Unable to make batch insert into Oracle DB using MyBatis

Question

I try to make batch insert into table at Oracle database using MyBatis (integrated with Spring) .

It is a definition of method in mapper interface:

public void savePayments(@Param("payments") List<MassPaymentItem> payments);

It is a MyBatis XML mapper code:

<insert id="savePayments" parameterType="MassPaymentFileItem" useGeneratedKeys="false">
    INSERT INTO mass_payments
        (payment_id, file_id, msisdn, amount, status)
    <foreach collection="payments" item="payment" index="index" separator=" UNION ALL ">
        SELECT SEQ_MASS_PAYMENT.nextval, #{payment.fileId}, #{payment.msisdn}, #{payment.amount}, 0 FROM DUAL
    </foreach>
</insert>

When I execute this I receive MyBatisSystemException with message "nested exception is org.apache.ibatis.builder.BuilderException: Improper inline parameter map format. Should be: #{propName,attr1=val1,attr2=val2}"

What is wrong? How to fix it?

I found solution here

<insert id="savePayments">
   INSERT ALL
   <foreach collection="payments" item="payment">
   INTO
      mass_payments_t (payment_id, file_id, msisdn, amount)
   VALUES
      (seq_mass_payment.nextval, #{payment.fileId, javaType=Integer, jdbcType=NUMERIC}, #{payment.msisdn, javaType=String, jdbcType=VARCHAR}, #{payment.amount, javaType=BigDecimal, jdbcType=NUMERIC})
   </foreach>
   SELECT * FROM dual
</insert>
