1.1.6版本中升级了fastjson2之后，CanalRabbitMQConsumer中使用JSO

// json中带null的会报错, 比如这个ALTER语句产生的消息 String messageData = "{"data":null,"database":"canal-test-to1","es":1654937242000,"id":153,"isDdl":true,"mysqlType":null,"old":null,"pkNames":null,"sql":"ALTER TABLE canal-test-to1.test_table1 ADD COLUMN birthday date NULL","sqlType":null,"table":"test_table1","ts":1654937242664,"type":"ALTER"}"; CommonMessage commonMessage = JSON.parseObject(messageData, CommonMessage.class); System.out.println(commonMessage);

异常栈信息

Exception in thread "main" com.alibaba.fastjson2.JSONException: json format error : n at com.alibaba.fastjson2.reader.FieldReaderListStrMethod.readFieldValue(FieldReaderListStrMethod.java:83) at com.alibaba.fastjson2.reader.ObjectReaderBean.readObject(ObjectReaderBean.java:174) at com.alibaba.fastjson2.JSON.parseObject(JSON.java:258)

// 把null去掉就没问题 String messageData = "{"database":"canal-test-to1","es":1654937242000,"id":153,"isDdl":true,"sql":"ALTER TABLE canal-test-to1.test_table1 ADD COLUMN birthday date NULL","table":"test_table1","ts":1654937242664,"type":"ALTER"}"; CommonMessage commonMessage = JSON.parseObject(messageData, CommonMessage.class); System.out.println(commonMessage);

换成旧版本的fastjson上面的代码都没问题
