第二部：创建一个实体类
import java.util.Date;
public class MsgPushEntity {
// private Integer mid; //推送信息申请表主键ID
//
// private Integer sellerid;//商户ID
//
// private Integer msgtype;//消息推送类型:1 消息推送 2 发送短信
private String content;//消息推送内容
private Date pushdate;//推送时间
private String pushobj;//全部:0; 高频次:1;中频次:2;低频次:3;一些天未消费:4;高消费:5;中消费:6;低消费:7;其他客户:8(老客户);店铺新客户:9;角色A:10;角色B:11;角色C:12:角色D:13
private Date applytime;//申请时间
private String status;//审核状态:0 待审核 1 审核通过 2 审核不通过
// private String reason;//审核不通过理由
//
// private Date edate;//审核时间
// public Integer getMid() {
// return mid;
// }
// public void setMid(Integer mid) {
// this.mid = mid;
// }
// public Integer getSellerid() {
// return sellerid;
// }
// public void setSellerid(Integer sellerid) {
// this.sellerid = sellerid;
// }
// public Integer getMsgtype() {
// return msgtype;
// }
// public void setMsgtype(Integer msgtype) {
// this.msgtype = msgtype;
// }
public Date getPushdate() {
return pushdate;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
public void setPushdate(Date pushdate) {
this.pushdate = pushdate;
}
public String getPushobj() {
return pushobj;
}
public void setPushobj(String pushobj) {
this.pushobj = pushobj;
}
public Date getApplytime() {
return applytime;
}
public void setApplytime(Date applytime) {
this.applytime = applytime;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
// public String getReason() {
// return reason;
// }
// public void setReason(String reason) {
// this.reason = reason;
// }
// public Date getEdate() {
// return edate;
// }
// public void setEdate(Date edate) {
// this.edate = edate;
// }
第三部：配置mybatis sql文件
<resultMap id="MsgPushEntity" type="com.xmniao.xmn.core.manage.entity.MsgPushEntity" >
<result column="content" property="content" typeHandler="com.xmniao.xmn.core.manage.service.BlobTypeHandle"/>
<result column="push_date" property="pushdate" jdbcType="DATE"/>
<result column="push_object" property="pushobj" jdbcType="VARCHAR"/>
<result column="apply_time" property="applytime" jdbcType="DATE"/>
<result column="status" property="status" jdbcType="VARCHAR"/>
</resultMap>
<select id="queryMsgApplyList" parameterType="map" resultMap="MsgPushEntity">
SELECT content,
date_format(push_date,'%Y-%m-%d %H:%i:%s') pushdate,
push_object pushobj,
date_format(apply_time,'%Y-%m-%d %H:%i:%s') applytime,
case status when 0 then '待审核' when 1 then '已推送' else '已拒绝' end status
from t_msg_push_apply
where sellerid = #{sellerid}
and msg_type = #{msgType}
<if test="status != null">
and `status` != #{status}
</if>
order by mid desc
</select>
第四部：实现类
public Object pushMessageLogs(TypeRequest typeRequest){
try {
Map<Object,Object> paramMap = new HashMap<>();
paramMap.put("sellerid", typeRequest.getSellerid());
paramMap.put("msgType", typeRequest.getType());
List<MsgPushEntity> resultList = pushMessageDao.queryMsgApplyList(paramMap);
List<Map<Object,Object>> pushlist = new ArrayList<Map<Object,Object>>();
MsgPushEntity mpe = new MsgPushEntity();
for(int i=0; i<resultList.size(); i++){
Map<Object,Object> map = new HashMap<Object,Object>();
mpe = resultList.get(i);
String content = mpe.getContent();
map.put("content", content);
map.put("pushtime", mpe.getPushdate());
map.put("pushobject", mpe.getPushobj());
map.put("applytime", mpe.getApplytime());
map.put("pushstatus", mpe.getStatus());
pushlist.add(map);
}
Map<Object, Object> resultResponse = new HashMap<Object, Object>();
resultResponse.put("pushlogs", pushlist);
MapResponse response = new MapResponse(ResponseCode.SUCCESS, "提交成功");
response.setResponse(resultResponse);
return response;
} catch (Exception e) {
e.printStackTrace();
return new BaseResponse(ResponseCode.FAILURE, "获取消息推送历史记录失败");
}
}
