搭建基于Duboo、ZooKeeper、RPC的分布式SpringMVC项目

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

在这里插入图片描述

整体展示

在这里插入图片描述

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
在这里插入图片描述
勾选创建简单项目 ,自定义项目名
在这里插入图片描述
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

在这里插入图片描述

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. 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
# 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
    在这里插入图片描述
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

在这里插入图片描述

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
在这里插入图片描述

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

   <!-- 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
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

   <!-- 加载属性文件 -->
   <!-- <context:property-placeholder location="classpath:resources/ftp.properties"/> -->
   
   <context:component-scan base-package="ah.szxy.system.service.impl" />
   
</beans>
  1. springmvc.xml

      <property name="maxUploadSize" value="5242880"></property>
   </bean>

</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


   <?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>
		<servlet-name>default</servlet-name>
		<url-pattern>/favicon.ico</url-pattern>
	</servlet-mapping>

	<!-- 以监听器的方式启动spring容器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</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>

	<!-- POST请求的乱码过滤器 -->
	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<!-- 指定编码方式 -->
		<init-param>
			<param-name>encoding</param-name>
			<param-value>utf-8</param-value>
		</init-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-name>contextConfigLocation</param-name>
			<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

在这里插入图片描述

  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 ↩︎ ↩︎

深入理解 Mocha 测试框架：从零实现一个 Mocha

前言什么是自动化测试自动化测试在很多团队中都是Devops环节中很难执行起来的一个环节，主要原因在于测试代码的编写工作很难抽象，99%的场景都需要和业务强绑定，而且写测试代码的编写工作量往往比编写实际业务代码的工作量更多。在一些很多业务场景中投入产出比很低，适合写自动化测试的应该是那些中长期业务以及一些诸如组件一样的基础库。自动化测试是个比较大的概念，其中分类也比较多，比如单元测试，端对端测试，集

(20200916 Solved)docker-compose up创建容器自动退出

问题描述如题，创建容器后自动退出了。并且docker start container无效解决方案原因是缺失了控制终端的配置，需要在docker-compose.yml中增加tty:true ，有时候这样也不行，需要再增加一个command:/bin/bash，命令不一定是这个，需要是一个不会退出的命令，然后用-d后台启动容器。Referencesdocker-compose启动容器后自动退出...
