SLF4J: Class path contains multiple SLF4J bindings.

[Galthen]

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/chenyang/Documents/lib/flink-jdbc-driver-0.1-SNAPSHOT.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/Users/chenyang/.m2/repository/ch/qos/logback/logback-classic/1.1.11/logback-classic-1.1.11.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.slf4j.helpers.NOPLoggerFactory]

The StaticLoggerBinder in flink-jdbc-driver will conflict with logback-classic. If the dependency on logback-classic is excluded, springboot will not enter the log.
