myBatis批量添加,修改和删除

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}
