我在使用过程中出现 小的文件可以下载 但是超过15M的就报错 ERROR com.jeecms.download.action.front.DownloadIndeAct - org.apache.catalina.connector.ClientAbortException         at org.apache.catalina.connector.OutputBuffer.realWriteBytes(OutputBuffe r.java:358) [catalina.jar:na] ..........................  楼主务必抽空看看啊

您是哪个版本的?

老版本 2.42

老版本2.4.2

默认是8M，在WEB-INF\classes\struts.properties里修改下
struts.multipart.maxSize=8388608

上传 我知道是8M 但是我下载的时候 超过15M的文件 或者是大点的文件 我上传上去没错 但是下载会报错

修改下下载限制就可以了呀

噢 这个即是 上传也是下载么 struts.multipart.maxSize？

您试试把这个改大。

不行啊 改到500M了 还是不行 一点下载就报错 。整个报错内容是这样的：
