mongodb+spring boot修改深层嵌套对象，修改第二，三级对象

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();
        List topicModels = 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;
    }
