>            接下来，介绍一下Dubbo与SpringBoot的三种zhen整合方式,详细的介绍，我都写在代码里面了。

### **一、服务提供方 ** ###

1.  首先先看SpringBoot的Application启动应用,代码如下：

package com.nyist.produce;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.annotation.ImportResource;
    
    import com.alibaba.dubbo.config.spring.context.annotation.DubboComponentScan;
    import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
    /**
     * 
     * @author lhg
     *
     */
    /**
     * Spring Boot与Dubbo整合的三种方式:
     * 	1.导入dubbo-starter,在application.properties配置属性,使用@Service【暴露服务】 使用@Reference 来引用服务
     *  2.保留dubbo xml配置文件,使用@ImportResource() 导入dubbo-starter,使用@ImportResource导入dubbo的配置文件即可。
     *  3.使用注解API的方式
     *  	将每一个组件手动创建到容器当中,让Dubbo扫面其他的组件
     * @author lvhaoguang
     *
     */
    //开启基于注解的Dubbo
    //@EnableDubbo          第一种方式下  使用
    //@ImportResource(locations="classpath:provider.xml")     第二种方式使用
    @EnableDubbo(scanBasePackages="com.nyist.produce")
    @SpringBootApplication
    public class BootUserServiceProviderApplication {
    
    	public static void main(String[] args) {
    		SpringApplication.run(BootUserServiceProviderApplication.class, args);
    	}
    
    }

2.第一种方式下dubbo的配置方式:

dubbo:
      application:
        name: boot-user-service-provider  #服务的应用名
      registry:
        protocol: zookeeper     #协议名称
        address: 127.0.0.1:2181 #地址
      protocol:
        name: dubbo             #通信协议名称
        port: 20880             #通信协议端口   
    
      monitor:
        protocol: registry      #监控中心
        
        
      scan:
        base-packages:   包扫描   在配置文件开启包扫面  就不需要使用@EnableDubbo注解了

3.第二种方式下，保留Dubbo.xml配置，使用@ImportResource()导入配置文件，xml配置文件如下：

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    	xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans        
    		http://www.springframework.org/schema/beans/spring-beans-4.3.xsd        
    		http://dubbo.apache.org/schema/dubbo        
    		http://dubbo.apache.org/schema/dubbo/dubbo.xsd">
    
    	1.指定当前服务/应用的名字(同样的服务名字相同,不要和别的服务同名)
    	<dubbo:application name="boot-user-service-provider"></dubbo:application>
    	
    	2.指定注册服务中心的位置
    	<dubbo:registry address="zookeeper://localhost:2181"></dubbo:registry>
    	<dubbo:registry protocol="zookeeper" address="localhost:2181"></dubbo:registry>
    	
    	3.指定通信规则(通信协议,通信规则)
    	<dubbo:protocol name="dubbo" port="20880"></dubbo:protocol>
    
    	4.暴露服务 ref:指定服务的真正实现对象
    	<dubbo:service interface="com.nyist.api.service.UserService" ref="userServiceImpl" version="1.0.0"></dubbo:service>
    	服务的实现
    	<bean id="userServiceImpl" class="com.nyist.produce.serviceImpl.UserServiceImpl"></bean>
    	
    	统一设置服务配置方的级别
    	<dubbo:provider timeout="2000"></dubbo:provider>
    	
    	连接监控中心
    	<dubbo:monitor address="registry"></dubbo:monitor>
    	
    </beans>

4.第三种配置，使用API的方式配置，代码如下：

package com.nyist.produce.config;
    
    import java.util.Arrays;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    import com.alibaba.dubbo.config.ApplicationConfig;
    import com.alibaba.dubbo.config.MethodConfig;
    import com.alibaba.dubbo.config.ProtocolConfig;
    import com.alibaba.dubbo.config.RegistryConfig;
    import com.alibaba.dubbo.config.ServiceConfig;
    import com.nyist.api.service.UserService;
    
    @Configuration
    public class DubboConfig {
    
    	@Bean
    	public ApplicationConfig applicationConfig(){
    		ApplicationConfig applicationConfig = new ApplicationConfig();
    		applicationConfig.setName("boot-orderservice-providers");
    		return applicationConfig;
    	}
    	
    	
    	/**
    	 * <dubbo:registry protocol="zookeeper" address="localhost:2181"></dubbo:registry>
    	 */
    	@Bean
    	public RegistryConfig registryConfig(){
    		RegistryConfig registryConfig = new RegistryConfig();
    		registryConfig.setProtocol("zookeeper");
    		registryConfig.setAddress("localhost:2181");
    		return registryConfig;
    	}
    	
    	/**
    	 * <dubbo:protocol name="dubbo" port="20880"></dubbo:protocol>
    	 */
    	@Bean
    	public ProtocolConfig protocolConfig(){
    		ProtocolConfig protocolConfig = new ProtocolConfig();
    		protocolConfig.setName("dubbo");
    		protocolConfig.setPort(20880);
    		return protocolConfig;
    	}
    	
    	/**
    	 * 
    	<dubbo:service interface="com.nyist.api.service.UserService" ref="userServiceImpl" version="1.0.0"></dubbo:service>
    	
    	<bean id="userServiceImpl" class="com.nyist.produce.serviceImpl.UserServiceImpl"></bean>
    	 */
    	@Bean
    	public ServiceConfig<UserService> userviceConfig(UserService userService){
    		ServiceConfig<UserService> userviceConfig = new ServiceConfig<UserService>();
    		userviceConfig.setInterface(UserService.class);
    		userviceConfig.setRef(userService);
    		userviceConfig.setTimeout(1000);
    		userviceConfig.setVersion("1.0.0");
    		
    		MethodConfig methodConfig = new MethodConfig();
    		methodConfig.setName("getUserAddressList");
    		methodConfig.setTimeout(2000);
    		userviceConfig.setMethods(Arrays.asList(methodConfig));
    		return userviceConfig;
    	}
    	
    	/**
    	 * 
    	<dubbo:provider timeout="2000"></dubbo:provider>
    	
    	
    	<dubbo:monitor address="registry"></dubbo:monitor>
    	 */
    	
    }

５．生产者工程结构目录如下：

### **二、服务消费者** ###

１.同样的服务消费者也是这样，有三配置方式，一下基于第一种配置，配置服务消费者，如下：

dubbo:
      application:
        name: boot-order-service-consumer             #应用的名字
      registry:
        address: zookeeper://127.0.0.1:2181
        
      monitor:
        protocol: registry
     
        
        
    server:
      port: 8081

２.消费者结构目录如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2x2aGFvZ3Vhbmcw_size_16_color_FFFFFF_t_70 1][]

### 三、运行结果 ###

结果如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2x2aGFvZ3Vhbmcw_size_16_color_FFFFFF_t_70 2][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2x2aGFvZ3Vhbmcw_size_16_color_FFFFFF_t_70 5][] ![20190311092002826.png][]
