We need help with our Spring Boot backend. We have 2 Entities defined: Client and Dossier. Each client can have multiple dossiers and each dossier can be assigned to one client. Client: @OneToMany(mappedBy = "client", fetch = [login to view URL]) @Getter private List<Dossier> dossiers; Dossier: @ManyToOne @Getter private Client client; We are facing a big problem with data fetching. When we fetch a single client with [login to view URL](uuid); the client is fetched with their dossiers. But we don't want to fetch the dossiers by default. We also created a custom query @Query("SELECT c FROM Client c WHERE [login to view URL] = :uuid"), but also the dossiers are fetched. It looks like [login to view URL] is not working. We want to manage this behaviour, since we are building an application which handles a lot of data and a lot of JOINs. So: by default just fetch the client. If asked, fetch dossiers and other JOINs, like addresses and phone numbers. Database engine: we tried both MySQL and Postgres, but no result. We want to implement clean and less code in our application.

I am a Java developer with experience in Spring Boot, a framework that simplifies the creation and deployment of Spring-based applications. I have used Spring Boot to develop web services, REST APIs, microservices, and cloud-native applications. I have also integrated Spring Boot with various databases, messaging systems, security tools, and testing frameworks. Some of my key achievements using Spring Boot are: - Developed a web service that handles over 10,000 requests per day using Spring Boot, Spring MVC, and Spring Data JPA. - Implemented a REST API that provides data access and manipulation for a mobile application using Spring Boot, Spring HATEOAS, and Spring Security. - Created a microservice that performs complex calculations and communicates with other services using Spring Boot, Spring Cloud, and RabbitMQ. - Deployed a cloud-native application that scales automatically and is resilient to failures using Spring Boot, Spring Cloud, and Kubernetes.
