1.创建项目,项目名称(springdemo5),如图所示
2.在项目中创建子目录(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中创建子目录(apache->存储日志记录jar包目录,junit->单元测试jar包目录,mysql->数据库驱动jar包目录,spring->与spring相关的jar包目录),如图所示
4.在lib的子目录(apache->存储日志记录jar包目录,junit->单元测试jar包目录,mysql->数据库驱动jar包目录,spring->与spring相关的jar包目录)中添加相应的jar包,如图所示
5.在src目录中创建实体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下创建接口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 void insert(Forum forum);
}
9.在src中创建接口ForumDao的实现类ForumDaoImpl,包名(com.mycompany.shequ.dao.impl),如图所示
10.接口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.JdbcTemplate;
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 {
private DataSource dataSource;
@Override
public void insert(Forum forum) {
String sql = "INSERT INTO hnsq_forum(name) values(?)";
getJdbcTemplate().update(sql, new Object[]{forum.getName()});
}
}
11.在source目录中创建数据源配置文件spring-datasource.xml,如图所示
12.数据源配置文件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src目录中创建核心配置文件applicationContext.xml,如图所示
14.核心配置文件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目录中创建我们的测试类ForumDaoImplTest,包名(com.mycompany.shequ.dao.impl),如图所示
16.测试类ForumDaoImplTest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 testInsert(){
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
ForumDao forumDao = (ForumDao) context.getBean("forumDao");
Forum forum = new Forum();
forum.setName("demo4");
forumDao.insert(forum);
}
}
17.运行测试方法testInsert,执行结果如图所示
18.查看数据库中的结果,如图所示
