Spring集成Dubbo 3.x脚手架

文章导读：
1、介绍文章内容的版本依赖
2、创建Spring基础工程
3、修改基础工程的配置文件
4、增加dubbo 3的依赖包管理
5、建立子工程演示
6、修改子工程的POM配置文件
7、增加Spring配置文件
8、增加log4j配置文件

1、相关依赖版本

依赖 版本
Spring 5.x
dubbo 3.X
maven 3.5.x

2、创建Spring基础工程

创建一个基础演示工程
创建Maven基础工程
Maven坐标设置，各位可以根据自己情况设置
设置Maven相关内容

备课和讲课的电脑可能不一样，所以讲课的时候可能物理位置不是这个，哈哈！~

创建成功以后的截图

由于父工程只管理依赖包，不会有任何代码，所以删除掉src目录

3、修改配置文件

原始配置文件如下：

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

<!--      </plugins>-->
<!--    </pluginManagement>-->
<!--  </build>-->
</project>

4、增加dubbo 3的依赖包管理

1、在pom.xml 中的properties中增加dubbo的版本号配置

<properties>
    <java.version>1.8</java.version>
    <!-- 增加dubbo版本号控制 -->
    <dubbo.version>3.0.0.preview</dubbo.version>
</properties>

2、在pom.xml中，增加dependencyManagement相关的依赖管理

    <dependencyManagement>
        <dependencies>
            <!-- 增加dubbo依赖包管理 -->
            <dependency>
                <groupId>org.apache.dubbo</groupId>
                <artifactId>dubbo</artifactId>
                <version>${dubbo.version}</version>
            </dependency>
            <dependency>
                <groupId>org.apache.dubbo</groupId>
                <artifactId>dubbo-dependencies-zookeeper</artifactId>
                <version>${dubbo.version}</version>
                <type>pom</type>
            </dependency>
        </dependencies>
    </dependencyManagement>

5、建立子工程示例

建立子模块

重复建立父工程时的步骤


建立Maven依赖
设置Maven坐标
设置Maven信息

删除掉课程无用信息

6、修改子工程的POM配置文件

6.1 修改子工程的POM配置文件

配置文件位置：


修改子工程POM文件位置

7、增加Spring配置文件

增加配置文件目录：resources

增加配置文件目录

配置resources目录为资源目录

修改工程设置

设置资源目录

添加Spring默认配置文件
在resources目录下创建Spring配置文件：applicationContext.xml，截图如下：

创建Spring配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"
       xsi:schemaLocation="
            http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
            http://dubbo.apache.org/schema/dubbo
            http://dubbo.apache.org/schema/dubbo/dubbo.xsd">

    
</beans>

修改父工程的POM文件，增加依赖包的版本控制【父工程POM位置可以见最后】

    <!-- Spring MVC -->

启动类中增加启动读取配置文件

import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.io.IOException;

/**
 * Hello world!
 *
 */
public class App 
{
    public static void main( String[] args ) throws IOException {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

        context.start();

        System.in.read(); // 按任意键退出

    }
}
完成以后截图

8、增加log4j配置文件

在子工程的resources目录中增加一个log4j.xml文件，并且填入如下内容：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration PUBLIC "-//log4j/log4j Configuration//EN" "log4j.dtd">

<log4j:configuration>
    <appender name="console" class="org.apache.log4j.ConsoleAppender">
        <!-- 日志输出格式 -->
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="[%p][%c]-[%m]%n"/>
        </layout>
        <!--过滤器设置输出的级别-->
        <filter class="org.apache.log4j.varia.LevelRangeFilter">
            <!-- 设置日志输出的最小级别 -->
            <param name="levelMin" value="INFO"/>
            <!-- 设置日志输出的最大级别 -->
            <param name="levelMax" value="ERROR"/>
        </filter>
    </appender>

    <root>
        <appender-ref ref="console"/>
    </root>
</log4j:configuration>

截图如下：
