Springboot使用FastJson后，接口返回中文乱码的问题解决

import java.util.ArrayList;
import java.util.List;

import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;

@Configuration
public class WebConfig extends WebMvcConfigurerAdapter{

	@Override
	public void configureMessageConverters(List> converters) {
		super.configureMessageConverters(converters);
		
		FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
		FastJsonConfig fastJsonConfig = new FastJsonConfig();
		fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
		//处理中文乱码问题
		List fastMediaTypes = new ArrayList();
		fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
		fastConverter.setSupportedMediaTypes(fastMediaTypes);
		converters.add(fastConverter);
	}

}

注意MediaType引用的jar包
