SpringCloud整合Nacos（2.服务注册）

1.服务提供者模块

1.1 新建bootstrap.yml启动配置

server:
  port: 9001
spring:
  application:
    name: module-abc  #作为服务feign的value
  profiles:
    active: dev
  cloud: 
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848

1.2 新建服务提供者逻辑：

@RestController
@RequestMapping("/sample")
public class SampleController{
    @GetMapping(value="/label")
    public String getLabel(@RequestParam("id") Integer id) {
        return id==0?"zero":"nonZero";
    }
}

此时可以启动该服务，测试api的正确性

2.服务消费者模块

2.1新建消费者服务接口

@FeignClient("module-abc") // 此处的module-abc即为服务提供者的模块名
@RequestMapping(value="/sample")
public interface ISampleController {
    @GetMapping(value = "/label")
    String getLabel(@RequestParam("id") Integer id);
}

 

2.2新建bootstrap.yml启动配置

spring:
  application:
    name: main
  profiles:
    active: dev
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848

 

2.3 修改消费者启动文件

添加   @EnableFeignClients 注解，同时指定接口发现的报地址   basePackages = "com.zhiscity.framework.users.microapi"

@EnableDiscoveryClient
@SpringBootApplication
@EnableFeignClients(basePackages = "com.zhiscity.framework.users.microapi")//此处要指定服务接口的包地址
@EnableHystrixDashboard//开启断路器监控
@EnableCircuitBreaker//开启断路器监
@EnableTransactionManagement
@ServletComponentScan
@MapperScan(basePackages = "com.zhiscity.framework.users.dao")
public class UsersApplication {

    private static final Logger logger = LoggerFactory.getLogger(UsersApplication.class);

    public static void main(String[] args) {
        logger.info("\r\n=====================服务启动start=====================");
        SpringApplication.run(UsersApplication.class, args);
        logger.info("\r\n=====================服务启动end=====================");
    }
}

2.4 通过接口调用服务

@RestController
@RequestMapping("/users")
public class Usercontroller {
    @Resource
    private ISampleController sampleController;
 
    @RequestMapping("/{id}")
    public String text(@PathVariable Integer id) {
        return sampleController.getLabel(id);
    }
}

通过以上的配置后，可以测试服务注册和使用
