官方推荐，通过实现 org.springframework.web.servlet.config.annotation.WebMvcConfigurer接口，进行相应配置。
-
org.springframework.web.servlet.config.annotation.WebMvcConfigurer#addCorsMappings跨域配置 -
org.springframework.web.servlet.config.annotation.WebMvcConfigurer#configureMessageConverters消息转换器配置

application.yml
yuyanjia:
webmvc:
corss-mapping: /website/**
以上配置能解决Controller返回字符串乱麻问题
拦截器返回乱码可以通过 配置文件进行 配置
application.yml

http:
encoding:
force: true
enabled: true
