Netty TCP服务器字符变成垃圾

Question

我已经分配在我的组织中执行TCP服务器以接收文本消息并将其拆分。但不幸的是我的一些 消息字符变成垃圾（我已经使用JMeter作为我的TCP客户端）。我有2个与此问题相关的问题。任何帮助都非常感谢。

  

  

1. 为什么我们不能使用“»”（u00BB）字符拆分我的信息？它从来没有用过，我们如何在DelimiterBasedFrameDecoder中使用“»”作为分隔符？

  

2. 为什么我们收到垃圾字符虽然我在编码/解码中使用了UTF-8？ （仅在我评论"pipeline.addLast("frameDecoder", new io.netty.handler.codec.DelimiterBasedFrameDecoder( 500000, byteDeli)"）

时设法接收消息

Answer 1

发现问题并且与netty无关。错误是使用JMeter编码。设法在修改＆＃34; jmeter.properties＆＃34;之后解决了这个问题。属性文件@ \ apache-jmeter-x.xx \ bin。

tcp.charset=UTF-8

很抱歉给你们带来麻烦，因为对我不好。
