what is the xml mapping for json like this? - mybatis

Question

Tables:
Create table development(
developmentName varchar(100) primary key,
description varchar(100)
);
Create table Student(
name varchar(100) primary key,
dateType varchar(100),
developmentName foreign key reference development(developmentName)
);
Input Json:
The json would come in the format
{ "DevelopmentName":"comp", "description":"Descrizione Tracciatro 1", "Student":[ {
"name":"String",
"dateType":"String",
"DevelopmentName":"comp"
},
{
"name":"String",
"date_type":"String"
"DevelopmentName":"comp"
}]}
DevelopmentName is primary key and which is foreign key for Student.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="it.eng.billing.mapper.Development">
<resultMap id="BaseResultMap" type="it.eng.billing.model.Development">
<result column="DevelopmentName" jdbcType="VARCHAR" property="DevelopmentName" />
<result column="description" jdbcType="VARCHAR" property="description" />
</resultMap>
<insert id="insert" parameterType="it.eng.billing.model.Development" >
insert into Development (DevelopmentName, description) values (#{DevelopmentName,jdbcType=VARCHAR},#{description,jdbcType=VARCHAR})
</insert>
<insert id="insertOptions" parameterType="it.eng.billing.model.Student">
INSERT INTO Student (name,DevelopmentName, datatype)
VALUES
<foreach collection="list" item="option" open="(" separator="),(" close=")" >
#{option.name},#{option.DevelopmentName},#{option.datatype}
</foreach>
</insert>
</mapper>
There is problem with the XML. The json is not getting saved into database.
public interface DevelopmentMapper{
default void save(DevelopmentDto record) {
insert(record);
insertOptions(record.getStudent());
}
from service class, calling developmentMapper.save(DevelopmentDto obj)
