求助，ssm框架insert语句接收不到pojo类的数据什么问题

Question

这是前端输入的数据

前端AJAX传入数据

后台Controller层代码

service层

sql输出语句表示这两层都能接受数据

但是插入语句找不到数据

==>  Preparing: insert into staff(id,sname,sex,birthday,sid,depart_id,post_id,entrydate,joinworkdate,workform, ,staffsource,politicalstatus,nation,nativeplace,stel,semail,sheight,bloodtype,maritalstatus, registeredresidence,education,degree,university,major,graduationdate,startdate,enddate,status,peroidopdate) values (null, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?,?,? ,'正常' ,?) 

下面是Dao层代码

@Repository("staffDao")
@Mapper
public interface StaffDao {

    public int addStaff(Staff staff);
}

mybatis-conf.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
     <mappers>
        <mapper resource="com/mybatis/AdminMapper.xml"/>
        <mapper resource="com/mybatis/DepartmentMapper.xml"/>
        <mapper resource="com/mybatis/PostMapper.xml"/>
        <mapper resource="com/mybatis/StaffMapper.xml"/>
    </mappers>
</configuration>

StaffMapper.xml代码如下

数据库结构

Staff类

public class Staff {
    private Integer id;
    private String sname;
    private String sex;
    private Date birthday;
    private String birthday1;
    private String sid;
    private Integer depart_id;
    private Integer post_id;
    private Date entrydate;

    //get和set省略
}

感谢各位，解决了，实体类中少了一个字段
