java 操作 poi 解析、读取 Excel 文件

读取Excel 我这里是用的POI 的jar包

dom4j-1.6.1.jar         poi-3.10.1-20140818.jar        poi-excelant-3.10.1-20140818.jar    xmlbeans-2.6.0.jar

poi-ooxml-3.10.1-20140818.jar       poi-ooxml-schemas-3.10.1-20140818.jar       poi-scratchpad-3.10.1-20140818.jar

以下是maven地址：

<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>3.10.1</version> 
</dependency>

<groupId>org.apache.poi</groupId>

啥也不说了。。。 直接上代码
