项目环境：
spring4.1.6
hibernate4.3.11
spring-data-jpa1.9.0
1. 创建一个Java Project，将jar导入到lib目录下
#spring
spring-aop-4.1.6.RELEASE.jar
spring-aspects-4.1.6.RELEASE.jar
spring-beans-4.1.6.RELEASE.jar
spring-context-4.1.6.RELEASE.jar

mchange-commons-java-0.2.3.4.jar #mysql
mysql-connector-java-5.1.25.jar #commons-logging
commons-logging-1.2.jar
2. 添加配置文件
(1) 在classpath下创建jdbc.properties
jdbc.url=jdbc:mysql://192.168.178.5:12345/ssm?useUnicode=true&characterEncoding=UTF-8
jdbc.driver.class=com.mysql.jdbc.Driver
jdbc.username=root
jdbc.password=123456
(2) 在classpath下创建applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>

<!-- base-package：扫描 dao 接口所在的包 -->
<jpa:repositories base-package="com.linhw.demo.dao" /> </beans>
3. 编写实体类
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table; @Entity
@Table(name="user")
public class User {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)//strategy=GenerationType.IDENTITY 自增长
@Column(name="user_id")
private Integer userId;
@Column(name="user_name")
private String userName;
@Column(name="age")
private Integer age; public User() {
}
public User(Integer userId, String userName, Integer age) {
this.userId = userId;
this.userName = userName;
this.age = age;
}
public Integer getUserId() {
return userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
@Override
public String toString() {
return "User [userId=" + userId + ", userName=" + userName + ", age=" + age + "]";
}
}
4. 编写Dao
public interface UserDao extends JpaRepository<User, Integer>{
}5. 编写测试方法
//@RunWith是org.junit.runner.RunWith
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class UserDaoTest { @Autowired
private UserDao userDao; @Test
public void testSaveUser(){
User user = new User();
user.setUserName("zhangsan");
user.setAge(29);
userDao.save(user);
} }
