本项目使用Maven构建，工程架构以下图所示：前端

 

 

1、公司的公共父工程和工具类包

1.父工程

每一个公司都有本身的父工程java

父工程做用：对公司使用的jar包进行统一管理，别的工程须要继承公司的父工程mysql

父工程必须是pomgit

项目的打包类型：pom、jar、wargithub

pom   --------->   父类型都为pom类型web

jar      --------->   内部调用或者是做服务使用spring

war    --------->   须要部署的项目sql

packing默认是jar类型数据库

项目中通常使用maven进行模块管理，每一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。项目模块化能够将通用的部分抽离出来，方便重用；修改一部分代码再也不是build整个项目，缩短了build时间；此外各模块都有本身的pom文件，结构更清晰。

pom文件除了GAV(groupId, artifactId, version)是必需要配置的，另外一个重要的属性就是packaging打包类型，全部的父级项目的packaging都为pom，packaging默认是jar类型，若是不做配置，maven会将该项目打成jar包。

使用maven进行模块划分管理，通常都会有一个父级项目，做为父级项目，还有一个重要的属性，那就是modules，经过modules标签将项目的全部子项目引用进来，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，而后依次build。

而对于各个子项目，须要在其对应的pom文件开头申明对父级项目的引用，经过GAV实现。对于子项目本身的GAV配置，GV若是不配置，则会从父级项目的配置继承过来。子模块可经过dependencies标签来添加本身的依赖，此外子类项目的packaging值只能是war或者jar。若是是须要部署的项目，则须要打包成war类型，若是只是内部调用或者是做服务使用，则推荐打包成jar类型。

1)建立新的工做集，命名为scw

 

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

 

2)建立父工程

 

pom文件：

2.公司工具类的包

公司除了父工程之外，终年累月还会积累不少工具类，这些经常使用的工具类会存放在同一个地方。

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

 

2、项目的父工程

下面开始咱们本身工程的构建

咱们的项目也须要一个父工程，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

 

3、项目分模块

咱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，所以打包方式要选pom，这样才能够在该项目下建立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里是经常使用的JavaBean

service里是业务逻辑

dao是数据库相关

 

4、建立模块

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

咱们建立了war包，可是web项目还没配置好，还要从新选择并配置Dynamic Web Mobile，设置webapp的路径。

取消Dynamic Web Mobile，点apply，再从新选中

出现下面红线内容，点击

Content directory输入src/main/webapp

webapp在项目中的位置以下图：

 

 

 

5、各模块间依赖的配置

四个模块共同点：都要继承scw-manager，所以都有：

<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

没必要配置依赖

<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">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.atguigu.scw</groupId>
    <artifactId>scw-manager</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <artifactId>manager-dao</artifactId>
  
  <dependencies>
      <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，各个项目依赖关系创建好，依赖的模块可使用被依赖模块的jar包，如commons引入service后，web也可使用，可是上层的没法使用。

 

<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">

  <parent>
    <groupId>com.atguigu.scw</groupId>

      </dependency>

          <artifactId>mybatis-generator-core</artifactId>
      </dependency>
      
  </dependencies>
</project>

 

service引入公司的工具类commons依赖和IOC框架，除MVC觉得的Spring框架

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

pojo下建立Person

package com.atguigu.scw.manager.bean; public class Person {}

 

web下建立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"; } }

<head>
<meta charset="UTF-8">
<title>Insert title here</title>

<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>
