dao类中多个参数需要在前面加注解@Param

执行insert之后需要session.commit()

import java.io.InputStream;

import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;

public class AA {
    String resource;
    InputStream inputStream;
    SqlSessionFactory sqlSessionFactory;

    public AA() throws Exception {
        resource = "mybatis-config.xml";
        inputStream = Resources.getResourceAsStream(resource);
        sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
    }

    public static void main(String[] args) throws Throwable {
        AA test1 = new AA();
        SqlSession session = test1.sqlSessionFactory.openSession();
        try {
            RegUtil regUtil = session.getMapper(RegUtil.class);
            System.out.println(
                    regUtil.insertUser("1815277", "joy"));
            session.commit();
        } finally {
            session.close();
        }
    }
}

import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Update;

public interface RegUtil {

    @Insert("insert into t_test(id,name) values(${id},${name})" )
    public boolean inserUser(@Param("id")Stringid,@Param("name")String name);
    
    
}
