原因：经过查看文档和源代码才发现，Criteria的where方法是一个静态工厂方法，它会返回一个实例化的criteria对象，所以就不需要自己new 一个cr...

目录一. 背景二. 使用
一. 背景MongoTemplate提供了很多内置命令用于增删改查
比如：executeQuery/find/findAndModify等
同时还提供了执行动态命令的语句executeCommand(对应MongoDB命令：runCommand)二. 使用MongoDB原生命令：runCommanddb.runCommand({"find":"tablename","filter":{"fieldName":{$exists:true}},"limit" : 10})对应的MongoTemplate方法executeCommandString jsonCommand = "{\n" +"\"find\":\"" + tablename + ...
1. 简介
MongDB的MongoTemplate对Query的定义是Query object representing criteria, projection, sorting and query hints，即MongoDB使用Query对象完成条件、投影、排序等查询操作。
2. 使用方法
public List<GeoModel> query() {Query query = new Query();Criteria criteria = Criteria.where("uId").is("4").and("time").gt(LocalDateTime.now()).lt(LocalDateTime.now().plusHours(10));query.addCriteria(criteria);return ...

如果使用MongoRepository,您可以拥有以下代码：@Repository
public interface UserRepo extends MongoRepository<User, String> {// additional methods go here } 然后你做userRepo.save()find()等来做CRUD操作.
或者你只是MongoTemplate并做CRUD操作.
我的问题是哪个更受欢迎？每种方法的优缺点是什么？谢谢！解决方法:好的,通过查看源代码MongoRepository消耗mongoTemplate并提供一组常用的DAO API,换句话说,使用MongoRepositor...
