不同的系统下，路径不同，关于路径的研究

String tomcatPath = System.getProperty("user.dir"); out.print("tomcatPath:" + tomcatPath + "<br>"); String filepath = ""; if (tomcatPath.contains("//")) { filepath = tomcatPath.replace("//bin", "//webapps//CDNManageSystem//") + "speed.txt"; } else { filepath = tomcatPath.replace("/bin", "/webapps/CDNManageSystem/") + "speed.txt"; } URL url = Path.class.getClassLoader().getResource("/a.properties"); String path = URLDecoder.decode(url.getPath(), "utf-8"); out.print("path:" + path + "<br>"); out.print("filepath:" + filepath + "<br>"); 

如上代码两个linux下结果：

tomcatPath:/home/app_admin/apache-tomcat-6.0.18/logs
path:/home/app_admin/apache-tomcat-6.0.18/webapps/pathtest/WEB-INF/classes/a.properties
filepath:/home/app_admin/apache-tomcat-6.0.18/logsspeed.txt

 

 

tomcatPath:/home/liuhy/apache-tomcat-6.0.29/bin
path:/home/liuhy/apache-tomcat-6.0.29/webapps/pathtest/WEB-INF/classes/a.properties
filepath:/home/liuhy/apache-tomcat-6.0.29/webapps/CDNManageSystem/speed.txt

 

 

windows下的结果：

tomcatPath:C:/Tomcat6.0/bin
path:/C:/Tomcat6.0/webapps/pathtest/WEB-INF/classes/a.properties
filepath:C:/Tomcat6.0/webapps/CDNManageSystem/speed.txt

 

总结下：

user.dir获得的路径：在哪执行的java命令，就是哪。可是第一个系统怎么会在logs下？？？？

下面两个在bin目录下很正常。在logs下，这就有点说不过去了

如果从java类中获得path还是用getResource比较靠谱
