spring-data-mongodb

问题 I would like to make my web application that is using mongodb and spring-data multitenat. Basically I would like to replicate all my entities(collections) into different databases. Then (based on some rule as for example the user that is logged in the system) I want to store some entity instance (document) into the right database. For example I have a Service Called DBNameProviderService.getDbName() that dynamically returns me the name of the database. How can I use this service to

问题 I'm trying to compare a value with multiples fields with Spring-Data-MongoDB 1.10.0, I'm using @Query because the nested document is an Object with dynamic fields. But if I use the same identifier like ?5 in all the conditions, I got an error: exception="com.mongodb.util.JSONParseException: { companyType: "SPONSOR", companyId: 6710890, delivered: false, createdAt: { $gt: { "$date" : "2019-09-01T03:00:00.000Z"}, $lt: { "$date" : "2019-09-26T02:59:59.999Z"} }, $or:[ {requestPayload

问题 I'm trying to simply do a comparison between my fields but it doesn't seems to work with spring data : query.addCriteria(Criteria.where("active").gt("limit")); Active and limit are 2 fields of my collection, and I wand to display all fields that exceed the limit. This limit is different for each item so I cannot do gt(200) for example... There is anyway to do that ? 回答1: You can fall back to your java driver and issue a $where query: DBObject obj = new BasicDBObject(); obj.put( "$where",

问题 How do I expose a new method in a MongoRepository extension class to the generated REST API and include the same ALPS/HATEOAS metadata, links etc. I have the usual Spring Data MongoDB repository: public interface CollectionRepository extends Repository<Collection, String> { // Simple queries Collection findFirstByName(@Param("name") String name); } Now I want to add another method and have it integrate into the generated Repository REST API so that it is included in the {repository}

问题 I have created an index with unique=true on one of the fields in my Mongo document. This works as expected - it disallows duplicates by overwriting the existing entry. I would like to disallow overwrites, and instead get an error or exception when an attempt is made to insert a duplicate. Is there any way to do this?
