数据库中代表日期的也是：

springboot中日期格式转换问题

但是查询出来的时间是这种形式的：2019-04-29T00:16:00.000+0000

我用的fastjson：

处理日期格式：

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.serializer.SerializeConfig;
import com.alibaba.fastjson.serializer.SimpleDateFormatSerializer;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpOutputMessage;
import org.springframework.http.converter.HttpMessageNotWritableException;

import java.io.IOException;
import java.io.OutputStream;
import java.util.Date;

/**
 * @description:

 * @date: 2019-04-29 13:34
 */
@Configuration
public class FastJsonHttpDateConverter extends FastJsonHttpMessageConverter {
    private static SerializeConfig mapping = new SerializeConfig();
    private static String dateFormat;
    static {
        dateFormat = "yyyy-MM-dd HH:mm:ss";
        mapping.put(Date.class, new SimpleDateFormatSerializer(dateFormat));
    }

    @Override
    protected void writeInternal(Object obj, HttpOutputMessage outputMessage)
            throws IOException, HttpMessageNotWritableException {
        // TODO Auto-generated method stub

        OutputStream out = outputMessage.getBody();
        String text = JSON.toJSONString(obj, mapping, this.getFeatures());
        byte[] bytes = text.getBytes(this.getCharset());
        out.write(bytes);
    }

}

查询后会变成：

yyyy-MM-dd HH:mm:ss这种格式的日期数据 ：2019-04-29 08:16:00
