How to set tomcat settings in java config?

Question

Spring

Good afternoon, It is
necessary to organize the correct acceptance of GET request parameters, where Cyrillic can be.
A Spring service that implements RestController.
Method with given signature

@GetMapping(value = "/getDivisionByUniversity",consumes = "application/json;charset=UTF-8")
  public String getDivisionByUniversity(@RequestParam(defaultValue = "%") String university)

application.properties contains the following lines

#Charset of HTTP requests and responses. Added to the "Content-Type" header if not set explicitly.
spring.http.encoding.charset=UTF-8
# Enable http encoding support.
spring.http.encoding.enabled=true
# Force the encoding to the configured charset on HTTP requests and responses.
spring.http.encoding.force=true
server.tomcat.uri-encoding=UTF-8

Google indicates, for example, the following:

Question:
1) Did I correctly set the settings of tomcat itself in application.properties or did I miss something when transferring the configuration?
2) How to pick up the encoding filter if the entire configuration is in java style? There is a filter class, but where to hook it?
3) What else is possibly missed by me when setting up Cyrillic support on tomcat?
