在struts1.2中,往数据库插入数据出现中文乱码

最佳答案那就写个编码过滤器了

package com.util;

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 Encoding implements Filter {
@SuppressWarnings("unused")
private FilterConfig config=null;
String encoding=null;
public void destroy() {
this.encoding=null;
this.config=null;

}

public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
if(encoding!=null)
request.setCharacterEncoding(encoding);
chain.doFilter(request, response);

}

public void init(FilterConfig arg0) throws ServletException {
this.config=arg0;
this.encoding=arg0.getInitParameter("encoding");

}

}
在web.xml写这一段代码
<filter>
<filter-name>encoding</filter-name>
<filter-class>com.util.Encoding</filter-class> <!--这里写你编码类在的位置-->
<init-param>
<param-name>encoding</param-name>
<param-value>GBK</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
如果你用的是mysql，也要设置mysql的编码
