MongoRepository学习-regex

本文主要是介绍MongoRepository学习-regex，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

在MongoRepository中使用Regex,

Keyword	Sample	Logical result
GreaterThan	findByAgeGreaterThan(int age)	{"age" : {"$gt" : age}}
LessThan	findByAgeLessThan(int age)	{"age" : {"$lt" : age}}
Between	findByAgeBetween(int from, int to)	{"age" : {"$gt" : from, "$lt" : to}}
IsNotNull, NotNull	findByFirstnameNotNull()	{"age" : {"$ne" : null}}
IsNull, Null	findByFirstnameNull()	{"age" : null}
Like	findByFirstnameLike(String name)	{"age" : age} ( age as regex)
Regex	findByFirstnameRegex(String firstname)	{"firstname" : {"$regex" : firstname }}
(No keyword)	findByFirstname(String name)	{"age" : name}
Not	findByFirstnameNot(String name)	{"age" : {"$ne" : name}}
Near	findByLocationNear(Point point)	{"location" : {"$near" : [x,y]}}
Within	findByLocationWithin(Circle circle)	{"location" : {"$within" : {"$center" : [ [x, y], distance]}}}
Within	findByLocationWithin(Box box)	{"location" : {"$within" : {"$box" : [ [x1, y1], x2, y2]}}}True
IsTrue, True	findByActiveIsTrue()	{"active" : true}
IsFalse, False	findByActiveIsFalse()	{"active" : false}
Exists	findByLocationExists(boolean exists)	{"location" : {"$exists" : exists }}
