详解spring开发_JDBC操作MySQL数据库

本文介绍spring开发_JDBC操作MySQL数据库，具体如下：

项目结构：

数据库表：

/spring_1100_spring+jdbc/src/com/b510/bean/Person.java

package com.b510.bean;


public class Person {

  
  private int id;
  
  private String name;
  
  private int age;
  
  private String sex;


  public Person(int id, String name, int age, String sex) {
    this.id = id;
    this.name = name;
    this.age = age;
    this.sex = sex;
  }

  public Person() {
  }

  public int getId() {
    return id;
  }

  public void setId(int id) {
    this.id = id;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public int getAge() {
    return age;
  }

  public void setAge(int age) {
    this.age = age;
  }

  public String getSex() {
    return sex;
  }

  public void setSex(String sex) {
    this.sex = sex;
  }

}

/spring_1100_spring+jdbc/src/com/b510/service/PersonService.java

package com.b510.service;

import java.util.List;

import com.b510.bean.Person;

public interface PersonService {

  
  public abstract void save(Person person);

  
  public abstract void update(Person person);

  
  public abstract Person getPerson(Integer id);

  
  public abstract List getPerson();

  
  public abstract void delete(Integer id);

}

/spring_1100_spring+jdbc/src/com/b510/service/impl/PersonServiceBean.java

package com.b510.service.impl;

import java.util.List;

import javax.sql.DataSource;

import org.springframework.jdbc.core.JdbcTemplate;

import com.b510.bean.Person;
import com.b510.service.PersonService;


public class PersonServiceBean implements PersonService {

  
  private DataSource dataSource;
  
  private JdbcTemplate jdbcTemplate;

  // 设置数据源
  public void setDataSource(DataSource dataSource) {
    this.jdbcTemplate = new JdbcTemplate(dataSource);
  }

  public void save(Person person) {
    jdbcTemplate.update("insert into person(name,age,sex)values(?,?,?)",
 new Object[] { person.getName(), person.getAge(),
     person.getSex() }, new int[] { java.sql.Types.VARCHAR,
     java.sql.Types.INTEGER, java.sql.Types.VARCHAR });
  }

  public void update(Person person) {
    jdbcTemplate.update("update person set name=?,age=?,sex=? where id=?",
 new Object[] { person.getName(), person.getAge(),
     person.getSex(), person.getId() }, new int[] {
     java.sql.Types.VARCHAR, java.sql.Types.INTEGER,
     java.sql.Types.VARCHAR, java.sql.Types.INTEGER });

  }

  public Person getPerson(Integer id) {
    Person person = (Person) jdbcTemplate.queryForObject(
 "select * from person where id=?", new Object[] { id },
 new int[] { java.sql.Types.INTEGER }, new PersonRowMapper());
    return person;

  }

  @SuppressWarnings("unchecked")
  public List getPerson() {
    List list = jdbcTemplate.query("select * from person", new PersonRowMapper());
    return list;

  }

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

  }
}

/spring_1100_spring+jdbc/src/com/b510/service/impl/PersonRowMapper.java

package com.b510.service.impl;

import java.sql.ResultSet;
import java.sql.SQLException;

import org.springframework.jdbc.core.RowMapper;

import com.b510.bean.Person;

public class PersonRowMapper implements RowMapper {

  @Override
  public Object mapRow(ResultSet set, int index) throws SQLException {
    Person person = new Person(set.getInt("id"), set.getString("name"), set
 .getInt("age"), set.getString("sex"));
    return person;
  }

}

/spring_1100_spring+jdbc/src/com/b510/test/SpringJDBCTest.java

package com.b510.test;

import java.util.List;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.b510.bean.Person;
import com.b510.service.PersonService;

public class SpringJDBCTest {

  public static void main(String[] args) {
    ApplicationContext act = new ClassPathXmlApplicationContext("bean.xml");

    PersonService personService = (PersonService) act
 .getBean("personService");

    Person person = new Person();
    person.setName("苏东坡");
    person.setAge(21);
    person.setSex("男");

    // 保存一条记录
    personService.save(person);

    List person1 = personService.getPerson();
    System.out.println("++++++++得到所有Person");
    for (Person person2 : person1) {
      System.out.println(person2.getId() + " " + person2.getName()
   + "  " + person2.getAge() + " " + person2.getSex());
    }
    Person updatePerson = new Person();
    updatePerson.setName("Divide");
    updatePerson.setAge(20);
    updatePerson.setSex("男");
    updatePerson.setId(5);
    // 更新一条记录
    personService.update(updatePerson);
    System.out.println("******************");

    // 获取一条记录
    Person onePerson = personService.getPerson(2);
    System.out.println(onePerson.getId() + " " + onePerson.getName()
 + " " + onePerson.getAge() + " " + onePerson.getSex());
    // 删除一条记录
    personService.delete(1);
  }
}

/spring_1100_spring+jdbc/src/bean.xml

运行结果；

当然我们可以用配置文件来存放我们的数据源信息：

/spring_1100_spring+jdbc/src/jdbc.properties

driverClassName=org.gjt.mm.mysql.Driver
url=jdbc:mysql://localhost:3307/spring?useUnicode=true&characterEncoding=UTF-8
username=root
password=root
initialSize=1
maxActive=300
maxIdle=2
minIdle=1

相应要修改：

/spring_1100_spring+jdbc/src/bean.xml

运行结果是相同的：

2012-3-10 0:23:59 org.springframework.context.support.AbstractApplicationContext prepareRefresh
