EasyRestfulClient

It is java library developed on top of Apache HTTP library and JDK executor framework. It has capability to execute multiple restful requests concurrently in very easy way.

Features

1. Supports HTTP GET and POST methods.
2. Concurrent execution of requests.
3. Auto conversion request and response to JSON and XML formats.
4. Easy Request creation.

Create RestClientManager Object

	RestClientManager restClient=new RestClientManager(3);

Create Request

Depending upon Content_type header value, library converts request java object to either json or xml. Likewise upon Accept header value, library build response either from json or xml response.

GET

    
	Map<String,String> headers=new HashMap<>();
	String requestUrl="http://localhost:8080/getTestPage";
	headers.put(Constant.CONTENT_TYPE, Constant.MEDIATYPE_JSON);
	headers.put(Constant.ACCEPT, Constant.MEDIATYPE_JSON);
	responseClass=Response.class;
	Request request=new GetRequest(requestUrl,headers, responseClass);

POST

      
	Map<String,String> headers=new HashMap<>();
	String requestUrl="http://localhost:8080/getTestPage";
	headers.put(Constant.CONTENT_TYPE, Constant.MEDIATYPE_JSON);
	headers.put(Constant.ACCEPT, Constant.MEDIATYPE_JSON);
	responseClass=Response.class;
	requestBody=new RequestBody();
	Request request=new PostRequest(requestUrl, headers, requestBody, responseClass);

Make Request and Collect Response

	Response response=(Response)restClient.getData(request);

Make multiple concurrent requests

	//  First request	with JSON format  
	requestUrl="http://localhost:8080/getPerson1";
	headers.put(Constant.CONTENT_TYPE, Constant.MEDIATYPE_JSON);
	headers.put(Constant.ACCEPT, Constant.MEDIATYPE_JSON);
	responseClass=Response1.class;
	requestBody=new RequestBody1();
	((RequestBody1)requestBody).setName("postDummyName1");
	Request request1=new PostRequest(requestUrl,headers, requestBody, responseClass);
	  
	// Second request with XML formats
	requestUrl="http://localhost:8080/getPerson2";
	headers.put(Constant.CONTENT_TYPE, Constant.MEDIATYPE_XML);
	headers.put(Constant.ACCEPT, Constant.MEDIATYPE_XML);
	responseClass=Response2.class;
	Request request2=new GetRequest(requestUrl,headers, responseClass);
	  
	// Third request with JSON format
	requestUrl="http://localhost:8080/getPerson3";
	headers.put(Constant.CONTENT_TYPE, Constant.MEDIATYPE_JSON);
	headers.put(Constant.ACCEPT, Constant.MEDIATYPE_JSON);
	responseClass=Response3.class;
	requestBody=new RequestBody3();
	((RequestBody3)requestBody).setName("postDummyName3");
	Request request3=new PostRequest(requestUrl, headers, requestBody, responseClass);
	  
	List<Request> requests=new ArrayList<Request>();
	requests.add(request1);
	requests.add(request2);
	requests.add(request3);
	  
	List<Object> responses=(List<Object>)restClient.getData(requests);
