感谢其中一个答案，我找到了如何使用 postForObject 从带有 Spring 的 POST 获取响应

Thanks to one of answers i've figured out how get the response from a POST with Spring by using the postForObject

String result = restTemplate.postForObject(API_URL + "account/authenticate/?email="+ AUTH_USER +"&token="+ AUTH_PASS, null, String.class);

出于某种原因，我不能在 MAP 中使用参数，而必须将它们内嵌在 URL 中.但这对我来说很好.

For some reason i can't use arguments with MAP and have to put them inline in URL. But that's fine for me.
