根据数据源的表写出实体类：

package daniel.jdbctest.bean;

public class Person {
    private int id;
    private String name;
    private String password;
    
    public Person(String n, String p) {
       this.name =n;
       this.password = p;
    }  
    public Person(int Id,String n, String p) {
       this.id = Id;
       this.name =n;
       this.password = p;
    }
    public void setId(int Id)
    {
        this.id = Id;
    }
    public int getId()
    {
        return id;
    }
    public void setName(String name)
    {
        this.name =name;
    }
    public String getName()
    {
        return name;
    }
    public void setPassword(String password)
    {
        this.password = password;
    }
    public String getPassword()
    {
        return password;
    }
}

接口

package daniel.jdbctest.service;
/*
 * 增删改接口方法，获取一个或多个person对像方法
 */
import daniel.jdbctest.bean.Person;
import java.util.List;

public interface PersonService {
    public void save(Person person);
    public void update(Person person);
    public void delete(int personid);
    public Person getPerson(int personid);
    public List<Person> getPersons();
}

根据接口创建实现类

package daniel.jdbctest.service.impl;


import daniel.jdbctest.bean.Person;
import daniel.jdbctest.service.PersonService;
import java.util.List;
import javax.sql.DataSource;
import org.springframework.jdbc.core.JdbcTemplate;

public class PersonServiceImpl implements  PersonService{
    private JdbcTemplate jdbcTemplate ;
    public void setDataSource(DataSource dataSource)
    {
        this.jdbcTemplate = new JdbcTemplate(dataSource);
    }
    public void save(Person person) {
        jdbcTemplate.update("insert into person(id,name,password) values(?,?,?)", new Object[]{person.getId(),person.getName(),person.getPassword()},
                new int[]{java.sql.Types.INTEGER,java.sql.Types.VARCHAR,java.sql.Types.VARCHAR});
    }//参数1:sql语句，参数2：对应？的具体的值，参数3：值的类型

    public void update(Person person) {
        jdbcTemplate.update("update person set name=? where id=?",new Object[]{person.getName(),person.getId()},
                new int[]{java.sql.Types.VARCHAR,java.sql.Types.INTEGER});
         jdbcTemplate.update("update person set password=? where id=?",new Object[]{person.getPassword(),person.getId()},
                new int[]{java.sql.Types.VARCHAR,java.sql.Types.INTEGER});
    }参数1:sql语句，参数2：对应？的具体的值，参数3：值的类型

    public void delete(int personid) {
        jdbcTemplate.update("delete from person where id =?",new Object[]{personid},
                                new int[]{java.sql.Types.INTEGER});
    }

    public Person getPerson(int personid) {
        return (Person)jdbcTemplate.queryForObject("select * from person where id=?", new Object[]{personid}, new int[]{java.sql.Types.INTEGER}, new PersonRowMapper());
    }//获取指定记录，参数3：需要回调方法

    public List<Person> getPersons() {
        return (List<Person>)jdbcTemplate.query("select * from person", new PersonRowMapper());
    }

}

回调的类

package daniel.jdbctest.service.impl;
import daniel.jdbctest.bean.Person;
import java.sql.ResultSet;
import java.sql.SQLException;
import org.springframework.jdbc.core.RowMapper;

public class PersonRowMapper implements RowMapper{

    public Object mapRow(ResultSet rs, int index) throws SQLException {
       Person person = new Person(rs.getString("name"),rs.getString("password"));
       person.setId(rs.getInt("id"));
       return person;
    }

}

测试类

import daniel.jdbctest.bean.Person;
import daniel.jdbctest.service.PersonService;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.junit.Test;
import org.junit.BeforeClass;
public class TestJdbc{
    private static PersonService personservice ;
   @BeforeClass
    public static void main() throws Exception{
    try{
      ApplicationContext  cxt = new ClassPathXmlApplicationContext("beanconfig.xml");
      personservice = (PersonService) cxt.getBean("personService");
    }
    catch(Exception e)
    {
        e.printStackTrace();        
    }
   
    }
 // @Test 
   public  void save ()throws Exception
    {
       try{
        Person p = new Person("daniel","123456");
        personservice.save(p);
      }
       catch(Exception e)
       {
           e.printStackTrace();
       }
    }
  // @Test
   public void delete()throws Exception
   {
       personservice.delete(1239);
   }
   @Test
   public void update()throws Exception
   {
        Person p = personservice.getPerson(1);
        if(p.getName().equals("tiger"))
        {
             p.setPassword("11111");
             p.setName("jason");
        }       
       personservice.update(p);
   }
   @Test
   public void getPersons()throws Exception
   {
       for(Person person:personservice.getPersons()){
           System.out.println("name:"+person.getName()+" password:"+person.getPassword());
       }
           
   }
}
