maven 新建站点

1. 站点建立步骤
   启动eclipse_sts--->新建项目--->搜索maven -->选择maven-archetype-webapp
   
   
2. 红色错误配置
   新建项目完成后--->index.jsp 出现红色错误--->原因在于没有为index.jsp指定运行环境如tomcat
   操作:选择站点——>右键-->build path--> limbraris-->add limbraris->选择server run 服务器运行环境
   本选择是tomcat8.5 具体你的根据你自己情况
3. 1. pom.xml 架包jar

                  <version>5.1.25</version>
              </dependency>

      如上代码中：
      <!-- 添加mybatis  jar -->

   2.         <dependency>
                  <groupId>org.mybatis</groupId>
                  <artifactId>mybatis</artifactId>
                  <version>3.5.2</version>
              </dependency>
              <dependency>

   3.  特别强调：查看 mybatis架包是不成功
      到java build config-->libraries->maven dependeces -->查看mybatis3.5.2.jar
