今天完成的事情：

用以接收web数据的bean类

package com.bean;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.stereotype.Repository;

import java.util.Date;

/**
 * @author Arike
 * Create_at 2017/12/14 13:25
 */
@Data
@AllArgsConstructor
@NoArgsConstructor
@Repository
public class StudentGet {
    //该类用于与web页面交互
    private String name;
    private String QQ;
    private String major;
    @DateTimeFormat(pattern = "yyyy-MM-dd")
    private Date entry_time;
    private String gra_school;
    private String online_id;
    private String daily_link;
    private String desire;
    private String bro;
    private String know_from;
}

数据库交互类

package com.bean;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.stereotype.Repository;

/**
 * @author Arike
 * Create_at 2017/12/14 10:36
 */
@Data
@AllArgsConstructor
@NoArgsConstructor
@Repository
public class Student {
    //该类用于与数据库交互
    private Long id ;
    private Long create_at;
    private Long update_at;
    private String name;
    private String QQ;
    private String major;
    private Long entry_time;
    private String gra_school;
    private String online_id;
    private String daily_link;
    private String desire;
    private String bro;
    private String know_from;
    }

date时间转换long格式处理工具类

package com.util;

import com.bean.Student;
import com.bean.StudentGet;

/**

 */
public class ChangeUtil {
    private ChangeUtil(){}
    public static Student change(StudentGet sg){
        Student s = new Student();
        s.setBro(sg.getBro());
        s.setDaily_link(sg.getDaily_link());
        s.setDesire(sg.getDesire());
        s.setQQ(sg.getQQ());
        s.setMajor(sg.getMajor());
        s.setGra_school(sg.getGra_school());
        s.setOnline_id(sg.getOnline_id());
        s.setKnow_from(sg.getKnow_from());
        Long time = sg.getEntry_time().getTime()/1000;
        s.setEntry_time(time);
        s.setName(sg.getName());
        return s;
    }
}

明天计划的事情：

带娃!!! 

遇到的问题：null

收获:意识到了配置文件的重要性.
