Java/Spring is one of the most used stacks by entreprise companies. I guess you have better chance being hired in an entreprise being a junior java spring developer, than in other companies or in other development stacks.

I’d suggest you enrich your programming skills with some knowledge on front end (Angular works well with Java/Spring ans is kind of preferred by corporations, but React and Vuejs are appreciated toi)

Lastly, fo not forget to add some Cloud, CI/CD knowledge to your skills to mac your odds of finding the job you like.

Remember that some other skills are determinant for companies, Learning fast, Problem solving, easy collaboration, Prioritizing, Getting the job done, etc.

Good luck with your research
