layout: default title: Demo: Address Show Route

---

We have a list route working that returns all the addresses in our database. But what if we want a single address by its id?

1. Create a second method in your DAO that retrieves a single Address by its id. Assume the id is going to be passed into the method as a parameter.

   public Address findById(int id){
     return em.find(Address.class, id);
   }
   

2. In your controller create a second method called show. This method will take a path of /api/addresses/{id} where is the {id} is a URI parameter (PathVariable).

   @RequestMapping(path="addresses/{id}", method=RequestMethod.GET)
   public Address show(@PathVariable int id){
     return addressDAO.findById(id);
   }
   

3. Run the program and hit the route http://localhost:8080/api/addresses/1 in Postman. View the returned json data. Your should get

   {
     "id": 1,
     "street": "47 MySakila Drive",
     "street2": null,
     "stateProvince": "Alberta",
     "city": "Lethbridge",
     "postalCode": "",
     "phone": "",
     "country": {
       "countryCode": "CA",
       "name": "Canada"
     }
   }
