安装 canal，已经写好了配置文件，结果一直提示空指针
在 CentOS 7.9 下面使用 docker-compose 的方式安装 canal-server 1.1.4，并将消息推送到 kafka，结果 kafka 没有接收到任何消息，查看 canal.log，提示空指针异常。

docker-compose.yml
version: '3.1' services: canal-server: image: canal/canal-server:v1.1.4 container_name: canal-server restart: always ports: - 11111:11111 volumes: - ./conf/canal.properties:/home/admin/canal-server/conf/canal.properties - ./conf/test/instance.properties:/home/admin/canal-server/conf/test/instance.properties - ./logs/:/home/admin/canal-server/logs/
canal.properties
tcp, kafka, RocketMQ 这里选择kafka模式
canal.serverMode = kafka
解析器的线程数，打开此配置，不打开则会出现阻塞或者不进行解析的情况
canal.instance.parser.parallelThreadSize = 16
配置MQ的服务地址，这里配置的是kafka对应的地址和端口
canal.mq.servers = 127.0.0.1:9092
配置instance，在conf目录下要有test同名的目录，可以配置多个
canal.destinations = test
instance.properties
mysql serverId , v1.0.26+ will autoGen(自动生成，不需配置)
canal.instance.mysql.slaveId=0
position info
canal.instance.master.address=127.0.0.1:3306
在Mysql执行 SHOW MASTER STATUS;查看当前数据库的binlog
canal.instance.master.journal.name=mysql-bin.000006 canal.instance.master.position=4596
账号密码
canal.instance.dbUsername=canal canal.instance.dbPassword=Canal@123456 canal.instance.connectionCharset = UTF-8 #MQ队列名称 canal.mq.topic=canalTopic #单队列模式的分区下标 canal.mq.partition=0
