1、错误原因
2、解决办法
3、项目放入eclipse中的tomcat环境中,启动、访问
4、项目启动成功

1、错误原因

1.1、新导入的项目报错，说是找不到javax.servlet.http.HttpServlet类，这个类是tomcat安装包lib目录下的jar包，因为导入的项目是我拉取别人开发好的项目，还没有配置本地的环境，所以才出现了这个错误。

2、解决办法

2.1、配置本地的tomcat环境

eclipse工作栏出选择window-preferences

选择与本项目适应的tomcat版本

选择与tomcat版本适应的jre

2.2、在项目中使用本地tomcat环境

选择某个模块，右键Build Path–Configure Build Path

2.3、也直接在某个模块中引入需要的jar包

如下图所示 iam-portal2.0模块缺少删除jar包在这里插入图片描述

2.3、刷新maven

有时候，我们明明导入了依赖，但项目依然报错，这个时候就需要手动刷新maven,如下图所示
