How to solve the problem of question mark garbled characters when json is transmitted to the front-end using ajax? ajaxjson

Springmvc I use transmits a json file to the front-end at the controller layer. It is okay to display the text in the background. The Chinese text is displayed normally and then to the front-end.

The Chinese character becomes a question mark.

Later found, because the controller returned json with @ ResponseBody, and spring source code in the implementation class @ ResponseBody found that the default encoding is iso-8859-1, and the project is encoded as UTF-8, therefore, garbled characters may occur when the Chinese characters are passed.

Here I use annotations to solve the problem:

@ RequestMapping (value = "/echarts. do", produces = "application/json; charset = UTF-8 ")

This method is applicable to the new spring version. The version of this project:

<Spring. version> 4.1.4.RELEASE </spring. version>

The above is a small series of solutions to the problem of question mark garbled characters when using ajax to transmit json to the front-end Chinese. I hope it will help you.
