问题 I have an ES collection with following doc schema. ` public class Address { @Id private String id; private String name; private String type; private String city; } ` My repository looks like as follows: public interface NetworkElementsESRepository extends ElasticsearchRepository<Address, String> { Address findByNameAndCity(String name, String city);} I need to fetch all addresses with name= "B00/A3K/24" in a particular city using following Query. addressRepo.findByNameAndCity(Name,City) . I

问题 Connected to azure-cosmosdb and able to fire default queries like findAll() and findById(String Id) . But I can't write a native query using @Query annotation as the code is not considering it. Always considering the name of the function in respository class/interface. I need a way to fire a custom or native query to azure-cosmos db. ?! Tried with @Query annotation. But not working. List<MonitoringSessions> findBySessionID(@Param("sessionID") String sessionID); @Query(nativeQuery = true,

问题 Goal: create Elasticsearch index aimed to be loaded with 10 million simple documents. Each document is basically "Elastisearch id", "some company id" and "name". Provide search-as-suer-type feature. I could created successfully an index and an analyzer either straight from Postman (curl or any other tool not relying on Spring Data) or during Spring boot initialization. Nevertheless, when I try to use the analizer it seems it is ignored for the one created straight from Postman. So my main

问题 I am new to MongoTemplate. I want to define a org.springframework.data.mongodb.core.query.Query and org.springframework.data.mongodb.core.query.Criteria to fetch the data from a collection which has a complex document structure. This is the document { "_id" : { "SId" : "ANBS", "AssetId" : "ANBS_BS21", "ST" : NumberLong(1479114000) //StartDate }, "ET" : NumberLong(1479117599) //EndDate, "TS" : [ NumberLong(1479114000), NumberLong(1479114600), NumberLong(1479115200), NumberLong(1479115800),

问题 I have domain: class Company { List<Job> jobs; } Is there a way to return nested object from collection like: @Repository public interface CompanyRepository extends MongoRepository<Company, String>{ Job findByJobId(String jobId); } 回答1: I have to make some assumptions about the structure of your Job model, but assuming something like this: public class Job { private String id; // other attributes and methods } ... and assuming that this model is embedded in your Company model, and not

问题 Prior to Kotlin/JPA , I used to write my DAO layer like this : public interface UserDao extends JpaRepository<User,Long> { Optional<User> findBySsn(String ssn); } And in the caller side , if I want to find someone or create user by SSN , I can write this: val user = userDao.findBySsn(value).orElseGet { userDao.save(value) } It works well and looks fluent. But since Kotlin introduces null-safety , there is another idiomatic way (dao still in Java ): public interface UserDao extends
