mybatis 和 mybatis-spring

一、

1. 实体bean 　　　　

package com.mybatisBean;

public class User {

    private Integer id;

    private String name;

    private String age;

    public Integer getId() {

        return id;

    }

    public void setId(Integer id) {

        this.id = id;

    }

    public String getName() {

        return name;

    }

    public void setName(String name) {

        this.name = name;

    }

    public String getAge() {

        return age;

    }

    public void setAge(String age) {

        this.age = age;

    }

}

2.dao类

package com.mybatisDao;

import java.util.List;

import com.mybatisBean.User;

public interface UserDao {

    public List<User> selectAll();

}

3.dao 映射文件

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.mybatisDao.UserDao">

    <select id="selectAll" resultType="com.mybatisBean.User">

        select * from user

    </select>

</mapper>

　4.配置文件

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>

    <!-- <environments default="development">

        <environment id="development">

            <transactionManager type="JDBC"></transactionManager>

            <dataSource type="POOLED">

                <property name="driver" value="com.mysql.jdbc.Driver"/>

                <property name="url" value="jdbc:mysql://localhost:3306/test_mysql?useUnicode=true&amp;characterEncoding=UTF-8&amp;zeroDateTimeBehavior=convertToNull"/>

                <property name="username" value="root"/>

                <property name="password" value="123456"/>

            </dataSource>

        </environment>

    </environments> -->

    <mappers>

        <mapper resource="mybatisMapper/UserMapper.xml"/>

    </mappers>

</configuration>

5. 测试

package com.mybatisTest;

import java.io.Reader;

import java.util.List;

import org.apache.ibatis.io.Resources;

import org.apache.ibatis.session.SqlSession;

import org.apache.ibatis.session.SqlSessionFactory;

import org.apache.ibatis.session.SqlSessionFactoryBuilder;

import com.mybatisBean.User;

import com.mybatisDao.UserDao;

/*

 * mybatis 第一种方式

 * 1. 创建实体，2. 创建dao ,声明接口   3. 创建dao 对应的映射文件

 * 4. 创建mybatis 配置文件，声明数据库连接，配置映射文件 5.通过mybatis配置文件和sessionfactoryBuilder引用

 * 第一种方式在 mybatis 配置文件中配置数据库链接

 */

public class TestUser {

    public static void main(String[] args) throws Exception{

        String resource="mybatis-configuration.xml";

        Reader reader=Resources.getResourceAsReader(resource);

        SqlSessionFactoryBuilder bulider=new SqlSessionFactoryBuilder();

        SqlSessionFactory factory=bulider.build(reader);

        SqlSession session=factory.openSession();

        UserDao userdao=session.getMapper(UserDao.class);

        List<User> list=userdao.selectAll();

        for(User user:list){

            System.out.println(user.getName()+":"+user.getAge());

        }

        session.commit();

        session.close();

    }

}

jar 包，主要有 mybatis-3.1.1.jar 和 mysql-connector-java-5.1.jar

二、

　　多出的部分。

　　1. service 接口和实现

package com.mybatisService.User;

import java.util.List;

import com.mybatisBean.User;

public interface UserService {

	public List<User> selectAll();

}

package com.mybatisService.User;

import java.util.List;

import com.mybatisBean.User;

import com.mybatisDao.UserDao;

public class UserImpl implements UserService{

	private UserDao userdao;

	public UserDao getUserdao() {

		return userdao;

	}

	public void setUserdao(UserDao userdao) {

		this.userdao = userdao;

	}

	@Override

	public List<User> selectAll() {

		return this.userdao.selectAll();

	}

}

　　2. spring 配置文件

<?xml version="1.0" encoding="UTF-8"?>

<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.apache.commons.dbcp.BasicDataSource" destroy-method="close">

        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>

        <property name="url" value="jdbc:mysql://localhost:3306/test_mysql?useUnicode=true&amp;characterEncoding=UTF-8&amp;zeroDateTimeBehavior=convertToNull"/>

        <property name="username" value="root"/>

        <property name="password" value="123456"/>

</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

    <property name="configLocation" value="classpath:mybatis-configuration.xml"></property>

    <property name="dataSource" ref="dataSource"></property>

</bean>

<bean id="userDao" class="org.mybatis.spring.mapper.MapperFactoryBean">

    <property name="mapperInterface" value="com.mybatisDao.UserDao"></property>

    <property name="sqlSessionFactory" ref="sqlSessionFactory"></property>

</bean>

<bean id="userservice" class="com.mybatisService.User.UserImpl">

    <property name="userdao" ref="userDao"></property>

</bean>

</beans>

mybatis 配置文件中的数据库链接不需要了。

基于以上添加 mybatis

添加jar 包 mybats-3.1.jar mysql-connector-java-5.1 mybatis-spring.jar ,commons-dbcp,commons-pool,spring-jdbc 等

UserDao.java

package com.mybatisdao;

import java.util.List;

import com.bean.User;

public interface UserDao {

    public List<User> selectAll();

}

UserDaoMapper.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.mybatisdao.UserDao">

    <select id="selectAll" resultType="com.bean.User">

        select * from user

    </select>

</mapper>

mybatis-configuration.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>

    <!-- <environments default="development">

        <environment id="development">

            <transactionManager type="JDBC"></transactionManager>

            <dataSource type="POOLED">

                <property name="driver" value="com.mysql.jdbc.Driver"/>

                <property name="url" value="jdbc:mysql://localhost:3306/test_mysql?useUnicode=true&amp;characterEncoding=UTF-8&amp;zeroDateTimeBehavior=convertToNull"/>

                <property name="username" value="root"/>

                <property name="password" value="***"/>

            </dataSource>

        </environment>

    </environments> -->  <!--结合spring 时要在Spring  配置文件中配置 数据库链接-->

    <mappers>

        <mapper resource="com/mybatisMapper/UserDaoMapper.xml"/>

    </mappers>

</configuration>

更改HappyNewYearIml.java

package com.service;

import java.util.List;

import javax.jws.WebService;

import com.bean.Person;

import com.bean.User;

import com.mybatisdao.UserDao;

@WebService(endpointInterface = "com.service.HappyNewYear")

public class HappyNewYearImpl implements HappyNewYear

{

    private UserDao userdao;  //主要改动的地方

    public UserDao getUserdao() {

        return userdao;

    }

    public void setUserdao(UserDao userdao) {

        this.userdao = userdao;

    }

    public String sayHello(Person person)

    {

        List<User> list=userdao.selectAll();

        String  ss="";

        for(User u:list){

            if(u.getId()+""==person.getFirstName()){

                ss=u.getName()+"年龄"+u.getAge();

            }

        }

        return ss==""?"没有":ss;

    }

}

applicationContext.xml更改

<beans xmlns="http://www.springframework.org/schema/beans"
