我在这里使用了debezium.io提供的教程，并将其调整为使用mssqlserver数据库而不是mysql，但是当我在数据库中进行更改时，watcher不会显示任何事件或活动。以下是我采取的步骤：
我运行了zookeeper docker命令： docker run -it --rm --name zookeeper -p 2181:2181 -p 2888:2888 -p 3888:3888 debezium/zookeeper:1.1 然后我运行了kafka docker命令： docker run -it --rm --name kafka -p 9092:9092 --link zookeeper:zookeeper debezium/kafka:1.1 然后我运行了一个启用代理的sql server docker命令： docker run -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=yourStrong(!)Password' -e 'MSSQL_AGENT_ENABLED=True' --name mssql -p 1433:1433 -d mcr.microsoft.com/mssql/server:2019-latest 然后我连接到sql server示例，创建了一个名为peopledb的数据库，并通过运行以下查询创建了一个名为people的表：
USE [PeopleDb] GO CREATE TABLE [dbo].[People]([Id] [bigint] IDENTITY(1,1) NOT NULL,[FirstName] [varchar](50) NOT NULL, [LastName] [varchar](50) NOT NULL, CONSTRAINT [PK_People] PRIMARY KEY CLUSTERED ( [Id] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY] GO 然后我运行以下命令来启用cdc：
Use PeopleDb Go EXEC sys.sp_cdc_enable_db EXEC sys.sp_cdc_enable_table @source_schema = N'dbo', @source_name = N'People', @role_name = Null, @filegroup_name = N'Primary',@supports_net_changes = 0 EXEC sys.sp_cdc_help_change_data_capture 我注意到cdc表是在“系统表”下创建的。当我运行下面的查询时，一条记录被添加到cdc.dbo\u people\u ct表中： INSERT INTO TABLE dbo.People(FirstName, LastName) values ('John', 'Smith') 然后我运行connector docker命令： docker run -it --rm --name connect -p 8083:8083 -e GROUP_ID=1 -e CONFIG_STORAGE_TOPIC=my_connect_configs -e OFFSET_STORAGE_TOPIC=my_connect_offsets -e STATUS_STORAGE_TOPIC=my_connect_statuses --link zookeeper:zookeeper --link kafka:kafka --link mssql:mssql debezium/connect:1.1 然后我通过将下面的json发布到http://localhost：8083/连接器/：

{
       "name": "people-connector",
       "config": {
           "connector.class": "io.debezium.connector.sqlserver.SqlServerConnector",
           "tasks.max": "1",
           "database.hostname": "mssql",
           "database.port": "1433",
           "database.user": "sa",
           "database.password": "yourStrong(!)Password",
           "database.dbname": "PeopleDb",
           "database.server.id": "184054",
           "database.server.name": "mssql",
           "database.history.kafka.bootstrap.servers": "kafka:9092",
           "database.history.kafka.topic": "mssql.dbo.people",
           "name": "people-connector"
       },
       "tasks": [],
       "type": "source"
   }

我通过检查来验证新添加的连接器是否正在运行http://localhost：8083/连接器/人员连接器/状态： {"name":"people-connector","connector":{"state":"RUNNING","worker_id":"172.17.0.5:8083"},"tasks":[{"id":0,"state":"RUNNING","worker_id":"172.17.0.5:8083"}],"type":"source"} 我运行了watcher docker命令： docker run -it --rm --name watcher --link zookeeper:zookeeper --link kafka:kafka debezium/kafka:1.1 watch-topic -a -k mssql.dbo.people 结果如下：

        "autoIncremented" : false,
        "generated" : false
      } ]
    }
  } ]
}

完成这些步骤并确保有一个正在运行的连接器之后，我希望在将新记录插入people表或删除或更新它们时看到新的事件，但是观察者没有显示任何活动。有人知道为什么debezium和sqlserver之间似乎存在断开连接吗？
