1.添加删除固定路由规则
添加 route add 15.0.32.0(要去访问的网段) mask 255.255.255.0 -p 15.50.112.93
删除 route delete 15.0.32.0 mask 255.255.255.0 -p 15.50.112.93
查看路由规则
route print
-p含义为永久添加到路由表。-p后面的ip是该网络设置的网关(如15.0.32.0设定的网关是15.50.112.93)。
2.安装多个jdk，但无法生效问题
今天遇到一个特别无语的问题。之前安装了jdk1.7，后面又安装了jdk1.8。环境变量配置的是1.7的路径，结果java -version一直是1.8。
怎么配置都无效，最终解决方式为：将Path变量的 jdk,jre放到system32前面即可。
3.EXCEL拼接字符串
- 选一列作为拼接后的字符串存放地址。
- 该列不能设置为字符串格式。
- 该列的某一行 输入="asd"&A2&","&B2
- 下拉即可自动生成升序拼接。
4.WINDOWS下idea
- 安装idea后，进行注册。需要下载JetbrainsIdesCrack-4.2-release-sha1.jar并放到idea bin目录下。
修改idea.exe.vmoptions idea64.exe.vmoptions文件，在最后追加-javaagent:D:ideaIntelliJ IDEA 2018.1.2inJetbrainsIdesCrack-4.2-release-sha1.jar
即jar所在的目录，之后选择activation code区域填写如下的注册码，注册成功。

- 修改快捷键：从eclipse转过来的可以直接修改为eclipse默认。
file-setting-keymap 搜索basic，修改为指定的提示快捷键。如果有冲突，就将冲突的快捷键改掉。
- 修改类头注释：file->setting->Editor->Filr and Code Templates File选项卡，选中Class。
/**
* @program: ${PROJECT_NAME}
* @description: ${description}
* @author: CHX
* @create: ${DATE} ${TIME}
**/
在live templates里点击加号，添加一个group。再添加一个live template
在abbrevation里填写喜欢的快捷键。如/** 将expandwith改为enter

执行恢复计算器的命令
Get-AppxPackage *calculator* -AllUsers| Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}
如果需要恢复相机命令
Get-AppxPackage *camera* -AllUsers| Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}
