myBatis批量平添，修改和删除

myBatis批量添加，修改和删除
1、批量添加元素session.insert(String string，Object o)

[plain] view plaincopypublic 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)

[plain] view plaincopy实例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>    实例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、批量删除session.delete(String string,Object o)

[plain] view plaincopypublic 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>
