TAG:JAVA相关
因为jsp使用的是iso-8859-1编码方式,害苦了亚洲语系的程序员了,关于java编码问题可以做一个专题来写。 jsp和数据库之间都可能出现问题 比如mysql中 应该修改my.ini中的default-character-set 为gbk, 另外在程序里 from里和from外也有不同的编码错误的可能性 以下为一个解决jsp中文编码的类,可以解决这个问题 public class SetCharEncode 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 { String encoding = selectEncoding(request); request.setCharacterEncoding(encoding); response.setContentType("text/html;charset="+encoding); chain.doFilter(request, response); } public void init(FilterConfig filterConfig) throws ServletException { this.filterConfig = filterConfig; 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); } } 在web.xml配置:
setchar com.xdg.filter.SetCharEncode
encoding UTF-8
setchar /*
