Sub-resources

In JAX-RS, you can also introduce sub-resource functions in the same resources class. Use the @Path annotation to mark one or more functions to be a sub-resource of the original one; the new path will be relative to the original one. Let's see an example:

@Path("/hello") 
public class FirstRest { 
 
    @Path("/path1") 
    @GET 
    public String testPath1() { 
        return "Hello from path 1!"; 
    } 
 
    @Path("/path2") 
    @GET 
    public String testPath2() { 
        return "Hello from path 2!"; 
    } 
 
} 

As you can see, we have introduced the @Path annotation to the methods testPath1() and testPath2(). The new paths to those methods will be /hello/test1 and /hello/test2 respectively. You can test them using Postman, as we learned earlier.

And, for sure, we can choose the HTTP method of our choice for each of the sub-resource methods, as shown in the following example:

@Path("/hello") 
public class FirstRest { 
 
    @Path("/path1") 
    @GET 
    public String testPath1...
