Spring Kafka Connect如何使命名空间与数据库名称无关

我的环境

MySQL（5.7）：我们有多个模式，命名约定是{application\u name}\u env

示例：考虑我们有两个应用程序：APP1和APP2

Dev环境：数据库名称为app1\u Dev、app2\u Dev

QA环境：数据库名称为app1_QA、app2_QA

脱苄（0.8.3）。该插件用于CDC MySQL日志

连接器配置为：

{
"name": "connector-1",
"config": {
    "connector.class": "io.debezium.connector.mysql.MySqlConnector",
    "tasks.max": "1",
    "database.hostname": "mysql",
    "database.port": "3306",
    "database.user": "debezium",
    "database.password": "dbz",
    "database.server.id": "184054",
    "database.server.name": "dbserver1",
    "database.history.kafka.bootstrap.servers": "kafka:9092",
    "database.history.kafka.topic": "schema-changes.inventory",
    "decimal.handling.mode": "double",
    "snapshot.mode": "when_needed",
    "table.whitelist":"{database_name}.account",
    "key.converter": "io.confluent.connect.avro.AvroConverter",
    "value.converter": "io.confluent.connect.avro.AvroConverter",
    "key.converter.schema.registry.url": "http://schema-registry:8081",
    "value.converter.schema.registry.url": "http://schema-registry:8081",
    "transforms" : "setSchema",
    "transforms.setSchema.type" : "org.apache.kafka.connect.transforms.SetSchemaMetadata$Value",
    "transforms.setSchema.schema.name" : "com.test.Account"
}

}

Spring Java应用程序我正在使用Kafka Consumer（@KafkaListener）读取Debezium事件中的更改

我提供了avsc文件，并使用gradle avro插件生成类

问题： 因为我的数据库模式是动态的，即它们以env后缀结尾

在每个环境中生成的架构具有不同的命名空间

Dev:Dev.app1u Dev.accounts QA:dev.app1u QA.accounts

由于名称空间不同，我无法在QA中反序列化我的开发代码。因此，如果使用在Dev中生成的模式，代码将无法在QA中工作

---

我想确保名称空间在所有环境中都是一致的。

请使用

org.apache.kafka.connect.transforms.SetSchemaMetadata

SMT-请参见请使用

org.apache.kafka.connect.transforms.SetSchemaMetadata

SMT-请参见我已经在使用的：）问题是嵌套级别的，名称空间不是正在更改。我已经在使用：）问题是在嵌套级别，命名空间没有更改。您能解决这个问题吗？如果您有，我将非常感谢您的指导。谢谢你能解决这个问题吗？如果您有，我将非常感谢您的指导。谢谢
