【JavaWeb項目】一個眾籌網站的開發（一）架構搭建

本文轉載自   查看原文   2019-09-04 14:20   1044    Java

本項目是@尚硅谷相關視頻的記錄。

本項目使用Maven構建，工程架構如下圖所示：

 

 

一、公司的公共父工程和工具類包

1.父工程

每個公司都有自己的父工程

父工程作用：對公司使用的jar包進行統一管理，別的工程需要繼承公司的父工程

父工程必須是pom

項目的打包類型：pom、jar、war

pom   --------->   父類型都為pom類型

jar      --------->   內部調用或者是作服務使用

war    --------->   需要部署的項目

packing默認是jar類型

項目中一般使用maven進行模塊管理，每個模塊下對應都有一個pom文件，pom文件中維護了各模塊之間的依賴和繼承關系。項目模塊化可以將通用的部分抽離出來，方便重用；修改一部分代碼不再是build整個項目，縮短了build時間；此外各模塊都有自己的pom文件，結構更清晰。

pom文件除了GAV(groupId, artifactId, version)是必須要配置的，另一個重要的屬性就是packaging打包類型，所有的父級項目的packaging都為pom，packaging默認是jar類型，如果不作配置，maven會將該項目打成jar包。

使用maven進行模塊划分管理，一般都會有一個父級項目，作為父級項目，還有一個重要的屬性，那就是modules，通過modules標簽將項目的所有子項目引用進來，在build父級項目時，會根據子模塊的相互依賴關系整理一個build順序，然后依次build。

而對於各個子項目，需要在其對應的pom文件開頭申明對父級項目的引用，通過GAV實現。對於子項目自己的GAV配置，GV如果不配置，則會從父級項目的配置繼承過來。子模塊可通過dependencies標簽來添加自己的依賴，此外子類項目的packaging值只能是war或者jar。如果是需要部署的項目，則需要打包成war類型，如果只是內部調用或者是作服務使用，則推薦打包成jar類型。

1)創建新的工作集，命名為scw

 

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

 

2)創建父工程

 

pom文件：

公司除了父工程以外，長年累月還會積累很多工具類，這些常用的工具類會存放在同一個地方。

繼承公共父工程

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

該包可能會用到公共依賴，引入公共依賴

 

二、項目的父工程

下面開始我們自己工程的構建

我們的項目也需要一個父工程，scw-parent，選擇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>

繼承公司的公共父工程project-parent

 

三、項目分模塊

我們的項目是分模塊構建的

新建一個項目，這個項目聚合了后台功能的各個模塊，因此打包方式要選pom，這樣才可以在該項目下創建maven模塊

 

 

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>

繼承項目父工程scw-parent

項目分為四個模塊manager-pojo、manager-dao、manager-service和manager-web

pojo里是常用的JavaBean

service里是業務邏輯

dao是數據庫相關

 

四、創建模塊

一共四個模塊manager-pojo、manager-dao、manager-service和manager-web

 

 

 

manager-web要選擇war包，一個聚合父項目應該只有一個war包

右鍵web項目，選擇Build Path，選擇Configure Build Path...

選Project Facets

Eclipse的Project Facets屬性

我們創建了war包，但是web項目還沒配置好，還要重新選擇並配置Dynamic Web Mobile，設置webapp的路徑。

取消Dynamic Web Mobile，點apply，再重新選中

出現下面紅線內容，點擊

Content directory輸入src/main/webapp

webapp在項目中的位置如下圖：

 

 

 

五、各模塊間依賴的配置

四個模塊共同點：都要繼承scw-manager，因此都有：

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

 

dao依賴pojo，service依賴dao，web依賴service

dao的pom.xml

不必配置依賴

<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依賴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依賴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依賴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，各個項目依賴關系建立好，依賴的模塊可以使用被依賴模塊的jar包，如commons引入service后，web也可以使用，但是上層的無法使用。

 

<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">

service引入公司的工具類commons依賴和IOC框架，除MVC以為的Spring框架

六、測試

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

pojo下創建Person

package com.atguigu.scw.manager.bean;

public class Person {}

 

web下創建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";
