就我而言，也有相同的情况。我使用了循环检查该记录是否存在于databse中，然后据此将该对象添加到两个arraylist中以进行插入或更新。然后使用批处理进行插入并在for循环后进行更新以列出该列表。
这是前 根据不同的条件进行更新
1]这是要更新
<foreach collection="attendingUsrList" item="model" separator=";"> UPDATE parties SET attending_user_count = #{model.attending_count} WHERe fb_party_id = #{model.eid} </foreach>2]这是用于插入
<insert id="insertAccountabilityUsers" parameterType="AccountabilityUsersModel" useGeneratedKeys="false"> INSERT INTO accountability_users ( accountability_user_id, accountability_id, to_username, record_status, created_by, created_at, updated_by, updated_at ) VALUES <foreach collection="usersList" item="model" separator=","> ( #{model.accountabilityUserId}, #{model.accountabilityId}, #{model.toUsername}, 'A', #{model.createdBy}, #{model.createdAt}, #{model.updatedBy}, #{model.updatedAt} ) </foreach></insert>在dao方法中声明为
void insertAccountabilityUsers(@Param("usersList") List<AccountabilityUsersModel> usersList);更新资料
这是我的批处理会话代码
public static synchronized SqlSession getSqlBatchSession() { ConnectionBuilderAction connection = new ConnectionBuilderAction(); sf = connection.getConnection(); SqlSession session = sf.openSession(ExecutorType.BATCH); return session;}SqlSession session = ConnectionBuilderAction.getSqlSession();其实我已经在这个问题上给出了完整的例子
