package com.mycompany.shequ.bean;
public class Forum {
private int fid;
private String name;
public int getFid() {
return fid;
}
public void setFid(int fid) {
this.fid = fid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}7.在src目录创建接口ForumDao,包名(com.mycompany.shequ.dao)如图所示
8.接口ForumDao的内容如下
package com.mycompany.shequ.dao;
import com.mycompany.shequ.bean.Forum;
public interface ForumDao {
public Forum findByForumId(int fid);
}9.在src目录中创建ForumDao的实现类ForumDaoImpl,包名(com.mycompany.shequ.dao.impl),如图所示
10.ForumDao的实现类ForumDaoImpl的内容如下
package com.mycompany.shequ.dao.impl;
import javax.sql.DataSource;
import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.support.JdbcDaoSupport;
import com.mycompany.shequ.bean.Forum;
import com.mycompany.shequ.dao.ForumDao;
public class ForumDaoImpl extends JdbcDaoSupport implements ForumDao {
@Override
public Forum findByForumId(int fid) {
String sql = "select * from hnsq_forum where fid = ?";
Forum forum = (Forum)getJdbcTemplate().queryForObject(sql,
new Object[]{fid},new BeanPropertyRowMapper(Forum.class));
return forum;
}
}11.在source目录中创建配置文件spring-datasource.xml,如图所示
12.配置文件spring-datasource.xml的内容如下
<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-3.0.xsd"> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/b_shequ_two" /> <property name="username" value="root" /> <property name="password" value="" /> </bean> </beans>
13.在source目录中创建配置文件applicationContext.xml,如图所示
14.配置文件applicationContext.xml的内容如下
<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-2.5.xsd"> <import resource="spring-datasource.xml" /> <bean id="forumDao" class="com.mycompany.shequ.dao.impl.ForumDaoImpl"> <property name="dataSource" ref="dataSource" /> </bean> </beans>
15.在test目录中创建ForumDaoImplTest测试类,包名(com.mycompany.shequ.dao.impl),如图所示
16.ForumDaoImplTest测试类的内容如下
package com.mycompany.shequ.dao.impl;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.mycompany.shequ.bean.Forum;
import com.mycompany.shequ.dao.ForumDao;
public class ForumDaoImplTest {
@Test
public void testFindByForumId(){
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
ForumDao forumDao = (ForumDao) context.getBean("forumDao");
Forum forum = forumDao.findByForumId(40);
System.out.println(forum.getName());
}
}17.运行测试类中的testFindByForumId方法,运行结果如图所示
