Apache POI 3.17读取PowerPoint文件PPT

网上搜索到的POI读取ppt方法在最新jar包上大都已过时，这里用当前最新的jar包方法读取ppt

POI 操作office需要的jar包：

commons-collections4-4.1.jar
poi-3.17.jar
poi-ooxml-3.17.jar
poi-ooxml-schemas-3.17.jar
poi-scratchpad-3.17.jar
xmlbeans-2.6.0.jar

获取文件后缀名需引入

commons-io-2.4.jar

/**
	 * 读取PowerPoint文件
	 * @param filePath 文档路径
	 * @return
	 */
	public static String readPowerPoint(String filePath){
		File file = new File(filePath);
		//获得文件名  
        String fileName = org.apache.commons.io.FilenameUtils.getExtension(filePath);

    	InputStream is = null;

测试一下

public static void main(String[] args) {
	System.out.println(POI.readPowerPoint("c://1.ppt"));
	System.out.println(POI.readPowerPoint("c://1.pptx"));
	
}
