jsp页面里传过去一个值例如:<html:link page="/XmList.do?xmLx=基建项目库">,在控制台输出request编码是gb2312,但是得到的值还是乱码,为什么?

大家帮帮忙,小弟谢过了~~~很郁闷~

是不是还应该设置它
response.setContentType("text/html; charset=gb2312");

据觉得这个参数的数据不是用post方式发出去的，对他的字符转换他会和html页面的字符统一！
试试先

[AHUA1001]

这个问题过去好像有人问过，你去MSDN的精华区看看，应该能找到。

[599899]

我把tomcat 的URI Encoding改成gb2312了，这样，bean里得到的确实是中文了。

但是问题又出现了：jsp页面里的“上页、下一页”的链接，其中参数xmLx乱码了，这个参数是是从pageform这个formbean里得到的，（pageform里的xmLx这个参数是中文），jsp页面我已经设置request.setCharacterEncoding("gb2312");，可为什么还是乱码呢？

[追求自由]

真长呀

[599899]

简短点说就是:
jsp页面里传过去一个值例如:<html:link page="/XmList.do?xmLx=基建项目库">,在action类里，得到的xmLx这个值是"??????"乱码,我用了filter在控制台输出request编码也是gb2312,但是得到的值还是乱码,为什么?并没有转化!

[tyong]

试试这个
xmLx= new String(xmLx.getBytes("ISO8859_1"), "GBK");

[tyong]

其中
String xmLx=(String)(request.getParameter("xmLx"));

[599899]

恩，这个好使,我以前就试过，但是,我的filter为什么不好使呢,我看乱码这方面帖子，不是说一个filter就全解决了吗?各位大哥，帮帮忙

[599899]

我试过了，通过表单形式传过去的值都能被filter正确的转化，但是为什么，以**do?xmLx=“基建项目”这种url类型传过去的值就不行呢？

[gong1]

那你看一下你的ie是什么编码格式。^_^

[gong1]

改成自动选择
简体中文。^_^

[cold_blooded]

:<html:link page="/XmList.do?xmLx=基建项目库">,

中的汉字写在java代码里,
或使用 标签的属性,
pararmId,
paramName等.

[dafei0320]

xmLx= new String(xmLx.getBytes("ISO8859_1"), "GBK");
这个应该没有问题！
