idea eclipse web项目
（一）导入项目
导入项目后会有很多报错，原因是各种依赖没有引入。下面讲讲如何具体解决
1）处理Project
如图显示1先new一个jdk环境，这个选择本地的就好
2则选择对应jdk版本的特性
3是选择编译后class文件输出的目录
2）处理Modules
Modeules是Project的子模块
修改src目录为Sources，resource为Resources
修改编译输出路径（有没有发现这和之前的project一样哎，废话因为Modules是Project的子模块，此处是但Modules的Project所以这里的设置和前面是一样的）
将eclipse的web项目的中lib文件里的jar引入到此项目中
add一个web
修改Path为你项目的web.xml的地址
修改Web Resource Directory将其指向导入的web项目的WebContent路径
3）处理Libraries中的信息
向Libraries中添加jar，这里和Modules中Dependencies中的区别是他是模块共享的
此处添加的Tomcat中包含servlet的api的jar
4）处理Artifacts
选择打war的模块
此处的Output directory随便搞个地方都无所谓的
（二）配置容器，我这边是Tomcat
首先添加一个Tomcat
Server基本不用做什么修改
Deployment这个地方需要注意下Application context默认是/，当项目启动时（以我本地为例），访问项目通过url：localhost:8080/index.html有没有觉得和正常的eclipse启动的不太一样？
没错，这边的端口号后面直接就是访问的页面的路径了，并没有带项目名。如果你想想eclipse那样的话只需修改Application context的值在/后写你的项目名即可。这时候访问地址就变成了localhost:8080/项目名/index.html
Logs配置的是选择输出的log
这么一个截图大概就能明白了
（三）启动项目
这里我故意修改下我的数据库连接信息，让其报错。来直观体验下。
先贴下在eclipse中启动报错的样子
看了后很直观，是哪边出错了。
现在贴下idea中一开始发现的错误的显示
- -！图帖不了了，就直接copy了

我发现了这么条信息Error during artifact deployment. See server log for details.
然后我翻到项目启动时打印的信息
D:\development\tomcat\apache-tomcat-7.0.70\bin\catalina.bat run [2017-03-28 08:40:34,220] Artifact sms-interface-monitor:war exploded: Server is not connected.

我就去了C:\Users\Administrator\.IntelliJIdea2016.3\system\tomcat\Unnamed_sms-interface-monitor_2
进入到logs目录下就会看到一堆日志文件也就是（二）中最后的截图的样子
打开localhost.2017-03-28.log其中一段就是
（到家了，终于又可以贴图了）
这个打印的消息就是eclipse中打印的消息。也就是错误信息，起初，我觉得idea好不人性，看个错误还要这么费事。然后又看看了，原来错误信息可以在这里看的
