This commit updates URLs to prefer the https protocol. Redirects are not followed to avoid accidentally expanding intentionally shortened URLs (i.e. if using a URL shortener). # Fixed URLs ## Fixed But Review Recommended These URLs were fixed, but the https status was not OK. However, the https status was the same as the http request or http redirected to an https URL, so they were migrated. Your review is recommended. * http://ethlo.com/maven (301) with 2 occurrences migrated to: https://ethlo.com/maven ([https](https://ethlo.com/maven) result 404). ## Fixed Success These URLs were switched to an https URL with a 2xx status. While the status was successful, your review is still recommended. * http://maven.apache.org/xsd/maven-4.0.0.xsd with 53 occurrences migrated to: https://maven.apache.org/xsd/maven-4.0.0.xsd ([https](https://maven.apache.org/xsd/maven-4.0.0.xsd) result 200). * http://maven.apache.org/maven-v4_0_0.xsd with 4 occurrences migrated to: https://maven.apache.org/maven-v4_0_0.xsd ([https](https://maven.apache.org/maven-v4_0_0.xsd) result 301). * http://projects.spring.io/spring-data-cassandra with 1 occurrences migrated to: https://projects.spring.io/spring-data-cassandra ([https](https://projects.spring.io/spring-data-cassandra) result 301). * http://projects.spring.io/spring-data-jpa with 1 occurrences migrated to: https://projects.spring.io/spring-data-jpa ([https](https://projects.spring.io/spring-data-jpa) result 301). * http://projects.spring.io/spring-data-ldap with 1 occurrences migrated to: https://projects.spring.io/spring-data-ldap ([https](https://projects.spring.io/spring-data-ldap) result 301). * http://projects.spring.io/spring-data-mongodb with 1 occurrences migrated to: https://projects.spring.io/spring-data-mongodb ([https](https://projects.spring.io/spring-data-mongodb) result 301). * http://projects.spring.io/spring-data-solr with 1 occurrences migrated to: https://projects.spring.io/spring-data-solr ([https](https://projects.spring.io/spring-data-solr) result 301). # Ignored These URLs were intentionally ignored. * http://maven.apache.org/POM/4.0.0 with 114 occurrences * http://www.w3.org/2001/XMLSchema-instance with 57 occurrences Original pull request: #454
Spring Data MongoDB - Query-by-Example (QBE) example
This project contains samples of Query-by-Example of Spring Data MongoDB.
Support for Query-by-Example
Query by Example (QBE) is a user-friendly querying technique with a simple interface. It allows dynamic query creation and does not require to write queries containing field names. In fact, Query by Example does not require to write queries using JPA-QL at all.
An Example takes a data object (usually the entity object or a subtype of it) and a specification how to match properties. You can use Query by Example with MongoOperations and Repositories.
public interface PersonRepository extends CrudRepository<Person, String>, QueryByExampleExecutor {
}
Example<Person> example = Example.of(new Person("Jon", "Snow"));
repo.findAll(example);
ExampleMatcher matcher = ExampleMatcher.matching().
.withMatcher("firstname", endsWith())
.withMatcher("lastname", startsWith().ignoreCase());
Example<Person> example = Example.of(new Person("Jon", "Snow"), matcher);
repo.count(example);
This example contains two test classes to illustrate Query-by-Example with MongoOperations in MongoOperationsIntegrationTests and the usage with a Repository in UserRepositoryIntegrationTests.
