建立一个springboot工程,去消费RESTFUL的服务。这个服务是 http:///gturnquist-quoters.cfapps.io/api/random ,它会随机返回Json字符串。
在Spring项目中,它提供了一个很是简便的类,叫RestTemplate,它能够很简便的消费服务。spring
经过RestTemplate消费服务,须要先context中注册一个RestTemplate bean。代码以下:api
@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
return builder.build();
}
@Bean
public CommandLineRunner run(RestTemplate restTemplate) throws Exception {
return args -> {
String quote = restTemplate.getForObject(
"http://gturnquist-quoters.cfapps.io/api/random", String.class);
log.info(quote.toString());
};
}复制代码
运行程序,控制台打印:springboot
{
“type”: “success”,
“value”: {
“id”: 6,
“quote”: “It embraces convention over configuration, providing an experience on par with frameworks that excel at early stage development, such as Ruby on Rails.”
}
}复制代码
