先說項目使用Maven的好處
1、項目構建。Maven定義了軟件開發的整套流程體系,並進行了封裝,開發人員只需要指定項目的構建流程,無需針對每個流程編寫自己的構建腳本。
2、依賴管理。除了項目構建,Maven最核心的功能是軟件包的依賴管理,能夠自動分析項目所需要的依賴軟件包,併到Maven中心倉庫去下載。
A)管理依賴的jar包
B)管理工程之間的依賴關係。
傳統工程結構
Maven管理的工程結構:
不使用maven:工程部署時需要手動複製jar包。完成工程構建。非常繁瑣。
使用maven進行工程構建:
使用maven可以實現一步構建。

至此我們的工程建立完成,我們需要測試這個工程能不能用還需要配置如下
8.配置tomcat插件
運行web工程需要添加一個tomcat插件。插件必須添加到spring-manager工程中。因爲spring-manager是聚合工程。在運行時需要把子工程聚合到一起才能運行。

- <plugins>
- <plugin>

- <configuration>
- <port>8080</port>
- <path>/</path>
- </configuration>
- </plugin>
- </plugins>
