社区版IDEA—导入Eclipse项目注意事项以及非Maven项目如何打包

经过正常导入教程之后。。。

有些jar包没有依赖导入，我这里直接把tomcat的lib全导入

将项目部署输出到tomcat的webapp目录下（注册tomcat服务可以去到bin目录执行service.bat install，如果没配置java环境变量可以直接修改service.bat，加上SET JAVA_HOME=D:\Software\jdk11.0.2），modules菜单里面可以配置编译输出位置

这里有个注意的地方是idea给你部署的tomcat其实是复制了一份你的tomcat配置到user文件夹下面，相当于一个service，在xml文件中可以找到具体指向哪里

非Maven项目如何打包——通过Ant
