SpringBoot之Consuming a RESTful Web Service

程序通过org.springframework.web.client.RestTemplate调用REST服务，这里REST服务使用

省去maven搭建项目与model类部分，主要代码如下：

package consume.restfull.web.service.hello;import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.client.RestTemplate;@SpringBootApplication
public class Application implements CommandLineRunner {private static final Logger log = LoggerFactory.getLogger(Application.class);public static void main(String[] args){SpringApplication.run(Application.class, args);}@Overridepublic void run(String... arg0) throws Exception {RestTemplate restTemplate = new RestTemplate();Quote quote = restTemplate.getForObject("", Quote.class);log.info(quote.toString());}
}

说明：

RestTemplate makes interacting with most RESTful services a one-line incantation.

The Jackson JSON processing library is in the classpath, RestTemplate will use it (via a message converter) to convert the incoming JSON data into a Quote object.

RestTemplate supports other HTTP verbs such as GET, POST, PUT, and DELETE.
