java.lang.NoSuchFieldError : name at run time in hibernate project 错误

Question

尝试我的第一个 hibernate (JPA 注释)控制台应用程序。而且我一直在兜圈子，试图理清依赖关系，感觉就像我在飓风中试图 build 一座纸牌屋。另外，我正在使用 maven，我的印象是 maven 应该可以防止这种类型的事情发生。无论如何，这是我得到的错误:

Exception in thread "main" java.lang.NoSuchFieldError: name
    at org.slf4j.impl.Log4jLoggerAdapter.<init>(Log4jLoggerAdapter.java:75)
    at org.slf4j.impl.Log4jLoggerFactory.getLogger(Log4jLoggerFactory.java:75)
    at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:103)

还有我带注释的 bean 类:

如果我能在这方面得到一些帮助，我将永远感激不尽!

hibernate 实体管理器有两个不同的版本依赖关系。这是行不通的。删除其中一个

<dependency>
      <groupId>hibernate</groupId>
      <artifactId>hibernate-entitymanager</artifactId>
      <version>3.4.0.GA</version>
