ClassLoader Java 获取当前类文件所在的路径详解编程语言

如果类是打包在jar文件里，那这个方法就无能为力，只能想其他辙

ResourcePathTester.java

import java.net.URL; 
 
import org.apache.commons.lang.StringUtils; 
 
/**

public class ResourcePathTester { 
 
    public static void main(String[] args) { 
        System.out.println(getResourcePath()); 
    } 
 
    private static String getResourcePath() { 
        String className = ResourcePathTester.class.getName(); 
        String classNamePath = className.replace(".", "/") + ".class"; 
        URL is = ResourcePathTester.class.getClassLoader().getResource(classNamePath); 
        String path = is.getFile(); 
        path = StringUtils.replace(path, "%20", " "); 
 
        return StringUtils.removeStart(path, "/"); 
    } 
}
