在Java中使用REST API有哪些不同的用例

Question

I have an use case where i need to use rest api to call other system to get some data, as per my understanding i have created a flow of request and things which will be required. But just not sure whether it is right approach.

My UI has some input parameters based on which my rest api will fetch data from external system.

UI --> ManagedBean(Mapped to UI)-->Service Layer-->Business Layer-->Rest API Layer(i format my rest url, and other inputs required here) --> Calls MyCustomController(Implemented using SPring MVC), this will return JSON format data to the Business layer.

So whenever i call RestTemplate.executeService() --> i am calling controller to intercept this incoming request and it will fetch data from external system.

Is it right approach?

If you want to expose a service to your consumer then providing a web service is a better option.

Multiple ways to develop web service SOAP, REST, etc.

I find REST light weight, intuitive, easy to implement compared to SOAP.

In your case you said JSON format data to business layer. I believe you will be marshalling that into JAVA object for ease of use and good practice.
