This article mainly introduces the solution to the problem of Chinese question marks and garbled characters when using ajax to transfer json to the front desk. Friends who need it can refer to it
I use Springmvc to transmit a json to the front desk and backend in the controller layer. There is no problem with the display. Chinese characters are displayed normally but when I reach the front desk,
Chinese characters become question marks.
Later I discovered that because @ResponseBody was used to return json in the controller, and the implementation class of @ResponseBody in the spring source code found that its default encoding was iso-8859-1, and the encoding used by the project was utf-8 , so there will be garbled characters when transmitting Chinese.
Here I used annotations to solve the problem:
@RequestMapping(value="/echarts.do", produces = "application/json; charset=utf-8")
This method is more suitable for the new version of spring, the version of this project:
<spring.version>4.1.4.RELEASE</spring.version>
The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
