How to get the text content files with tika 1.6?

问题

Hi i try get the text content from any files in this list pdf,txt,doc,docx and odt the implementation with tika previously worked fine but now is broken, The code is it:

```

public void uploadFile(FileUploadEvent event) throws Exception {
 UploadedFile file = event.getUploadedFile();
 byte[] data = file.getData();
 Tika tika = new Tika();
 string = tika.parseToString(new ByteArrayInputStream(data));
 ...
}

```

Any ideas? , bad implementation ?

回答1:

You need to add tika-parsers.

For example with maven add this dependency to your pom.xml:

<dependency>
        <groupId>org.apache.tika</groupId>
        <artifactId>tika-parsers</artifactId>
        <version>1.7</version>
</dependency>

And you can use Auto-Detect Parser:

BodyContentHandler handler = new BodyContentHandler();
AutoDetectParser parser = new AutoDetectParser();
Metadata metadata = new Metadata();
try {
    parser.parse(is, handler, metadata);
    text = handler.toString();
} catch(TikaException te) {
    System.out.println(te.toString());
} finally {
    is.close();
}
