Java 各种路径获取方式整理

System.out.println(directory.getCanonicalPath());//获取标准的路径 System.out.println(directory.getAbsolutePath());//获取绝对路径

//user.dir指定了当前的路径

System.getProperty("user.dir");

//获得Tomcat 安装目

System.getProperty("catalina.home")

//服务器配置目录

System.getProperty("catalina.base")

另外：System.getProperty()中的字符串参数如下：System.getProperty()参数大全# java.version                                Java Runtime Environment version# java.vendor                                Java Runtime Environment vendor# java.vendor.url                           Java vendor URL# java.home                                Java installation directory# java.vm.specification.version   Java Virtual Machine specification version# java.vm.specification.vendor    Java Virtual Machine specification vendor# java.vm.specification.name      Java Virtual Machine specification name# java.vm.version                        Java Virtual Machine implementation version# java.vm.vendor                        Java Virtual Machine implementation vendor# java.vm.name                        Java Virtual Machine implementation name# java.specification.version        Java Runtime Environment specification version# java.specification.vendor         Java Runtime Environment specification vendor# java.specification.name           Java Runtime Environment specification name# java.class.version                    Java class format version number# java.class.path                      Java class path# java.library.path                 List of paths to search when loading libraries# java.io.tmpdir                       Default temp file path# java.compiler                       Name of JIT compiler to use# java.ext.dirs                       Path of extension directory or directories# os.name                              Operating system name# os.arch                                  Operating system architecture# os.version                       Operating system version# file.separator                         File separator ("/" on UNIX)# path.separator                  Path separator (":" on UNIX)# line.separator                       Line separator ("/n" on UNIX)# user.name                        User’s account name# user.home                              User’s home directory# user.dir                               User’s current working directory

//user.dir指定了当前的路径

System.getProperty("user.dir");
