廢話不多說了，直接步入正題了。

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)

實例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}

實例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、批量刪除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}

好了，本文到此結(jié)束，希望對大家有所幫助。
