代码实现

ExcelBean

import lombok.Data;
/**  
 * @FileName: ExcelBean  
 * @Description:  从Excel读取数据
 */
@Data  
public class ExcelBean {  
    @ExcelProperty("表名")  
    private String tableName;  
    @ExcelProperty("字段英文名称")  
    private String fieldOfEn;  
    @ExcelProperty("字段中文名称")  
    private String fieldOfCn;  
    @ExcelProperty("字段类型")  
    private String fieldType;  
    @ExcelProperty("类型长度")  
    private String fieldLength;  
}

Test Method

读取excel数据，进行转化写入word

public void test_Lord(){
	String path = "D:\\xuanji_dwd/资产.xlsx";  
	templateParse(path);
}

public void templateParse(String dataStandardExcelPath) {  
    try (FileInputStream fileInputStream = new FileInputStream(dataStandardExcelPath)) {  
        ZipSecureFile.setMinInflateRatio(0.001);  
        List<ExcelBean> fields = EasyExcel.read(fileInputStream, ExcelBean.class, null).doReadAllSync();  
        Map<String, List<ExcelBean>> groupMap = fields.stream().collect(Collectors.groupingBy(ExcelBean::getTableName));  
        List<Map<String,Object>> foreachList = new ArrayList<>();  
        groupMap.forEach((String tableName,List<ExcelBean> beans)->{  
            Map<String,Object> map = new HashMap<>();  
            map.put("tables",beans);  
            map.put("tableName",tableName);  
            foreachList.add(map);  
        });  
  
        Map<String,Object> resMap = new HashMap<>();  
        resMap.put("list",foreachList);  
  
        // 破解循环表格  
        LoopRowTableRenderPolicy policy = new LoopRowTableRenderPolicy();  
        Configure config = Configure.builder()  
                .bind("tables", policy)  
                .build();  
  
        XWPFTemplate.compile(new File("D:\\docx/template.docx"),config).render(resMap).writeAndClose(new FileOutputStream("D:\\docx/output.docx"));  
    } catch (FileNotFoundException e) {  
        e.printStackTrace();  
    } catch (IOException e) {  
        e.printStackTrace();  
    }
