后端开发环境搭建和启动报错

15229892921

各位大哥，初次接出jeecg-boot，在搭建环境时遇到了一些错误，希望能得到一些指点；

1、这个问题是按照maven的方式导入zip包解压后的项目，报错如下：

这是缺少servlet-api.jar包，我导入后不再报错了（教程中并没有，我觉得这样可能不对）


2、导入之后运行启动类，报错如下 ：           2019-05-11 15:16:19.197 [main] INFO  org.jeecg.JeecgApplication:50 - Starting JeecgApplication on Hesong with PID 476 (D:\Users\Hesong\Documents\eclipse-workspace\jeecg-boot-master\jeecg-boot\target\classes started by Hesong in D:\Users\Hesong\Documents\eclipse-workspace\jeecg-boot-master\jeecg-boot)
