如何在 Java API 的 URI 中使用与 Go 相同的 `/{id}/class` 动态 ID？

Question

I use gorilla mux for Go for creating the API's

/{id}/class

and I can get the id using

Vars := mux.Vars(r)["id"]

then how can I create the same API in Java Spring?

I use spring to serve Java APIs

<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>3.0.5.RELEASE</version>
</dependency>

server.createContext("/{id}/class", new Class());

the above doesn't work and how to do that?

Answer 1

your question is somewhat misleading. I hope i have interpreted it correctly. I believe you want to define an API with path "/{id}/class", and fetch value of "{id}" in code.

If so, then it can achieved using below:

// Any request type
@Path("/{id}/class")
public void methodA(@PathParam("id") Integer idPassedInUrl) {
// code here
}

And to call this URL, just do it like "/1/class" or "/2/class".

Let me know if you still face any issues.
