SpringBoot使用fastjson

在其实文件中添加bean

package com.springboot.market; import com.alibaba.fastjson.serializer.SerializerFeature; import com.alibaba.fastjson.support.config.FastJsonConfig; import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.autoconfigure.http.HttpMessageConverters; import org.springframework.context.annotation.Bean; import org.springframework.http.converter.HttpMessageConverter; import java.util.List; @SpringBootApplication public class MarketApplication { @Bean public HttpMessageConverters fastJsonHttpMessageConverters() { // 1.定义一个converters转换消息的对象
        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter(); // 2.添加fastjson的配置信息，好比: 是否须要格式化返回的json数据
        FastJsonConfig fastJsonConfig = new FastJsonConfig(); fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat); // 3.在converter中添加配置信息
 fastConverter.setFastJsonConfig(fastJsonConfig); // 4.将converter赋值给HttpMessageConverter
        HttpMessageConverter<?> converter = fastConverter; // 5.返回HttpMessageConverters对象
        return new HttpMessageConverters(converter); } public static void main(String[] args) { SpringApplication.run(MarketApplication.class, args); } }
