Http服務(wù)與Dubbo服務(wù)相互轉(zhuǎn)換的SpringBoot代理節(jié)點(diǎn)實(shí)現(xiàn)方式

更新時(shí)間：2025年10月23日 08:41:50 作者：遲到的月亮

文章主要討論如何在項(xiàng)目中增加一個(gè)SpringBoot節(jié)點(diǎn),作為HTTP與Dubbo服務(wù)之間的代理節(jié)點(diǎn),該節(jié)點(diǎn)通過注冊(cè)到Eureka,提供SpringCloud服務(wù),并支持Dubbo代理Bean的管理,文章提到使用io.dubbo:spring-boot-starter-dubbo依賴,但遇到消費(fèi)者配置生產(chǎn)者的問題

1.需求

目前有些項(xiàng)目已經(jīng)接入了Spring cloud管理，節(jié)點(diǎn)間通信（包括老項(xiàng)目）通過eureka（非boot web項(xiàng)目的注eureka注冊(cè)與發(fā)現(xiàn)參照前文）提供http通信，由于我們公司內(nèi)部項(xiàng)目間交流要求通過dubbo做服務(wù)的暴露與消費(fèi)，考慮新加一個(gè)boot節(jié)點(diǎn)用于http與dubbo之間的相互轉(zhuǎn)換

2.主要思想，方案與問題

主要思想

<1>做一個(gè)Spring Boot節(jié)點(diǎn)用于http與dubbo服務(wù)的代理

<2>Http調(diào)用Dubbo：

將節(jié)點(diǎn)接入Spring Cloud管理，注冊(cè)到eureka上提供SC方面的服務(wù)，節(jié)點(diǎn)依賴需要接入的項(xiàng)目jar包，并配置掃描等將Dubbo代理Bean交由Spring Bean管理，通過通用的Controller提供http服務(wù)（通用controller后面會(huì)說）

<3>Dubbo調(diào)用Http：

這個(gè)相對(duì)簡(jiǎn)單，只需要對(duì)dubbo暴露一個(gè)通用接口，調(diào)用方在調(diào)用的時(shí)候指定要調(diào)用的鏈接，入?yún)⒌葏?shù)，做一層轉(zhuǎn)發(fā)就可以

方案與問題

<1> 依賴io.dubbo.springboot:spring-boot-starter-dubbo:1.0.0這個(gè)jar中提供了很多接入SC的配置，但在開發(fā)完成后發(fā)現(xiàn)一個(gè)致命問題，就是好像不支持一個(gè)消費(fèi)者配置多個(gè)生產(chǎn)者，查看源碼也沒有找到很好的解決方案（個(gè)人水平有限）…此方案相對(duì)簡(jiǎn)單，如果只針對(duì)一個(gè)生產(chǎn)者，可以考慮此方案

<2> 消費(fèi)者配置生產(chǎn)者仍然采用原先的xml配置，項(xiàng)目依賴也只是原始的dubbo依賴，其余手動(dòng)配置(通過@Value從配置中心拿)

3.核心代碼

扯了那么多沒用的，終于輪到代碼了(這里只公開了核心代碼)…

啟動(dòng)類:HttpDubboProxyApplication:

/**
 * Created by Kowalski on 2017/7/11
 * Updated by Kowalski on 2017/7/11
 */
@SpringBootApplication
@EnableEurekaClient
@ImportResource("classpath:dubbo-consumer.xml")
public class HttpDubboProxyApplication {
    public static void main(String... args) {
        // 程序啟動(dòng)入口
        SpringApplication.run(HttpDubboProxyApplication.class,args);
    }
}

項(xiàng)目啟動(dòng)時(shí)一些基本配置Bean（類xml）ConfigurationBean:

/**
 * Created by Kowalski on 2017/7/17
 * Updated by Kowalski on 2017/7/17
 * 配置bean
 */
@Configuration
public class ConfigurationBean {

    @Bean
    ProxySpringContextsUtil proxySpringContextsUtil(){
        return new ProxySpringContextsUtil();
    }

    @Bean
    AnnotationBean annotationBean(){
        AnnotationBean annotationBean = new AnnotationBean();
        /**啟動(dòng)掃描包（與正常dubbo掃描類似）*/
        annotationBean.setPackage("com.kowalski.proxy.service");
        return annotationBean;
    }

    @Bean
    public RestTemplate restTemplate() {
        RestTemplate restTemplate = new RestTemplate();
        /**設(shè)置傳輸格式 避免中文亂碼*/
        restTemplate.getMessageConverters().set(1, new StringHttpMessageConverter(StandardCharsets.UTF_8));
        return restTemplate;
    }
}

我們這里http請(qǐng)求通過restTemplate，也可以使用feign

上段代碼的proxySpringContextsUtil：

package com.kowalski.proxy;

import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

    private static ApplicationContext applicationContext;    //Spring應(yīng)用上下文環(huán)境

    /**

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) {
        ProxySpringContextsUtil.applicationContext = applicationContext;
    }

    /**

        return applicationContext;

     */
    public static Object getBean(String name) {
        return applicationContext.getBean(name);
    }


    /**

     * @param requiredType 返回對(duì)象類型

     */
    public static Object getBean(String name, Class<?> requiredType) {
        return applicationContext.getBean(name, requiredType);
    }

    /**
     * 如果BeanFactory包含一個(gè)與所給名稱匹配的bean定義，則返回true
     * @param name
     * @return boolean
     */
    public static boolean containsBean(String name) {
        return applicationContext.containsBean(name);
    }

    /**

     * 如果與給定名字相應(yīng)的bean定義沒有被找到，將會(huì)拋出一個(gè)異常（NoSuchBeanDefinitionException）
     * @param name
     * @return boolean
     * @throws NoSuchBeanDefinitionException
     */
    public static boolean isSingleton(String name) {
        return applicationContext.isSingleton(name);
    }

    /**
     * @param name
     * @return Class 注冊(cè)對(duì)象的類型
     * @throws NoSuchBeanDefinitionException
     */
    public static Class<?> getType(String name) {
        return applicationContext.getType(name);
    }

    /**
     * 如果給定的bean名字在bean定義中有別名，則返回這些別名
     * @param name
     * @return
     * @throws NoSuchBeanDefinitionException
     */
    public static String[] getAliases(String name) {
        return applicationContext.getAliases(name);
    }
}

此工具類主要用于獲取Spring管理的Bean

由于已經(jīng)將dubbo的代理Bean交由Spring Bean管理，因此通過ProxySpringContextsUtil 拿到代理，通過方法名拿到方法，通過方法拿到入?yún)㈩愋?，再將入?yún)⑥D(zhuǎn)化成對(duì)應(yīng)類型的參數(shù)invoke(之前有考慮過不管參數(shù)類型直接交給dubbo代理類去invoke，但好像必須要制定類型的入?yún)?，不然?bào)錯(cuò))
