package org.zln.springbootfastjson.web.config;

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

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

//        訊息轉換物件
        FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter();
//        配置
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
//        格式化輸出
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        fastJsonHttpMessageConverter.setFastJsonConfig(fastJsonConfig);
//        新增訊息轉化配置
        converters.add(fastJsonHttpMessageConverter);
    }
}

複製程式碼

但是不推薦這麼做

1、fastjson的速度沒有比jackson快很多
2、jackson功能更加強大

    @Bean
    public HttpMessageConverters fastJsonHttpMessageConverters(){
        FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter();
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        fastJsonHttpMessageConverter.setFastJsonConfig(fastJsonConfig);
        
        HttpMessageConverter<?> converter = fastJsonHttpMessageConverter;
        return new HttpMessageConverters(converter);
        
        
    }
