java utf-8_java如何把string转为utf-8
展开全部
java不同编码之间进行转换，都需要使用unicode作为中转。
String str = "任意字符串";
str = new String(str.getBytes("gbk"),"utf-8");

str.getBytes("UTF-8"); 意思是以UTF-8的编码取得字节
new String(XXX,"UTF-8"); 意思是以UTF-8的编码生成字符串
举例：
public static String getUTF8XMLString(String xml) {
// A StringBuffer Object
StringBuffer sb = new StringBuffer();
sb.append(xml);
String xmString = "";
String xmlUTF8="";
try {
xmString = new String(sb.toString().getBytes("UTF-8"));
xmlUTF8 = URLEncoder.encode(xmString, "UTF-8");
