如何在 RESTful Web 服务中正确使用 Java 上的 @Path 表示法

Question

@GET
@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
@Path("{idinst: [0-9]+ }/, { tipopersona}/")
public List<String> obtenCorreosDeInstitucion(@PathParam("idinst") long idinst,@PathParam("tipopersona") String tipo){
    List<String> resultado=new ArrayList<>();
    List<Persona> persona=obtenerPersona();
    int length=persona.size();
    int i=0;
    while(i<length){
        if(persona.get(i).getTipoPersona().equals(tipo)){
            if(persona.get(i).getIdInstitucionPersona()==idinst){
                resultado.add(persona.get(i).getEmailPersona());
            }
        }
        i++;
    }
    return resultado;
}

public List<Persona> obtenerPersona(){
    List<Persona> resultado=new ArrayList<>();
    try{
        Query q = em.createQuery("SELECT p FROM Persona p");
        Persona p = (Persona) q.getResultList();
        resultado= (List<Persona>) q.getResultList();
        System.out.println(resultado);

    }
    catch(NoResultException ex){

    }
    return resultado;
}

So I have the code like this, but on the tests, it says 404 not found, but the other methods in this class do pass the tests, so I am assuming something in my path is not right, can someone please point me in the right direction? I have searched up on the internet and I can only find examples for when it's only one variable value you get from the path.

Try the following (it seems to me that you have extra , in your @Path annotation):

@GET
@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
@Path("{idinst: [0-9]+ }/{tipopersona}/")
public List<String> obtenCorreosDeInstitucion(@PathParam("idinst") long idinst,@PathParam("tipopersona") String tipo){
    List<String> resultado=new ArrayList<>();
    List<Persona> persona=obtenerPersona();
    int length=persona.size();
    int i=0;
    while(i<length){
        if(persona.get(i).getTipoPersona().equals(tipo)){
            if(persona.get(i).getIdInstitucionPersona()==idinst){
                resultado.add(persona.get(i).getEmailPersona());
            }
        }
        i++;
    }
    return resultado;
}
