SSH项目实战OA-使用maven搭建工程

这里，我统一规范一下OA项目的开发工具和环境，如下：

开发工具和环境

Eclipse

Maven

Tomcat-8.0.30

JDK 1.8

MySQL 5.5

后台工程搭建:

Maven常见的打包方式有：

jar

jar工程，很显然就是pom工程的子工程，由pom工程来管理。

war

war工程是一个web工程，是可以直接放到tomcat下运行的工程。

pom

pom工程一般都是父工程，管理jar包的版本、maven插件的版本、统一的依赖管理，它是一个聚合工程。其实说白了它只有一个pom.xml文件，一般是作为父工程出现的，只是定义了一些依赖、插件、还有一些版本号等等。

工程之间的依赖关系如下：

搭建OA-parent工程

在pom.xml中锁定jar包的版本,注意的是,在pom.xml中仅仅是锁定了jar包的版本,但是没用真正的添加了jar包的依赖,这样是为了当OA-parent的子模块不用导入一些模块并不需要的jar包,但又可以使不同模块之中的相同jar包锁定在同一版本,不会发生因版本不同而发生冲突

            </plugin>
        </plugins>
	</build>
  

</project>

搭建OA-common工程

接下来，我们来给OA-common工程的pom.xml文件添加依赖,这个工程是用来存放所有工程都可能用到的公共组件,所以在pom.xml中添加公共的依赖.由于已经在OA-parent中定义了jar包的版本,所以在子模块中添加依赖的时候,不用也不要指定jar包版本

         </dependency>
    </dependencies>
</project>

搭建OA-system工程

 

 

 

 

搭建好OA-system后,由于OA-common是公共工程,所以需要在OA-system的pom.xml引入对OA-common的依赖

<dependencies>
  	<dependency>
  		 <groupId>com.QEcode</groupId>
   		  <artifactId>OA-common</artifactId>
    	<version>0.0.1-SNAPSHOT</version>
  	</dependency>
  	
  </dependencies>

 

下面我们在来添加属于该聚合工程的四个模块。

搭建OA-system-pojo工程

 

由于OA-system-pojo不用依赖任何其他jar包,仅仅用来给其他模块提供实体类,所以不用引入依赖

搭建OA-system-dao工程

 

由于该工程是持久层,所以肯定需要OA-system-pojo的依赖,此外还需要有关数据库操作的依赖:hibernate,mysql,连接池.pom.xml如下

<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">

  	<!-- hibernate -->

	</dependency>
  	<!-- MySql -->
      <dependency>

          <artifactId>mysql-connector-java</artifactId>
      </dependency>
      <!-- 连接池 -->
      <dependency>
          <groupId>com.alibaba</groupId>
          <artifactId>druid</artifactId>
      </dependency>
  </dependencies>
  
  
  
</project>

搭建OA-system-interface工程

这个工程是服务层接口,被web层和service层所引用,在service层实现接口.在web层使用接口.

OA-system-interface工程的创建和上面工程创建的方法一样,

 

该工程也需要OA-system-pojo的依赖

<dependencies>
  <!-- pojo -->
  <dependency>
   <groupId>com.QEcode</groupId>
    <artifactId>OA-system-pojo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </dependency>
 
  </dependencies>

搭建OA-system-service工程

由于其他OA-system-*的工程都是jar包,我们是无法直接启动的,所以最后需要创建一个war工程来引用这些jar工程,将其聚合起来.

现在考虑要引入哪些依赖?

OA-system-service是服务层,所以必须引入dao层,此外由于我们这个项目是SSh实战项目,所以也需要引入spring的依赖,此外我们需要服务层接口interface

在添加依赖后,会发现OA-system-service工程报错,这是因为这个是一个web工程,而maven创建的工程是没有web.xml文件的,所以会报错.解决的办法很简单:创建一个web.xml文件.你可以自己在webapp目录下创建WEB-INF/web.xml,不过有个更简单的方法.

右击OA-system-service工程

在点击之后就会自动生成web.xml文件,工程就不会报错

搭建OA-system-web工程

这个工程是OA-system的表现层工程,

 

接下来要添加依赖:spring的依赖是必须的,此外还需要jsp的组件和struts2的依赖

由于这个是web工程,所以也需要创建web,xml文件,创建方法和上面的相同
