For now I have found following solution: I have added CharacterEscapes to the JsonFactory of the ObjectMapper class. Also I have changed way of writting JSON into response. Instead of
现在我找到了以下解决方案：我已将 CharacterEscapes 添加到 ObjectMapper 类的 JsonFactory。我也改变了将 JSON 写入响应的方式。代替
objectMapper.writeValue(response.getWriter(), myObject)
I'm doing this:
我这样做：
PrintWriter writer = response.getWriter();
writer.print(String.valueOf(objectMapper.writeValueAsBytes(myObject));
writer.flush();
And it works as I wanted.
它可以按我的意愿工作。

I would suggest to use either of below.
我建议使用以下任何一种。
1.You can use GSON library for this purpose.
1.您可以为此使用 GSON 库。
Gson gson = new GsonBuilder().disableHtmlEscaping().create();
2.Use Apache commons StringEscapeUtils.escapeHtml("JSON string").
2.使用Apache公地StringEscapeUtils.escapeHtml("JSON string")。
