Springboot集成dubbo使用nacos作为服务注册订阅

1. 在nacos已经存在的情况下，springboot配置dubbo集成，pom引入依赖包

0.2.1.RELEASE
        0.2.1
        2.6.5
        0.0.1
        1.0.2

            com.alibaba
            dubbo
            ${dubbo.version}
        
        
            com.alibaba
            dubbo-registry-nacos
            ${dubbo-registry-nacos.version}
        
        
            com.alibaba.spring
            spring-context-support
            ${dubbo-spring-context-support.version}
        
        
        
        
            com.alibaba.boot
            dubbo-spring-boot-starter
            ${dubbo-spring-boot-starter.version}
            
                
                    com.alibaba
                    dubbo
                
            
        
        
            com.alibaba.boot
            nacos-discovery-spring-boot-starter
            ${nacos-discovery-spring-boot-starter.version}
        

工程application.yml配置dubbo，nacos相关信息
dubbo:
application:
name: 应用名
version: 版本说明
registry:
address: nacos://ip:8848
scan:
base-packages: xxxx.service
protocol:
name: dubbo
port: 20880
定义注册的接口

@Service
public interface IFileService {
	public Map storageFile(String businessType, String fileName,
			String corpCode, byte[] fileData, String systemType)
			throws Exception;
			}

调用接口的类注入上述接口
import com.alibaba.dubbo.config.annotation.Reference;
@Reference
private IFileService fileService;

2. springboot使用hessian实现rpc，无须服务注册和服务发现，使用http方式发布接口和调用接口
   引入依赖

   com.caucho
    hessian
    4.0.51

服务提供方

@Bean(name = "/rpc/appRedisService")
	public HessianServiceExporter appRedisService() {
		HessianServiceExporter exporter = new HessianServiceExporter();
		exporter.setService(appRedisServiceImpl);
		exporter.setServiceInterface(IRedisAppService.class);
		return exporter;
	}

服务调用方

@Bean
  public HessianProxyFactoryBean redisRpcClient() {
    HessianProxyFactoryBean hessianProxyFactory = new HessianProxyFactoryBean();
    hessianProxyFactory.setServiceUrl("http://IP:port/rpc/redisService");
    hessianProxyFactory.setServiceInterface(IRedisService.class);
    return hessianProxyFactory;
  }
