我正在尝试在摇摆应用程序中使用休眠 3.5.1 final，这是我正在使用的罐子：

  • hibernate-core-3.5.1-Final
  • hibernate-entitymanager-3.5.1-Final
  • hibernate-jpa-2.0-api-1.0.0.Final
  • hibernate-annotations-3.5.1-Final
  • hibernate-commons-annotations-3.2.0.Final
  • dom4j-1.6.1
  • slf4j-api-1.6.4
  • slf4j-log4j12-1.6.4

当我尝试运行应用程序时，我收到以下错误：

您还需要在类路径中包含 Log4J JAR 文件。

请注意，这slf4j-log4j12-1.6.4.jar只是一个适配器，可以通过 SLF4J API 使用 Log4J。它不包含 Log4J 的实际实现。

您需要下载log4j并添加到您的类路径中。

在我的环境中，我只是将这两个文件添加到类路径中。并且工作正常。

slf4j-jdk14-1.7.25.jar
slf4j-api-1.7.25.jar
