我正在使用以下依赖项，

        <dependency>
        <groupId>io.debezium</groupId>
        <artifactId>debezium-connector-oracle</artifactId>
        <version>${version.debezium}</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/io.debezium/debezium-connector-mysql -->
    <dependency>
        <groupId>io.debezium</groupId>
        <artifactId>debezium-connector-mysql</artifactId>
        <version>${version.debezium}</version>
    </dependency>

<version.debezium>0.8.3.Final</version.debezium>

下面是我的java方法，

public void runMysqlParsser() {

    Configuration config = Configuration.create()
            /* begin engine properties */
            .with("connector.class",
                    "io.debezium.connector.mysql.MySqlConnector")
            .with("offset.storage",
                    "org.apache.kafka.connect.storage.FileOffsetBackingStore")
            .with("offset.storage.file.filename",
                    "/home/mohit/tmp/offset.dat")
            .with("offset.flush.interval.ms", 60000)
            /* begin connector properties */
            .with("name", "my-sql-connector")
            .with("database.hostname", "localhost")
            .with("database.port", 3306)
            .with("database.user", "root")
            .with("database.password", "root")
            .with("server.id", 1)
            .with("database.server.name", "my-app-connector")
            .with("database.history",
                    "io.debezium.relational.history.FileDatabaseHistory")
            .with("database.history.file.filename",
                    "/home/mohit/tmp/dbhistory.dat")
            .with("database.whitelist", "mysql")
            .with("table.whitelist", "mysql.customers")
            .build();
    EmbeddedEngine engine = EmbeddedEngine.create()
            .using(config)
            .notifying(this::handleEvent)
            .build();
    Executor executor = Executors.newSingleThreadExecutor();
    executor.execute(engine);
}

    private void handleEvent(SourceRecord sourceRecord) {
    try {
        LOG.info("Got record :" + sourceRecord.toString());
    } catch (Exception ex) {
        LOG.info("exception in handle event:" + ex);
    }

我的 sql 配置，.

general_log_file = /var/log/mysql/mysql.log
general_log = 1
server-id               = 1
log_bin                 = /var/log/mysql/mysql-bin.log
expire_logs_days        = 10
max_binlog_size   = 100M
binlog_format     = row
binlog_row_image  = full
binlog_rows_query_log_events = on
gtid_mode        =  on
enforce_gtid_consistency   = on

当我运行这段代码时，我得到了历史日志的偏移量，mysql.log 文件也得到了添加到它的偏移量。但是，当我对表执行任何更新语句时，它没有给我任何日志，即没有调用 handleEvent 方法。谁能告诉我代码或配置有什么问题？

下面是运行java代码后的日志，

您是否将正确的数据库/表列入白名单？

您能否看一下这个演示 - https://github.com/debezium/debezium-examples/tree/master/kinesis 只需删除 Kinesis 相关代码并仅打印到控制台即可。还要检查table.ignore.builtin配置选项。恕我直言mysql，数据库属于内置数据库，默认情况下被过滤掉。
