这里在同一个端口下演示,简单模拟一下
项目结构
pom.xml
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>groupId</groupId> <artifactId>com-tt-web</artifactId> <version>1.0-SNAPSHOT</version> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version>2.5.2</version> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> <version>3.0.3</version> </dependency> </dependencies> </project>
controller
@RestController
public class ControllerTest {
@Autowired
TestClient testClient;
@RequestMapping("feign/h1")
public String hello1(){
System.out.println("hello1来了");
testClient.hh();
return "TestController hello1";
}
@RequestMapping("feign/h2")
public String hello2(){
System.out.println("hello2来了");
return "TestController hello2";
}
@RequestMapping("feign/h3")
public String hello3(){
System.out.println("hello3来了");
return "TestController hello3";
}
}
client
@FeignClient(name = "testClient",url = "localhost:8080")
public interface TestClient {
@RequestMapping("feign/h2")
String hh();
}
main
@SpringBootApplication
@EnableFeignClients
public class MainApplication {
public static void main(String[] args) {
SpringApplication.run(MainApplication.class,args);
}
}
测试 直接浏览器输入：localhost:8080/fegin/h1
访问controller，然后controller来回转，没什么意义就是简单演示一下
