Question

DiscoveryClient还需要什么？我正在尝试使用DiscoveryClient将注册服务提取到eureka。独立程序运行良好，但以下代码片段将与在jboss上运行的Web应用程序集成。

这是代码 - DiscoveryClientController.java

`import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.discovery.DiscoveryClient;
import org.springframework.stereotype.Controller;
@Controller
public class DiscoveryClientController {

    @Autowired
    private DiscoveryClient discoveryClient;


    public DiscoveryClient getClient(){

        return discoveryClient;
    }
}`

DiscoveryClientBean.java

 import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class DiscoveryClientBean{


    @Bean
    public  DiscoveryClientController  discoveryClientController()
    {
        return  new DiscoveryClientController();
    }

}

Answer 1

异常告诉您缺少类型org.springframework.cloud.client.discovery.DiscoveryClient的spring bean的定义。在这种特殊情况下，您不必自己定义一个，但必须在@EnableDiscoveryClient带注释的类上使用@SpringBootApplication注释启用它。

如果您需要更多详细信息，请花点时间阅读Service Registration and Discovery

没有类型为“org.springframework.cloud.client.discovery.DiscoveryClient＆＃39;”的合格bean可得到
