插件的使用如下:
@Override
public List<SessionChatRecordEntity> getSessionRecordByPageNo(Integer sessionId, Integer pageNo, Integer size) {
// 创建一个分页对象
IPage<SessionChatRecordEntity> page = new Page<>(pageNo, size);
// 查询条件:根据sessionId查询,并按createTime降序排列
IPage<SessionChatRecordEntity> resultPage = baseMapper.selectPage(page, new QueryWrapper<SessionChatRecordEntity>()
.eq("session_id", sessionId)
.orderByAsc("session_chat_id"));
// 返回分页结果中的数据列表
return resultPage.getRecords();
}
