git代码地址:https://github.com/yixiuquan/Eureka,详细请看EurekaRegisterServiceMaster,EurekaServiceProvider,EurekaServiceConsumer三个项目Eureka服务正常启动,并且服务也可以被发现,

但是使用Feign消费服务却报错,报错信息:java.lang.StackOverflowError: null具体如下:

2017-09-14 17:13:15.621 INFO 13624 --- [nio-8766-exec-1] o.s.web.servlet.DispatcherServlet : FrameworkServlet 'dispatcherServlet': initialization completed in 29 ms

at com.ccs.EurekaServiceService.getUser(EurekaServiceService.java:17) ~[classes/:na]

以下各项目的部分代码
Eureka服务注册中心:
application.xml:

eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
eureka.server.enable-self-preservation=false
eureka.instance.hostname=s1
spring.application.name=master 
server.port=8761
eureka.client.serviceUrl.defaultZone=http://s2:8762/eureka/,http://s3:8763/eureka/

 EurekaRegisterServiceMasterApplication.java:

@EnableEurekaServer
@SpringBootApplication
public class EurekaRegisterServiceMasterApplication {
  public static void main(String[] args) {
   SpringApplication.run(EurekaRegisterServiceMasterApplication.class, args);
  }
}

Eureka服务provider:开启了两个provider端口分别是8764和8765,两个代码都一样只是端口不一样,下面是8764的配置
 application.xml:

eureka.instance.hostname=s4
spring.application.name=serviceprovider 
server.port=8764
eureka.client.serviceUrl.defaultZone=http://s1:8761/eureka/

EurekaServiceProviderApplication.java:

@SpringBootApplication
@RestController
@EnableDiscoveryClient
@RequestMapping(value="/v1",produces="application/json") 
public class EurekaServiceProviderApplication {
    @Value("${server.port}") 
    private String port; 
    public static void main(String[] args) {
        SpringApplication.run(EurekaServiceProviderApplication.class, args);
  }
    @RequestMapping(value="/getUser/{str}",method={RequestMethod.GET,RequestMethod.POST})
    public User getUser(@PathVariable("str") String str){
        User vo = new User();
        String id = str.split(",")[0];
        String name = str.split(",")[1];
        vo.setId(id);
        vo.setName(name);
        vo.setPort(port);
        return vo;
    }
}                            

Eureka服务consumer:
 application.xml:

eureka.instance.hostname=s5
spring.application.name=serviceconsumer
server.port=8766
eureka.client.serviceUrl.defaultZone=http://s1:8761/eureka/

EurekaServiceConsumerApplication.java:

@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
public class EurekaServiceConsumerApplication {
    public static void main(String[] args) {
        SpringApplication.run(EurekaServiceConsumerApplication.class, args);
    }
}

EurekeServiceInterface.java:

@FeignClient("serviceprovider")
public interface EurekeServiceInterface {
    @RequestMapping(value="/v3/getUser/{str}",method=RequestMethod.GET)
    public User getUser(@PathVariable("str") String str);
}

EurekaServiceService.java:

复制代码
@RestController
public class EurekaServiceService {
    @Autowired
    EurekaServiceService eurekaServiceService;

    @RequestMapping(value="/v2/getUser/{str}",method=RequestMethod.GET)
    public String getUser(@PathVariable("str") String str){
        return eurekaServiceService.getUser(str);
    }
}

经QQ群大佬指点,我在EurekaServiceService里面居然引入了自己EurekaServiceService,导致调用时出现递归从而导致栈溢出,将引入的EurekaServiceService改为EurekeServiceInterface就好了,虽然很又爆了com.netflix.client.ClientException: Load balancer does not have available server for client: serviceprovider
public class EurekaServiceService {
  @Autowired
EurekaServiceService eurekaServiceService;

  @RequestMapping(value="/v2/getUser/{str}",method=RequestMethod.GET)
  
public String getUser(@PathVariable("str") String str){

return eurekaServiceService.getUser(str);
   }
}
