Question

当我运行mvn hibernate3：hbm2cfgxml时，它不会生成hibernate.cfg.xml文件。但是它会生成pojos和daos，但不会生成hibernate.cfg.xml文件。

以下是我的pom.xml。

需要在pom.xml中添加什么才能生成hibernate.cfg.xml文件。

Answer 1

基于documentation，您需要创建如下所示的部分：

<component>
  <name>hbm2cfgxml</name>
  <implementation>...</implementation>
  ...
</component>

Answer 2

此外，除了上述答案，我认为你的POM中有“hbm2ddl”组件的重复声明。

您可以参考： http://hop2croft.wordpress.com/2011/05/08/creating-java-domain-objects-with-the-maven-hibernate-plugin/#highlighter_819265 和 https://forum.hibernate.org/viewtopic.php?f=6&t=1008209&view=previous

即使我运行mvn hibernate3，hibernate.cfg.xml也没有被创建：hbm2cfgxml
