Your use-case seems a little odd since you seem to already only load a single student and only the name of it so I'll try to create a more meaningful example you could build on.

First a disclaimer though: I'm coming from a JavaEE background, haven't used Spring in a while and didn't have a chance to actually test the quickly cobbled together approach I'll describe here so please take it with a grain of salt.

Let's assume you have the following service:

class StudentService {
   @Autowired
   StudentRepository repo;     

   List<Student> loadStudents(someCriteria) {
      return repo.loadStudents(someCriteria);
   }
}

To cache each student you could now introduce a new caching service and call it per student. You might be able to put the method into StudentService but I'm not sure Spring would then be able to inject the necessary handling code (maybe through more advanced AOP and byte-code manipulation).

A simple version could look like this:

class StudentCacheService {
  @CachePut( value = "studentCache", key = "#student.id")
  Student cacheStudent(Student student) {
    return student;
  }
}

class StudentService {
   @Autowired
   StudentRepository repo;     

   @Autowired
   StudentCacheService cacheService;     

   List<Student> loadStudents(someCriteria) {
      List<Student> students = repo.loadStudents(someCriteria);

      //cache each student individually
      students.forEach(s -> cacheService.cacheStudent(s));

      return students;
   }
}

Note that there might be more elegant options like handling it in the cache manager etc. but this should get you started.
