1.在tomcat6/conf/server.xml
    中<Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" URIEncoding="UTF-8"/>
2.在对应的应用中添加字符过滤器
    继承    javax.servlet.Filter

public void doFilter(ServletRequest request, ServletResponse response,
   FilterChain chain) throws IOException, ServletException {
  // TODO Auto-generated method stub

  request.setCharacterEncoding("utf-8");
  chain.doFilter(request, response);
 }

3.在对应的应用中web.xml中添加过滤器
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>cn.ywj.webexample.CharacterEncodingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
