JAVA获取运行程序的src路径
JavaPrj使用: System.getProperty("user.dir")+"\\src"或直接"\\src"
JavaWeb使用Thread.currentThread().getContextClassLoader().getResource("/").getPath()
获取src目录 | JavaWeb | JavaProj |
System.getProperty("user.dir") | D:\tools\MyEclipse2015 | D:\tools\Workspaces\TestJava |
Thread.currentThread() .getContextClassLoader() .getResource("/") .getPath() | /D:/tools/Workspaces /.metadata/.me_tcat7 /webapps/AhExam4SSM /WEB-INF/classes/ | java.lang.NullPointerException |
2018-04-29补充：JavaWeb项目中：
String path = this.getServletContext().getRealPath("/WEB-INF/classes");
System.out.println("path = " + path);
String path2 = Thread.currentThread().getContextClassLoader().getResource("/").getPath();
System.out.println("path2 = " + path2);运行结果：（path2中空格变成%）
path = C:\Users\AndyMi\Workspaces\MyEclipse 2015\.metadata\.me_tcat7\webapps\TestJavaWeb\WEB-INF\classes path2 = /C:/Users/AndyMi/Workspaces/MyEclipse%202015/.metadata/.me_tcat7/webapps/TestJavaWeb/WEB-INF/classes/
