1.javaweb環境搭建

2maven搭建參考(這裡的tomcat配置有問題，tomcat可以參考上面)

[email protected]或者需要用到的註解無法使用或找到的時候如圖

直接選擇第三個add maven。如果發現maven無法找到內容的時候可以這樣解決

如果上面方法不能解決，那麼還有個方法。將需要匯入的依賴copy下來，然後百度搜索

如圖：

紅色字型是需要匯入的包，然後直接百度搜這個包的maven依賴

然後將想下面這樣的程式碼考入pom.xml資料夾下面即可（pom.xml是用來匯入依賴的存在，相當於android的依賴庫）

<dependency>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-war-plugin</artifactId>
   <version>3.2.0</version>
</dependency>
 

如果覺得這樣實在麻煩，那麼下面檔案中總結了平時開發所需的開發依賴，直接匯入到pom.xml即可，然後構建幾遍就可以使用（注意的是groupid和artifactid改成自己建立時候的）：
