Answer 1

java.io.FileNotFoundException
文件找不到，打印下文件的路径就明白了

Answer 2

com.disk.action.management.TitleAction.addTitle(TitleAction.java:81)
去TitleAction 81行看看里面那个为空。

Answer 3

TitleAction.addTitle(TitleAction.java:81)看下TitleAction类中的81行是怎么弄的，这里报错是找不到文件。

Answer 4

我很无语！起初我怀疑是相对路径的问题，然后在自己的电脑上启动Tomcat，我和别人都可以访问！而且没有出现问题，测试环境就有问题，我对比了相关联的文件，一摸一样！就是上传不了。。

Answer 5

 String directory = ServletActionContext.getServletContext().getRealPath("/");
看看路径吧。路径问题
