1.创建项目,项目名称(springdemo10),如图所示

2.在项目中创建目录(src->源码目录,test->测试目录,source->配置文件目录,lib->jar包目录),如图所示

3.在lib中创建相应的jar包目录,主要用于区分jar包.如图所示

4.在lib的相应的jar包目录中添加jar包.如图所示

5.在src目录创建实体Bean Forum,包名(com.mycompany.shequ.bean),如图所示

6.实体Bean Forum的内容如下

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;public interface ForumDao {public String findNameById(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 org.springframework.jdbc.core.support.JdbcDaoSupport;import com.mycompany.shequ.dao.ForumDao;public class ForumDaoImpl extends JdbcDaoSupport implements ForumDao {@Overridepublic String findNameById(int fid) {String sql = "select name from hnsq_forum where fid = ?";String name = (String)getJdbcTemplate().queryForObject(sql, new Object[]{fid},String.class);return name;}
}

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/beanshttp://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/beanshttp://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.dao.ForumDao;public class ForumDaoImplTest {@Testpublic void testFindNameById(){ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");ForumDao forumDao = (ForumDao) context.getBean("forumDao");String name = forumDao.findNameById(30);System.out.println(name);}
}

17.运行测试类中的testFindNameById方法,运行结果如图所示
