I have encountered this problem many times. The json string returned to the front end under springMVC is always garbled in Chinese. Every time I have to go through the previous code to see the solution, it is necessary to make a note to write down this problem.
Solution:
Add the following to the method annotation:
@RequestMapping(value = "/auditingSelector", produces = "application/json;charset=UTF-8")
Where application/json means return json format
text/html means to return a string or web page content.
After adding this, there should be basically no garbled problem, which is based on the premise of configuring encoding filtering.
