mongodb+springboot如何修改深层嵌套对象-创新互联
mongodb+spring boot如何修改深层嵌套对象,很多新手对此不是很清楚,为了帮助大家解决这个难题,下面小编将为大家详细讲解,有这方面需求的人可以来学习下,希望你能有所收获。
在成都做网站、网站设计过程中,需要针对客户的行业特点、产品特性、目标受众和市场情况进行定位分析,以确定网站的风格、色彩、版式、交互等方面的设计方向。成都创新互联公司还需要根据客户的需求进行功能模块的开发和设计,包括内容管理、前台展示、用户权限管理、数据统计和安全保护等功能。在最近的工作中使用到对mongodb深层嵌套对象的修改,研究了很久,故做此笔记。
1.开发环境:mongodb+spring boot项目,使用mongoTemplate进行修改
2.数据为三层嵌套TopicModel——>TopicTableModel——>TopicColumnModel
3.修改代码展示
(1)修改第二级TopicTableModel对象
@Override public boolean updateTableModel(TopicTableModel tableModel) { Query query = new Query(); query.addCriteria(Criteria.where("tableList.tableId").is(tableModel.getTableId())); Update update = new Update().set("tableList.$.tableName", tableModel.getTableName()) .set("tableList.$.tableComment", tableModel.getTableComment()) .set("tableList.$.status", Integer.valueOf(tableModel.getStatus())); // .set("tableList.$.topicCode", tableModel.getTopicCode()); UpdateResult tableUr = this.mongoTemplate.upsert(query, update, TopicModel.class); if ((tableUr.getMatchedCount() > 0L) || (tableUr.getUpsertedId() != null)) { return true; } return false; }
(3)修改第三级(TopicColumnModel),需要先遍历定位到修改的第三级对像的索引
@Override public boolean updateColumnModel(TopicColumnModel topicColumnModel, String tmId, String tbId) { Query query = new Query(); query.addCriteria(Criteria.where("tableList.tableId").is(tbId)); Update update = new Update(); ListtopicModels = mongoTemplate.find(query, TopicModel.class); for (int i = 0; i < topicModels.size(); i++) { if (topicModels.get(i).getId().equals(tmId)) { List topicTableModels = topicModels.get(i).getTableList(); for (int j = 0; j < topicTableModels.size(); j++) { if (topicTableModels.get(j).getTableId().equals(tbId)) { List topicColumnModels = topicTableModels.get(j).getColList(); for (int k = 0; k < topicColumnModels.size(); k++) { if (topicColumnModels.get(k).getColId().equals(topicColumnModel.getColId())) { update.set("tableList.$.colList." + k + ".colName",topicColumnModel.getColName()) .set("tableList.$.colList."+ k +".desc1", topicColumnModel.getDesc1()) .set("tableList.$.colList." + k +".desc2", topicColumnModel.getDesc2()) .set("tableList.$.colList." + k +".internalMark", topicColumnModel.getInternalMark()) .set("tableList.$.colList." + k +".qualifierMark", topicColumnModel.getQualifierMark()) .set("tableList.$.colList." + k +".chineseName", topicColumnModel.getChineseName()) .set("tableList.$.colList." + k +".dataSource", topicColumnModel.getDataSource()) .set("tableList.$.colList." + k +".getRules", topicColumnModel.getGetRules()) .set("tableList.$.colList." + k +".dataType", topicColumnModel.getDataType()) .set("tableList.$.colList." + k +".dataLength", topicColumnModel.getDataLength()) .set("tableList.$.colList." + k +".pkey", topicColumnModel.isPkey()) .set("tableList.$.colList." + k +".index", topicColumnModel.isIndex()) .set("tableList.$.colList." + k +".nullAble", topicColumnModel.isNullAble()) .set("tableList.$.colList." + k +".unique", topicColumnModel.isUnique()) .set("tableList.$.colList." + k +".colComment", topicColumnModel.getColComment()) .set("tableList.$.colList." + k +".defaultValue", topicColumnModel.getDefaultValue()) .set("tableList.$.colList." + k +".check", topicColumnModel.getCheck()) .set("tableList.$.colList." + k +".attributeType", topicColumnModel.getAttributeType()); } } } } } } UpdateResult tableUr = this.mongoTemplate.updateFirst(query, update, TopicModel.class); if ((tableUr.getMatchedCount() > 0L) || (tableUr.getUpsertedId() != null)) { return true; } return false; }
