1 mysql 创建数据库脚本

-- phpMyAdmin SQL Dump -- version 4.2.11 -- http://www.phpmyadmin.net -- -- Host: localhost -- Generation Time: 2016-08-02 18:13:50 -- 服务器版本： 5.6.21 -- PHP Version: 5.6.3 SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO"; SET time_zone = "+00:00"; /*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */; /*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */; /*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */; /*!40101 SET NAMES utf8 */; -- -- Database: `mybatis` -- -- -------------------------------------------------------- -- -- 表的结构 `Student` -- CREATE TABLE IF NOT EXISTS `Student` ( `id` int(10) NOT NULL, `name` varchar(256) NOT NULL, `age` int(4) NOT NULL ) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=latin1; -- -- 转存表中的数据 `Student` -- INSERT INTO `Student` (`id`, `name`, `age`) VALUES (1, 'zhansan', 20); -- -- Indexes for dumped tables -- -- -- Indexes for table `Student` -- ALTER TABLE `Student` ADD PRIMARY KEY (`id`); -- -- AUTO_INCREMENT for dumped tables -- -- -- AUTO_INCREMENT for table `Student` -- ALTER TABLE `Student` MODIFY `id` int(10) NOT NULL AUTO_INCREMENT,AUTO_INCREMENT=2; /*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */; /*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */; /*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */;

2 创建与数据库表Student对应的pojo类

package com.mtour.mybatis.demo; import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class Student { int id; String name; int age; 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; } }

3 创建映射 studentMapper

<"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.mtour.mybatis.demo.studentMapper"> <select id="getStudent" parameterType="int" resultType="com.mtour.mybatis.demo.Student"> select * from Student where id=#{id} </select> </mapper>

4. 创建 conf.xml

<"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" /> <> <dataSource type="POOLED"> <property name="driver" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/mybatis" /> <property name="username" value="root" /> <property name="password" value="" /> </dataSource> </environment> </environments> <mappers> <mapper resource="com/mtour/mybatis/demo/studentMapper.xml"/> </mappers> </configuration>

5. 创建 rest 资源

package com.mtour.mybatis.demo; import java.io.IOException; import java.io.InputStream; import org.apache.ibatis.session.SqlSession; import org.apache.ibatis.session.SqlSessionFactory; import org.apache.ibatis.session.SqlSessionFactoryBuilder; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.Produces; import javax.ws.rs.PathParam; import javax.ws.rs.core.MediaType; @Path("/student") public class demo { static String resource = "conf.xml"; static InputStream is = demo.class.getClassLoader().getResourceAsStream(resource); static SqlSessionFactory sessionFactory = new SqlSessionFactoryBuilder().build(is); @GET @Produces(MediaType.TEXT_PLAIN) public String sayHello() { return "hello jersey , first demo" ; } @GET @Path("/{param}") @Produces("text/plain;charset=UTF-8") public String sayHelloToUTF8(@PathParam("param") String username) { return "Hello " + username; } @GET @Path("/getstudent/{id}") @Produces(MediaType.APPLICATION_JSON) public Student getUserJson(@PathParam("id") String id) { Integer studentId = Integer.valueOf(id); SqlSession session = sessionFactory.openSession(); String statement = "com.mtour.mybatis.demo.studentMapper.getStudent"; Student s = session.selectOne(statement, studentId); session.close(); return s; } }
