1.UserMapper.java ~~~ //新增，返回影響行數 int save(User u); ~~~ 2.UserMapper.xml ~~~ <!--新增語句--> <insert id="save" parameterType="com.nobb.domain.User"> insert into t_user(name,password) values(#{name},#{password}) </insert> ~~~ 3.Test.java ~~~ public class Test { @org.junit.Test public void testFindAll() { //定義配置文件路徑 String resource = "mybatis-config.xml";//不能加 根目錄 / InputStream inputStream = null; try {//加載配置文件 inputStream = Resources.getResourceAsStream(resource); } catch (IOException e) { e.printStackTrace(); }//根據配置文件創建SessionFactory對象 SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream); //獲得SqlSession SqlSession session = sqlSessionFactory.openSession(); //獲得UserMapper接口的實現類 UserMapper mapper = session.getMapper(UserMapper.class); //調用UserMapper方法,執行xml中定義的SQL語句 // List<User> list = mapper.findAll(); //打印list // System.out.println(list); // User u = mapper.findById(15); // System.out.println(u); User u = new User(); u.setName("nobb1121"); u.setPassword("11211"); int row = mapper.save(u); //注：寫入需要顯示提交session session.commit(); session.close(); System.out.println(row); } } ~~~
