springboot 集成dubbo

一。引入相關依賴

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。啓動導入配置

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// 導入dubbo 
        , ApplicationDruid.class// 導入Druid 
        , ApplicationMonitoring.class }) 
public class Application   { 

    @Bean 
    public WebMvcConfigurer corsConfigurer() { // 允許跨域 
        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。編寫服務端

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。消費端

   mvn clean deploy

用註釋 com.alibaba.dubbo.config.annotation.Reference; 注入

    @Reference 
    private DemoApiService demoApiService;

調用

demoApiService.queryCompany();
