问题相关代码，请勿粘贴截图

eureka的yml

server:
  port: 7001
eureka:
  instance:
    hostnamhttps://img-mid.csdnimg.cn/release/static/image/mid/ask/398210863146177.png "#left")
e: eureka7001.com  # eureka实例的主机名
  client:
    register-with-eureka: false #不把自己注册到eureka上
    fetch-registry: false #不从eureka上来获取服务的注册信息
    service-url:
      #      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
      #集群
      defaultZone: http://eureka7002.com:7002/eureka/,http://eureka7003.com:7003/eureka/

服务的提供者的yml

server:
  port: 8001
#spring:
#  application:
#    name: provider-ticket

spring:
  application:
    name: PROVIDER-TICKET #同一服务名称要一致PROVIDER-TICKET
  datasource:
    username: root
    password: 123
    url: jdbc:mysql://localhost:3306/cloud?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC
    driver-class-name: com.mysql.jdbc.Driver

mybatis:
  mapper-locations: classpath:mapper/*Mapper
  type-aliases-package: com.example.pojo

eureka:
  instance:
    prefer-ip-address: true # 注册服务的时候使用服务的ip地址
  client:
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka/,http://eureka7002.com:7002/eureka/,http://eureka7003.com:7003/eureka/
#      fetch-registry: true        #表示客户端是否从 Eureka Server 获取实例注册信息

提供者的controller

@RestController
@RequestMapping("/ticket")
public class TicketController {

    @Autowired
    TicketService ticketService;
    @GetMapping("/selectAll")
    public List<Ticket> getTicket() {
        return ticketService.selectAll();
    }
    @PostMapping("/insertTicket")
    public boolean insertTicket() {
        return ticketService.insertTicket();
    }

    @GetMapping("/getTicket/{id}")
    public Ticket getTicket(@PathVariable("id") long id){
        return ticketService.getTicket(id);
    }
}

消费者的yml


server:
  port: 8081

spring:
  application:
    name: consumer-user

eureka:
  instance:
    prefer-ip-address: true # 注册服务的时候使用服务的ip地址0
  client:
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka/,http://eureka7002.com:7002/eureka/,http://eureka7003.com:7003/eureka/
#    register-with-eureka: false

消费者的controller

@RestController
@RequestMapping("/consumer")
public class UserController {

    @Autowired
    private RestTemplate restTemplate;

    private static final String PREFIX = "http://PROVIDER-TICKET";
    @RequestMapping("/select")
    public List<Ticket> selectTicket() {
        //此参数为注册在Eureka中的服务
        //获取实体类
        //restTemplate.getForEntity();
        return restTemplate.getForObject(PREFIX+"/ticket/selectAll", List.class);//"http://PROVIDER-TICKET/ticket/selectAll"
    }
    @RequestMapping("/insert")
    public boolean insertTicket(Ticket ticket){
        return restTemplate.postForObject(PREFIX+"/ticket/insertTicket",ticket, Boolean.class);
    }

    @RequestMapping("/get/{id}")
    public Ticket getTicket(@PathVariable("id") Long id){
        return restTemplate.getForObject(PREFIX+"/ticket/getTicket/"+id,Ticket.class);
    }
    @RequestMapping("/fulian")
    public String ticket(){
        return "妇联4";
    }
}
