1、批量添加元素session.insert(String string，Object o)

public void batchInsertStudent(){
    List ls = new ArrayList();
    for(int i = 5;i < 8;i++){
        Student student = new Student();
        student.setId(i);
        student.setName("maoyuanjun" + i);
        student.setSex("man" + i);
        student.setTel("tel" + i);
        student.setAddress("浙江省" + i);
        ls.add(student);
    }
    SqlSession session = SessionFactoryUtil.getSqlSessionFactory().openSession();
    session.insert("mybatisdemo.domain.Student.batchInsertStudent", ls);
    session.commit();
    session.close();
}


    INSERT INTO STUDENT (id,name,sex,tel,address)
    VALUES 
    
        (#{item.id},#{item.name},#{item.sex},#{item.tel},#{item.address})
    

 

2、批量修改session. insert (String string,Object o)

实例1：
public void batchUpdateStudent(){
    List ls = new ArrayList();
    for(int i = 2;i < 8;i++){
        ls.add(i);
    }
    SqlSession session = SessionFactoryUtil.getSqlSessionFactory().openSession();
    session.insert("mybatisdemo.domain.Student.batchUpdateStudent",ls);
    session.commit();
    session.close();
}

    UPDATE STUDENT SET name = "5566" WHERE id IN
    
        #{item}
    


实例2：
public void batchUpdateStudentWithMap(){
    List ls = new ArrayList();
    for(int i = 2;i < 8;i++){
        ls.add(i);
    }
    Map map = new HashMap();
    map.put("idList", ls);
    map.put("name", "mmao789");
    SqlSession session = SessionFactoryUtil.getSqlSessionFactory().openSession();
    session.insert("mybatisdemo.domain.Student.batchUpdateStudentWithMap",map);
    session.commit();
    session.close();
}

    UPDATE STUDENT SET name = #{name} WHERE id IN 
     
        #{item} 
    

3、批量删除session.delete(String string,Object o)

public void batchDeleteStudent(){
    List ls = new ArrayList();
    for(int i = 4;i < 8;i++){
        ls.add(i);
    }
    SqlSession session = SessionFactoryUtil.getSqlSessionFactory().openSession();
    session.delete("mybatisdemo.domain.Student.batchDeleteStudent",ls);
    session.commit();
    session.close();
}

    DELETE FROM STUDENT WHERE id IN
     
        #{item}
