分布式项目搭建

备注：

Maven的常见打包方式：jar、war、pom

1.pom工程：用在父级工程或聚合工程中。用来做jar包的版本控制。

2.war工程：将会打包成war，发布在服务器上的工程。如网站或服务。

3.jar工程：将会打包成jar用作jar包使用。

1. 项目结构

xm-parent：父工程，打包方式pom，管理jar包的版本号。

    |           项目中所有工程都应该继承父工程。

|--xm-shop：服务层工程。聚合工程。Pom工程

|--xm-shop-dao：打包方式jar

|--xm-shop-model：打包方式jar

|--xm-shop-interface：打包方式jar

|--xm-shop-service：打包方式：war

|--xm-shop-web：表现层工程。打包方式war

 

2. 新建xm-parent

在xm-shop下新建模块xm-shop-service（war）

由于项目发布需要war包，因此该模块打包成war

添加web.xml

1 <?xml version="1.0" encoding="UTF-8"?>
2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

1. 工程启动

启动xm-shop工程

需要在xm-shop 的pom工程中，配置tomcat插件。启动的端口号，和工程名称。

在xm-shop的pom文件中添加如下配置：

 1 <!-- 配置tomcat插件 -->
 2     <build>
 3         <plugins>
 4             <plugin>
 5                 <groupId>org.apache.tomcat.maven</groupId>
 6                 <artifactId>tomcat7-maven-plugin</artifactId>
 7                 <configuration>
 8                     <port>8080</port>
 9                     <path>/</path>
10                 </configuration>
11             </plugin>
12         </plugins>
13     </build>

启动tomcat插件：

clean tomcat7:run

先把xm-parent安装到本地仓库。然后再启动。
