This is the one for javax.persistence :

<dependency>
   <groupId>javax.persistence</groupId>
   <artifactId>persistence-api</artifactId>
   <version>1.0.2</version>
   <scope>provided</scope>
</dependency>

and this is for the whole Java EE 6 stack:

<dependency>
   <groupId>javax</groupId>
   <artifactId>javaee-api</artifactId>
   <version>6.0</version>
   <scope>provided</scope>
</dependency>

Edit

Note that I specified a provided scope here, which means that your dependency is available at compile- and test-time, but will not be packaged into your artifacts. This is usually needed if you want to deploy your artifacts in an application server, since they provide their own implementation of the api.

And add this dependency in your pom.xml :

<dependency>
    <groupId>javax.persistence</groupId>
    <artifactId>persistence-api</artifactId>
    <version>1.0.2</version>
</dependency>

That "Coping with Sun JARs" page might be a little outdated, this JAR is available in the Maven Central Repository

更新链接：https://mvnrepository.com/artifact/javax.persistence/javax.persistence-api/2.2在这里。
Maven依赖关系如下：

<dependency>
            <groupId>javax.persistence</groupId>
            <artifactId>javax.persistence-api</artifactId>
