path-variables

问题 I am working on some legacy code running Spring 2.5. I need to use something similar to Spring 3's @PathVariable...anything similar available in Spring 2.5? 回答1: The closest you'll probably get is through ant-style wildcards in mapping paths. You will then have to parse the path manually in your method to get the variable value, I guess. 来源： https://stackoverflow.com/questions/7850286/pathvariable-equivalent-for-spring-2-5

问题 I was earlier running my project using Java 1.7 but now I have to upgrade it to version 1.8. I have it installed as an alternative installation on my CentOS.

问题 I have the bcp tool, it came pre-built with the boost installer. I'd like to extract the dependencies I need from boost into a smaller file, since I'd like to be able to build this project at school. I'm trying to use bcp, but I don't understand how to use it, despite these instructions: http://www.boost.org/doc/libs/1_52_0/tools/bcp/doc/html/index.html#bcp.syntax I've tried typing: bcp boost/thread.hpp /"E:\documents\Dropbox\School\Comp 445\Comp445_Assign2_v2\boost2" from the command prompt,

问题 This question asks how to setup your path variable in Windows to include the Java bin directory allowing you to use the javac command from the prompt. The solution posted to this question states you should hard code the absolute path of the latest Java installation. In this case it happens to be c:\program files\java\jdk1.6.0_16\bin I believe once Java update 17, 18 and beyond are installed your javac cmd will still be using this older version, correct? Am I missing something?? Is there a way

问题 My path looks like this: The top (selected) path contains pandoc.exe and the third from the top (anaconda3) contains pandoc.exe. So the top folder should take priority. If I launch PowerShell simply by launching "Windows PowerShell.exe", and type gcm pandoc I get the top PATH for pandoc.exe: If I launch PowerShell by shift-right-clicking in explorer and selecting "Open PowerShell window here", and type gcm pandoc.exe , I get the Anaconda PATH for pandoc.exe: What gives? Why does it matter in

问题 I have to get params from URL using @PathValiable in SpringBoot application. These params often have slashes . I don't have a control about what a user would enter in URL so I would like to get what he has entered and then I can handle with it. I have already looked through materials and answers here, I don't think that for me the good solution is to ask users somehow encode the entering params. The SpringBoot code is simple: @RequestMapping("/modules/{moduleName}") @ResponseBody public

问题 After I npm installed Sails.js on Windows Server 2008, "sails" command is not recognized. Can someone give me a hint on what values to use in the PATH variable?
