1.获取properties文件:

String path="application.properties"; 1>InputStream in= Thread.currentThread().getContextClassLoader().getResourceAsStream(path);

2>InputStream in = doTest.class.getClassLoader().getResourceAsStream(path);

2.这两种方式都会自动在path前补上classpath的相对路径所以不需要加/

1> URL url = Thread.currentThread().getContextClassLoader().getResource("");

2> URL url = doTest.class.getResource("");

这两个都会获取/的路径

3.以后使用获取properties文件就用:

String path="application.properties";
InputStream in =Thread.currentThread().getContextClassLoader().getResourceAsStream(path);

会自动在前面补上根路径的绝对路径,绝对路径classpath就是指 /
