Spring4-BeanPropertyRowMapper-查询多行

1.创建项目,项目名称(springdemo9),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;

import java.util.List;

import com.mycompany.shequ.bean.Forum;

public interface ForumDao {
public List<Forum> findAll();
}

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 java.util.ArrayList;
import java.util.List;
import java.util.Map;

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 List<Forum> findAll() {
String sql = "select * from hnsq_forum";
List<Forum> forumList = new ArrayList<Forum>();
forumList = getJdbcTemplate().query(sql, new BeanPropertyRowMapper(Forum.class));

return forumList;
}
}

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 java.util.List;

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 testFindAll(){
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

ForumDao forumDao = (ForumDao) context.getBean("forumDao");

List<Forum> forumList = forumDao.findAll();
for(Forum forum : forumList){
System.out.println(forum.getFid() + "_____" + forum.getName());
}

}
}

17.运行测试类中的testFindAll方法,运行结果如图所示
