spring/springboot整合dubbo详细教程
一、基本使用
需求:
某个电商系统,订单服务需要调用用户服务获取某个用户的所有地址;
我们现在需要创建两个服务模块进行测试
模块
功能
订单服务web模块
创建订单等
用户服务service模块
查询用户地址等
测试预期结果:
订单服务web模块在A服务器,用户服务模块在B服务器,A可以远程调用B的功能。
二、spring整合dubbo
以下使用XML 配置的方式,更多配置方式见官方文档
2.1 spring-common模块:
公共接口层(model,service,exception…),定义公共接口,也可以导入公共依赖
UserAddress.java:用户地址实体类
public class UserAddress implements Serializable {
private Integer id;
private String userAddress;
private String userId;
private String consignee;
private String phoneNum;
private String isDefault;
....
}
IOrderService.java:订单接口
public interface IOrderService {
/**
* 用户下单
* @param userId
*/
UserAddress placeOrder(int userId);
}
IUserService.java:用户接口
public interface IUserService {
/**
* 根据用户id获取用户地址
* @param userId
* @return
*/
http:// UserAddress getUserAddById(int userId);
}
pom.xml:通用的依赖,引入dubbo和zkclient
xmlns:xsi="http://w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
xmlns:xsi="http://w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
2.2 spring-user模块:
用户业务,作为服务提供者
pom.xml:引入通用模块,可以使用定义的接口
UserServiceImpl.xml:IUserService的实现类,供远程调用
public class UserServiceImpl implements IUserService {
@Override
public UserAddress getUserAddById(int userId) {
UserAddress userAddress = new UserAddress();
userAddress.setUserAddress("上海市宝山区");
return userAddress;
}
}
provider.xml:dubbo配置信息
xmlns:xsi="http://w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans.xsd http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
xmlns:xsi="http://w3.org/2001/XMLSchema-instance"
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans.xsd
http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd
http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
ConsumerRun.java:启动:
public class ConsumerRun {
public static void main(String[] args) throws IOException {
ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("consumer.xml");
IOrderService orderService = applicationContext.getBean(IOrderService.class);
orderService.placeOrder(1);
System.in.read();
}
}
2.3 spring-order模块:
订单业务,作为服务消费者
pom.xml:引入通用模块,可以使用定义的接口,同1.2
OrderServiceImpl.xml:IOrderService的实现类,其中远程调用userService
@Service
public class OrderServiceImpl implements IOrderService {
@Autowired
private IUserService userService;
@Override
public UserAddress placeOrder(int userId) {
// 远程调用,获取用户地址
UserAddress userAddById = userService.getUserAddById(userId);
// 下单
System.out.println("用户地址:" + userAddById.getUserAddress());
Systemhttp://.out.println("下单成功");
return null;
}
}
consumer.xml:dubbo配置信息
xmlns:xsi="http://w3.org/2001/XMLSchema-instance" xmlns:context="http://springframework.org/schema/context" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans.xsd http://springframework.org/schema/context http://springframework.org/schema/context/spring-context-4.3.xsd http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
xmlns:xsi="http://w3.org/2001/XMLSchema-instance"
xmlns:context="http://springframework.org/schema/context"
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans.xsd
http://springframework.org/schema/context http://springframework.org/schema/context/spring-context-4.3.xsd
http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd
http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
ProviderRun.java:启动
public class ProviderRun {
public static void main(String[] args) throws IOException {
ClassPathXmlApplicationContext context =
new ClassPathXmlApplicationContext("classpath:provider.xml");
System.in.read();
}
}
2.4 效果
ProviderRun启动之后阻塞,
ConsumerRun启动之后调用orderService.placeOrder(1),placeOrder中远程调用spring-user模块中的userService.getUserAddById(userId)获取用户地址:
用户地址:上海市宝山区
下单成功
三、springboot整合dubbo
3.1 boot-common模块:
公共接口层(model,service,exception…),定义公共接口,也可以导入公共依赖
UserAddress.java:用户地址实体类
public class UserAddress implements Serializable {
private Integer id;
private String userAddress;
private String userId;
private String consignee;
private String phoneNum;
private String isDefault;
....
}
IOrderService.java:订单接口
public intehttp://rface IOrderService {
/**
* 用户下单
* @param userId
*/
UserAddress placeOrder(int userId);
}
IUserService.java:用户接口
public interface IUserService {
/**
* 根据用户id获取用户地址
* @param userId
* @return
*/
UserAddress getUserAddById(int userId);
}
pom.xml:通用的依赖,引入dubbo的starter
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
3.2 boot-user模块:
用户业务,作为服务提供者
pom.xml:引入通用模块,可以使用定义的接口
UserServiceImpl.xml:IUserService的实现类,供远程调用
@Service 暴露dubbo的服务
@Service
@Component
public class UserServiceImpl implements IUserService {
@Override
public UserAddress getUserAddById(int userId) {
UserAddress userAddress = new UserAddress();
userAddress.setUserAddress("上海市宝山区");
return userAddress;
}
}
application.properties:dubbo配置信息
dubbo.application.name=boot-user
dubbo.registry.address=192.168.31.136:2181
dubbo.registry.protocol=zookeeper
dubbo.protocol.name=dubbo
dubbo.protocol.port=20880
BootUserApplication.java:启动:
@EnableDubbo : 开启基于注解的dubbo功能
@EnableDubbo
@SpringBootApplication
public class BootUserApplication {
public static void main(String[] args) {
SpringApplication.run(BootUserApplication.class, args);
}
}
3.3 boot-order模块:
订单业务,作为服务消费者
pom.xml:引入通用模块,可以使用定义的接口,同1.2
OrderServiceImpl.xml:IOrderService的实现类,其中远程调用userService
@Reference:引用远程提供者服务
@Service
public class OrderServiceImpl implements IOrderService {
//引用远程提供者服务
@Reference
private IUserService userService;
@Override
public UserAddress placeOrder(int userId) {
// 远程调用,获取用户地址
UserAddress userAddById = userService.getUserAddById(userId);
return userAddById;
}
}
OrderController.java:web接口,调用OrderService:
@Controller
public class OrderController {
@Autowired
IOrderService orderService;
@RequestMapping("/initOrder")
@ResponseBody
public UserAddress initOrder(@RequestParam("uid")int userId) {
return orderService.placeOrder(userId);
}
}
application.properties:dubbo配置信息
server.port=8081
dubbo.application.name=boot-order
dubbo.registry.address=zookeeper://192.168.31.136:2181
BootOrderApplication.java:启动
@EnableDubbo
@SpringBootApplication
public class BootOrderApplication {
public static void main(String[] args) {
SpringApplication.run(BootOrderApplication.class, args);
}
}
