springboot + poi word文档导出，Excel文件读取

第一步：加入poi相关的依赖

    compile('org.apache.poi:poi:3.9')
    compile('org.apache.poi:poi-scratchpad:3.9')
    compile('org.apache.poi:poi-ooxml:3.9')  //当excel文档是2007版的需导入此依赖，使用XSSF...

第二步：在resources目录下创建xlsx(xls)和word文件
word模板文件如下

第三步：上代码

package com.hj;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.xssf.usermodel.XSSFCell;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.util.ResourceUtils;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

import java.io.FileInputStream;
import java.io.FileNotFoundException;

@SpringBootApplication
@EnableSwagger2
public class TestApplication {

    private static String fileName="web-info1.xls";
    public static void main(String[] args) throws Exception {
        SpringApplication.run(TestApplication.class, args);
try {
    HSSFWorkbook wb = new HSSFWorkbook(new FileInputStream(ResourceUtils.getFile("classpath:"+fileName)));
    //Excel工作表
    HSSFSheet sheet = wb.getSheetAt(0);

    //表头那一行
    HSSFRow titleRow = sheet.getRow(0);

    //表头那个单元格
    HSSFCell titleCell = titleRow.getCell(0);

    String title = titleCell.getStringCellValue();

    System.out.println("标题是：" + title);
}catch (Exception e){
    XSSFWorkbook wb = new XSSFWorkbook(new FileInputStream(ResourceUtils.getFile("classpath:web-info1.xls")));
    //Excel工作表
    XSSFSheet sheet = wb.getSheetAt(0);

    //表头那一行
    XSSFRow titleRow = sheet.getRow(0);

    //表头那个单元格
    XSSFCell titleCell = titleRow.getCell(0);

    String title = titleCell.getStringCellValue();

    System.out.println("标题是："+title);
}

    }
}
