使用intelliJ IDE開發java web項目

 <!-- spring版本號 -->

<spring.version>4.3.0.RELEASE</spring.version>

<!-- mybatis版本號 -->
<mybatis.version>3.4.4</mybatis.version>

<!-- mysql驅動版本號 -->
<mysql-driver.version>5.1.40</mysql-driver.version>

<!-- log4j日志包版本號 -->
<log4j.version>2.7</log4j.version>
<commons-logging.version>1.2</commons-logging.version>

<!-- 對象轉 jackson 版本號 -->

使用maven 開發springmvc apring mybatis web項目。

1.File -> New Project ，進入創建項目窗口

 

 2 出現以下界面 

3 按照如上選項進行點擊，點next

4 上面兩項隨便填，點擊next

上面選項中可以直接使用默認配置。我修改的local repository是本地倉庫位置，可以改也可以不改。下面在Properties中添加一個參數 archetypeCatalog=internal，不加這個參數，在maven生成骨架的時候將會非常慢，有時候直接卡住。來自網上的解釋：archetypeCatalog表示插件使用的archetype元數據，不加這個參數時默認為remote，local，即中央倉庫archetype元數據，由於中央倉庫的archetype太多了所以導致很慢，指定internal來表示僅使用內部元數據。

5 點擊next

這個我沒有修改，點擊finish

6 生成maven的項目骨架之后，我們還需要手動在 src/main 下創建 java目錄。現在可以直接編寫了

 到此為止，項目的框架基本搭建完成。

 

7 下面進行pom.xml進行配置

寫完pom.xml文件后需要更新依賴，

點擊更新。

 

 8 按照常規步驟開發SSM項目即可。

可以參考SSM整合開發流程

 

9 spring.xml項目配置，mybatis配置文件指定，spring配置，springMVC配置

10 項目部署，這幾步很關鍵。可以參考 圖文詳解 IntelliJ IDEA 15 創建普通 Java Web 項目

 

 

常見問題

1 maven項目中java文件夾不能新建package和class，需要做如下設置

 

2 在idea中安裝mybatis插件

選擇file -> setting -> plugins，搜索mybatis，這時因為沒有安裝過插件，所以會出現如圖所示：

點擊Browse，這是會彈出如下窗口，intellij idea會自動從網絡搜索插件，方便下載，如圖所示：

點擊Install plugin即可自動下載安裝，之后重啟intellij idea即可。

 

3 在進行mapper文件映射時出現 URI is not registered.解決辦法如下

鼠標點擊紅色字，然后Intellij出現小紅燈，選擇Fetch external resource即可解決 

 

4 MAVEN項目jar包依賴導入問題解決，

在新建項目后，項目的路徑中會生成pom.xml文件和項目名.iml文件。新建項目后，IDEA不會自動刷新Maven的依賴。刷新Maven配置的方法為：

（1）右鍵單擊項目；

（2）在彈出菜單中選擇Maven|Reimport菜單項。

此時，IDEA將通過網絡自動下載相關依賴，並存放在Maven的本地倉庫中。
