获取javaweb文件路径

1.java工具类中获取resources下面的文件夹下面的文件路径。例如resources/img/logo.png。

1	SendMailUtil.class.getClassLoader().getResource("img/logo.png").getPath()

输出结果：/D:/gitLocalRepo/innerManage/fmInnerManage/out/production/resources/img/logo.png

2.获取java工具类中classpath（class文件的路径）。

System.out.println(Class.class.getClass().getResource("/img/logo.png").getPath());
System.out.println(Thread.currentThread().getContextClassLoader().getResource("img/logo.png"));
System.out.println(SendMailUtil.class.getClassLoader().getResource("img/logo.png"));
System.out.println(ClassLoader.getSystemResource(""));
System.out.println(SendMailUtil.class.getResource(""));
System.out.println(SendMailUtil.class.getResource("/"));

/D:/gitLocalRepo/innerManage/fmInnerManage/out/production/resources/img/logo.png
file:/D:/gitLocalRepo/innerManage/fmInnerManage/out/production/resources/img/logo.png
