spring-data-mongodb

I'm going through Spring Data MongoDB - Reference Documentation and I'm finding the examples to be a bit too simplistic. In particular I'm trying to understand how to handle stale data in concurrent environments. For instance, imagine I have the following entity: public class Person { private final String username; private final String firstname; private final String lastname; [...] } Now if I use CrudRepository to save/update/remove my entities, then imagine a scenario in which two threads retrieve the same entity, one of them removes it, and the other one updates its lastname field. If the

I'm building a MongoDb rest application with spring boot 1.1.5. I have created a repository: @RepositoryRestResource(collectionResourceRel = "SourceProductV1Repository", path = "SourceProductV1Repository") public interface SourceProductV1Repository extends MongoRepository<SourceProductV1Model, String> { public List<SourceProductV1Model> findByUser (@Param("user") MongoUser user); } I Defined a converter to convert String to MongoUser (the converter is correctly registered in the spring context): @Component public class String2MongoUserConverter implements Converter<String, MongoUser>{ private

I just started developing some app in Java with spring-data-mongodb and came across some issue that I haven't been able to solve: Have a couple of document beans like this: @Document(collection="myBeanBar") public class BarImpl implements Bar { String id; Foo foo; // More fields and methods ... } @Docuemnt public class FooImpl implements Foo { String id; String someField; // some more fields and methods ... } And I have a repository class with a method that simply invokes a find similar to this: public List<? extends Bar> findByFooField(final String fieldValue) { Query query = Query.query

一、前言 其实，以前项目组也使用过mongodb，只是那时候是作为主数据库来使用，所以在框架方面会更加复杂，比如使用jpa，如果只是把mongodb作为附数据库使用的话，个人认为通过spring-data-mongodb的mongoTemple来操作数据库即可。 二、spring 整合mongodb 配置文件如下：（用户名 密码缺失） <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mongo="http://www.springframework.org/schema/data/mongo" xsi:schemaLocation="http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www
