使用springboot搭建dubbo服务，首先封装出springboot-dubbo的项目，引入在服务上加直接@Service直接使用，方便于拆封统一管理。

package hello.dubbo.configuration;import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;import com.alibaba.dubbo.config.ApplicationConfig;
import com.alibaba.dubbo.config.ProtocolConfig;
import com.alibaba.dubbo.config.ProviderConfig;
import com.alibaba.dubbo.config.RegistryConfig;
import com.alibaba.dubbo.config.spring.AnnotationBean;
import com.alibaba.dubbo.rpc.Exporter;@Configuration
@ConditionalOnClass(Exporter.class)
@PropertySource(value = "classpath:/dubbo.properties")
public class DubboConfiguration { @Value("${dubbo.application.name}")
private String applicationName; @Value("${spring.redis.host}")
private String logger; @Value("${dubbo.registr.protocol}")
private String protocol; @Value("${dubbo.registry.address}")
private String registryAddress; @Value("${dubbo.protocol.name}")
private String protocolName; @Value("${dubbo.protocol.port}")
private int protocolPort; @Value("${dubbo.provider.timeout}")
private int timeout; @Value("${dubbo.provider.retries}")
private int retries; @Value("${dubbo.provider.delay}")
private int delay; /**
* 设置dubbo扫描包
* @param packageName
* @return
*/
@Bean
public static AnnotationBean annotationBean(@Value("${dubbo.annotation.package}") String packageName) {
AnnotationBean annotationBean = new AnnotationBean();
annotationBean.setPackage(packageName);
return annotationBean;
} /**
* 注入dubbo上下文
*
* @return
*/
@Bean
public ApplicationConfig applicationConfig() {
// 当前应用配置
ApplicationConfig applicationConfig = new ApplicationConfig();
applicationConfig.setName(this.applicationName);
return applicationConfig;
} /**
* 注入dubbo注册中心配置,基于zookeeper
*
* @return
*/
@Bean
public RegistryConfig registryConfig() {
// 连接注册中心配置
RegistryConfig registry = new RegistryConfig();
registry.setProtocol(protocol);
registry.setAddress(registryAddress);
return registry;
} /**
* 默认基于dubbo协议提供服务
*
* @return
*/
@Bean
public ProtocolConfig protocolConfig() {
// 服务提供者协议配置
ProtocolConfig protocolConfig = new ProtocolConfig();
protocolConfig.setName(protocolName);
protocolConfig.setPort(protocolPort);
protocolConfig.setThreads(200);
System.out.println("默认protocolConfig：" + protocolConfig.hashCode());
return protocolConfig;
} /**
* dubbo服务提供
*
* @param applicationConfig
* @param registryConfig
* @param protocolConfig
* @return
*/
@Bean(name="defaultProvider")
public ProviderConfig providerConfig(ApplicationConfig applicationConfig, RegistryConfig registryConfig, ProtocolConfig protocolConfig) {
ProviderConfig providerConfig = new ProviderConfig();
providerConfig.setTimeout(timeout);
providerConfig.setRetries(retries);
providerConfig.setDelay(delay);
providerConfig.setApplication(applicationConfig);
providerConfig.setRegistry(registryConfig);
providerConfig.setProtocol(protocolConfig);
return providerConfig;
} public String getApplicationName() {
return applicationName;
} public void setApplicationName(String applicationName) {
this.applicationName = applicationName;
} public String getLogger() {
return logger;
} public void setLogger(String logger) {
this.logger = logger;
} public String getProtocol() {
return protocol;
} public void setProtocol(String protocol) {
this.protocol = protocol;
} public String getRegistryAddress() {
return registryAddress;
} public void setRegistryAddress(String registryAddress) {
this.registryAddress = registryAddress;
} public String getProtocolName() {
return protocolName;
} public void setProtocolName(String protocolName) {
this.protocolName = protocolName;
} public int getProtocolPort() {
return protocolPort;
} public void setProtocolPort(int protocolPort) {
this.protocolPort = protocolPort;
} public int getTimeout() {
return timeout;
} public void setTimeout(int timeout) {
this.timeout = timeout;
} public int getRetries() {
return retries;
} public void setRetries(int retries) {
this.retries = retries;
} public int getDelay() {
return delay;
} public void setDelay(int delay) {
this.delay = delay;
}}

代码启动读取dubbo.properties资源文件，也可以把配置信息存在application.properties。

基础dubbo服务项目配置成功！

dubbo服务项目依赖基础dubbo服务项目，即可使用dubbo服务

dubbo.properties文件

dubbo.application.name=application_
dubbo.application.logger=slf4jdubbo.annotation.package=hello.dubbodubbo.protocol.name=dubbo
dubbo.protocol.port=20880
dubbo.protocol.accessLog=truedubbo.provider.timeout=3000dubbo.provider.retries=1
dubbo.provider.delay=-1dubbo.registr.protocol=zookeeperdubbo.registry.address=127.0.0.1:2181
dubbo.registry.register=true
dubbo.registry.subscribe=true

服务提供类

package hello.dubbo;import com.alibaba.dubbo.config.annotation.Service;
import com.jon.show.service.IDubboDemoService;@Service(version="1.0.0")
public class DubboDemoServiceImpl implements IDubboDemoService{ @Override
public String sayHello(String name) {
return "hello " + name;
} @Override
public String sayYourAge(int age) {
return null;
}}

application启动类

package hello;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.orm.jpa.vendor.HibernateJpaSessionFactoryBean;@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
} /**
* 注入sessionfatory
* @return
*/
@Bean
public HibernateJpaSessionFactoryBean sessionFactory() {
return new HibernateJpaSessionFactoryBean();
}
}

dubbo服务配置成功！即可使用。
