JHipster serves as a tool to generate applications, giving you the flexibility to customize the code according to your requirements. In response to your specific inquiry, one approach in Angular involves utilizing 2 entity services to showcase their data within the same view. Alternatively, you can make adjustments to one entity or its DTO to incorporate related entities, or create a new REST resource that combines information from both entities.
Typically, the default fetch mode is set to lazy loading. If you aim to load related entities, refer to the Spring Data documentation on @EntityGraph. Once the object is loaded, ensure proper JSON serialization with the use of the @JsonManagedReference Jackson annotation.
