1 mysql 创建数据库脚本

2 创建与数据库表 Siswa 对应的 Pojo 类
Paket com.mtour.mybatis.demo; import javax.xml.bind.annotation.xmlrooteLement; @xmlrooteLementPublic class public get public {int id; name string; int this.id public getid () {return id public void setid public (int id) {this. setName (name string) {this.name = name;} public int getage () {return usia;} public void setage (int usia) {this.age = usia;}}3 创建映射 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 namespace = "com.mtour.mybatis.demo.studentmapper"> <pilih id = "getStudent" parameTerType = "int" resultType = "com.mtour.mybatis.demo.student"> Pilih * dari siswa di mana id =#{id} </mapper> mapper> 4. 创建 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<" config.dtd"> <configation>< "configry>" config.dtd"> " id="development"><transactionManager type="JDBC" /><!-- 配置数据库连接信息 --><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"/> <name properti = "kata sandi" value = ""/> </dateSource> </urveening> </sulvirments> <mappers> <mapper resource = "com/mtour/mybatis/demo/studentmapper.xml"/> </pappers> </konfigurasi>
5. 创建 istirahat 资源
Paket com.mtour.mybatis.demo; impor java.io.ioexception; impor java.io.inputstream; impor org.apache.ibatis.session.sqlsession; impor org.apache.ibatis.Sesesies.sqlsessionfactory; impor org.apache.apache.ibatis.sesesiespyfactoryf; javax.ws.rs.get; impor javax.ws.rs.path; impor javax.ws.rs.produces; impor javax.ws.rs.pathparam; impor javax.ws.rs.core.mediatype; @Path ("/student") Demo kelas publik {statis string resource = "conf.xml"; static inputstream is = demo.class.getClassLoader (). GetResourceasStream (sumber daya); static SqlSessionFactory (iSpactory = new SqlSessionFactoryBactoryBuilder (). string publik sayhello () {return "Hello Jersey, First Demo"; } @Get @path ("/{param}") @produces ("text/polos; charset = utf-8") string publik SayHelloToutF8 (@pathparam ("param") string username) {return "hello" + username; } @Get @path ("/getStudent/{id}") @produces (mediatype.application_json) Mahasiswa publik getUserjson (@pathparam ("id") ID string) {integer studentId = integer.valueof (id); SQLSesion sesion = sessionFacory.opension. "com.mtour.mybatis.demo.studentmapper.getstudent"; student s = session.selectone (pernyataan, studentId); session.close (); return s; }}6. 启动调试
