javax.persistence:persistence-api:1.0.2是2007年7月24日 。

我將使用javax.persistence:javax.persistence-api:2.2 ，而不是2017年8月21日 。

順便說一下，你為什么要在POM中兩次聲明maven-compiler-plugin ？ 這導致了警告：

[WARNING] 'build.plugins.plugin.(groupId:artifactId)' must be unique but found duplicate declaration of plugin org.apache.maven.plugins:maven-compiler-plugin @ line 27, column 15

這也不好：

[WARNING] Using platform encoding (Cp1252 actually) to copy filtered resources, ie build is platform dependent!

我在IDE中將編碼更改為UTF-8並使用POM屬性 ： 

  <properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
  </properties>

這樣你可以完全放棄這些maven-compiler-plugin聲明，因為編譯器使用所有這些屬性：compile和site：site默認情況下。
