JXLS+SpringMVC导出Excel

maven导入jar包

	<!-- springMVC jxls Excel 导出 start-->
       <dependency>
           <groupId>net.sf.jxls</groupId>
           <artifactId>jxls-core</artifactId>
           <version>1.0.6</version>
       </dependency>
       <dependency>
           <groupId>net.sf.jxls</groupId>
           <artifactId>jxls-reader</artifactId>
           <version>1.0.6</version>
       </dependency>
     <!-- springMVC jxls Excel 导出 end-->

新建JxlsExcelUtil.java

package com.htdz.ydkx.export;

import net.sf.jxls.transformer.XLSTransformer;
import org.apache.poi.ss.usermodel.Workbook;
import org.springframework.web.servlet.view.AbstractView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Map;

public class JxlsExcelUtil extends AbstractView {

    private String exportFileName;
    private String templatePath;
    private static final String CONTENT_TYPE="application/vnd.ms-excel";

    /**
     * @param templatePath 模版相对于当前classpath路径
     * @param exportFileName 导出文件名
     */
    public JxlsExcelUtil(String templatePath, String exportFileName) {
        this.templatePath = templatePath;
        this.exportFileName = exportFileName;
        setContentType(CONTENT_TYPE);
    }

    @Override
    protected void renderMergedOutputModel(Map<String, Object> model, HttpServletRequest request, HttpServletResponse response) throws Exception {
        InputStream is = null;
        OutputStream os = null;
        try{
            os = response.getOutputStream();
            response.setContentType(getContentType());

            //解决导出文件名中文乱码问题
            String filename = new String(exportFileName.getBytes("gb2312"),"iso8859-1");
            response.setHeader("content-disposition", "attachment;filename=" + filename + ".xls");

            //获取excel模板
            is = JxlsExcelUtil.class.getClassLoader().getResourceAsStream(templatePath);

            //转换成excel并输出
            XLSTransformer transformer = new XLSTransformer();
            Workbook workbook = transformer.transformXLS(is,model);

            //将内容写入输出流并把缓存的内容全部输出
            workbook.write(os);
            os.flush();
            os.close();
            is.close();

        }catch (Exception e){
            e.printStackTrace();
        }

    }
}

手工创建需要导出的excel模板
Controller中的代码

@RequestMapping(params = "exportCustInfoXls")
   public ModelAndView exportCustInfoXls(HttpServletRequest request,HttpServletResponse response,DataGrid dataGrid){
   	//参数
   	String phone = request.getParameter("phone");
   	//查询数据
   	List<BrandProduct> brandProductList = brandProductInfo.getBrandProduct((dataGrid.getPage()-1)*dataGrid.getRows(),
   			dataGrid.getRows(),phone);
   	ModelMap modelMap = new ModelMap();
   	modelMap.put("brandInfos", brandProductList);
   	return new ModelAndView(new JxlsExcelUtil("jxls/template/brandInfo.xls","客户对应的品牌信息"), modelMap);
   }
