• 与springboot整合的三种方式


    前期准备

    创建两个springboot工程,分别为服务提供者和服务消费者,再创建一个maven project 的公共API

    公共API

    bean

    package com.atguigu.gmall.bean;

            this.userAddress = userAddress;

            return consignee;

        public void setConsignee(String consignee) {
            this.consignee = consignee;
        }
    
        public String getPhoneNum() {
            return phoneNum;
        }
    
        public void setPhoneNum(String phoneNum) {
            this.phoneNum = phoneNum;
        }
    
        public String getIsDefault() {
            return isDefault;
        }

    三种整合方式

    (1)导入dubbo-starter,在application.properties中配置属性,使用@Service【暴露服务】,使用@Reference 【引用服务】,只能配置接口层级

      实现方式就是前期准备中的demo.

    (2)保留dubbo xml 配置,通过@ImportResource 引入配置,可以配置方法级别

          保留 provider.xml ,使用@ImportResource 导入。示例:

      

    package com.atguigu.gmall;
    
    import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.annotation.ImportResource;
    
    //@EnableDubbo
    @ImportResource(locations = "classpath:provider")
    @SpringBootApplication
    public class BootUserServiceProviderApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(BootUserServiceProviderApplication.class, args);
        }
    
    }

    然后注释application.properties 中的属性配置。

      

    (3)使用注解API的方式

      API 配置类示例

    package com.atguigu.gmall.config;
    
    import com.atguigu.gmall.service.UserService;
    import org.apache.dubbo.config.*;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    import java.util.ArrayList;
    import java.util.List;
    
    @Configuration
    public class MyDubboConfig {
    
        @Bean
        public ApplicationConfig applicationConfig(){
            ApplicationConfig applicationConfig = new ApplicationConfig();
            applicationConfig.setName("boot-user-service-provider");
            return applicationConfig;
        }
    
        @Bean
        public RegistryConfig registryConfig(){
            RegistryConfig registryConfig = new RegistryConfig();
            registryConfig.setProtocol("zookeeper");
            registryConfig.setAddress("127.0.0.1:2181");
            return registryConfig;
        }
    
        @Bean
        public ProtocolConfig protocolConfig(){
            ProtocolConfig protocolConfig = new ProtocolConfig();
            protocolConfig.setName("dubbo");
            protocolConfig.setPort(20880);
            return protocolConfig;
        }
    
        @Bean
        public ServiceConfig<UserService> userServiceServiceConfig(UserService userService){
            ServiceConfig<UserService> userServiceServiceConfig = new ServiceConfig<>();
            userServiceServiceConfig.setInterface(UserService.class);
            userServiceServiceConfig.setRef(userService);
            userServiceServiceConfig.setVersion("1.0.0");
    
            MethodConfig methodConfig = new MethodConfig();
            methodConfig.setName("getUserAddressList");
            methodConfig.setTimeout(1000);
            List<MethodConfig> list = new ArrayList<>();
            list.add(methodConfig);
            userServiceServiceConfig.setMethods(list);
    
            return userServiceServiceConfig;
        }
    }

      启动类

      

    package com.atguigu.gmall;
    
    import org.apache.dubbo.config.spring.context.annotation.DubboComponentScan;
    import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.annotation.ImportResource;
    
    //@EnableDubbo
    //@ImportResource(locations = "classpath:provider")
    @DubboComponentScan("com.atguigu.gmall")
    @SpringBootApplication
    public class BootUserServiceProviderApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(BootUserServiceProviderApplication.class, args);
        }
    
    }
