本文主要介紹了IDEA整合Dubbo+Zookeeper+SpringBoot實現，分享給大家，具體如下：

放上一張Dubbo的架構圖

剛剛學過SpringCloud，Dubbo雖然沒有Spring家族那么強悍，但始終不能違背Dubbo是一款高性能優(yōu)秀的RPC框架。

click官網地址了解更多

自己也是初學者，想自己動手做一個簡單的demo，于是上網查資料，發(fā)現針對那種入門的案例，網上主要有兩個比較經典的，一個是尚硅谷雷神版，還有一個是官網推薦的入門 案例。

雷神的Dubbo視頻教程大神講解

視頻中用的eclipse開發(fā)，習慣IDEA開發(fā)的我們不免手癢想要使用IDEA整合一波。

1. 提出需求

業(yè)務拆分

再次拆分

2. 環(huán)境準備

1. Zookeeper-3.4.14

2. dubbo-admin 可視化管理界面

安裝過程參照雷神視頻，沒什么技術含量

準備好三個SpringBoot模塊

3. 業(yè)務接口整合

這個模塊的主要功能在于分包解耦

UserAddress.java：

public class UserAddress implements Serializable { private Integer id; private String userAddress; private String userId; private String consignee; private String phoneNum; private String isDefault; public Integer getId() {return id; } public void setId(Integer id) {this.id = id; } public String getUserAddress() {return userAddress; } public void setUserAddress(String userAddress) {this.userAddress = userAddress; } public String getUserId() {return userId; } public void setUserId(String userId) {this.userId = userId; } public String getConsignee() {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; } public void setIsDefault(String isDefault) {this.isDefault = isDefault; } public UserAddress(Integer id, String userAddress, String userId, String consignee, String phoneNum, String isDefault) {this.id = id;this.userAddress = userAddress;this.userId = userId;this.consignee = consignee;this.phoneNum = phoneNum;this.isDefault = isDefault; } @Override public String toString() {return 'UserAddress{' +'id=' + id +', userAddress=’' + userAddress + ’’’ +', userId=’' + userId + ’’’ +', consignee=’' + consignee + ’’’ +', phoneNum=’' + phoneNum + ’’’ +', isDefault=’' + isDefault + ’’’ +’}’; }}

OrderService.java

public interface OrderService { //初始化訂單模塊 public List<UserAddress> initOrder(String userId);}

UserService.java

public interface UserService { //消費訂單模塊 public List<UserAddress> getUserAddressList(String userId);}4. 服務提供者

UserServiceImpl.java

@Component@Service //用的是com.alibaba.dubbo.config.annotation.Service,目的是為了在注冊中心暴露服務public class UserServiceImpl implements UserService { @Override public List<UserAddress> getUserAddressList(String userId) {UserAddress userAddress1 = new UserAddress(1,'福建省莆田市','37','劉老師','10086','1');UserAddress userAddress2 = new UserAddress(2,'福建省福州市','33','黃老師','1001','1');List<UserAddress> addresses = new ArrayList<>();addresses.add(userAddress1);addresses.add(userAddress2);return addresses; }}

UserServiceProviderApplication.java

@EnableDubbo //開啟Dubbo @SpringBootApplicationpublic class UserServiceProviderApplication {public static void main(String[] args) {SpringApplication.run(UserServiceProviderApplication.class, args);}}

application.properties

#應用端口server.port=8080#dubbo服務地址dubbo.application.name=user-service-provider#zk注冊中心協議和地址dubbo.registry.protocol=zookeeperdubbo.registry.address=127.0.0.1:2181#通信規(guī)則（通信協議和端口）dubbo.protocol.name=dubbodubbo.protocol.port=20880#連接監(jiān)控中心（這里面我沒有啟動監(jiān)控中心）dubbo.monitor.protocol=registry

pom.xml 新增依賴

<!-- 引入公共API,以實現其接口 --><dependency><groupId>com.liuzeyu</groupId><artifactId>gmall-interface</artifactId><version>0.0.1-SNAPSHOT</version></dependency><!-- 引入spring-boot-starter以及dubbo和curator的依賴 --><dependency><groupId>com.alibaba.boot</groupId><artifactId>dubbo-spring-boot-starter</artifactId><version>0.2.0</version></dependency>5. 服務消費者

OrderController.java

@RequestMapping('order')@Controllerpublic class OrderController { @Autowired private OrderService orderService; @ResponseBody //以json格式返回 @RequestMapping('/initOrder') public List<UserAddress> initOrder(@RequestParam('uid') String userId){List<UserAddress> userAddresses = orderService.initOrder(userId);return userAddresses; }}

OrderServiceImpl.java

@Service //暴露服務@Componentpublic class OrderServiceImpl implements OrderService { //遠程調用服務 @Reference(url = 'dubbo://127.0.0.1:20880') private UserService userService; @Override public List<UserAddress> initOrder(String userId) {return userService.getUserAddressList(userId); }}

@Reference這邊的URL指向需要注意，因為我們的通信協議使用dubbo，地址和端口也必須指明，否則會發(fā)現UserService 注入為null的現象！

OrderServiceConsumerApplication.java

@EnableDubbo@SpringBootApplicationpublic class OrderServiceConsumerApplication {public static void main(String[] args) {SpringApplication.run(OrderServiceConsumerApplication.class, args);}}

application.properties

#dubbo服務名稱dubbo.application.name=order-service-consumer#zk地址dubbo.registry.address=zookeeper://127.0.0.1:2181#監(jiān)控中心配置dubbo.monitor.protocol=registry#這個需要注意,每一個服務的dubbo端口不能沖突dubbo.protocol.port=20881server.port=8081

pom.xml

<!-- springboot web模塊 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>com.liuzeyu</groupId><artifactId>gmall-interface</artifactId><version>0.0.1-SNAPSHOT</version></dependency><!-- 引入spring-boot-starter以及dubbo和curator的依賴 --><dependency><groupId>com.alibaba.boot</groupId><artifactId>dubbo-spring-boot-starter</artifactId><version>0.2.0</version></dependency>6. 測試

