如何用mongodb和springboot修改深層嵌套對象
如何用MongoDB和spring boot修改深層嵌套對象？這篇文章運用了實例代碼展示，代碼非常詳細，可供感興趣的小伙伴們參考借鑒，希望對大家有所幫助。

1.開發(fā)環(huán)境：mongodb+spring boot項目，使用mongoTemplate進行修改
2.數(shù)據(jù)為三層嵌套TopicModel——>TopicTableModel——>TopicColumnModel
3.修改代碼展示
（1）修改第二級TopicTableModel對象
@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）修改第三級（TopicColumnModel），需要先遍歷定位到修改的第三級對像的索引
@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;
