中文乱码之springboot框架中两工程之间参数传递乱码

springboot的分布式开发中，偶尔会遇到中文参数传递乱码的问题，并且当前遇到的是只有某一台电脑上才出现该情况，为此在接受参数的工程接口处添加了一个判断是否中文，如果否则做转换（前提是这个参数必须只能是中文）

@RequestMapping(value = "/getCarList", method = RequestMethod.GET)
    public ResultObject getCarByCpName(@RequestParam(value = "cpName",required = true)String cpName,@RequestParam(value = "carNo",required = false)String car_no) {

        char[] isc = cpName.toCharArray();
        boolean is = true;
        for (char c : isc) {
            is = isChinese(c);
            if (!is) break;
        }
        //boolean isc = isChinese(cpName.getBytes());
        if (!is) {
            try {
                cpName = new String(cpName.getBytes("ISO-8859-1"),"UTF-8");
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        ResultObject rst = commonService.getCarByCpName(cpName, car_no);
        return  rst;
    }

    /**
     * 判断字符是否是中文
     *
     * @param c 字符
     * @return 是否是中文
     */
    public static boolean isChinese(char c) {
        Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);
        if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS
                || ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS
                || ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A
                || ub == Character.UnicodeBlock.GENERAL_PUNCTUATION
                || ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION
                || ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS) {
            return true;
        }
        return false;
    }

如上所示，因为参数设置了必须有，所以没做空判断，首先将字符串转换为char数组，然后循环检测所有字符，如果不是中文则将原字符串做转换
