传统方式

在application.properties中添加

spring.http.encoding.force=true
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
server.tomcat.uri-encoding=UTF-8

但是，经过测试加上这个依然解决不了乱码问题。

解决方式一

直接在每个Mapping上添加 produces = "application/json;charset=utf-8"

@GetMapping(value = "/api/v1/getRecords", produces = "application/json;charset=utf-8")

虽然这样也能解决中文乱码问题，但是却不是那么优雅而且工作量多且重复
