大致分为以下几个模块(仅是自身经历): 依赖管理工程模块:一般现在开发都是以maven来管理jar包,方便.所以整个工程的依赖统一放在一个单独工程中,一般叫做父工程xxx-parent. 注意事项:父工程打包方式设置成pom 创建父工程时,不要勾选maven模板,他就是一个管理依赖的,不处理业务.如下图 pom文件格式如下:

/properties标签内是下面 dependencies /dependencies标签中的版本号,把它们提取出来,便于方便管理. 把这个工程编译安装进本地仓库,这样后面其他的工程才能使用IDEA中是这样操作 其他模块怎么使用父工程的依赖,下面几个模块介绍 公共工程模块(common):这个工程内放置的是整个项目要用用的公共类,例如日期格式类(DataUtil.java)、分页结果类PafeReult.java、封装JSON结果类JsonResult.java等等…. 创建公共工程(xxx-common),使用maven创建一个java工程,因为它只提供几个类,不做web项目.如图 打包方式为jar包.因为它其中的类需要被别的工程使用.可以在pom.xml文件中写,指定打包方式
packagingjar/packaging继承父工程(xxx-parent).在pom.xml文件中写入如下代码
parentgroupIdcom.qiushiju/groupIdartifactIdxxx-parent/artifactIdversion1.0-SNAPSHOT/version/parent写入本工程实际需要的依赖(从父工程中copy,不需版本信息)比如
dependencies

开发工程模块(比如后台管理系统或者前台管理系统xxx-manager):这个模块一般都是MVC架构,所以需要三个子模块来分开开发以提升效率.三个子模块分别是 xxx-manager-pojo、xxx-manager-controller、xxx-manager-service、xxx-manager-dao。如图项目结构 先说xxx-manager的pom.xml,①它需要继承xxx-parent使用它的依赖,②还有需要加入xxx-common的依赖,要使用其中的工具类 部分代码: packagingpom/packagingparentgroupIdcom.qiushiju/groupIdartifactIdxxx-parent/artifactIdversion1.0-SNAPSHOT/version/parent!-- 依赖管理 --
dependencies!-- 加入common依赖 --dependencygroupIdcom.qiushiju/groupIdartifactIdxxx-common/artifactIdversion1.0-SNAPSHOT/version/dependency.../dependenciesmodulesmodulexxx-manager-pojo/modulemodulexxx-manager-mapper/modulemodulexxx-manager-service/modulemodulexxx-manager-controller/module/modules①从上面代码看到xxx-manager的打包方式要为pom.因为它的几个子模块要使用它的依赖. ②没有别的依赖,因为依赖在四个子模块的各自pom.xml文件中写着,每个模块写各自所需的依赖 ③ module标签,创建一个子模块就会自动出来这一标签~ 现在来说在xxx-manager的基础上创建子项目,方法如下:xxx-manager项目上右键-new-module 同样的步骤创建其他子模块.每个子类创建成功后,在自己的pom.xml文件中都会自动有 parent标签来继承父类,
!-- 继承父类 --parentartifactIdxxx-manager/artifactIdgroupIdcom.qiushiju/groupIdversion1.0-SNAPSHOT/version/parentdependencies!-- controller需要service的依赖, --!-- 在xxx-manager-service的pom文件中,也需要dao层的依赖 --dependencygroupIdcom.qiushiju/groupIdartifactIdxxx-manager-service/artifactIdversion1.0-SNAPSHOT/version/dependency!-- JSP相关 --dependencygroupIdjstl/groupIdartifactIdjstl/artifactId/dependencydependencygroupIdjavax.servlet/groupIdartifactIdservlet-api/artifactIdscopeprovided/scope/dependencydependencygroupIdjavax.servlet/groupIdartifactIdjsp-api/artifactIdscopeprovided/scope/dependency../dependencies特殊的,①pojo,service,dao模块需要打包方式为jar,因为controller需要使用它们的类.而controller模块是需要创建为webapp, ②dao层使用mybatis,因此会有Mapper.xml文件.因此打包时会出错,需要在xxx-manager-dao的pom文件中加入配置代码,代码如下 !-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 --buildresourcesresourcedirectorysrc/main/java/directoryincludesinclude**/*.properties/includeinclude**/*.xml/include/includesfilteringfalse/filtering/resource/resources/buildssm的配置文件写在xxx-manager-controller的src-main-resource目录下与java同级.静态文件放在wabapp下 如果新建的工程没有这三个文件夹,就自己创建.然后mark这个文件夹为相应的资源文件 注意:不管哪一个模块修改,都需要重新编译,打包,安装进仓库,才能时时更新,别的工程才能调用.
