无效的UTF-8中间字节0x72 [英] Invalid UTF-8 middle byte 0x72

问题描述

我在spring-kafka中使用JsonSerializer和JsonDeserializer设置值序列化器，同时生成一条消息. 邮件中的一个字段(orgName)带有特殊字符(德语为umlaut).如何处理此特殊字符?我知道JsonDeserializer使用jackson，而jackson支持utf-8. JsonDeserializer会因此引发此错误:

I am using JsonSerializer and JsonDeserializer in spring-kafka to set the value serializer while producing a message. The message has one field(orgName)with a special character in it (german umlaut).How do I handle this special character? I know JsonDeserializer uses jackson and jackson supports utf-8. The JsonDeserializer throws this error because of it:

推荐答案

确保使用-Dfile.encoding = UTF-8启动JVM.您的JVM默认为操作系统字符集

Make sure to start you JVM with -Dfile.encoding=UTF-8. You JVM defaults to the operating system charset

这是我的教程为此！
