- 关于SSH架构,使用struts2的过滤器Filter和cookie实现自动登录问题
- JAVA文件流输入输出的问题!!
- struts2里面的“根命名空间”和“默认命名空间”有什么区别?
- Struts2 多文件上传
- 关于socket通信慢的问题
- WebLogic8.x中控制台无法登陆
- 求救,第一次用rmi写的第一个程序。
- org.hibernate.exception.GenericJDBCException: could not execute query怎么解决
- 能用过滤器防止未经登陆直接进入系统吗
- 请问哪里有中文版的struts书籍下载,我卖都卖不到
- 高手解决hibernate+spring+ehcache缓存
- 关于web.xml的疑问
但是服务器如果是tomcat5以上 那么这个filter只对post有效 get就要设置服务器的属性
而且并不一定完全好用,那时候就需要用我一开始提到的方式自己来编码解码,百试不爽的
你在web.xml中配置
<filter>
<filter-name>Set Character Encoding</filter-name>
<filter-class>filters.SetCharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>你的编码</param-value>
</init-param>
</filter> <filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
然后 你的页面中使用post的方式提交package filters;
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;
import javax.servlet.UnavailableException;
/**
* <p>Example filter that sets the character encoding to be used in parsing the
* incoming request, either unconditionally or only if the client did not
* specify a character encoding. Configuration of this filter is based on
* the following initialization parameters:</p>
* <ul>
* <li><strong>encoding</strong> - The character encoding to be configured
* for this request, either conditionally or unconditionally based on
* the <code>ignore</code> initialization parameter. This parameter
* is required, so there is no default.</li>
* <li><strong>ignore</strong> - If set to "true", any character encoding
* specified by the client is ignored, and the value returned by the
* <code>selectEncoding()</code> method is set. If set to "false,
* <code>selectEncoding()</code> is called <strong>only</strong> if the
* client has not already specified an encoding. By default, this
* parameter is set to "true".</li>
* </ul>
*
* <p>Although this filter can be used unchanged, it is also easy to
* subclass it and make the <code>selectEncoding()</code> method more
* intelligent about what encoding to choose, based on characteristics of
* the incoming request (such as the values of the <code>Accept-Language</code>
* and <code>User-Agent</code> headers, or a value stashed in the current
* user's session.</p>

你需要自己处理的..
也能接收到,只是自己处理比较麻烦一点..
document.form1.action = "gs_yuangongxinxi.do?method=doAdd&aaa="+aaa;
--------------------------------------------------------------------
是scipt代码吧,应该是var
var aaa="工工工工工工工工";
document.form1.action = "gs_yuangongxinxi.do?method=doAdd&aaa="+aaa;
