import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.EntityTransaction;
import javax.persistence.Persistence;

public class TEST {

    public static void main（String[] args） {
        //1. 创建EntityManagerFactory
        String persistenceUnitName = “jpa“; 
        EntityManagerFactory factory = Persistence.createEntityManagerFactory（persistenceUnitName）;

        //2. 创建EntityManager
        EntityManager entityManager = factory.createEntityManager（）;

        //3.开启事务
        EntityTransaction transaction = entityManager.getTransaction（）;
        transaction.begin（）;

        //4. 持久化操作
        User user = new User（）;
        user.setName（“tom2“）;
        user.setEmail（“lamb@qq.com“）;

        //添加user到数据库，相当于hibernate的save（）;
        entityManager.persist（user）;

        //5. 提交事务
        transaction.commit（）;

        //6. 关闭EntityManager
        entityManager.close（）;

        //7. 关闭EntityManagerFactory
        factory.close（）;

    }
