@ResponseBody 返回对象中的Date类型如何格式化格式

 

1.首先定义一个格式化Date 类，这个类要实现JsonSerializer 接口

 

 

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;

/**

 * Date 转为json 格式时格式化时间格式

 * @author dell

 */

 

 

 

public class JsonDateSerializer extends JsonSerializer<Date> {

  private SimpleDateFormat dateFormat=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

  @Override

  public void serialize(Date date, JsonGenerator gen, SerializerProvider provider)

          throws IOException, JsonProcessingException {

      String value = "";

      if(null !=date){

      value = dateFormat.format(date);

      }

      gen.writeString(value);

  }

}

 

 

 

 

 

2. 在需要格式化的get方法上加上， @JsonSerialize(using=JsonDateSerializer.class)

如：

 @JsonSerialize(using=JsonDateSerializer.class)

    public Date getCreatedate() {

        return createdate;

    }

 

    public void setCreatedate(Date createdate) {

        this.createdate = createdate;

    }

 

 

转化前json结果：

{"resData":{"status":"1","message":"成功","data":{

"pickupInfo":{"pid":"104917","orderid":"17021700912600","prono":"17021702","proname":"boce普??2",

"pickupcode":"46W5S1","pickupnumber":1,"status":"2","userid":"1111110978",

"usercode":"123456789012345678","warehouseid":"天津市河东区仓库街道","createdate":1487260800000,

"pickupdate":null,"username":"提货人信??,"userphone":"15902248761","qualitystan":"","ysendtime":"",

"penaltyrate":0,"keepgoods":"","remark":"","istransferfeeconfirmed":"","isbondconfirmed":""}

 

}

 

转化后结果：

{"resData":{"status":"1","message":"成功","data":{

"pickupInfo":{"pid":"104917","orderid":"17021700912600","prono":"17021702","proname":"boce普??2",

"pickupcode":"46W5S1","pickupnumber":1,"status":"2","userid":"1111110978",

"usercode":"123456789012345678","warehouseid":"天津市河东区仓库街道","createdate":2017-02-17 13:58:59,

"pickupdate":null,"username":"提货人信??,"userphone":"15902248761","qualitystan":"","ysendtime":"",

"penaltyrate":0,"keepgoods":"","remark":"","istransferfeeconfirmed":"","isbondconfirmed":""}

}
