No factory implements ‘org.apache.flink.table.factories.DeserializationSchemaFactory‘

flink1.12.7 执行java代码，报如下错误：

Caused by: org.apache.flink.table.api.NoMatchingTableFactoryException: Could not find a suitable table factory for 'org.apache.flink.table.factories.DeserializationSchemaFactory' in
the classpath.

Reason: No factory implements 'org.apache.flink.table.factories.DeserializationSchemaFactory'.

最后确认是因为下面的format.type设置成了json。

tableEnv.executeSql("create table source_sensor(account_id  BIGINT)" +
                "with (" +
                "'connector.type' = 'kafka'," +
                "'connector.version' = 'universal'," +
                "'connector.topic' = 'testtopic'," +
                "'connector.properties.bootstrap.servers' = '11.0.24.216:9092'," +
                "'connector.properties.group.id' = 'bigdata1109'," +
                "'format.type' = 'json'"
                + ")");

需要引入flink-json包就可以了：

        
            org.apache.flink
            flink-json
            ${flink.version}
            test
