=========================================================================================

异常原因：webservice传输的数据中，有特殊字符或者乱码！

解决方案：将特殊字符或者乱码过滤掉

public static final String chopWhitespace(String str) {

if(null==str || "".equals(str))return "";

StringBuilder sb = new StringBuilder("");

for (int i = 0; i < str.length(); i++) {

char ch = str.charAt(i);

int ci = ch;

//System.out.println(ch+" "+ci);

if (9 == ci || 10 == ci || 13 == ci || 32 <= ci && !Character.isISOControl(ci)) {

sb.append(ch);

}

}

return sb.toString();

}
