Nested context paths

[ikhoon]

Currently, a context path is only supported at the root path.
Nested context paths will help group and isolate each service.

sb.contextPath("/rest")
      .contextPath("/catalog")
          .service("/product", new GetProductService())
          .service("/products", new ProductsHandler())
          .and()
      .contextPath("/cart")
          .service("/checkout", new CheckoutService());
          ... 
          .and()
      .and()
  .contextPath("/gql")
      .service("/catalog", new GraphQLService());

Hello @ikhoon nim.
May i look at this issue?

I understood it like this. is my understanding correct?

• /rest/catalog/product => getProductService()
• /rest/catalog/products => productsHandler()
• /rest/cart/checkout => checkoutService()
• /qql/catalog => GraphQLService()

If we use and() to go back 1-depth before,
I think it will cause breakpoints.

From now, and() return Generic <T>. In most case, Generic <T> is ServerBuilder Type.
However, contextPath() will returns ContextPathServiceBuilder type.
Thus, it will make breaking change.

How about before() or previous() instead of using and() generally to go back 1-depth before?
I think, in that way, user will not encounter braking changes.

For Example,

sb.contextPath("/rest")
      .contextPath("/catalog")
          .service("/product", new GetProductService())
          .service("/products", new ProductsHandler())
          .before()
      .contextPath("/cart")
          .contextPath("/foo")
               .contextPath("/bar")
                    .service("/checkout", new CheckoutService());
                    .and()
  .contextPath("/gql")
      .service("/catalog", new GraphQLService());

• /rest/catalog/product => getProductService
• /rest/catalog/products => productsHandler
• /rest/cart/foo/bar/checkout => checkoutService
• /gql/catalog => GraphQLService.
