本文主要介紹了IDEA整合Dubbo+Zookeeper+SpringBoot實現(xiàn)，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(wǎng)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(wǎng)查資料，發(fā)現(xiàn)針對那種入門的案例，網(wǎng)上主要有兩個比較經(jīng)典的，一個是尚硅谷雷神版，還有一個是官網(wǎng)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(xié)議和地址dubbo.registry.protocol=zookeeperdubbo.registry.address=127.0.0.1:2181#通信規(guī)則（通信協(xié)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(xiàn)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(diào)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(xié)議使用dubbo，地址和端口也必須指明，否則會發(fā)現(xiàn)UserService 注入為null的現(xiàn)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(diào)式

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

實現(xiàn)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(xié)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(xié)議實現(xiàn)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(xiàn)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(xié)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(xié)議實現(xiàn)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(xiàn)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(xiàn)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(xiàn)暴露出來

OrderServiceImpl

UserServiceImpl

兩種方案的配置文件整合同樣可以實現(xiàn)RPC通信，可自行測試！
