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。html
经过RestTemplate消费服务,须要先context中注册一个RestTemplate bean。代码以下:spring
@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()); }; }
运行程序,控制台打印:api
{ “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.” } }
