方法一 :

import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;

import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;

/**
 * @author zhijian 在屬性或者get方法上加入@JsonSerialize(using=DateFormatSerializer.class)

 */

public class DateFormatSerializer extends JsonSerializer<Date> {

    @Override
    public void serialize(Date value, JsonGenerator gen, SerializerProvider serializers)
            throws IOException, JsonProcessingException {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String datestr = sdf.format(value);
        gen.writeString(datestr);
    }

}
 

方法二 :

// 在屬性或者get方法上加此註解
@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone="GMT+8")
private Date createtime;
