有時候進行引數提交時需要提交很多的引數，一個個引數寫太麻煩，則可以利用POST即兩者的註解直接實體類進行提交，他們會自動進行欄位的對映，相當於json資料格式提交，可以省很多事，但是需要注意欄位為日期Date型別時的處理。

演示程式碼：

springboot controller類：

@RequestMapping("addNewConference/")
    public BaseResult<Conference> addNewConference(@RequestBody Conference conference) {
        System.out.println(conference);
        // 如果id不存在，則新增
 

        if (conference.getConferenceId() == null) {
            conference.setReleaseTime(new Date());
            conference.setStatus(Conference.STATUS_SOON);
            if (conferenceService.insert(conference)) {
                ConferencePushUtils.PushConference(conference);//推送會議
                return
 
 ResultUtils.getSuccBaseResult(conference);
            } else {
                return ResultUtils.getErrorBaseResult(3, "會議釋出失敗");
            }
        }
        // 否則更新
        conferenceService.updateById(conference);
        return ResultUtils.getSuccBaseResult(conference);
    }

Retrofit介面：

//釋出會議
 

    @POST("/conference/addNewConference/")
    Call<BaseResult> sendNewMeeting(@Body Conference conference);

Retrofit 例項化：

Gson gson=new GsonBuilder().setDateFormat("yyyy-MM-dd HH:mm:ss").create();
        Retrofit retrofit = new Retrofit.Builder().client(client).baseUrl(Api.BASE_URL)
                .addConverterFactory(GsonConverterFactory.create(gson)).build();

Conference 實體類 —–關鍵在於給date日期加上格式化format

package com.glut.meetingsign.model;

import com.baomidou.mybatisplus.enums.IdType;
import com.fasterxml.jackson.annotation.JsonFormat;

public class Conference extends Model<Conference> {

    public final static int STATUS_SOON=1;//即將開始
    public final static int STATUS_CANCLE=2;//已取消
    public final static int STATUS_END=3;//已結束

    private static final long serialVersionUID = 1L;

    public Integer getConferenceId() {

    }

    }

    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    public Date getConferenceTime() {
        return conferenceTime;
    }

    public void setConferenceTime(Date conferenceTime) {
        this.conferenceTime = conferenceTime;
    }

    public Integer getStatus() {
        return status;
    }

    public void setStatus(Integer status) {
        this.status = status;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public Date getReleaseTime() {
        return releaseTime;
    }

    public void setReleaseTime(Date releaseTime) {
        this.releaseTime = releaseTime;
    }

    public Integer getUserId() {
        return userId;
    }

    public void setUserId(Integer userId) {
        this.userId = userId;
    }

    public static final String CONFERENCEID = "conferenceId";

    public static final String TITLE = "title";

    public static final String CONTENT = "content";

    public static final String CONFERENCETIME = "conferenceTime";

    public static final String STATUS = "status";

    public static final String ADDRESS = "address";

    public static final String RELEASETIME = "releaseTime";

    public static final String USERID = "userId";

    @Override
    protected Serializable pkVal() {
        return this.conferenceId;
    }

    @Override
    public String toString() {
        return "Conference [conferenceId=" + conferenceId + ", title=" + title + ", content=" + content
                + ", conferenceTime=" + conferenceTime + ", status=" + status + ", address=" + address
                + ", releaseTime=" + releaseTime + ", userId=" + userId + "]";
    }

}

關鍵點：對實體類的Date日期型別欄位進行格式化操作，且保證兩者的格式化格式一致
