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）

 1 @RequestMapping(value = "/getCarList", method = RequestMethod.GET)
 2     public ResultObject getCarByCpName(@RequestParam(value = "cpName",required = true)String cpName,@RequestParam(value = "carNo",required = false)String car_no) {
 3 
 4         char[] isc = cpName.toCharArray();
 5         boolean is = true;
 6         for (char c : isc) {
 7             is = isChinese(c);
 8             if (!is) break;
 9         }
10         //boolean isc = isChinese(cpName.getBytes());
11         if (!is) {
12             try {
13                 cpName = new String(cpName.getBytes("ISO-8859-1"),"UTF-8");
14             } catch (Exception e) {
15                 e.printStackTrace();
16             }
17         }
18         ResultObject rst = commonService.getCarByCpName(cpName, car_no);
19         return  rst;
20     }
21 
22     /**
23      * 判断字符是否是中文
24      *
25      * @param c 字符
26      * @return 是否是中文
27      */
28     public static boolean isChinese(char c) {
29         Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);
30         if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS
31                 || ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS
32                 || ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A
33                 || ub == Character.UnicodeBlock.GENERAL_PUNCTUATION
34                 || ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION
35                 || ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS) {
36             return true;
37         }
38         return false;
39     }

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
