FastJson中文乱码

初学springboot使用fastJson替换默认的jackson后出现中文乱码

解决方式1:

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

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
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;

@SpringBootApplication  // 继承 WebMvcConfigurerAdapter   用于将fastjson替换原有的jackson
public class MainApplication extends WebMvcConfigurerAdapter  {
    // 配置fastJson  用于替代jackson
    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        super.configureMessageConverters(converters);
        //定义一个convert 转换消息的对象
        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
        // 2 添加fastjson 的配置信息 比如 是否要格式化 返回的json数据
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(
                SerializerFeature.PrettyFormat
        );
        fastConverter.setFastJsonConfig(fastJsonConfig);
        // 解决乱码的问题
        List<MediaType> fastMediaTypes = new ArrayList<>();
        fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
        fastConverter.setSupportedMediaTypes(fastMediaTypes);
        converters.add(fastConverter);
    }

   public static void main( String[] args )   {
        SpringApplication.run(MainApplication.class, args);
   }
}


  

解决方式2:

在controller 的方法中 地址映射加入指定编码格式 这个时候也中文不乱码了
@RequestMapping(value = "/", produces = "application/json; charset=utf-8")
