json输出日期格式，前台接收为时间戳的解决方案

一、场景再现

数据库里面可都是，date格式的数据。使用springBoot 的注解转成json格式到前台就变成这了。。。头疼。

二、解决方案 

import com.alibaba.fastjson.annotation.JSONField;

 

添加上述注解，写上符合自己需求的日期格式

说明：加过上述字段，记得重启项目试试。如果还是不可以。就需要手动增加一下json解析的配置。

三、配置json

import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
import com.querydsl.jpa.impl.JPAQueryFactory;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.web.HttpMessageConverters;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Bean;
import org.springframework.data.jpa.repository.config.EnableJpaAuditing;
import org.springframework.http.MediaType;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.web.client.RestTemplate;
import org.springframework.web.filter.CharacterEncodingFilter;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

import javax.persistence.EntityManager;
import java.util.ArrayList;
import java.util.List;

@SpringBootApplication
public class AppStart {
    @Autowired
    private RestTemplateBuilder builder;

    @Bean
    public RestTemplate restTemplate() {
        return builder.build();
    }

    public static void main(String[] args) {
        SpringApplication.run(AppStart.class, args);
        log.info("SpringBoot start successful!");
    }
    @Bean
    public HttpMessageConverters fastJsonHttpMessageConverters() {
        FastJsonHttpMessageConverter converter = new FastJsonHttpMessageConverter();
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        fastJsonConfig.setSerializerFeatures(SerializerFeature.WriteMapNullValue,
                SerializerFeature.DisableCircularReferenceDetect);
        converter.setFastJsonConfig(fastJsonConfig);
        List<MediaType> fastMediaTypes = new ArrayList<>();
        fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
        converter.setSupportedMediaTypes(fastMediaTypes);
        return new HttpMessageConverters(converter);
    }

    @Bean
    public FilterRegistrationBean filterRegistrationBean() {
        FilterRegistrationBean registrationBean = new FilterRegistrationBean();
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setForceEncoding(true);
        characterEncodingFilter.setEncoding("UTF-8");
        registrationBean.setFilter(characterEncodingFilter);
        return registrationBean;
    }

    @Bean
    public JPAQueryFactory jpaQueryFactory(EntityManager entityManager){
        return new JPAQueryFactory(entityManager);
    }


}

结束。
