maven構建spring mvc專案 + Mybatis整合
阿新 • • 發佈：2019-01-23
一、新建專案
1、File>New>Other>Maven>Maven Project, 點選Next
2、選擇專案儲存路徑。然後點選Next。
3、選擇專案型別，在Artifact Id中選擇maven-archetype-webapp，然後點選Next。
4、Group ID一般寫大專案名稱。Artifact ID是子專案名稱。
例如Spring的web包，Group ID：org.springframework，artifactId：spring-web。
Package是預設給你建一個包，不寫也可以。
填完後，點選Finish。
5、建好後的專案結構如下：
6、開啟cmd命令視窗，cd到專案的跟目錄。執行以下語句：
mvn clean eclipse:eclipse
注：
mvn clean //清理（刪除target目錄下編譯內容）
mvn eclipse:eclipse //生成Eclipse專案結構
7、選中專案，右擊：New>Other>java>Source Folder，點選Next
8、以下Floder Name必須為src/main/java
9、現目錄結構如下：
二、配置檔案設定（附部分配置說明）
1、pom.xml

自動掃描元件，可以寫多個。component-scan 預設掃描的註解型別是 @Component，
不過，在 @Component語義基礎上細化後的 @Repository、 @Service 和 @Controller
也同樣可以獲得 component-scan 的青睞

<mvc:annotation-driven /> 是一種簡寫形式，完全可以手動配置替代這種簡寫形式，會自動註冊
DefaultAnnotationHandlerMapping與AnnotationMethodHandlerAdapter 兩個bean,
是spring MVC為@Controllers分發請求所必須的。

<mvc:annotation-driven />
<!--
配置js,css等靜態檔案直接對映到對應的資料夾，不被DispatcherServlet處理
若將以下改為：<mvc:default-servlet-handler />則使用預設的Servlet來響應靜態檔案
-->
