博客系统项目搭建

Posted 别人放弃，我依旧坚持

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了博客系统项目搭建相关的知识，希望对你有一定的参考价值。

一.maven工程的好处

　　1.一步构建

　　maven对项目构建的过程进行标准化，通过一个命令即可完成构建过程。

　　2.依赖管理

　　maven为全世界的java开发者提供了一个免费的中央仓库，在其中几乎可以找到任何的流行开源软件。通过衍生工具，我们还能对其进行快速搜索，因此maven工程不用手动导入jar包，可以通过在pom.xml中定义坐标从中央仓库自动下载，方便并且不容易出错。

　　3.maven的跨平台，可在window、linux上使用。

　　4.maven遵循规范开发有利于提高大型团队的开发效率，降低项目的维护成本，大公司基本上都会考虑使用maven来构架项目。

二.工程搭建分析

　　1.Maven的常见打包方式为：jar、war、pom三种方式。

　　2.Pom工程一般都是作为父工程用来管理jar包的版本、maven插件的版本、统一的依赖管理。

　　3.聚合工程：分组分模块开发，每个模块开发完成要运行整个工程需要将每个模块聚合在一起运行，聚合工程 打包方式pom。

　　4.war工程一般是作为表现层（web层）打包方式。

三.工程搭建

　　开发环境：eclipse-jee-oxygen-R-win32-x86_64

　　Maven版本：3.3.9

　　本地仓库默认位置：C:\\Users\\Administrator\\.m2

　　我修改本地仓库的位置为：E:\\Users\\local\\repository

 

1.blog-parent工程。（pom工程）

（1）创建一个maven项目

 

（2）打包方式为pom

（3）pom.xml文件

8.blog-manager-web（表现层，blog-manager服务层工程的maven模块，打包方式为war。）

（1）创建blog-manager-web  模块

（2）创建完成项目报错，原因是目录结构不完整，在webapp目录下缺少 WEB-INF目录和该目录下的web.xml文件。

 

解决方法一：可以手动创建，补全该目录和和该目录下的文件。

  • web.xml

<?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"  xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"  version="2.5">
  <display-name>blog-manager-web</display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
</web-app>
View Code

  • 解决方法二：如下图：

（4）添加欢迎页，运行启动blog-manager工程。

  •  index.jsp

<%@ page language="java" contentType="text/html;  charset=utf-8"
    pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01  Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;  charset=utf-8">
<title>首页</title>
</head>
<body>
     <h1>博客系统首页</h1>
</body>
</html>
测试首页

  • 把blog-parent、blog-common安装到本地仓库。然后再启动。安装过程如下：

  • 运行blog-manager工程。

  • 项目搭建成功
