  • Spring Boot allows you to create Entities that reflect your business model and database, external to your service logic you should not expose those unique properties. In the case of transferring information out to an API for example you should map the contents to a DTO (Data Transfer Object) that may not be exactly what your business entity shape looks like. For example elements like passwords should be excluded and computed properties may not be part of your entities but can be part of your DTO objects.
    Learn how to use Mappers in Spring Boot and isolate and add a loosely coupled interfaces that does not break as code changes.

    Great video, would love to see more materials on Spring. Personally using mapstruct mapper, quite easy to use and seems to have less boilerplate code. Thank you for this video

    Is the reason you created the mapperconfig(modelmapper) to do it as a singleton?

    • @fastandsimpledevelopment
      @fastandsimpledevelopment  Před rokem +4

      Yes, Sprint Beans are Singletons by default so no overhead in creating each mapper objects at runtime after the initial bean creation

    some advice: I have to spend 18/20 minutes to watch you typing all basic spring stuff, and only 2 minutes to talk about modelmapper, which is also very basic.. I'd rather see you go deeper with this library and instead of watching your typing, just put those controller, service files there already and explain them instead..

    Omg, why do not you use record UserDto, bro?

    • @fastandsimpledevelopment

      This is based on Java 8, records where introduced in Java 14. Java 8 is still used by 99% of the companies I work with.

      @@gasparcalix2095 You can not move from Java 8 to anything else and get Oracle support without paying, Banks and Insurance companies do not want to pay for Java. Open JDK does not pass security standards yet. Same issue with Spring Boot 3, you really need a newer version of Java but no one is making the commitment yet and changing out of older dependencies is hard. We still have more years of Java 8 - End of Life March 2025!

    Converter between User and UserDTO should do Controller layer, not Service layer :)

    • @MaxxAF
      @MaxxAF Před rokem

      why should the convert be done in the Controller layer, not Service layer? I'm learning about and I don't know what the best practice is.

    • @fastandsimpledevelopment
      @fastandsimpledevelopment  Před rokem +5

      I think it is a bit of religion, I like it in the service so all the business type logic is 100% isolated from the Controller and any other part of the application that needs the processing can call it in the Service. If your creating Lambdas you may not have a Rest Controller but still need the Converter / Mapper logic to be used

    • @gasparcalix2095
      @gasparcalix2095 Před rokem +6

      no!
      the contoller must be the simplest as possible

    • @youssefbouchara1179
      @youssefbouchara1179 Před rokem +6

      nop, any logic should be out of the controller! The controller is only there to return a response back.

    • @johndoedoejohn
      @johndoedoejohn Před rokem

      Controller layer needs to get the data and pass it to another layer without any logic involved.

    That's work just great. Thank you! Im wondering if you can go deep inside modelMapper and do relationships like @OneToMany, @ManyToMany. Im having some errors using model mapper with relationships. :(
