java 项目得到jar和classes路径 

 

    public static String getJarPath(Class clazz) {        String path = clazz.getProtectionDomain().getCodeSource().getLocation().getFile();        try {            path = java.net.URLDecoder.decode(path, "UTF-8");            java.io.File jarFile = new java.io.File(path);            return java.net.URLDecoder.decode(jarFile.getParentFile().getAbsolutePath(), "UTF-8");        } catch (java.io.UnsupportedEncodingException e) {            e.printStackTrace();        }        return null;    }    public static String getClassesPath(Class clazz) {        String path = clazz.getClassLoader().getResource("").getPath();        try {            return java.net.URLDecoder.decode(path, "UTF-8");        } catch (java.io.UnsupportedEncodingException e) {            e.printStackTrace();        }        return null;    }

比如在AppTest.java中,

        String path = getClassesPath(AppTest.class);
        print(path);

显示为:

        /C:/workspace1/yourproject/target/test-classes/
