我正面临BOLDWEIGHT_BOLD无法解决或不是字段，并且SOLID_FOREGROUND无法解决或不是字段的问题。

我浏览并找到了2个解决方案，如下所示 headerFont1.setBold（true）; headerStyle1.setFillPattern（FillPatternType.SOLID_FOREGROUND）;

现在尝试执行时，我遇到了空指针异常。
我正在使用apache poi 4.1.1和apache poi-ooxml 4.1.1
有人可以帮我吗？
答案 0 :(得分：0)
尽管这是一个古老的问题，OP可能已经解决了它，但它首先出现在google搜索同一问题中，我想添加我的解决方案以防它对任何人有帮助。
对于poi 4.1.7，我使用font.setBold( true )代替了 font.setBoldweight( Font.BOLDWEIGHT_BOLD )
要将其置于帖子的问题范围内，作者可以更改其代码
发件人：
headerFont2.setBoldweight(Font.BOLDWEIGHT_BOLD);
收件人：
headerFont.font.setBold( true );
鉴于他们还导入了Font类：
import org.apache.poi.ss.usermodel.Font;
