从/xl/worksheets/sheet1.xml part coldfusion poi中删除记录合并单元格

我正在创建一个带有java poi库的excel文件，它被创建但是当我打开文件时，excel会弹出一条消息，说“我们发现文件内容有问题 . 你想让我们尽可能多地恢复如果你相信工作簿的来源 . “

单击是时，它弹出“修复的部分：/xl/worksheets/sheet1.xml部分，带有XML错误 . 加载错误 . 第121行，第0列 . 删除记录：合并来自/xl/worksheets/sheet1.xml部分的单元格” .

并且文件中没有数据丢失，我无法理解excel错误背后的原因 .

我不能在这里写完整个代码，但这里是与xlsx文件相关的主要内容：

<cfdirectory action="list" directory="#expandPath('/poi_39')#" name="poidir"/>
            <cfset paths = arrayNew(1)>
            <cfloop query="poidir">
                <cfset arrayAppend(paths, directory & "\" & name) />
            </cfloop>
            <cfset server.loader = createObject("component", "javaloader.JavaLoader").init(loadPaths=paths, loadColdFusionClassPath=true) />
            <cfscript>
                _Thread = createObject("java", "java.lang.Thread");
                currentClassloader = _Thread.currentThread().getContextClassLoader();
                try {
                    // Set the current thread's context class loader as Javaloader's classloader, so dom4j doesn't die
                    _Thread.currentThread().setContextClassLoader(server.loader.getURLClassLoader());
                    //code found online
                    //inp = createObject("java", "java.io.FileOutputStream").init("#fullpath#");
                    //reseting the value on code
                    inp = 100;
                    //workBook = server.loader.create("org.apache.poi.xssf.usermodel.XSSFWorkbook").Init(inp);
                    workBook = server.loader.create("org.apache.poi.xssf.streaming.SXSSFWorkbook").Init(inp);
                }
                catch(Any exc) {
                    rethrow;
                }
                finally { // We have to reset the classloader, due to thread pooling.
                    _Thread.currentThread().setContextClassLoader(currentClassloader);
                }
            </cfscript>

网上没有任何相关内容，有没有人遇到过这样的问题？如果有，请帮我解决这个问题 . 谢谢
