Actual behaviour

If there is an exception, please attach the exception trace:
2019-06-09 16:12:15.776 [pool-4-thread-1] INFO c.a.otter.canal.client.adapter.rdb.support.BatchExecutor - 当前的类型为:12=====>当前的数据为:1810265
2019-06-09 16:12:15.795 [pool-10-thread-1] ERROR c.a.o.canal.adapter.launcher.loader.CanalAdapterWorker - java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.lang.NumberFormatException: For input string: "张红"
java.lang.RuntimeException: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.lang.NumberFormatException: For input string: "张红"

1810265 的字段类型应该是4 int类型但是这边会对应成 12 ，张红就是varchar，但是应该对应成了int

Just put your stack trace here!
