1.pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2.在src/main/resources目录下包含两个文件

2.1 src/main/resources/META-INF/persistence.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.jin.jpa</groupId>
  <artifactId>jpamaven</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>jar</packaging>

  <name>jpamaven</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.hibernate.version>4.1.7.Final</project.hibernate.version>    
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
    <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-entitymanager</artifactId>
            <version>${project.hibernate.version}</version>
        </dependency>
        
        <!-- connection pooling with c3p0 -->
        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-c3p0</artifactId>
            <version>${project.hibernate.version}</version>
        </dependency>
        
        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.17</version>
        </dependency>

        <!-- Mysql and MariaDB -->
         <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>

        </dependency>
        
  </dependencies>
</project>

3.写一个bean来测试这个环境

src/main/java/com/jin/beans/Person.java

 1 package com.jin.beans;
 2 
 3 import javax.persistence.Entity;
 4 import javax.persistence.GeneratedValue;
 5 import javax.persistence.Id;
 6 
 7 @Entity
 8 public class Person {
 9 
10     @Id @GeneratedValue
11     private Integer id;
12     private String name;
13     public Integer getId() {
14         return id;
15     }
16     public void setId(Integer id) {
17         this.id = id;
18     }
19     public String getName() {
20         return name;
21     }
22     public void setName(String name) {
23         this.name = name;
24     }
25     public Person(String name) {
26         super();
27         this.name = name;
28     }
29     public Person() {
30         super();
31         // TODO Auto-generated constructor stub
32     }
33     @Override
34     public String toString() {
35         return "Person [id=" + id + ", name=" + name + "]";
36     }
37     
38 }

4.测试

src/test/java/com/jin/jpa/PersonTest.java

 1 public class PersonTest {
 2 
 3     @Test
 4     public void save() {
 5         EntityManagerFactory factory = Persistence.createEntityManagerFactory("persistence-unit_demo");
 6         EntityManager manager = factory.createEntityManager();
 7         manager.getTransaction().begin();
 8         manager.persist(new Person("小天天"));
 9         manager.getTransaction().commit();
10         manager.close();
11         factory.close();
12     }
13     
14 }
