java - 当我尝试通过套接字流发送/接收 jxrpc 时出现 "socket closed"错误

Question

这是我的代码:

ObjectMapper mapper = new ObjectMapper();
mapper.configure(JsonParser.Feature.AUTO_CLOSE_SOURCE, false);//suggested by fge

Socket s = new Socket("127.0.0.1",port);
mapper.writeValue(s.getOutputStream(),anObjectRequest);//this works
Aresponse res = mapper.readValue(s.getInputStream(),AresponseClass.class);

我知道套接字已关闭。

但是，如果查看wireshark，我发现服务器正确接收请求并正确发送答案! 问题出在哪里？

Answer 1

http://docs.oracle.com/javase/7/docs/api/java/net/Socket.html#getOutputStream()

Closing the returned OutputStream will close the associated socket

映射器是什么类型？此方法是否:

mapper.writeValue(s.getOutputStream(),anObjectRequest);//this works

对 OutputStream 对象调用 close？

假设您使用的是 ObjectMapper :

Note: method does not close the underlying stream explicitly here; however, JsonFactory this mapper uses may choose to close the stream depending on its settings (by default, it will try to close it when JsonGenerator we construct is closed).

您必须注意您正在使用哪个 JsonFactory。
