Hi, 用的 flink 版本是多少？ 数据库的字段确定是 bigint 类型吗？ > Caused by: java.lang.ClassCastException: java.math.BigInteger cannot be cast > to java.lang.Long
java.math.BigInteger 的范围比 java.lang.Long的范围大很多，是不能cast的，应该是你数据类型对应错误了，可以把mysql 表的schema贴下吗？ 祝好， Leonard Xu > 在 2020年6月11日，13:22，Zhou Zach <[email protected]> 写道： > > SLF4J: Class path contains multiple SLF4J bindings. > > SLF4J: Found binding in > [jar:file:/Users/Zach/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.4.1/log4j-slf4j-impl-2.4.1.jar!/org/slf4j/impl/StaticLoggerBinder.class] > > SLF4J: Found binding in > [jar:file:/Users/Zach/.m2/repository/org/slf4j/slf4j-log4j12/1.7.7/slf4j-log4j12-1.7.7.jar!/org/slf4j/impl/StaticLoggerBinder.class] > > SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an > explanation. > > SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory] > > ERROR StatusLogger No log4j2 configuration file found.
