【JavaWeb项目】一个众筹网站的开发（一）架构搭建

本项目是@尚硅谷相关视频的记录。

本项目使用Maven构建，工程架构如下图所示：

一、公司的公共父工程和工具类包

1.父工程

每个公司都有自己的父工程

父工程作用：对公司使用的jar包进行统一管理，别的工程需要继承公司的父工程

父工程必须是pom

项目的打包类型：pom、jar、war

pom   --------->   父类型都为pom类型

jar      --------->   内部调用或者是作服务使用

war    --------->   需要部署的项目

packing默认是jar类型

项目中一般使用maven进行模块管理，每个模块下对应都有一个pom文件，pom文件中维护了各模块之间的依赖和继承关系。项目模块化可以将通用的部分抽离出来，方便重用；修改一部分代码不再是build整个项目，缩短了build时间；此外各模块都有自己的pom文件，结构更清晰。

pom文件除了GAV(groupId, artifactId, version)是必须要配置的，另一个重要的属性就是packaging打包类型，所有的父级项目的packaging都为pom，packaging默认是jar类型，如果不作配置，maven会将该项目打成jar包。

使用maven进行模块划分管理，一般都会有一个父级项目，作为父级项目，还有一个重要的属性，那就是modules，通过modules标签将项目的所有子项目引用进来，在build父级项目时，会根据子模块的相互依赖关系整理一个build顺序，然后依次build。

而对于各个子项目，需要在其对应的pom文件开头申明对父级项目的引用，通过GAV实现。对于子项目自己的GAV配置，GV如果不配置，则会从父级项目的配置继承过来。子模块可通过dependencies标签来添加自己的依赖，此外子类项目的packaging值只能是war或者jar。如果是需要部署的项目，则需要打包成war类型，如果只是内部调用或者是作服务使用，则推荐打包成jar类型。

1)创建新的工作集，命名为scw

在Eclipse中使用Working set管理项目 https://jingyan.baidu.com/article/e4511cf343a3f22b845eaf21.html

2)创建父工程

pom文件：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Maven中POM.XML详解 https://www.cnblogs.com/sharpest/p/5969566.html

这个pom.xml主要由三部分组成：GAV等信息，properties和dependencyManagement，properties指定了依赖的版本，dependencyManagement指定了依赖。

用到的依赖：

公共依赖	commons-io
	commons-lang3
	commons-codec
	commons-beanutils
	commons-collections
	commons-math3
	commons-fileupload
	commons-email
数据库	druid 连接池
	mysql-connector-java 驱动
基础框架	Spring
	mybatis
WEB类库	jsp-api
	servlet-api
	jstl
日志	log4j
	slf4j-log4j12
	slf4j-api
工作流	activiti-engine
	activiti-spring
其他	mybatis-generator-core
	jackson
	pagehelper 分页
	junit
	joda-time 时间
	httpclient
	poi 文档操作
	quartz 石英调度

2.公司工具类的包

公司除了父工程以外，长年累月还会积累很多工具类，这些常用的工具类会存放在同一个地方。

建立新的maven工程

继承公共父工程

maven继承 https://www.cnblogs.com/huanggy/p/9736756.html

该包可能会用到公共依赖，引入公共依赖

二、项目的父工程

下面开始我们自己工程的构建

我们的项目也需要一个父工程，scw-parent，选择pom

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.atguigu.project</groupId>
    <artifactId>project-parent</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <groupId>com.atguigu.scw</groupId>
  <artifactId>scw-parent</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>pom</packaging>
</project>

继承公司的公共父工程project-parent

三、项目分模块

我们的项目是分模块构建的

新建一个项目，这个项目聚合了后台功能的各个模块，因此打包方式要选pom，这样才可以在该项目下创建maven模块

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.atguigu.scw</groupId>
  <artifactId>scw-manager</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>pom</packaging>
  
  <parent>
    <groupId>com.atguigu.scw</groupId>
    <artifactId>scw-parent</artifactId>
    <version>0.0.1-SNAPSHOT</version>    
  </parent>
 
  <modules>
      <module>manager-pojo</module>
      <module>manager-dao</module>
      <module>manager-service</module>
      <module>manager-web</module>
  </modules>
</project>

继承项目父工程scw-parent

项目分为四个模块manager-pojo、manager-dao、manager-service和manager-web

pojo里是常用的JavaBean

service里是业务逻辑

dao是数据库相关

四、创建模块

一共四个模块manager-pojo、manager-dao、manager-service和manager-web

manager-web要选择war包，一个聚合父项目应该只有一个war包

右键web项目，选择Build Path，选择Configure Build Path...

