读取word内容：
view plaincopy to clipboardprint
package poi.doc;

/**
* 利用POI实现从word中读取内容
*/
import java.io.FileInputStream;

public class DOCReader {

public static String fileToRead = "c:/test.doc";

public static void main(String[] args) throws Exception{
// 创建输入流读取DOC文件
FileInputStream in = new FileInputStream(fileToRead);
