Lucene使用FSDirectory [英] Lucene using FSDirectory

问题描述

我编写了一个简单的Java程序来创建lucene索引，但是语法出错.

I wrote a simple java program to create a lucene index, but I get an error with the syntax.

我的代码:

static final String INDEX_DIRECTORY = "/home/yuqing/Desktop/index";
Directory index = FSDirectory.open(new File(INDEX_DIRECTORY));

我收到以下错误消息，

open (java.nio.file.path) in FSDirectory cannot be applied to java.io.file

推荐答案

有关路径类的Java教程以获取信息.关于它如何工作的.

The FSDirectory.open call takes a Path argument, not a File (as of Lucene version 5.0). You can check out the Java tutorial on the Path Class for information on how it works.

因此，您的代码应如下所示:

So, your code should look like:

static final String INDEX_DIRECTORY = "/home/yuqing/Desktop/index";
Directory index = FSDirectory.open(Paths.get(INDEX_DIRECTORY));
