We need to call several service in our application by RestTemplate. like this:

• abc.test/api_one/
• abc.test/api_one/
• egf.test/api_alpha/
• egf.test/api_beta/
• xyz.test/api_a/

There are three opinion in team.

1. Single instance for all of them.
2. Instance per Endpoints (abc.test, egf.test, xyz.test)
3. Instance per APIs

I think the answer is dependent on situation, so question is how to determine ? What kinds of element should we based on ?

CodePudding user response：

RestTemplate is thread-safe. It makes sense to create as many instances as many different configurations (for example different message converters) you have.

CodePudding user response：

You can use single api is enough using with @PathVariable

@PathVariable is a Spring annotation which indicates that a method parameter should be bound to a URI template variable.

@RequestMapping(path="/{name}}")

name - name of the path variable to bind to request

Dependents on request your pathvaraible name is aliased with api_alpha,api_beta....like egf.test/api_aplha

Single request if you wants to invoke all of above

@RequestMapping(path="/{param1}/{param2}")

In your case @RequestMapping(path="egf.test/{name1}/{name2}")and request url like /egf.test/api_aplha/api_beta

Inside your controller class like this

@RestController
public class MyController {
@RequestMapping(path="/{name}/{name2}")
public <returnType> getTestInvoke(@PathVariable("name") String name, 
        @PathVariable("name2") String name2) {
  ...
    return <returntype>;
 }
}
