Answer 1

过滤器配置  
XML code 
<filter>
    <filter-name>encoding</filter-name>
    <filter-class>
        filter.FilterEncoding
    </filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>gbk</param-value>
    </init-param>
</filter>Java code
package 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 FilterEncoding implements Filter 
{ 
    protected String encoding;          // 接收字符编码
    protected boolean ignore;            // 是否忽略大小写
    protected FilterConfig filterConfig; // 初始化配置    public void init(FilterConfig filterConfig) throws ServletException 
    {
        // 从web.xml文件中读取encoding的值
        encoding = filterConfig.getInitParameter("encoding"); 
        // 从web.xml文件中读取ignore的值
        String value = filterConfig.getInitParameter("ignore"); 
        // 以下三种情况均为忽略大小写
        if(value == null) 
        { 
            ignore = true; 
        }
        else if(value.equalsIgnoreCase("yes")) 
        { 
            ignore = true; 
        } 
        else if(value.equalsIgnoreCase("true")) 
        { 
            ignore = true; 
        } 
    } 
    // doFilter方法
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException 
    {
        if(ignore || request.getCharacterEncoding() == null) 
        {
            // 如果为空先从web.xml中得到
            String encoding = selectEncoding(request); 
            if(encoding != null) 
            {
                // 设置字符集编码
                request.setCharacterEncoding(encoding); 
            }
        }
        // 继续执行
        chain.doFilter(request, response); 
    } 
    // 得到字符编码
    private String selectEncoding(ServletRequest request) 
    { 
        return encoding; 
    } 
    public void destroy() 
    { 
  
    } 
}
如果是url的get提交参数带中文的  
可以改下面这个文件，加入一个URIEncoding="GBK"  
X:\Tomcat 5.5\conf\Server.xml  
   <Connector  
        port="8080"  
        redirectPort="8443"  
        minSpareThreads="25"  
        connectionTimeout="30"  
        maxThreads="150"  
        maxSpareThreads="75"  
URIEncoding="GBK">  HTML code<%@ page contentType="text/html;charset=gbk"%>   //此处的charset的值要和web.xml里的   <param-value> </param-value>值一样

Answer 2

filter解决request response 编码
但是还有起码3处会产生乱码的
分别是
eclipse编辑页面（jsp）也有编码
jsp页面编码
db编码

Answer 3

 
在web.xml中
<!--配置字符文字过滤器 编码位GBK-->
    <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
    <param-name>encoding</param-name>
    <param-value>gbk</param-value>
    </init-param>
    <init-param>
    <param-name>forceEncoding</param-name>
    <param-value>true</param-value>
    </init-param>
    </filter>
   <filter-mapping>
   <filter-name>CharacterEncodingFilter</filter-name>
   <url-pattern>/*</url-pattern>
   </filter-mapping>
