1、批量添加元素session.insert(String string，Object o)
- public void batchInsertStudent(){
- List<Student> ls = new ArrayList<Student>();
- 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 id="batchInsertStudent" parameterType="java.util.List">
- INSERT INTO STUDENT (id,name,sex,tel,address)
- VALUES
- <foreach collection="list" item="item" index="index" separator="," >
- (#{item.id},#{item.name},#{item.sex},#{item.tel},#{item.address})
- </foreach>
- </insert>
2、批量修改session. insert (String string,Object o)
- 實例1：
- public void batchUpdateStudent(){
- List<Integer> ls = new ArrayList<Integer>();
- 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 id="batchUpdateStudent" parameterType="java.util.List">
- UPDATE STUDENT SET name = "5566" WHERE id IN
- <foreach collection="list" item="item" index="index" open="(" separator="," close=")" >
- #{item}
- </foreach>
- </update>
-
- 實例2：
- public void batchUpdateStudentWithMap(){
- List<Integer> ls = new ArrayList<Integer>();
- for(int i = 2;i < 8;i++){
- ls.add(i);
- }
- Map<String,Object> map = new HashMap<String,Object>();
- 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 id="batchUpdateStudentWithMap" parameterType="java.util.Map" >
- UPDATE STUDENT SET name = #{name} WHERE id IN
- <foreach collection="idList" index="index" item="item" open="(" separator="," close=")">
- #{item}
- </foreach>
- </update>
3、批量刪除session.delete(String string,Object o)
- public void batchDeleteStudent(){
- List<Integer> ls = new ArrayList<Integer>();
- 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 id="batchDeleteStudent" parameterType="java.util.List">
- DELETE FROM STUDENT WHERE id IN
- <foreach collection="list" index="index" item="item" open="(" separator="," close=")">
- #{item}
- </foreach>
- </delete>
