工具类，方法

一：

public class ChinaEncode {
 /**
  * @Description:中文编码异常转换
  * @return String
  */
 public static String encoding(String str){
  String result = null;
  try {
   result = new String(str.getBytes("iso-8859-1"),"utf-8");
  } catch (UnsupportedEncodingException e) {
   // TODO Auto-generated catch block
   new RuntimeException("编码转换失败");
  }
  return result;
 }
//或者
public static String encoding(String str){
     java.net.URLEncoder.encode(str,"UTF-8");
}

二：
String[] stringArray = org.springframework.util.StringUtils.delimitedListToStringArray((String) arguments,",");
