首先,我们需要安装mysql数据库,并下载相应的驱动包 库脚本如下: CREATE TABLE `test` ( `testid` varchar(10) default NULL, `testname` varchar(10) default NULL) ENGINE=InnoDB DEFAULT CHARSET=gb2312;表中数据为:1 name12 name23 name34 name45 name5 DAO接口 package ch8.jdbcTemplage;import java.util.List;public interface ITestDAO ...{ public List getAll();} 对应数据表的JavaBean package ch8.jdbcTemplage;public class User ...{ private String name; private String id;public User(String name, String id) ...{ this.name = name; this.id = id;}public String getId() ...{ return id;}public void setId(String id) ...{ this.id = id;}public String getName() ...{ return name;}public void setName(String name) ...{ this.name = name;}public String toString() ...{ return this.id+"--"+this.name;}} DAO实现 package ch8.jdbcTemplage;import java.sql.Connection;import java.sql.PreparedStatement;import java.sql.ResultSet;import java.sql.SQLException;import java.util.ArrayList;import java.util.List;import org.springframework.dao.DataAccessException;import org.springframework.jdbc.core.PreparedStatementCallback;import org.springframework.jdbc.core.PreparedStatementCreator;import org.springframework.jdbc.core.support.JdbcDaoSupport;public class TestDAOImpl extends JdbcDaoSupport implements ITestDAO ...{ public List getAll() ...{ return (List)this.getJdbcTemplate().execute( new PreparedStatementCreator()...{ public PreparedStatement createPreparedStatement(Connection connection) throws SQLException...{ return connection.prepareStatement("select * from test"); } },new PreparedStatementCallback()...{ public Object doInPreparedStatement(PreparedStatement ps) throws SQLException,DataAccessException...{ List result=new ArrayList(); ResultSet rs=ps.executeQuery(); User t=null; while(rs.next())...{ t=new User(rs.getString("testid"),rs.getString("testname")); result.add(t); } return result; } } ); }} 配置文件: <?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName"> <value>com.mysql.jdbc.Driver</value> </property> <property name="username"> <value>root</value> </property> <property name="password"> <value>1234</value> </property> <property name="url"> <value>jdbc:mysql://localhost:3306/spring</value> </property></bean><bean id="testDAO" class="ch8.jdbcTemplage.TestDAOImpl"> <property name="dataSource"> <ref bean="dataSource"/> </property></bean></beans> 测试代码: package ch8.jdbcTemplage;import java.util.Iterator;import java.util.List;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Test ...{ /** *//** * @param args */ public static void main(String[] args) ...{ ApplicationContext context=new ClassPathXmlApplicationContext("ch8/jdbcTemplage/applicationContext.xml"); TestDAOImpl testDAOImpl=(TestDAOImpl)context.getBean("testDAO"); List result=testDAOImpl.getAll(); for (Iterator iter = result.iterator(); iter.hasNext();) ...{ User element = (User) iter.next(); System.out.println(element); } }}
