你好，
我正在尝试用 Hibernate 和 Maven 做一个简单的应用程序。
我创建了hibernate.cfg.xml 和映射文件contacts.hbm.xml。
一旦我开始它，我就会得到一个例外：
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

什么可能是该异常的来源？
如果需要，可以发布 PS Java 类。

这对我有帮助
And finally it looks like there's a problem with contacts.hbm.xml. Change
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
to
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
