        • 步骤

背景

根据电商项目模拟练习后 ,根据个人总结和经验重新进行了分布式项目的框架搭建 , 现总结过程步骤 ,为以后进行相关类型的开发做好基础~~~

项目环境

  • 安装虚拟机
  • 安装 Zookeeper集群( 搭建详情进本人其他博客 )
  • 安装 Maven项目开发工具
  • msql 或oracle数据库支持(本项目选择的是mysql)

项目结构

搭建思路

整体展示

注意: 可以先见这些项目都建好(如上图) ,然后逐一为其添加相关坐标依赖 ,以及相关的配置文件 . 然后根据配置文件创建相应的包名 ,这样就不会导致扫描不到相关的包

知识补充: 如何创建聚合项目的子模块 ?

点击需要聚合其他模块的项目 ,选中状态下 ctrl n ,选中Maven Module

勾选创建简单项目 ,自定义项目名

选则你需要的Maven项目类型即可

搭建步骤

创建父项目 ah-szxy (pom)

添加该项目所用到的 jar包坐标

创建其聚合子模块 ah-szxy-system (pom)

用来聚合项目 ,无需添加jar包坐标

创建 ah-szxy-system的聚合子模块 ah-szxy-system-pojo (jar)

存放实体类 ,无需添加jar包坐标 , 但是请注意要实体类要实现序列化接口

创建 ah-szxy-system的聚合子模块 ah-szxy-system-mapper (jar)

存放dao层接口以及 Mapper文件 , 但是请注意二者所在位置

依赖 mybatis的查询 , 依赖实体类实体 , commo的公共方法 .请根据自己的命名修改第二个第三个依赖

  1. 事务配置文件applicationContext-tx.xml
代码语言:javascript复制

  1. 日志文件 log4j.properties 放在resources根目录下 ,与上面三个文件夹同级 修改包名 log4j.logger.ah.szxy.system.mapper=DEBUG
代码语言:javascript复制
# Global logging configuration
log4j.rootLogger=INFO, stdout
log4j.logger.ah.szxy.system.mapper=DEBUG
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
  1. 测试类 用于通过java手动发布服务 ,在执行ah-szxy-manager-web 项目时 ,需要首先运行这段测试代码 ,代码放在test目录下
代码语言:javascript复制
package an.szxy.system.test;

import java.io.IOException;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class test {
	public static void main(String[] args) {

		ClassPathXmlApplicationContext ac = new ClassPathXmlApplicationContext("spring/applicationContext-*.xml");
		ac.start();

		try {
			System.in.read();
		} catch (IOException e) {
			e.printStackTrace();
		} // 阻塞程序的运行

		ac.stop();
	}
}
  1. 资源打包插件见博文末尾分享1 ,需要项目的根目录下 ,具体请看上面截图

创建其聚合子模块 ah-szxy-manager-web (war)

项目结构

ftp配置文件需要有 vsftpd软件以及相关api的支持 ,暂时不需要 ,故省略不写

相关资料已分享至百度云

步骤
  1. 添加相关jar的坐标 依赖业务层接口,因为要调用相关的服务
代码语言:javascript复制

   <!-- spring容器中存在一个远程服务的代理对象 -->
   <dubbo:reference interface="ah.szxy.system.service.TopicService" id="topicServiceProxy"></dubbo:reference> 
  	
</beans>
  1. applicationContext-service.xml 修改被扫描的包名 ,本项目中业务层实现类包名 ,业务逻辑不复杂时去掉这个扫描
代码语言:javascript复制
<?xml version="1.0" encoding="UTF-8"?>

</beans>

5 .web.xml (创建路径 :webapp/WEB-INF/web.xml) 主要修改如下的标识名(3个) :display-name与servlet的servlet-name和servlet_mapping的servlet-name

代码语言:javascript复制
   <?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"

	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
		<welcome-file>index.htm</welcome-file>
		<welcome-file>index.jsp</welcome-file>
		<welcome-file>default.html</welcome-file>
		<welcome-file>default.htm</welcome-file>
		<welcome-file>default.jsp</welcome-file>
	</welcome-file-list>
	
	<servlet-mapping>

		<url-pattern>/favicon.ico</url-pattern>
	</servlet-mapping>

	<!-- 以监听器的方式启动spring容器 -->
	<listener>

	</listener>

	<!-- 指定spring的配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring/applicationContext-*.xml</param-value>
	</context-param>

	</filter>
	<!-- 映射filter -->
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- springmvc的servlet -->
	<servlet>
		<servlet-name>ah-szxy-manager-web</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- 指定springmvc的配置文件 -->
		<init-param>

			<param-value>classpath:spring/springmvc.xml</param-value>
		</init-param>
		<!-- 让springmvc随系统启动而启动 -->
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>ah-szxy-manager-web</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
</web-app>

6 .webapp目录 webapp下的文件需要自己创建 web.xml已经给出 , jsp页面只要自己写一个index.jsp的页面即可 . 其他资源根据自己需要添加 ,如有需要 ,可下载底部分享的资源

  1. 分布式项目相关资源 链接:https://pan.baidu.com/s/1jFXqIaQ_Y66uydH_7d4BnQ 提取码:vr6h 复制这段内容后打开百度网盘手机App,操作更方便哦
