该博客介绍了如何通过添加配置类解决Spring Boot应用中HTTP响应可能出现的乱码问题。主要步骤包括创建自定义的HttpMessageConverter，设置UTF-8字符集，并配置FastJsonHttpMessageConverter以支持UTF-8，确保返回的JSON内容正确显示。

解决办法：添加配置类，改编码为utf-8

具体代码：

import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
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.WebMvcConfigurationSupport;

import java.nio.charset.StandardCharsets;
import java.util.ArrayList;
import java.util.List;

@Configuration
public class CharsetConfig extends WebMvcConfigurationSupport {
    @Bean
    public HttpMessageConverter<String> responseBodyConverter() {
        return new StringHttpMessageConverter(
                StandardCharsets.UTF_8);
    }

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

        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(
                SerializerFeature.PrettyFormat
        );
        List<MediaType> fastMediaTypes = new ArrayList<>();
        fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
        fastConverter.setSupportedMediaTypes(fastMediaTypes);
        fastConverter.setFastJsonConfig(fastJsonConfig);

        converters.add(fastConverter);
    }

    @Override
    public void configureContentNegotiation(
            ContentNegotiationConfigurer configurer) {
        configurer.favorPathExtension(false);
    }
}
