import javax.servlet.Filter;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;

public class CharEncodingFilter implements Filter {

private String charSet ;

public void init(FilterConfig parm1) throws ServletException {
charSet = parm1.getInitParameter("charset") ;
if (charSet == null && charSet.length() < 1)
{
charSet = "UTF-8" ;
}
System.out.println ("CharEncodingFilter--字符集: " + this.getCharSet()) ;
}


public void doFilter(ServletRequest parm1, ServletResponse parm2,
FilterChain parm3) throws IOException, ServletException {

// 设定字符集
parm1.setCharacterEncoding(this.getCharSet());
parm3.doFilter(parm1, parm2);
//页面中每个向服务器的请求都被过滤 -- 如 图片,js,HTML/JSP等等
//System.out.println ("---CharEncodingFilter: " + this.getCharSet()) ;
}

public void destroy() {
// TODO: Add your code here
this.setCharSet(null) ;
}


public void setCharSet(String charSet) {
this.charSet = charSet;
