Spring（五）spring整合jdbc

spring中整合了通過jdbc操作數據庫：

User類：

public class User {
	
	private int sid;
	private Date bithday;
	private String gender;
	private String name;
	
	
	
	@Override
	public String toString() {
		return "User [sid=" + sid + ", bithday=" + bithday + ", gender=" + gender + ", name=" + name + "]";
	}
	public int getSid() {
		return sid;
	}
	public void setSid(int sid) {
		this.sid = sid;
	}
	public Date getBithday() {
		return bithday;
	}
	public void setBithday(Date bithday) {
		this.bithday = bithday;
	}
	public String getGender() {
		return gender;
	}
	public void setGender(String gender) {
		this.gender = gender;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}

UserDao接口：

public interface UserDao {
	public void add(User u);
	public void delete(int sid);
	public void update(User u);
	public User getById(int sid);
	public int getTotalCount();
	public List<User> getAll();
}

UserDao實現類UserDaoImpl：

public class UserDaoImpl implements UserDao{

	private JdbcTemplate jdbcTemplate;
	
	@Override
	public void add(User u) {
		String sql = "insert into Lover values(null,?,?,?)";
		jdbcTemplate.update(sql,u.getBithday(),u.getGender(),u.getName());
	}

	@Override
	public void delete(int sid) {
		String sql = "delete from Lover where sid = ?";
		jdbcTemplate.update(sql,sid);
	}

	@Override
	public void update(User u) {
		String sql = "update Lover set bithday=?,gender=?,name=? where sid=?";
		jdbcTemplate.update(sql,u.getBithday(),u.getGender(),u.getName(),u.getSid());
	}

	@Override
	public User getById(int sid) {
		String sql = "select * from Lover where sid = ?";
		return jdbcTemplate.queryForObject(sql,new RowMapper<User>(){
			@Override
			public User mapRow(ResultSet rs, int arg1) throws SQLException {
				User u = new User();
				u.setSid(rs.getInt("sid"));
				u.setBithday(rs.getDate("bithday"));
				u.setGender(rs.getString("gender"));
				u.setName(rs.getString("name"));
				return u;
			}
		},sid);
	}

	@Override
	public int getTotalCount() {
		String sql = "select count(*) from Lover";
		return jdbcTemplate.queryForObject(sql, Integer.class);
	}

	@Override
	public List<User> getAll() {
		String sql = "select * from Lover";
		List<User> list = jdbcTemplate.query(sql,new RowMapper<User>(){
			@Override
			public User mapRow(ResultSet rs, int arg1) throws SQLException {
				User u = new User();
				u.setSid(rs.getInt("sid"));
				u.setBithday(rs.getDate("bithday"));
				u.setGender(rs.getString("gender"));
				u.setName(rs.getString("name"));
				return u;
			}
		});
		return list;
	}

	public JdbcTemplate getJdbcTemplate() {
		return jdbcTemplate;
	}

	public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
		this.jdbcTemplate = jdbcTemplate;
	}

}

spring配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd ">

<!-- 1.將連接池放入spring容器 -->
	<bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="jdbcUrl" value="jdbc:mysql:///changejob"></property>
		<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
		<property name="user" value="root"></property>
		<property name="password" value="root"></property>
	</bean>
<!-- 2.將JDBCTemplate放入spring容器 -->
	<bean name="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
		<property name="dataSource" ref="dataSource"></property>
	</bean>
<!-- 3.將UserDao放入spring容器 -->
	<bean name="userDao" class="com.milan.spring.jdbc.UserDaoImpl">
		<property name="jdbcTemplate" ref="jdbcTemplate"></property>
	</bean>
</beans>

測試類：

@RunWith(SpringJUnit4ClassRunner.class)//創建容器
@ContextConfiguration("classpath:applicationContext-jdbc.xml")//指定配置文件位置
public class JdbcTest {
	
	@Resource(name="userDao")
	private UserDao userDao;
	
	@Test
	public void add(){
		User u = new User();
		u.setBithday(new Date());
		u.setGender("boy");
		u.setName("add User");
		userDao.add(u);
	}
	
	@Test
	public void delete(){
		userDao.delete(4);
	}
	
	@Test
	public void update(){
		User u = new User();
		u.setSid(1);
		u.setName("kaka");
		userDao.update(u);
	}
	@Test
	public void getById(){
		User u = userDao.getById(1);
		System.out.println(u);
	}
	@Test
	public void getTotalCount(){
		System.out.println(userDao.getTotalCount());
	}
	@Test
	public void getAll(){
		System.out.println(userDao.getAll());
	}
}

 擴展之UserDaoImpl繼承JDBCDaoSupport：

public class UserDaoImplByJDBCDaoSupport extends JdbcDaoSupport implements UserDao{

	
	@Override
	public void add(User u) {
		String sql = "insert into Lover values(null,?,?,?)";
		super.getJdbcTemplate().update(sql,u.getBithday(),u.getGender(),u.getName());
	}

	@Override
	public void delete(int sid) {
		String sql = "delete from Lover where sid = ?";
		super.getJdbcTemplate().update(sql,sid);
	}

	@Override
	public void update(User u) {
		String sql = "update Lover set bithday=?,gender=?,name=? where sid=?";
		super.getJdbcTemplate().update(sql,u.getBithday(),u.getGender(),u.getName(),u.getSid());
	}

	@Override
	public User getById(int sid) {
		String sql = "select * from Lover where sid = ?";
		return super.getJdbcTemplate().queryForObject(sql,new RowMapper<User>(){
			@Override
			public User mapRow(ResultSet rs, int arg1) throws SQLException {
				User u = new User();
				u.setSid(rs.getInt("sid"));
				u.setBithday(rs.getDate("bithday"));
				u.setGender(rs.getString("gender"));
				u.setName(rs.getString("name"));
				return u;
			}
		},sid);
	}

	@Override
	public int getTotalCount() {
		String sql = "select count(*) from Lover";
		return super.getJdbcTemplate().queryForObject(sql, Integer.class);
	}

	@Override
	public List<User> getAll() {
		String sql = "select * from Lover";
		List<User> list = super.getJdbcTemplate().query(sql,new RowMapper<User>(){
			@Override
			public User mapRow(ResultSet rs, int arg1) throws SQLException {
				User u = new User();
				u.setSid(rs.getInt("sid"));
				u.setBithday(rs.getDate("bithday"));
				u.setGender(rs.getString("gender"));
				u.setName(rs.getString("name"));
				return u;
			}
		});
		return list;
	}

}