DEMO的測試流程應該這樣

搭建ZK環(huán)境

搭建Dubbo可視化管理界面

項目啟動

查看是否服務注冊進來

接口調式

訪問：http://localhost:8081/order/initOrder?uid=33

實現了RPC遠程通信！！

7. 最后附上另外兩種配置文件整合方式7.1 XML整合配置文件

因為SpringBoot屏蔽了大量的XML配置，但是dubbo官方又建議我們使用XML配置，所以整合的最后附上XML配置

consumer.xml

<?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://code.alibabatech.com/schema/dubbo' xsi:schemaLocation='http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd'> <!--定義了提供方應用信息，用于計算依賴關系；在 dubbo-admin 或 dubbo-monitor 會顯示這個名字，方便辨識--> <!-- 對應properties：dubbo.application.name=user-service-provider--> <dubbo:application name='order-service-consumer' owner='lzy' organization='hgfzp'/> <!--使用 zookeeper 注冊中心暴露服務，注意要先開啟 zookeeper--> <!-- 對應properties：dubbo.registry.protocol=zookeeperdubbo.registry.address=127.0.0.1:2181--> <dubbo:registry address='zookeeper://localhost:2181'/> <!-- 用dubbo協議在20880端口暴露服務 --> <!-- 對應properties:dubbo.protocol.name=dubbo dubbo.protocol.port=20880--> <dubbo:protocol name='dubbo' port='20881' /> <!--使用 dubbo 協議實現定義好的 com.liuzeyu.service.UserService 接口--> <!-- 對應@Component @Service注入UserServiceImpl--> <dubbo:service interface='com.liuzeyu.service.OrderService' ref='orderService' protocol='dubbo' /> <!--具體實現該接口的 bean--> <bean /><!-- 配置監(jiān)控中心--> <dubbo:monitor protocol='registry'/></beans>

provider.xml

<?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://code.alibabatech.com/schema/dubbo' xsi:schemaLocation='http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd'> <!--定義了提供方應用信息，用于計算依賴關系；在 dubbo-admin 或 dubbo-monitor 會顯示這個名字，方便辨識--><!-- 對應properties：dubbo.application.name=user-service-provider--> <dubbo:application name='user-service-provider' owner='lzy' organization='hgfzp'/> <!--使用 zookeeper 注冊中心暴露服務，注意要先開啟 zookeeper--> <!-- 對應properties：dubbo.registry.protocol=zookeeperdubbo.registry.address=127.0.0.1:2181--> <dubbo:registry address='zookeeper://localhost:2181'/> <!-- 用dubbo協議在20880端口暴露服務 --><!-- 對應properties:dubbo.protocol.name=dubbodubbo.protocol.port=20880--> <dubbo:protocol name='dubbo' port='20880' /> <!--使用 dubbo 協議實現定義好的 com.liuzeyu.service.UserService 接口--><!-- 對應@Component@Service注入UserServiceImpl--> <dubbo:service interface='com.liuzeyu.service.UserService' ref='userService' protocol='dubbo' /> <!--具體實現該接口的 bean--> <bean /> <dubbo:monitor protocol='registry'/></beans>

如需要啟動測試記住需要注釋掉之前加在接口實現類上面的服務暴露配置

OrderServiceImpl：

UserServiceImpl：

7.2 配置類整合

通過配置自定義配置類注入配置信息

OrderConfig.java 服務提供者使用

@Configurationpublic class OrderConfig { @Bean public ApplicationConfig applicationConfig(){ApplicationConfig applicationConfig = new ApplicationConfig();applicationConfig.setName('user-service-provider');applicationConfig.setOwner('lzy');applicationConfig.setOrganization('hgfzp');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> serviceConfig(UserService userService){ServiceConfig<UserService> serviceConfig = new ServiceConfig<UserService>();serviceConfig.setInterface(UserService.class);serviceConfig.setRef(userService);//配置每一個Method信息List<MethodConfig> methodConfigs = new ArrayList<>();MethodConfig methodConfig = new MethodConfig();methodConfig.setId('userService');methodConfig.setName('getUserAddressList');methodConfigs.add(methodConfig);serviceConfig.setMethods(methodConfigs);return serviceConfig; }}

ConsumerConfig.java 服務提供者使用

@Configurationpublic class ConsumerConfig { @Bean public ApplicationConfig applicationConfig(){ApplicationConfig applicationConfig = new ApplicationConfig();applicationConfig.setName('order-service-consumer');applicationConfig.setOwner('lzy');applicationConfig.setOrganization('hgfzp');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(20881);return protocolConfig; } @Bean public ServiceConfig<OrderService> serviceConfig(OrderService orderService){ServiceConfig<OrderService> serviceConfig = new ServiceConfig<OrderService>();serviceConfig.setInterface(OrderService.class);serviceConfig.setRef(orderService);//配置每一個Method信息List<MethodConfig> methodConfigs = new ArrayList<>();MethodConfig methodConfig = new MethodConfig();methodConfig.setId('orderService');methodConfig.setName('initOrder');methodConfigs.add(methodConfig);serviceConfig.setMethods(methodConfigs);return serviceConfig; }}

使用配置類需要注意兩點

需要指定dubbo配置類的包掃描路徑，啟動類上配置 @EnableDubbo(scanBasePackages = 'com.liuzeyu')

需要將接口實現暴露出來

OrderServiceImpl

UserServiceImpl

兩種方案的配置文件整合同樣可以實現RPC通信，可自行測試！
