上周完成的工作以及本周计划-2

public class EncodingFilter implements Filter {
protected String encoding = null;

protected FilterConfig filterConfig = null;

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

public void doFilter(ServletRequest request, ServletResponse response,
		FilterChain chain) throws IOException, ServletException {
	// Select and set (if needed) the character encoding to be used
	String encoding = selectEncoding(request);
	if (encoding != null) {
		request.setCharacterEncoding(encoding);
		response.setCharacterEncoding(encoding);
	}
	// Pass control on to the next filter
	chain.doFilter(request, response);
}

public void init(FilterConfig filterConfig) throws ServletException {
	this.filterConfig = filterConfig;
	this.encoding = filterConfig.getInitParameter("encoding");
}

protected String selectEncoding(ServletRequest request) {
	return (this.encoding);
}

}

完善EncodingFilter代码
下周继续完善代码
