Try the Geronimo specs JPA2 jar http://mirrors.ibiblio.org/pub/mirrors/maven2/org/apache/geronimo/specs/geronimo-jpa_2.0_spec/1.0-PFD2/There is still no official JPA2.jar
试试 Geronimo 规范 JPA2 jar http://mirrors.ibiblio.org/pub/mirrors/maven2/org/apache/geronimo/specs/geronimo-jpa_2.0_spec/1.0-PFD2/仍然没有官方的 JPA2.jar

EclipseLink provides the JPA 2.0 Reference Implementation which is officially out since Java EE 6 is out. You'll find these classes in the jars bundled in eclipselink-2.0.0.v20091127-r5931.zip. If you are looking for a Maven repo, have a look at this page.
EclipseLink 提供了 JPA 2.0 参考实现，它在 Java EE 6 发布后正式发布。您将在eclipselink-2.0.0.v20091127-r5931.zip 中捆绑的 jars 中找到这些类。如果您正在寻找 Maven 存储库，请查看此页面。

A slightly better answer (since 2011) is to use the one from maven central, i.e.,
一个稍微好一点的答案（自 2011 年以来）是使用 maven central 中的一个，即，
org.hibernate.javax.persistence:hibernate-jpa-2.0-api:1.0.1-Final
OR
或者
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
<version>1.0.1.Final</version>
See: http://repo1.maven.org/maven2/org/hibernate/javax/persistence/hibernate-jpa-2.0-api/1.0.1.Final/
见：http: //repo1.maven.org/maven2/org/hibernate/javax/persistence/hibernate-jpa-2.0-api/1.0.1.Final/
For all the available versions, especially the latest, see http://repo1.maven.org/maven2/org/hibernate/javax/persistence/hibernate-jpa-2.0-api/
有关所有可用版本，尤其是最新版本，请参阅http://repo1.maven.org/maven2/org/hibernate/javax/persistence/hibernate-jpa-2.0-api/

These files are found in the javax.persistencejar file. The Eclipse version of the javax.persistencejar file can be found on Maven Central. Or you can add the following dependency in your project's pom.xmlfile to get Maven to pull it down for you.
这些文件位于javax.persistencejar 文件中。可以在Maven Central上找到javax.persistencejar 文件的 Eclipse 版本。或者，您可以在项目文件中添加以下依赖项，让 Maven 为您下拉。pom.xml
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>javax.persistence</artifactId>
<version>2.1.1</version>
<scope>compile</scope>
</dependency>
