本文介绍了一个使用 Java 实现 RESTful API 调用的例子，包括 POST 和 GET 请求的处理方式。展示了如何利用 RestTemplate 发送 JSON 数据，并获取响应结果。

public class RestClient {
private static final RestTemplate temp = new RestTemplate();

private static void validateDeal() throws Exception {

HttpEntity<String> entity = ClientHelper.getHttpEntity(form.toJsonString());

ResponseEntity<String> output = temp.postForEntity("url_string", entity, String.class);
List<MyObject> results = JsonConverter.convert(output.getBody(), new TypeReference<List<MyObject>>(){});

System.out.println(results);
}

private static Portfolio getPortfolio(String uid, String code) throws Exception {
ResponseEntity<String> output = temp.exchange("/test_url?uid=" + uid + "&code=" + code), HttpMethod.GET, ClientHelper.getHttpEntity(String.class), String.class);
List<MyObject> results = JsonConverter.convert(output.getBody(), new TypeReference<List<MyObject>>(){});
}

}

public final class ClientHelper {
public static<T> HttpEntity<T> getHttpEntity(T object){
HttpEntity<T> entity = new HttpEntity<T>(object, getHeaders());
return entity;
}

public static<T> HttpEntity<T> getHttpEntity(Class<T> clz){
HttpEntity<T> entity = new HttpEntity<T>(getHeaders());
return entity;
}
}
