Spring boot集成jxls实现导入功能

首先上添加maven依赖：

		<!-- jxsl dependency for poi -->
		<dependency>
			<groupId>org.jxls</groupId>
			<artifactId>jxls-poi</artifactId>
			<version>${jxsl.poi.version}</version>
		</dependency>
		<dependency>
			<groupId>org.jxls</groupId>
			<artifactId>jxls</artifactId>
			<version>${jxls.version}</version>
		</dependency>
		<dependency>
			<groupId>org.jxls</groupId>
			<artifactId>jxls-reader</artifactId>
			<version>2.0.3</version>
		</dependency>

导入识别excel转实体的xml文件：

<?xml version="1.0" encoding="UTF-8"?>  
<workbook>  
    <worksheet name="产品列表">  
        <section startRow="1" endRow="1" />  
        <loop startRow="2" endRow="2" items="items" var="item" varType="com.ismartgo.uqcode.model.UqcProduct">  
            <section startRow="2" endRow="2">  
                <mapping row="2" col="0">item.product69code</mapping>  
                <mapping row="2" col="1">item.productName</mapping> 
                <mapping row="2" col="2">item.brand</mapping>  
                <mapping row="2" col="3">item.subBrand</mapping>  
                <mapping row="2" col="4">item.series</mapping>  
                <mapping row="2" col="5">item.category</mapping>   
                <mapping row="2" col="6">item.specs</mapping>  
                <mapping row="2" col="7">item.standardPrice</mapping>  
            </section>  
            <loopbreakcondition>  
                <rowcheck offset="0">  
                    <cellcheck offset="0"></cellcheck>  
                </rowcheck>  
            </loopbreakcondition>  
        </loop>  
    </worksheet>  
</workbook>   

Excel模板：

Xml文件的<worksheet name="产品列表">  代表识别的表格名称

excel转实体类的代码：
