我有一条路径(例如:"C:/Users/aaa/bbb/ccc/"
),我的目标是获取父路径(即"C:/Users/aaa/bbb/"
)
为此,我尝试使用java.nio.file.Paths
(在Java中工作),然后尝试将其转换为nashorn js:
import java.nio.file.Paths;
public class ReadPropertiesFile {
public static void main(String[] args) {
String myPath = "C:/Users/aaa/bbb/ccc/";
System.out.println(Paths.get(myPath).getParent());
}
}
Nashorn脚本:
var testPath = "C:/Users/aaa/bbb/ccc/";
var Paths = java.import("java.nio.file.Paths");
try{
var test = Paths.get(testPath).getParent();
console.log("++++++MyFINALPATH+++++"+test);
}catch (e){ console.log("++++++MyFINALPATH+++++"+e);
}
预期输出:C:/Users/aaa/bbb/
错误- TypeError:Paths.get(...)。getParent不是函数
答案 0 :(得分:0)
您需要改用它:
var Paths = Java.type("java.nio.file.Paths");
