急java中用XWPFParagraph来写内容到word怎么设置行间距啊？比如设置为1.5倍行间距

paragraphsetSpacingBetween(18, LineSpacingRuleEXACT);
这里面的18指的是磅值，必须是正整数，LineSpacingRuleEXACT指的是指定值
LineSpacingRule这个枚举类还有两个枚举值，AUTO和AT_LEAST 其中AUTO表示自动（就是单倍行距）AT_LEAST就是最小值，可以通过自定义添加其他规则（我不会）
如果想省事儿，就直接使用paragraphsetSpacingLineRule(LineSpacingRuleAUTO);
不使用第一行提供的方法即可，我也是刚接触不久，希望能帮到你

NPOI 20就可以了。
引用using NPOIXWPFUserModel;
XWPFDocument doc = new XWPFDocument();
docCreateParagraph();
FileStream sw = FileOpenWrite("blankdocx");
docWrite(sw);
swClose();
追加一句，刚才是生成了一个文件，再用流的方式，提示客户端下载，即可
/// <summary>
/// d出提示框，提示用户是否下载保存到本地\
/// </summary>
/// <param name="strFileName">文件路径</param>
public static string openWindowExport(string strFileName)
{
string strReutrn = "";
try
{
FileInfo DownloadFile = new FileInfo(strFileName);
SystemWeb>写
public static void main(String args[])
throws Exception
{
