MessagePack Java Jackson 在不关闭输入流（input stream）的情况下反序列化多变量
com.fasterxml.jackson.databind.ObjectMapper在读取输入流变量的时候默认的将会关闭输入流。 如果你不希望关闭输入流，你可以设置JsonParser.Feature.AUTO_CLOSE_SOURCE参数为 false。 本测试方法，可以在https://github.com/cwiki-us-demo/serialize-deserialize-demo-java/blob/master/src/test/java/com/insight/demo/serialize/MessagePackSerializer.java中找到。 /** * Serialization Not Close input stream */ @Test public void testMessagePackSerializationNotCloseInputStream() { logger.debug("testMessagePackSerializationNotCloseInputStream"); try { File tempFile = File.createTempFile("messagepack-", "-cwiki.us"); MessagePacker packer = MessagePack.newDefaultPacker(new FileOutputStream(tempFile)); packer.packInt(42); packer.packString("Hello"); packer.close(); FileInputStream in = new FileInputStream(tempFile); ObjectMapper objectMapper = new ObjectMapper(new MessagePackFactory()); objectMapper.configure(JsonParser.Feature.AUTO_CLOSE_SOURCE, false); System.out.println(objectMapper.readValue(in, Integer.class)); System.out.println(objectMapper.readValue(in, String.class)); in.close(); tempFile.deleteOnExit(); } catch (IOException ex) { logger.error("Serialize Error", ex); } } https://www.cwiki.us/display/Serialization/MessagePack+Jackson+Dataformat
