ExcelWriter excelWriter = EasyExcel.write(response.getOutputStream())
        .inMemory(true)
        // 添加水印处理器
        .registerWriteHandler(new WaterMarkHandler("名字"+ DateTime.now().toString(" yyyy-MM-dd HH:mm") + " 内部资料禁止外传"))
        .build();
//这里 需要指定写用哪个class去写
List list;
WriteSheet writeSheet = EasyExcel.writerSheet(0, "sheet1").head(XXXDTO.class).build();
excelWriter.write(list, writeSheet);
writeSheet = EasyExcel.writerSheet(1, "sheet2").head(XXXDTO.class).build();
excelWriter.write(list, writeSheet);
writeSheet = EasyExcel.writerSheet(2, "sheet3").head(XXXDTO.class).build();
excelWriter.write(list, writeSheet);
//关闭流
excelWriter.finish();

核心是配置:

ExcelWriter excelWriter = EasyExcel.write(response.getOutputStream())
        .inMemory(true)
        // 添加水印处理器
        .registerWriteHandler(new WaterMarkHandler("名字"+ DateTime.now().toString(" yyyy-MM-dd HH:mm") + " 内部资料禁止外传"))
        .build();

java.awt.FontFormatException: bad pfa font

1. 将字体文件放到resources/font/目录下面
   
2. 加载字体资源文件

    src/main/resources
    true
    
        ***.xml
        ***.ttf
    


    src/main/resources
    
    false
    
        **/*.ttf
    

我使用这种方式失败了，但是还是在这里记录下：
