项目场景：

controller层接收参数，并把参数组装起来通过服务间的调用传递给服务端

问题描述

controller接收起来没有什么问题，但是调用服务端的时候，问题出现了

原因分析：

代码示例

    @GetMapping(value = "/recommendDoctorByHospitalId")
    public BaseResponse<PageInfo<ResDoctorBaseDTO>> recommendDoctorByHospitalId(@RequestParam("hospitalId") Integer hospitalId) throws BaseException {
        ResSystemConfigDTO systemConfig = sysConfigHandle.getSystemConfig(SysConfigConstant.number_of_hospital_home_page_doctor_recommendations);
        }

    public ResSystemConfigDTO getSystemConfig(String configName) {
        ReqQuerySystemConfigDTO dto = new ReqQuerySystemConfigDTO();
        dto.setConfigName(configName);
        List<ResSystemConfigDTO> infos = sysConfigurationClient.querySysConfiguration(dto).getInfos();
        if (null != infos && infos.size() != 0) return infos.get(0);
        return null;
    }

这样就会出现Unrecognized token ‘hospitalId’: was expecting (‘true’, ‘false’ or ‘null’);这个问题

解决方案：

将controller的@RequestParam替换成@PathVariable就可以

	@GetMapping(value = "/recommendDoctorByHospitalId/{hospitalId}")
    public BaseResponse<PageInfo<ResDoctorBaseDTO>> recommendDoctorByHospitalId(@PathVariable("hospitalId") Integer hospitalId)

是一个强大的工具，但它要求数据必须是合法的 JSON。当你存储的是普通字符串时，强行使用它只会导致反序列化失败。根据实际需求选择合适的序列化器（通常是），是避免此类问题的关键。反斜杠 \是JSON格式要求的转义字符。不会修改你的字符串内容。的行为取决于输入类型：如果是对象 → 序列化为JSON（无外层引号）。如果是字符串 → 当作字符串值处理（有外层引号）。redis-cli显示字符串时都会加引号，这是它的显示约定，不是实际存储内容。不对的地方请大家指正。
前后端数据交互常见问题：JSON parse error: Unrecognized token ‘phoneNum‘
qq_45947664的博客

后端：加上@RequestBody用String接收，后再一一对多参数进行处理，subString（）方法：根据字符的下标位置进行分割，不包前，但包后，eg：第9个字符是“=”，所以从第九个字符开始分割，到第20个字符结束，包括了第二十个。（是对发送过去的数据格式限制），dataType是对接收数据的格式限制。原理不清楚，有大佬的话，求求路过看一眼，顺带告诉我一下，真心感恩~传参结果：正常，第一个手机号，第二个前端MD5加密后的密码。，没有传值的参数，会自动成null。去掉contentType属性。

看错误是json转换异常，实际上是因为redisTemplate在做数据存储的时候会把存储的内容序列化，所以，redisTemplate读取的时候也会把内容反序列化，但是我们直接通过客户端去set数据的时候不会做序列化，但是通过redisTemplate读取的时候依旧会进行反序列化，所以在这个时候就会报反序列化异常。：在客户端中的set用程序的redisTemplate.opsForValue().set。
