气!!!!!!!!!!!!!!!!!!!!为什么??????????为什么还是乱的!!!!!

我都说了,同样一个JSP页面,用个bean直接连接数据库不会乱,而用了weblogic连接池就乱了...

强烈建议你用过滤器！
一般情况下都可以解决，而且下次就不会遇到这样的乱码问题。
package com.tsinghua.filter;import java.io.IOException;import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;public class EncodingFilter  implements Filter{
    /** 默认的字符编码 */
    protected String encoding = null;
    private FilterConfig config = null;     public void init(FilterConfig config) throws ServletException {
        this.config = config;
        this.encoding = config.getInitParameter("encoding");
    }
    public void doFilter(ServletRequest request, ServletResponse response,
                         FilterChain chain) throws IOException,
        ServletException {
        if (!"ignore".equals(this.encoding)) {
            request.setCharacterEncoding(this.encoding);
        }
        chain.doFilter(request, response);
    }

    public void destroy() {
        config = null;
    }
}web.xml下面：
  <filter>
<filter-name>EncodingFilter</filter-name>
<filter-class>com.tsinghua.filter.EncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>GBK</param-value>
</init-param>
</filter> <filter-mapping>
<filter-name>EncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

还是那句话.....同样一个JSP页面,用个bean直接连接数据库不会乱,而用了weblogic连接池就乱了...

在Tomcat 文件夹下有个过滤器直接拿过来用就行了SetCharacterEncodingFilter，直接去搜下问题就解决啦
乱码问题确实让人烦！

String s=new String("你要处理的中文".getBytes("ISO-8859-1"),"UTF-8")

先看看是不是数据库里就是乱的。要是那里乱码，就是数据库的问题了。先保证数据库撒。如果是jsp导致的乱码就看这里：http://test.family168.com/tutorial/jsp/html/jsp-ch-02.html#jsp-ch-02-02

疯了.........................
在网上搜了好久,能用的方法我都用了..
大家再看看我这个情况,
从request.getParameter("..")过来的String完全能正常显示,就是bean.doSomething()修改数据库内容才乱了,
而且这个问题是在通过weblogic连接池才发生,如果这个bean通过MysqlDriver直接与数据库相连是不发生乱码的.
请看我现在配置:
1.weblogic8.1
jdbc:mysql://localhost:3306/myweb?useUnicode=true&characterEncoding=gb2312
2.
mysql5.0  gb2312
3.
web.xml
<context-param>
    <param-name>weblogic.httpd.inputCharset./*</param-name>
    <param-value>GB2312</param-value>
  </context-param>4.weblogic.xml
<weblogic-web-app>
  <jsp-descriptor>
    <jsp-param>

    </jsp-param>
    <jsp-param>
      <param-name>encoding</param-name>

    </input-charset>
  </charset-params>
  <context-root>MyWebPro</context-root>
</weblogic-web-app>Who can help me?????????????

只能用"疯了"来形容自己,在网站搜了好多,大同小异,能试的我都试了.

只能是weblogic的问题,不是Mysql的问题

顶5楼
数据库字符集、jsp&html设定字符集和保存文件时都用utf-8

算了吧.用UTF-8页面显示都显示不了,直接报错.
weblogic.utils.ParsingException: nested TokenStreamException: antlr.TokenStreamIOException

算了.重装Mysql 就好了..晕了..

调试易
