[IvanGan]

有没有哪位大侠遇到过这样的情况啊?

[IvanGan]

??

[popufig]

不支持GBK编码？没碰到过这样的...

[IvanGan]

有谁遇到过吗

[redlaputa]

不支持输出gbk
重装试试

[IvanGan]

问题的原因是在jsp中的"gbk"用了小写,改用大写"GBK"就ok了

[baseuser]

代码发上来。

急的话联系我qq。79993563

[baseuser]

估计你是写了resp.setCharacterencoding("gbk");
换成resp.setContentType("text/html;charset=GBK");
