Lucene 使用 FSDirectory

我编写了一个简单的 java 程序来创建一个 lucene 索引，但是我得到了一个语法错误.

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，

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

推荐答案

FSDirectory.open 调用采用 Path 参数，而不是 文件(从 Lucene 5.0 版开始).您可以查看 Java 路径类教程了解信息关于它是如何工作的.

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));
