#java 文件下载 报错

本文介绍了一种在Java中处理文件下载过程中出现的IllegalStateException异常的方法。通过在Action类中使用OutputStream并确保输出流正确关闭及刷新，最终通过返回null解决了问题。

文件下载时碰到

ng.IllegalStateException: getOutputStream() has already been called for this

 

我是在java action内用到的OutputStream .

在最后out.closer(); out.flash(); 都用到了还是没解决问题。最后return  null; 就ok 了

在写文件的时候，系统已经调用了getOutputStream()方法；如果接口还返回了其它数据，这样会造成2次调用getOutputStream()，所以报了此错误；在respone中已经调用了getOutputStream()方法。说系统应该调用了多次；所有只要接口不再返回数据的话，系统就不会再报以上错误。（当然不影响业务正常导出）

关于这个错误，网上有很多种说法， 其中下面的说法：执行下载的页面，在Java脚本范围外（即之外），不要包含HTML代码、空格、回车或换行等字符，有的话将不能正确下载。不信的话，可以在上述源码中%>很多人都认可。正确与否，试试便知。测试环境：tomcat5.5.23和6.0.10import="com.jspsmart.upload.*" %>//这里有空格/回车/换行/
