Dubbo--集成SpringBoot

创建Maven 工程 (dubbo_test)

引入依赖：

	<dependencies>
        <!-- dubbo -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>
            <version>2.6.2</version>
        </dependency>
        <!-- 客户端 -->
        <dependency>
            <groupId>org.apache.curator</groupId>
            <artifactId>curator-framework</artifactId>
            <version>2.12.0</version>
        </dependency>
    </dependencies>

创建子模块：（myinterface）

实体类：UserAddress

public class UserAddress implements Serializable {
	
	private Integer id;
    private String userAddress; //用户地址
    private String userId; //用户id
    private String consignee; //收货人
    private String phoneNum; //电话号码
    private String isDefault; //是否为默认地址    Y-是     N-否
    
    public UserAddress() {
		super();
		// TODO Auto-generated constructor stub
	}
    
	public UserAddress(Integer id, String userAddress, String userId, String consignee, String phoneNum,
			String isDefault) {
		super();
		this.id = id;
		this.userAddress = userAddress;
		this.userId = userId;
		this.consignee = consignee;
		this.phoneNum = phoneNum;
		this.isDefault = 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;
	}


	@Override
	public String toString() {
		return "UserAddress{" +
				"id=" + id +
				", userAddress='" + userAddress + '\'' +
				", userId='" + userId + '\'' +
				", consignee='" + consignee + '\'' +
				", phoneNum='" + phoneNum + '\'' +
				", isDefault='" + isDefault + '\'' +
				'}';
	}
}

UserService

/**
 * 用户服务
 * @author lfy
 *
 */
public interface UserService {
	
	/**
	 * 按照用户id返回所有的收货地址
	 * @param userId
	 * @return
	 */
	public List<UserAddress> getUserAddressList(String userId);

}

OrderService

public interface OrderService {
	
	/**
	 * 初始化订单
	 * @param userId
	 */
	public List<UserAddress> initOrder(String userId);

}

创建用户子模块：(user-service)

引入依赖：

实现UserService：

@com.alibaba.dubbo.config.annotation.Service //暴露服务
@Component
public class UserServiceImpl implements UserService {

    public List<UserAddress> getUserAddressList(String userId) {
        UserAddress address1 = new UserAddress(1, "北京市昌平区宏福科技园综合楼3层","1","李老师","101-56253825", "Y");
        UserAddress address2 = new UserAddress(2, "深圳市宝安区西部硅谷大厦B座3层","1","王老师", "010-562531", "N");
        return Arrays.asList(address1, address2);
    }
}

配置Dubbo（application.properties）

dubbo.application.name=user-service
dubbo.registry.address=127.0.0.1:2181
dubbo.registry.protocol=zookeeper
dubbo.protocol.name=dubbo
dubbo.protocol.port=20880

spring.http.encoding.force=true
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
server.tomcat.uri-encoding=UTF-8

启动类：

@EnableDubbo //开启基于注解的dubbo配置
@SpringBootApplication
public class UserServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(UserServiceApplication.class, args);
    }

}

创建Order子模块：(order-service)

实现OrderService：

@Service
public class OrderServiceImpl implements OrderService {

    @Reference //Bubbo提供，自动发现已注册的服务，远程引用
    UserService userService;

    public List<UserAddress> initOrder(String userId) {
        System.out.println(userId);
        //调用UserService查询用户收货地址
        List<UserAddress> userAddressList = userService.getUserAddressList(userId);
        return userAddressList;
    }
}

Controller：

@Controller
public class OrderController {

    @Autowired
    OrderService orderService;

    @ResponseBody
    @RequestMapping("/initOrder")
    public List<UserAddress> initOrder(@RequestParam("uid") String userId){
        return orderService.initOrder(userId);
    }
}

配置Dubbo（application.properties）

server.port=8081

dubbo.application.name=order-service
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.monitor.protocol=registry


spring.http.encoding.force=true
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
server.tomcat.uri-encoding=UTF-8

启动类：

@EnableDubbo
@SpringBootApplication
public class OrderServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(OrderServiceApplication.class, args);
    }

}

测试

启动zookeepter

启动user模块，启动order模块。

访问localhost:8081/initOrder?uid=1
