    github action or jenkins which is more demand 2025????as fresher which one learn to standout in company???????????

    • @proofofconceptcode
      @proofofconceptcode Месяц назад

      There is nothing like demanding in IT. Companies use these technologies as per their convenience. So you can learn any one ci/cd tech and you can able to use other ones as well, as all are same, its all about writing ci/cd scripts. Like in GitHub we create workflows, which is nothing but yml file, similiary in bamboo(bitbucket) also, we uses yml file. In jenkins, we use jenkins script. And regarding other features, all are having same features. Talking about what most companies are using, so if the project is stored in GitHub they use GitHub action, if projects stored in Bitbucket, they use Bamboo, if projects stored in GitLab, they use GitLab pipeline. And for legacy projects companies use Jenkins. Talking about what to learn to standout as a fresher, so I would recommend pick one cicd framework like GitHub action and understand how it works. How we create steps and jobs. And once you mastered it. Try other frameworks as well.

  • @qwertasdfg575
    @qwertasdfg575 3 месяца назад

    Hello, I have a doubt You are mentioning the query annotations and the sql query init explicitly but while using jpa repository we can directly use the named methods to get the data like geyEmployeeByAdress without mentioning the query explicitly right? Correct me if i am wrong

    • @proofofconceptcode
      @proofofconceptcode 3 месяца назад

      Good catch!! Yes you are partially correct. While using JPA we don't have in built methods like getEmployeeByAddress. However we only have getEmployeeById becoz Id is our primary key. But can use jpa conventions for method name like, public interface EmployeeRepository extends JpaRepository<Employee, Long> { Employee findByAddress(String address); } And also we can achieve the same using @query annotations. It's up to you. I prefer @query annotation because it gives us flexibility to modify the query and update the methods as per our need if needed

    Can we handle exceptions in other methods as well using controller advice? Or it is captured only Excetptoions thrown by controller

    • @proofofconceptcode
      @proofofconceptcode 3 месяца назад

      You have to eventually throw exception from child to parent and at the end it should land on controller. Let say if you throw exception in service layer it should come to controller. And controller advice works for exception throws from all the controllers you have created in your application
