1.对于调用的http,只要能访问即可:
2、访问端,也就是spring-cloud端。
A、在工程启动类名前加入@EnableFeignClients注解:如下图:
@SpringBootApplication @EnableFeignClients public class VisualintercomAppServiceApplication extends SpringBootServletInitializer {
B、加入依赖:
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-feign</artifactId> </dependency>
C、调用业务类:
@RestController @RequestMapping("user") public class SocketController { @Autowired private FeignService feignService;
@RequestMapping(value = "list",method = RequestMethod.GET) public String getData() { return feignService.getData(); } }
E、通过接口结合FeignClient访问外网http接口类。
@FeignClient(name = "baidu",url = "http://192.168.0.194:8082") public interface FeignService { @RequestMapping(value = "/feign/data", method = RequestMethod.GET) public String getData(); }
注意:外网的地址:http://192.168.0.194:8082//feign/data ,当有参数时在函数体中加入参数:StringgetData(@RequestParam( "q" ) String queryStr);。
名字和IP:端口可在application.properties中配置:
svc.url=http://192.168.0.194:9205 svc.name=scp-videointercom-component
然后在接口中调用如:
@FeignClient(name = "${svc.name}",url = "${svc.url}") public interface FeignService { @RequestMapping(value = "/user/list", method = RequestMethod.GET) public String getData(); }
