Jsp和Servlet如何使用中文参数

首先在java中添加如下类：

package com.filter;//包名

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 EncodeFilter implements Filter{

public void destroy() {
// TODO Auto-generated method stub

}

public void doFilter(ServletRequest req, ServletResponse res, FilterChain c) throws IOException, ServletException {
// TODO Auto-generated method stub
req.setCharacterEncoding("utf-8");
res.setCharacterEncoding("utf-8");
res.setContentType("text/html;charset=utf-8");
c.doFilter(req, res);

}

public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub

}

}

然后再在web.xml中添加一下内容：

<filter>
<filter-name>encodeFilter</filter-name>
<filter-class>com.filter.EncodeFilter</filter-class> <!--这里写你自己的这个类的路径-->
</filter>

<filter-mapping>
<filter-name>encodeFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
