如何创建链接seo与sem的区别与联系
原理
Spring的HTTP 服务接口是一个带有@HttpExchange方法的 Java 接口，它支持的支持的注解类型有：
- @HttpExchange：是用于指定 HTTP 端点的通用注释。在接口级别使用时，它适用于所有方法。
- @GetExchange：为 HTTP GET请求指定@HttpExchange。
- @PostExchange：为 HTTP POST请求指定@HttpExchange。
- @PutExchange：为 HTTP PUT请求指定@HttpExchange。
- @DeleteExchange：为 HTTP DELETE请求指定@HttpExchange。
- @PatchExchange：为 HTTP PATCH请求指定@HttpExchange。
示例：访问远程接口https://api.chucknorris.io/jokes/random
第一步：添加依赖
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
第二步：配置类
@Configuration
public class HttpConfig {@Beanpublic WebClient webClient() {return WebClient.builder().baseUrl("https://api.chucknorris.io/").build();}@Beanpublic ChuckNorrisService postClient(WebClient webClient) {HttpServiceProxyFactory httpServiceProxyFactory =HttpServiceProxyFactory.builder(WebClientAdapter.forClient(webClient)).build();return httpServiceProxyFactory.createClient(ChuckNorrisService.class);}
}
第三步：远程Service
@HttpExchange(url = "/jokes")
public interface ChuckNorrisService {//https://api.chucknorris.io/jokes/random@HttpExchange(url = "/random", method = "GET")//@GetExchange("/reduct")String reduct();}
第四步：Controller中使用远程Service
@RestController
@RequestMapping("/order")
public class OrderController {@Resourceprivate ChuckNorrisService chuckNorrisService;@GetMapping("/create")public String create() {System.out.println("下单成功！");//扣除库存String stockMsg = chuckNorrisService.reduct();return "order add success -- " + stockMsg;}}
