本文介绍了Thrift无法从json反序列化为java对象的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我从以下thrift对象生成了一个java对象:
I generated a java object from the following thrift object:
struct Account {
1: required string accountType,
2: bool accountActive,
}
我写了一个试用的java代码将java对象序列化为json字符串,然后将json字符串反序列化为java对象。我可以成功序列化但无法反序列化。
I wrote a java code trying to serialize java object to json string and then deserialize the json string back to java object. I can serialize successfully but failed to deserialize.
TSerializer serializer = new TSerializer(new TSimpleJSONProtocol.Factory());
TDeserializer deserializer = new TDeserializer(new TSimpleJSONProtocol.Factory());
Account a1 = new Account();
a1.setAccountType("P");
a1.setAccountActive(true);
String json = serializer.toString(a1);
System.out.println(json);
Account a2 = new Account();
deserializer.deserialize(a2, json, "UTF-8");
System.out.println(a2);
System.out.println(a2.getAccountType());
它一直抛出以下异常:
Exception in thread "main" org.apache.thrift.protocol.TProtocolException: Required field 'accountType' was not present! Struct: Account(accountType:null, accountActive:false)
任何人都可以帮我弄清问题是什么?
提前致谢!
Can anyone help me figure out what's the issue?Thanks in advance!
推荐答案
SimpleJSONProtocol
从未旨在可以反序列化。改为使用 TJSONProtocol
。
The SimpleJSONProtocol
was never intended to be deserializable. Use TJSONProtocol
instead.
来自:
TSerializer serializer = new TSerializer(new TSimpleJSONProtocol.Factory());
String json = serializer.toString(work);
简单JSON协议产生适合AJAX或脚本语言的输出。它不保留Thrift的字段标签,也不能通过Thrift读回。
