jsp转静态例子

1个Servlet：SetCharacterEncodingFilter.java
 
package com.util;
import java.io.IOException;
import javax.servlet.*;
public class SetCharacterEncodingFilter  implements Filter{
 protected String encoding = null;
 protected FilterConfig filterConfig = null;
 protected boolean ignore = true;
 public void destroy()
 {
    this.encoding = null;
    this.filterConfig = null;
 }
 public void doFilter(ServletRequest request, ServletResponse response,
     FilterChain chain) throws IOException, ServletException
 {
    if (ignore || (request.getCharacterEncoding() == null))
    {
     String encoding = selectEncoding(request);
     if (encoding != null)
      request.setCharacterEncoding(encoding);
    }
    chain.doFilter(request, response);
 }
 public void init(FilterConfig filterConfig) throws ServletException
 {
    this.filterConfig = filterConfig;
    // 获取初始化参数
    this.encoding = filterConfig.getInitParameter("encoding");
    String value = filterConfig.getInitParameter("ignore");
    if (value == null)
    {
     this.ignore = true;
    } else if (value.equalsIgnoreCase("true"))
    {
     this.ignore = true;
    } else if (value.equalsIgnoreCase("yes"))
    {
     this.ignore = true;
    } else
     this.ignore = false;
 }
 protected String selectEncoding(ServletRequest request)
 {
    return (this.encoding);
 }
}
