toByteArray();
}
public static String deserialize(byte[] avro, Schema schema) throws IOException {
GenericDatumReader<Object> reader = new GenericDatumReader(schema);
Decoder decoder = DecoderFactory.get().binaryDecoder(avro, null);
Object datum = reader.read(null, decoder);
ByteArrayOutputStream output = new ByteArrayOutputStream();
JsonEncoder encoder = EncoderFactory.get().jsonEncoder(schema, output);
DatumWriter<Object> writer = new GenericDatumWriter(schema);
writer.write(datum, encoder);
encoder.flush();
output.flush();
return new String(output.toByteArray(), "UTF-8");
}
或global。但是，我仍然不明白这种差异，特别是如果你是一个插件作者。
我在想＆＃34;本地＆＃34;如果你必须在local期间访问节点的资源，那么将需要它，而全局的资源可以从选项中找出所有内容。
