问题描述
我上课

// org.springframework.web.client.RestTemplate
RestTemplate的用途是什么?
What is RestTemplate used for?
推荐答案
我假设您了解spring模板的概念. (基于具有相同名称的设计专利). RestTemplate是用于进行HTTP REST调用(REST客户端)的模板.
I assume you understand the concept of templating in spring. (its based on a design patten with the same name). RestTemplate is a template used to make HTTP Rest Calls (REST Client).
如果要进行HTTP调用，则需要创建HttpClient，传递请求和(或)表单参数，设置接受标头并执行反编组(全部由Spring Rest模板自行完成)，从您那里提取所有这些详细信息.
If you want to make a HTTP Call, you need to create a HttpClient, pass request and (or) form parameters, setup accept headers and perform unmarshalling of response, all by yourself, Spring Rest Templates, tries to take the pain away by abstracting all these details from you.
