1：通过maven添加需要的jar包
1 <dependencies> 2 <dependency> 3 <groupId>org.springframework</groupId> 4 <artifactId>spring-web</artifactId> 5 <version>3.2.9.RELEASE</version> 6 </dependency> 7 8 <dependency> 9 <groupId>org.aspectj</groupId> 10 <artifactId>aspectjrt</artifactId> 11 <version>1.8.1</version> 12 </dependency> 13 14 <dependency> 15 <groupId>org.aspectj</groupId> 16 <artifactId>aspectjweaver</artifactId> 17 <version>1.8.1</version> 18 </dependency> 19 20 <dependency> 21 <groupId>mysql</groupId> 22 <artifactId>mysql-connector-java</artifactId> 23 <version>5.1.31</version> 24 </dependency> 25 26 <dependency> 27 <groupId>org.hibernate</groupId> 28 <artifactId>hibernate-core</artifactId> 29 <version>4.2.0.Final</version> 30 </dependency> 31 32 <dependency> 33 <groupId>org.apache.openejb</groupId> 34 <artifactId>commons-dbcp-all</artifactId> 35 <version>1.3</version> 36 </dependency> 37 38 <dependency> 39 <groupId>org.springframework</groupId> 40 <artifactId>spring-orm</artifactId> 41 <version>3.2.9.RELEASE</version> 42 </dependency> 43 </dependencies>
2：配置实体类与数据库关联
1 @Entity
2 @Table(name="user")
3 public class User {
4 @Id
5 @GenericGenerator(name="native",strategy="native")
6 @GeneratedValue(generator="native")
7 private int id;
8
9 @Column(name="username")
10 private String name;
11 }
3：dao
1 public interface UserDao {
2 public User findUserById(int id);
3 }
4
5 @Repository
6 public class UserDaoImpl implements UserDao {
7 @Autowired
8 private SessionFactory sessionFactory;
9
10 public User findUserById(int id) {
11 Session session = sessionFactory.openSession();
12 Transaction ts = session.beginTransaction();
13
14 User user = (User)session.get(User.class, id);
15 session.delete(user);
16
17 ts.commit();
18 session.close();
19 return user;
20 }
21 }
4：service
1 public interface UserService {
2 public User getUserById(int id);
3 }
4
5 @Service
6 public class UserServiceImpl implements UserService {
7 @Autowired
8 private UserDao userDao;
9
10 public User getUserById(int id) {
11 return userDao.findUserById(id);
12 }
13 }
5：测试代码
1 @Component("client")
2 public class Client {
3 @Autowired
4 private UserService userService;
5
6 public static void main(String[] args) {
7 ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
8
9 Client st = (Client)ac.getBean("client");
10 UserService userService = st.userService;
11 User user = userService.getUserById(1);
12
13 System.out.println(user.getName());
14 }
15 }
6：配置文件applicationContext.xml
1 <?xml version="1.0" encoding="UTF-8"?>

7：数据库连接池配置dbcp.properties
url=jdbc:mysql://localhost:3306/test driverClassName=com.mysql.jdbc.Driver mysqlusername=root mysqlpassword=root maxActive=8 minIdle=3 maxIdle=8 maxWait=40000 initialSize=2 logAbandoned=true removeAbandoned=true removeAbandonedTimeout=30 timeBetweenEvictionRunsMillis=10000 numTestsPerEvictionRun=8
