SpringBoot的@RequestBody 注解如何接受非json格式字符串参数？-灵析社区

如果接口注解是@RequestBody ，且修饰的是字符串参数，请求如果接受非json格式字符串参数？ 最近维护公司的一个springboot项目，发现有一个controller接口写的接收参数形式很奇怪。代码如下 @ResponseBody @PostMapping(value = "/SendNews") public String sendContent(HttpServletRequest request,@RequestBody String lstMsgId) { System.out.println(lstMsgId); return lstMsgId; } 我的请求参数是："90c8c36f23a94c1487851129aa47d690/90c8c36f23a94c1487851129aa47d690" 我用postman 请求，在raw里面带上字符串（非Json格式）可以正常请求，而使用hutool工具请求如下代码却不能请求成功。  HttpRequest request = HttpRequest.get(url); request.header("gatewayAuth", "xxxx"); responseJsonStr = request.form(null)//表单内容 .body("90c8c36f23a94c1487851129aa47d690/90c8c36f23a94c1487851129aa47d690") .timeout(50000)//超时，毫秒 .execute().body(); 报如下错误： org.springframework.http.converter.HttpMessageNotReadableException: JSON

String lstMsgId 怎么接收非json格式的字符串参数，求解~
