问题 I am currently writing an application which should use a replica set of MongoDB. It is a Spring Boot based application and the following properties work perfectly fine to connect to one server: spring.data.mongodb.host=localhost spring.data.mongodb.port=27017 spring.data.mongodb.database=demo This is absolutely fine for my local dev environment. But later on it should run against a MongoDB replica set, so I have to provide at least 2, better 3 replica set seeds, but how can I do this with

问题 I'm using spring-data-rest and I have a MongoRepository like this: @RepositoryRestResource interface MyEntityRepository extends MongoRepository<MyEntity, String> { } I would like to allow the GET methods but disable PUT, POST, PATCH and DELETE (read only web service).

问题 I'm trying to implement in Spring Data using MongoTemplate the following working mongoDb query: db.answers.aggregate([ { "$match" : { "object_id" : "1" } }, { "$project": { 'answer_list': 1, 'profile': { $filter : { input: '$answer_list', as: 'answer', cond: { $eq: [ '$$answer.question', 2 ] } } } } }, { "$unwind" : "$profile"}, { "$unwind" : "$answer_list"}, { "$group" : { "_id" : { "question" : "$answer_list.question", "answer" : "$answer_list.answer", "criteria" : "$profile.answer"},

问题 How could I customize the MappingMongoConverter within my Spring-Boot-Application (1.3.2.RELEASE) without changing any of the mongo-stuff which is autoconfigured by spring-data? My current solution is: @Configuration public class MongoConfig { @Autowired private MongoDbFactory mongoFactory; @Autowired private MongoMappingContext mongoMappingContext; @Bean public MappingMongoConverter mongoConverter() throws Exception { DbRefResolver dbRefResolver = new DefaultDbRefResolver(mongoFactory);

问题 Is there something like JPA Specifications for Spring Data MongoDB Repositories? If not, how can I make dynamic queries with repositories? A classic scenario could be a search form with optional fields that the user will fill. 回答1: I found myself a way. The trick can be done using QueryDSL , in the following way: First, add the QueryDSL dependencies: <dependency> <groupId>com.mysema.querydsl</groupId> <artifactId>querydsl-mongodb</artifactId> <version>${querydsl-mongo.version}</version> <

问题 I am developing Test cases for the Spring Data Mongo Services. org.mockito.exceptions.misusing.WrongTypeOfReturnValue: Optional cannot be returned by stream() stream() should return Stream *** If you're unsure why you're getting above error read on.