选Project Facets

Eclipse的Project Facets属性

我们创建了war包，但是web项目还没配置好，还要重新选择并配置Dynamic Web Mobile，设置webapp的路径。

取消Dynamic Web Mobile，点apply，再重新选中

出现下面红线内容，点击

Content directory输入src/main/webapp

webapp在项目中的位置如下图：

五、各模块间依赖的配置

四个模块共同点：都要继承scw-manager，因此都有：

  <parent>
    <groupId>com.atguigu.scw</groupId>
    <artifactId>scw-manager</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>

dao依赖pojo，service依赖dao，web依赖service

dao的pom.xml

不必配置依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.atguigu.scw</groupId>
    <artifactId>scw-manager</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <artifactId>manager-pojo</artifactId>
</project>

dao依赖pojo

dao的pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

      <dependency>
          <groupId>com.atguigu.scw</groupId>
          <artifactId>manager-pojo</artifactId>
          <version>0.0.1-SNAPSHOT</version>
      </dependency>
  </dependencies>
</project>

service依赖dao

service的pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.atguigu.scw</groupId>
    <artifactId>scw-manager</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <artifactId>manager-service</artifactId>
  
  <dependencies>
      <dependency>
          <groupId>com.atguigu.scw</groupId>
          <artifactId>manager-dao</artifactId>
          <version>0.0.1-SNAPSHOT</version>
      </dependency>
  </dependencies>
  
</project>

web依赖service

web的pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.atguigu.scw</groupId>
    <artifactId>scw-manager</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <artifactId>manager-web</artifactId>
  <packaging>war</packaging>
  
  <dependencies>
      <dependency>
          <groupId>com.atguigu.scw</groupId>
          <artifactId>manager-service</artifactId>
          <version>0.0.1-SNAPSHOT</version>
      </dependency>
  </dependencies>
</project>

聚合好后，各个项目依赖关系建立好，依赖的模块可以使用被依赖模块的jar包，如commons引入service后，web也可以使用，但是上层的无法使用。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

六、测试

SprngMVC概述 https://www.cnblogs.com/aidata/p/11458825.html

pojo下创建Person

package com.atguigu.scw.manager.bean;

public class Person {}

web下创建HelloController

package com.atguigu.scw.manager.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.atguigu.scw.manager.bean.Person;

@Controller
public class HelloController {

    
    @RequestMapping("hello")
    public String hello() {
        Person person = new Person(); 
        return "/success.jsp";
    }
}

web src/main/resources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"

    <context:component-scan base-package="com.atguigu"></context:component-scan>

</beans>

webapp下

创建index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
    <a href="hello">hello</a>
</body>
</html>

success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>你好</h1>
</body>
</html>

前端控制器

        <servlet-name>springDispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

运行tomcat，浏览器访问

使用IDEA

项目规范

命名规范：驼峰命名法，拒绝拼音

接口与实现类

UserService（接口） ------ UserServiceImpl（实现类） ------ BaseService（基类）

Java类命名 驼峰命名法

变量命名：驼峰命名法，POJO全部自动生成getter/setter；布尔属性命名不用isXxx

包名：统一com.atguigu.scw.模块名.包名

web项目的页面：index.jsp，login.jsp，不能直接访问的页面统一放在/WEB-INF/jsp/目录下

项目名：全小写

注释：注释模板统一；不要有过多注释，关键的if判断必须加注释，每个类每个方法上必加注释

统一svn版本库

创建maven项目

 删除掉src目录

新建模块

            

web项目
