spring boot+dubbo

        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

dubbo.application.name=application_dubbo.application.logger=slf4jdubbo.annotation.package=hello.dubbodubbo.protocol.name=dubbodubbo.protocol.port=20880dubbo.protocol.accessLog=truedubbo.provider.timeout=3000dubbo.provider.retries=1dubbo.provider.delay=-1dubbo.registr.protocol=zookeeperdubbo.registry.address=127.0.0.1:2181dubbo.registry.register=truedubbo.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;@SpringBootApplicationpublic 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。
