文章标签 dubbo 模块化应用通信 spring 文章分类 架构后端开发

背景：
传统的项目是单一的，当业务不断增长，系统的功能不断增加，系统就会边的臃肿庞大难以维护，最常见的就是，修改一个小功能，整个系统得重新部署启动，对于频繁的迭代，令人抓狂。近几年，模块化的思想兴起，将庞大的系统拆分成多个功能模块，这样很大程度上解决的以上的烦恼。旧的的问题解决，但又带来新的问题，模块之间的服务调用通信怎么解决？rpc解决了这个问题，dubbo就是rpc的典型代表。

使用（基于sprng框架系列）：
1.使用主流的开发框架springmvc与dubbo整合，maven管理依赖包。
2.项目结构如图：

使用maven的继承和聚合功能来管理项目的。

3.上篇文章提到，dubbo是分为消费方和生产方的，这里phoenix-organ-web 代表消费方（多个）；phoenix-organ-provider代表生产方；phoenix-organ-api则是一个接口，里面包含生产方需要实现，消费方需要调用的接口和实体类，准确的说 api是需要打包发布私服的，然后消费方和生产方都需要通过坐标引用该jar包的，双方的引用api的目的不同，生产方需要具体实现这些接口的功能，消费方式主要是通过来找到需要调用的方法而已。

4.这三个子项目中除了基本的spring配置文件，还有重要的几个配置文件，这才是关键。
phoenix-organ-api：organ-dubbo-consumer.xml 内容如下：

organ-dubbo-config.xml ,代码如下：

    <dubbo:registry address="${dubbo.registry.address}" protocol="${dubbo.protocol.name}"/>
    <dubbo:consumer timeout="10000" check="false" />
</beans>

applicationContext.xml 中代码添加如下：

<import resource="classpath:organ-dubbo-config.xml" />
<import resource="classpath:organ-dubbo-provider.xml" />

phoenix-organ-web：organ-dubbo-config.xml 代码如下

<?xml version="1.0" encoding="UTF-8"?>

    <dubbo:registry address="${dubbo.registry.address}" protocol="${dubbo.protocol.name}"/>
    <dubbo:consumer timeout="10000" check="false" />
</beans>

applicationContext.xml 中代码添加如下：

<import resource="classpath:organ-dubbo-config.xml" />
<import resource="classpath:organ-dubbo-consumer.xml" />

5.启动dubbo。启动dubbo的时候，需要在phoenix-organ-provider 中启动，需要做一些启动配置，还有打包插件。
首先在 pom.xml 里添加插件插件配置：

<plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
            <descriptor>src/main/assembly/assembly.xml</descriptor>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
    </plugin>

</assembly>

插件配置好以后，再配置dubbo的文件，dubbo.properties 和 log4j.xml
dubbo.properties 代码：

dubbo.spring.config=classpath:applicationContext.xml
dubbo.log4j.config=classpath:log4j.xml

organ.jdbc.driverClassName=com.mysql.jdbc.Driver
organ.jdbc.url=${jdbc.url}
organ.jdbc.username=${jdbc.username}
organ.jdbc.password=${jdbc.password}

cache.expiredTime=86400

organ.redis.host=${redis.host}
organ.redis.port=${redis.port}
organ.mongodb.address=${mongodb.address}
organ.mongodb.database=${mongodb.database}

organ.dubbo.application.name=${dubbo.application.name}
organ.dubbo.registry.address=${dubbo.registry.address}
organ.dubbo.protocol.name=${dubbo.protocol.name}
organ.dubbo.protocol.port=${dubbo.protocol.port}
organ.bigdata.host=${organ.bigdata.host}
log4j.path=${log4j.path}
log4j.level=${log4j.level}

log4j.xml 代码如下：

<?xml version="1.0"?>
