springboot 集成dubbo

一。引入相关依赖

pom.xml

        <!-- dubbo -->         <dependency>             <groupId>com.alibaba</groupId>             <artifactId>dubbo</artifactId>             <version>2.8.4</version>         </dependency>         <dependency>             <groupId>org.apache.zookeeper</groupId>             <artifactId>zookeeper</artifactId>             <version>3.4.8</version>         </dependency>         <dependency>             <groupId>com.github.sgroschupf</groupId>             <artifactId>zkclient</artifactId>             <version>0.1</version>         </dependency>

​

二。引入配置

package com.jztey.framework.boot; import com.alibaba.dubbo.config.*; import com.alibaba.dubbo.config.spring.AnnotationBean; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.Bean; /**  * Created by Charles on 2016/6/11.  */ public class ApplicationDubbo {     @Bean     @ConfigurationProperties(prefix = "dubbo.application")     public ApplicationConfig applicationConfig() {         return new ApplicationConfig();     }     @Bean     @ConfigurationProperties(prefix = "dubbo.protocol")     public ProtocolConfig protocolConfig() {         return new ProtocolConfig();     }     @Bean     @ConfigurationProperties(prefix = "dubbo.registry")     public RegistryConfig registryConfig() {         return new RegistryConfig();     }     @Bean     @ConfigurationProperties(prefix = "dubbo.annotation")     public AnnotationBean annotationBean() {         return new AnnotationBean();     }     @Bean     @ConfigurationProperties(prefix = "dubbo.provider")     public ProviderConfig providerConfig() {         return new ProviderConfig();     }     @Bean     @ConfigurationProperties(prefix = "dubbo.reference")     public ReferenceConfig referenceConfig() {         return new ReferenceConfig();     }     @Bean     @ConfigurationProperties(prefix = "dubbo.consumer")     public ConsumerConfig consumerConfig() {         return new ConsumerConfig();     } }

​

三。启动导入配置

package com.jztey.gxdemo; import java.net.UnknownHostException; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cache.annotation.CachingConfigurer; import org.springframework.cache.annotation.EnableCaching; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Import; import org.springframework.data.redis.connection.RedisConnectionFactory; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer; import org.springframework.data.redis.serializer.StringRedisSerializer; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.servlet.config.annotation.CorsRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; import com.alibaba.fastjson.JSONObject; import com.fasterxml.jackson.annotation.JsonAutoDetect; import com.fasterxml.jackson.annotation.PropertyAccessor; import com.fasterxml.jackson.databind.ObjectMapper; import com.jztey.framework.boot.ApplicationDruid; import com.jztey.framework.boot.ApplicationDubbo; import com.jztey.framework.boot.ApplicationInterfaceMvc; import com.jztey.framework.boot.ApplicationMonitoring; import com.jztey.gxdemo.entity.OauthParam; import com.jztey.gxdemo.service.DemoApiService; /**  * Created by yushi on 2016/8/8.  */ @SpringBootApplication @Import({ ApplicationInterfaceMvc.class //         , ApplicationDubbo.class// 导入dubbo         , ApplicationDruid.class// 导入Druid         , ApplicationMonitoring.class }) public class Application   {     @Bean     public WebMvcConfigurer corsConfigurer() { // 允许跨域         return new WebMvcConfigurerAdapter() {             @Override             public void addCorsMappings(CorsRegistry registry) {                 registry.addMapping("/**").allowedOrigins("*").allowedMethods("GET", "POST", "DELETE", "PUT",                         "OPTIONS");             }         };     }     public static void main(String[] args) {         SpringApplication.run(Application.class, args);     } }

​

四。application.properties配置

#dubbo配置 dubbo.application.name=gxdemo dubbo.registry.protocol=zookeeper dubbo.registry.address=10.3.5.36:2181,10.3.5.38:2181,10.3.5.42:2181 dubbo.annotation.package=com.jztey.${spring.application.name}

​

五。编写服务端

package com.jztey.gxdemo.service; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import org.springframework.web.client.RestOperations; import com.alibaba.fastjson.JSONArray; import com.jztey.gxdemo.entity.OauthParam; @com.alibaba.dubbo.config.annotation.Service @Service public class DemoApiServiceImpl implements DemoApiService{     @Autowired     private RestOperations restOperations;     @Autowired     private OauthService oauthService;     public JSONArray queryCompany(){         String url = "https://internal.api.ehaoyao.com/logistics/v1.1/company";             OauthParam param = new OauthParam();         param.setGrantType("client_credentials");         param.setClientId("02bceec105cd4462b2dadd892fdba943");         param.setClientSecret("fa50ffdbbbf9442f8958e1493e7a1b41");         param.setScope("mall");         String token = oauthService.getToken(param);         url=url+"?access_token="+token;         JSONArray result =  restOperations.getForObject(url, JSONArray.class);         System.out.println(result.toString());         return result;   }     }

​

六。消费端

   mvn clean deploy

用注释 com.alibaba.dubbo.config.annotation.Reference; 注入

    @Reference     private DemoApiService demoApiService;

调用

demoApiService.queryCompany();
