Spring Boot uses fastjson to serialize objects

Configured in MonitorApplication.java

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.context.annotation.ComponentScan;
import org.springframework.http.converter.HttpMessageConverter;

@SpringBootApplication
public class MonitorRedbagMqApplication {

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

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

Test Java objects

public class MonitorRedbagDto implements Serializable {
    private static final long serialVersionUID = -1600920246142453543L;

    // 红包ID
    private Integer redbagId;
    // 用户ID
    private Long userId;
    // 发放时间
    @JSONField(format = "yyyy-MM-dd HH:mm:ss")
    private Date sendTime;

    // setter getter方法
}

If you don't use fastjson serialization, return:

{
  "redbagId": null,
  "userId": 16,
  "sendTime": "2018-03-06T12:04:15.483+0000"
}

Serialized with fastjson, returns:

{
  "userId": 16,
  "sendTime": "2018-03-06 12:04:15"
}
