. */ boolean supports(MethodParameter methodParameter, Type targetType, Class<? afterBodyRead(Object body, HttpInputMessage inputMessage, MethodParameter parameter, Type targetType String> result = new HashMap<>(); result.put("hello", "world"); return result; } 通过下图可以看出 targetType HttpInputMessage beforeBodyRead(HttpInputMessage inputMessage, MethodParameter parameter, Type targetType >> converterType); 在这里 body 其实已经是 @RequestBody 对应的参数即 targetType, 同时还要求你返回 targetType 类型，这时在想做强制转换已经很麻烦了
