nacos ribbon restTemplate 没有生效

@Configuration
public class BeanConfig {

    @LoadBalanced
    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }
}

 

    @Autowired
    RestTemplate restTemplate;


//    @Resource
//    private LoadBalancerClient loadBalancerClient;
    @RequestMapping("/order-hello")
    public Object orderHello(){
//        ServiceInstance serviceInstance = loadBalancerClient.choose("logistics");
//        return serviceInstance==null?"null":serviceInstance.getHost()+serviceInstance.getPort();
        return restTemplate.getForObject("http://order"+"/api/hello",String.class);
        //  return null;
        // return restTemplate.getForObject("http://127.0.0.1:8080"+"/api/hello",String.class);
    }

 报错如下

发现问题了

springcloud 莫个版本后不支持ribbon 了，需要导入下面这个包，而且要是正确的版本。

    <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-loadbalancer</artifactId>
            <version>4.0.1</version>
        </dependency>
