java写文件乱码
StringBuffer sb = new StringBuffer();
sb.append("<table border=\"0\" width=\"100%\" cellpadding=\"0\" cellspacing=\"1\" bgcolor=\"b5d6e6\"");
sb.append("<tr>");
sb.append("<td bgcolor=\"#FFFFFE\" height=\"42\" colspan=\""+ (jsd.size()+1) +"\" align=\"center\"><b>" + dataSet.getTitle() + "</b></td>");
sb.append("</tr>");
sb.append("</tr>");
sb.append("</table>");
return sb.toString();
解决方法
使用
public static String ISOToInnerCode(String str) {
if (str == null)
return null;
try {
str = (new String(str.getBytes("ISO-8859-1"), "UTF-8")).trim();
} catch (Exception ex) {
}
return str;
}
若是在servlet中则使用
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=utf-8");
PrintWrite out=response.getWrite();
如果是
OutputStream out = response.getOutputStream();
输出时用out.write(Content.getBytes("utf-8"));即增加一种编码 utf-8也可改成其他编码gbk,gb2312等 依自己情况而定
如果接受传参数时乱码 只需把 response.setContentType("text/html;charset=utf-8");
改成response.setCharacterEncoding("UTF-8");
