Insert/update into multiple rows (collections) in table MyBatis

Method 1 (only for insert) : 
To add multiple record into "product" table

The XML file is as follows
<insert id="insertList" parameterType="HashMap" useGeneratedKeys="true">
INSERT INTO product (vendor_id, name ,description)
VALUES
<foreach collection="paramList" item="param" separator=",">
(#{param.vendorId}, #{param.name}, #{param.description})
</foreach>
</insert>


The invoking Java code is as follows

List products = new ArrayList();
HashMap<String, Object>  para = new HashMap<String, Object>();

Product product1 = new Product("vendor_id1,"pen","good pen");
Proudct product2 = new Product("vendor_id1,"book","good book");

products.add(product1);
products.add(product2);

para.put ("paramList",products);
Integer status = mapper.insertList(para);


Method 2: (work both for insert and update)

You also can use ExecutorType.BATCH  session in MyBatis to do batch insert and update

//batch session
session = sessionFactory.openSession(ExecutorType.BATCH, false);
