图片文件读取报错！！

文件number.doc原数据

代码如下：
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import org.apache.poi.hwpf.extractor.WordExtractor;

public class Test {
public String readWord(String path) {
String buffer = "";

try {
if (path.endsWith(".doc")) {
InputStream is = new FileInputStream(new File(path));
WordExtractor ex = new WordExtractor(is);
buffer = ex.getText();
ex.close();
} else {
System.out.println("请选择后缀为.doc的文件");
}

} catch (Exception e) {
e.printStackTrace();
}
return buffer;
}
public static void main(String[] args) {
Test tp = new Test();
String content = tp.readWord("D:\number.doc"); //文件存放的地址
System.out.println("content===="+content);
}
}

myeclipse编译时信息
org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML. You are calling the part of POI that deals with OLE2 Office Documents. You need to call a different part of POI to process this data (eg XSSF instead of HSSF)

content====

有知道原因的吗？

用的api不对，错误信息里面已经告诉你了 （XSSF instead of HSSF），新版的office格式xlsx，需要新的那套api

不同版本excel对应POI版不同，原因和解决办法参考这篇文章：POI - 读取Excel2003、Excel2007或更高级的兼容性问题

import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import org.apache.poi.hwpf.extractor.WordExtractor;

public class Test {
public String readWord(String path) {
String buffer = "";

try {
if (path.endsWith(".doc")) {
InputStream is = new FileInputStream(new File(path));
WordExtractor ex = new WordExtractor(is);
buffer = ex.getText();
ex.close();
} else {
System.out.println("请选择后缀为.doc的文件");
}

} catch (Exception e) {
e.printStackTrace();
}
return buffer;
}
public static void main(String[] args) {
Test tp = new Test();
String content = tp.readWord("D:\Program Files\Java\number.doc"); //文件存放的地址
System.out.println("content===="+content);
}
}
编译没问题，运行出现下列问题
