Spring boot整合dubbo+zookeeper
下文将简述springboot整合dubbo+zookeeper实现api+provider+consumer模式，Api用于定于interface,provider和consumer依赖Api,provider实现api接口，consumer调用provider。
spring boot版本：3.5.3
jdk版本：Java17
1.创建父工程
此处只勾选了spring web和lombok，需要Orm框架自行增加
2.父工程引入依赖
父工程pom.XML，引入dubbo和zookeeper相关依赖，修改packaging为pom不打包，并删除src目录
<dependency>
<groupId>org.apache.dubbo</groupId>
<artifactId>dubbo-spring-boot-starter</artifactId>
<version>3.2.10</version>
</dependency>
<!-- Zookeeper客户端 -->
<dependency>
<groupId>org.apache.curator</groupId>
<artifactId>curator-recipes</artifactId>
<version>5.2.0</version>
</dependency>
<dependency>
<groupId>org.apache.curator</groupId>
<artifactId>curator-framework</artifactId>
<version>5.2.0</version>
</dependency>
<dependency>
<groupId>org.apache.curator</groupId>
<artifactId>curator-x-discovery</artifactId>
<version>5.2.0</version> <!-- 与Zookeeper版本匹配 -->
</dependency>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>3.5.3</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>3.创建api子模块
（1）.新建dubbo-api module
（2）.修改pom.xml文件
修改dubbo-api的pom.xml,parent修改为刚才新建的groupId、artifactId和version，再去掉重复的配置
<parent> <groupId>com.example</groupId> <artifactId>DubboDemo</artifactId> <version>0.0.1-SNAPSHOT</version> </parent>
父工程pom.xml增加子模块
<modules>编程; <module>dubbo-api</module> </modules>
（China编程 3）.修改配置
修改application.properties为application.yml，并增加dubbo配置内容
spring:
application:
name: dubbo-api
config:
activate:
on-profile: default
server:
port: 8080
dubbo:
application:
name: dubbo-api
protocol:
name: dubbo
port: 20880
registry:
address: zookeeper://192.168.48.154:2181dubbo.protocol 此处协议不是自定义的，自由dubbo、rpc等类型
registry：配置zookeeper地址
(4)启动类，开启dubbo，
@EnableDubbo 注解用于开启dubbo客户端，scanBasePackages 可以配置包路径
@SpringBootApplication
@EnableDubbo
public class DubboApiApplication{
public static void main(String[] args) {
SpringApplication.run(DubboProviderApplication.class, args);
}
}（5）新增Service接口
public interface TestService {
String sayHello(String name);
}4.创建provider子模块
（1）创建dubbo-provider模块，和上面一样，就不赘述了
（2）修改pom.xml文件
依赖中加入api模块的依赖
<dependencies>
<dependency>
<groupId>com.example</groupId>
<artifactId>dubbo-api</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>（3）修改配置文件
application.yml
spring:
application:
name: provider
config:
activate:
on-profile: default
server:
port: 8081
dubbo:
application:
name: dubbo-provider
qos-enable: true
qos-port: 22223
registry:
address: zookeeper://192.168.48.154:2181
protocol:
name: dubbo
port: 20881 #同一台机器不能相同对比api模块增加了qos-enable和qos-port两个属性，QoS是Dubbo提供的运维和管理功能，表示开启；qos-port表示运维管理功能的端口
(4)启动类，开启dubbo，
@EnableDubbo 注解用于开启dubbo客户端，scanBasePackages 可以配置包路径
@SpringBootApplication
@EnableDubbo
public class DubboProviderApplication {
public static void main(String[] args) {
System.setProperty("zookeeper.sasl.client", "false");
SpringApplication.run(DubboProviderApplication.class, args);
}
}（5）实现TestService接口
package com.examplexu.dubboprovider.service;
import com.examplexu.duubo.service.TestService;
import org.apache.dubbo.config.annotation.DubboService;
@DubboService(version = "1.0.0")
public class TestServiceImpl implements TestService {
@Override
public String sayHello(String name) {
return "welcome"+name+" to dubbo!";
}
}@DubboService 的作用为标记TestService为服务提供者，暴露为dubbo服务，并注册到zookeeper并进行管理。可以配置的参数如下：
version: 服务版本号(必填)
timeout: 调用超时时间(毫秒)
loadbalance: 负载均衡策略
retries: 失败重试次数
check: 启动时检查依赖服务是否可用
5.创建consumer子模块
（1）创建dubbo-consumer模块，和上面一样，就不赘述了
（2）修改pom.xml文件
依赖中加入api模块的依赖
<dependencies>
<dependency>
<groupId>com.example</groupId>
<artifactId>dubbo-api</artifactId>
编程 <version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>(3)修改配置文件
spring:
application:
name: consumer
config:
activate:
on-profile: default
server:
port: 8084
dubbo:
config:
application:
name: dubbo-consumer
qos-enable: true
qos-port: 22224
registry:
address: zookeeper://192.168.48.154:2181
timeout: 20000
protocol:
name: dubbo
port: 20882
config-center:
timeout: 20000此处增加了超时时间,注册中心如果超时，会抛出异常，若配置了重试会进行重试操作；配置中心超时，会记录警告日志，可能会影响动态配置更新
(5)启动类，开启dubbo
@SpringBootApplication
@EnableDubbo
public class DubboConsumerApplication {
public static void main(String[] args) {
System.setProperty("zookeeper.sasl.client", "false");
SpringApplication.run(DubboConsumerApplication.class, args);
}
}（6)增加Controller调用provider
@RestController
@RequestMapping("/consumer")
public class TestController {
@DubboReference(version = "1.0.0",timeout = 5000,loadbalance = "roundrobin",retries = 3,check = false)
private TestService testService;
@GetMapping("/sayHello")
public String test(String name) {
return testService.sayHello(name);
}
}@DubboReference 用于标记引用Dubbo服务，自动从注册中心发现并创建服务代理，实现服务的远程调用。主要配置参数如下：
version 版本号，与服务提供者提供的version一直
timeout 单次调用超时时间
loadbalance 负载均衡策略有random/roundrobin/leastactive策略，即随机、轮询、近期最少使用
retries 失败自动重试次数
check 启动时是否检查依赖服务的可用性
6.启动服务
依次启动dubbo-api、dubbo-provider、dubbo-consumer;启动时可以查看日志会出现很多zookeeper和dubbo的日志
启动过程中如果报错：
2025-07-10T15:28:14.979+08:00 ERROR 37840 --- [consumer] [ main] o.a.d.c.deploy.DefaultModuleDeployer : [DUBBO] Model reference failed: Dubbo Module[1.1.1] , catch error : Can not create registry service-discovery-registry://192.168.48.154:2181/org.apache.dubbo.registry.RegistryService?application=dubbo-consumer&dubbo=2.0.2&executor-management-mode=isolation&file-cache=true&interface=org.apache.dubbo.registry.RegistryService&pid=37840&qos.enable=true&qos.编程China编程port=22224®istry=zookeeper&release=3.2.10&timeout=20000, dubbo version: 3.2.10, current host: 192.168.1.93, error code: 5-15.

启动类中新增：
System.setProperty("zookeeper.sasl.client", "false");表示不进行SASL认证，生产环境视要求具体设置
测试结果
当dubbo-api、dubbo-provider和dubbo-consumer都启动完成后，使用消费者接口访问。
可以发现此处消费者调用的是提供者的实现内容。
