问题：
.HttpMessageNotReadableException: JSON parse error: Cannot deserialize value of type `java.lang.String` from Array value (token `JsonToken.START_ARRAY`); nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize value of type `java.lang.String` from Array value (token `JsonToken.START_ARRAY`)<EOL> at [Source: (org.springframework.util.StreamUtils$NonClosingInputStream); line: 1, column: 258] (through reference chain: com.xinzhi.pojo.Userinfo["address"])]
前端复选框内地址为数组，后端无法接收。

解决：
先将数组转换为-分割的字符串，构造一个包含多个对象的数组，构造一个对象：将表单内所有的字段放入对象内。将构造好的留言对象添加到数组中：allMessages.push(message);
2. 后端
解决：将后端改为List接收。
Controller层：
/** * 注册接口 * @param userinfo 实体类（注册参数） * @return 状态 */ @CrossOrigin @PostMapping(value = "/enroll") public Result enroll(@RequestBody List<Userinfo> userinfo){ for (Userinfo userinfoList : userinfo) { System.out.println(userinfoList); } return userinfoLoginService.enroll(userinfo); }
ServiceImpl层：
/** * 注册 * * @param userinfo 实体类（注册参数） * @return Result方法（前端接收类型） */ @Override public Result enroll(List<Userinfo> userinfo) { for (Userinfo userinfoList : userinfo) { // 先判断用户名（账户） // 接收类型为布尔值，true判断成功 false判断失败 if (!validateAccount(userinfoList.getUsername())){ System.out.println(userinfoList.getUsername()); return Result.error("用户名格式错误，重新输入。格式为6~20位账号，必须包含数字、字母、下划线中的两种以上。"); } // 判断用户名是否已被注册 // 根据账户名查询数据库内是否已经存在该账户信息 // 进行判断，如果存在，则需让用户重新输入账户名，不存在，进行运行 if (iUserinfoMapper.selectAll(userinfoList.getUsername()) != null) return Result.error("用户名已存在，请重新输入。格式为6~20位账号，必须包含数字、字母、下划线中的两种以上。"); // 判断密码 if (!validatePassword(userinfoList.getPassword())) return Result.error("密码格式错误，重新输入。格式为8~20位字符，至少包含一个数字，大写、小写字母，特殊字符的三种及以上。"); // 使用MD5进行加密密码,并将加密的密码重新赋予实体类中进行对数据库的添加 userinfoList.setPassword(MD5Utils.encrypt(userinfoList.getPassword())); // 判断申请人 if (!validateChineseName(userinfoList.getApplicant())) return Result.error("申请人格式错误，重新输入。格式为中国姓名。"); // 判断申请人性别 if (!validateChineseGender(userinfoList.getGender())){ System.out.println(userinfoList.getGender()); return Result.error("申请人性别不是男或女，重新输入。格式为只能为男或者女。"); } // 判断身份证号码 if (!validateChineseID(userinfoList.getIdentification())){ System.out.println(userinfoList.getIdentification()); return Result.error("身份证号码格式错误，重新输入。格式为中国大陆的身份证号。"); } // 判断证件类型(暂时只支持 身份证 ) if (!validateDocuments(userinfoList.getDocuments())){ return Result.error("证件类型错误，目前仅支持居民身份证哦，请选择身份证。"); } String code = (String) redisTemplate.opsForValue().get("邮箱" + userinfoList.getEmail()); // 判断 用户输入的邮箱验证码 和 发送的验证码是否相同 /*if (!Objects.equals(userinfo.getCode(), code)) return Result.error("验证码输入错误，请重新输入。");*/ // 判断手机号 if (!validatePhoneNumber(userinfoList.getPhone())) return Result.error("手机号格式错误，重新输入。格式为中国大陆的手机号。"); // 将判断完成的数据进行添加 // 接收返回类型，如果为true则注册成功，反之失败 if (iUserinfoMapper.insertEnroll(userinfoList)) { return Result.ok("注册成功"); } else { return Result.error("注册失败"); } } return Result.ok("注册完成！");
