控制层request和response输入输出中文乱码问题

 

    输入乱码：处理get请求乱码，因为tomcat默认get都是iso-8859-1

 

public class EncodingUtil {

	/**
	 * iso-8859-1转UTF-8
	 * @param s
	 * @return
	 */
	public static String isoToUTF8(String s){
		return toUTF8(s, "ISO-8859-1");
	}
	public static String toUTF8(String s,String enc){
		if (s==null) {
			return null;
		}
		Charset charset = Charset.forName(enc);
		CharsetEncoder ce = charset.newEncoder();
		if (ce.canEncode(s)) {
			try {
				String t = new String(s.getBytes(enc),"UTF-8");
				return t;
			} catch (UnsupportedEncodingException e) {
				e.printStackTrace();
				return s;
			}
		}else{
			return s;
		}
	}
	public static void main(String[] args) {
		System.out.println(toUTF8("æ²¹", "iso-8859-1"));
	}
}

 

 

   输出乱码：json输出浏览器端乱码

 

response.setContentType("text/html;charset=UTF-8");
