This will produce invalid JSON, so Hymanson isn't going to help you do that. Assuming that you have no reverse solidus in the member names, you can just do it after outputting the actual string value:
这将产生无效的 JSON，因此 Hymanson 不会帮助您做到这一点。假设成员名称中没有反向实线，则可以在输出实际字符串值后执行此操作：
String invalid = mapper.writeValueAsString(object).replace("\", "\\");
