Java 框架基礎教程 : 使用Maven快速搭建SSM項目(Idea)

這篇文章主要講如何使用Maven快速搭建SpringMVC+Spring+ mybatis項目

Maven的安裝與配置以及創建一個web項目可以看下面這篇博文

Java框架基礎教程 : Maven安裝與配置以及在IDEA中使用Maven創建一個web項目

一.創建一個Maven項目,將Create from archetype(原型)勾選上

然後next

接下來點擊Finish,等待maven下載所需的依賴包,項目就已經搭建好了

二.配置SSM環境

1.修改項目目錄

2.配置相關配置文件

pom.xml

  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  <maven.compiler.source>1.7</maven.compiler.source>
  <maven.compiler.target>1.7</maven.compiler.target>
  <junit.version>4.12</junit.version>
  <!-- 設置項目編碼編碼 -->
  <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
  <!-- spring版本號 -->
  <spring.version>4.3.5.RELEASE</spring.version>
  <!-- mybatis版本號 -->
