JSP中post和get乱码解决方法

GET乱码解决：

tomcat下的server.xml 加入URIEncoding="GBK"

<Connector port="8089" protocol="HTTP/1.1" 
               maxThreads="150" connectionTimeout="20000" 
               redirectPort="8443" URIEncoding="GBK" />

POST乱码解决：

web.xml配置过滤器
   <filter>
    <filter-name>Encoding</filter-name>
    <filter-class>m.Encoding</filter-class>
    <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>

Encoding.java

public class Encoding implements Filter {
    protected FilterConfig filterconfig;
    private String targetEncoding = "GBK";

    public void init(FilterConfig config) throws ServletException {
        this.filterconfig = config;
        String target= config.getInitParameter("encoding");
        if(target!=null){
        targetEncoding = target;
        }
    }

    public void doFilter(ServletRequest srequest, ServletResponse sresponse,
            FilterChain chain) throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest)srequest;
        request.setCharacterEncoding(targetEncoding);
        chain.doFilter(srequest,sresponse);
        
    }

    public void destroy() {
        this.filterconfig = null;
    }

}
