1 mysql 創立數據庫劇本
-- phpMyAdmin SQL Dump -- version 4.2.11 -- http://www.phpmyadmin.net -- -- Host: localhost -- Generation Time: 2016-08-02 18:13:50 -- 辦事器版本： 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` -- -- -------------------------------------------------------- -- -- 表的構造 `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; -- -- 轉存表中的數據 `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 創立與數據庫表Student對應的pojo類
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 創立映照 studentMapper
<?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.mtour.mybatis.demo.studentMapper">
<select id="getStudent" parameterType="int"
resultType="com.mtour.mybatis.demo.Student">
select * from Student where id=#{id}
</select>
</mapper>
4. 創立 conf.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" /> <!-- 設置裝備擺設數據庫銜接信息 --> <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. 創立 rest 資本
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;
}
}
