Multiple requestmapping value with path variables

Question

@RequestMapping(value = {\"/abcd\", \"/employees/{value}/{id}\"})
public String getEmployees(
      @PathVariable(value = \"value\") String val, 
      @PathVariable(val         


        

Answer 1

I had a similar problem and I found this solution:

@GetMapping(value = {"/clients/page", "/clients/page/{page}"})
public Page index(@PathVariable Optional page) {
   PageRequest pageRequest = page.map(integer -> PageRequest.of(integer, 4))
   .orElseGet(() -> PageRequest.of(0, 4));
      return clientService.showAll(pageRequest);
}

Intellij helped me to get this kind of compact result. Although Intellij throw this message:

''Reports any uses of java.util.Optional, java.util.OptionalDouble, java.util.OptionalInt, java.util.OptionalLong or com.google.common.base.Optional as the type for a field or a parameter. Optional was designed to provide a limited mechanism for library method return types where there needed to be a clear way to represent "no result". Using a field with type java.util.Optional is also problematic if the class needs to be Serializable, which java.util.Optional is not. ''

To be honest, I'm new in this business and I don't understand clearly what the IDE is telling me. If someone with more expertise could help to clarify that message would be great.
