EXCEL转JAVA BEAN

pom.xml回入以下包:
        <dependency>
            <groupId>net.sf.jxls</groupId>
            <artifactId>jxls-core</artifactId>
        </dependency>
        <dependency>
            <groupId>net.sf.jxls</groupId>

        </dependency>
        <dependency>
            <groupId>net.sf.jxls</groupId>
            <artifactId>jxls-examples</artifactId>
        </dependency>


转换的配置文件:
<workbook>
  <worksheet name="Sheet1">
    <section startRow="0" endRow="0" />
    <loop startRow="1" endRow="1" items="result" var="app" varType="n.app.valueobject.App">
