kafka 配置消息编码格式、解决消费者中文乱码

序列化

kafka 发送消息需要把key 和value 进行序列化处理

一般配置字符串方式，如果消息量大需要优化成其他方式。

代码配置

props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");
props.put("serializer.encoding", "UTF-8"); // 设置编码格式
props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
props.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
props.put("deserializer.encoding", "UTF-8"); // 设置编码格式

配置文件配置

spring:
  kafka:
    auto:
      initTopic: false
    bootstrap-servers: *****
    consumer:
      key-deserializer: org.apache.kafka.common.serialization.StringDeserializer
      value-deserializer: org.apache.kafka.common.serialization.StringDeserializer

          jaas:
            config: org.apache.kafka.common.security.plain.PlainLoginModule required username="*****" password="****";
    producer: # 生产者
      retries: 1 # 设置大于0的值，则客户端会将发送失败的记录重新发送
      # 每次批量发送消息的数量
      batch-size: 16384
      buffer-memory: 33554432
      # 指定消息key和消息体的编解码方式
      key-serializer: org.apache.kafka.common.serialization.StringSerializer
      value-serializer: org.apache.kafka.common.serialization.StringSerializer
      properties:
