我一直在尝试直接打印两个jasper报告，但它只打印一个报告，而另一个报告则发送错误说， net.sf.jasperreports.engine.JRException：java.io.FileNotFoundException：Reports \ Invoice.jasper
以下代码是我用于此操作的IReport连接代码。
IReport showme = new IReport("Reports/Invoice.jasper", param);
IReport showme2 = new IReport("Reports/Bill.jasper", param,"text");最后我在另一个班级中调用了这个
class User(models.Model):
user_id = models.CharField(max_length=40,unique=True)
user_name = models.CharField(max_length=40)

videos_watched = models.ManyToManyField('VideoData', through='WatchedVideo')
