废话不多说了、直接步入正题了。
1 、批量添加元素 session.insert（string string、object o）
public void batchinsertStudent（）{list <sudtent> ls = new arraylist <sustent>（）; for（int i = 5; i <8; i ++）{desute student = new Student（）; sudine.setid（i）; setsname（ "maoyuanjun" + i）; sudints.setsex（ "man" i）; sudint.setAddress（ "浙江省" + i）; ls.add（sudent）;} sqlsession session = sessionfactutil.getsqlsessionfactory（） id = "batchinsertStudent" parametertype = "java.util.list"> inserting into student（id、name、sex、tel、address）value < >（＃{item.id}、＃{item.name}、＃{item.sex}、＃{item.tel}、＃{item.address}）</foreach> </insert>2 、批量修改セッション。挿入（文字列文字列、オブジェクトo）
实例1：
public void batchupdateStudent（）{list <integer> ls = new arraylist <integer>（）; sessionfactutil.getsqlsessionfactory（）; session.insert（ "mybatisdemo.domain.student.student.student.student.batchupdateStudent"、ls）; session.commit（）; session.close（）;} <update id = "batchupdateStudent" parametertype = "java.util.util.util.util.utipe"ここで<foreach collection = "list" item = "item" index = "index" open = "（" separator = "、" close = "）">＃{iteach} </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>（ "mmao789"）; sqlsession session = sessionfactutil.getsqlsessionfactory（）。opensession（）; session.insert（ "mybatisdemo.domain.student.batchupdatudentwithmap"、map）; session.commit（）; session.commiT（）; parametertype = "java.util.map">更新学生セットname =＃{name} where id in <foreach collection = "idlist" index = "oot" item = "item" open = "（" deparator = "、" close = "）"> {item 3 、批量删除SESSION.DELETE（String String、ObjectO）
public void batchdeletestudent（）{list <integer> ls = new arraylist <integer>（）; sessionfactutil.getsqlsessionfactory（）。opensession（）; session.delete（ "mybatisdemo.domain.student.Student.batchdeleteStudent"、ls）; session.commit（）; session.close（）;} <delete id = "batchdeleteStudent" delteTudent "java in <foreach collection = "list" index = "index" item = "item" open = "（" separator = "）、" close = "）">＃{item} </foreach> </delete>好了、本文到此结束、希望对大家有所帮助。
