Json信息转换配置_jsonconverterconfig-优快云博客

本文档展示了如何在SpringBoot项目中引入FastJson依赖，并配置为默认的HttpMessageConverter，设置日期格式化、Json美化及处理空值策略，以优化JSON序列化过程。

Json信息转换配置类的编写

- - 1.引入fastJson依赖
  - 2.编写

1.引入fastJson依赖

<dependency>
	 <groupId>com.alibaba</groupId>
	 <artifactId>fastjson</artifactId>
	 <version>1.2.78</version>
</dependency>

2.编写

@Configuration
public class JsonHttpMessageConverterConfig {
    @Bean
    @Primary    //优先级
    public HttpMessageConverters fastJsonHttpMessageConverters(){
        FastJsonHttpMessageConverter messageConverter = new FastJsonHttpMessageConverter();
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setDateFormat("yyyy-MM-dd hh:mm:ss");//日期转换格式
        fastJsonConfig.setSerializerFeatures(
                SerializerFeature.PrettyFormat,//优美Json格式
                SerializerFeature.WriteNullStringAsEmpty,//如果字符串为空，显示null
                SerializerFeature.WriteNullListAsEmpty,//同理，集合
                SerializerFeature.WriteMapNullValue,
                SerializerFeature.MapSortField,//map键排序
                SerializerFeature.DisableCircularReferenceDetect//禁用循环引用
        );
        messageConverter.setFastJsonConfig(fastJsonConfig);
        return new HttpMessageConverters(messageConverter);
    }
}
