1.创建项目,项目名称(springdemo10),如图所示
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 { @Override public 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
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
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 { @Test public 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
