Garbled characters appear in the SpringBoot interface call

package com.cxjg.mvc.util;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.StringHttpMessageConverter;
import org.springframework.web.servlet.config.annotation.ContentNegotiationConfigurer;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

import java.nio.charset.Charset;
import java.util.List;

@Configuration
public class CustomMVCConfiguration extends WebMvcConfigurerAdapter {

    @Bean
    public HttpMessageConverter<String> responseBodyConverter() {
        StringHttpMessageConverter converter = new StringHttpMessageConverter(
                Charset.forName("UTF-8"));
        return converter;
    }

    @Override
    public void configureMessageConverters(
            List<HttpMessageConverter<?>> converters) {
        super.configureMessageConverters(converters);
        converters.add(responseBodyConverter());
    }

application.properties add properties

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

or choose one of these two

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

The springboot interface mainly adds this produces = "application/json;charset=utf-8"

  @PostMapping(value = UrlConstant.FIl_ies, produces = "application/json;charset=utf-8")
