How can I pass multiple parameters and use them?

Question

Hi I\'m new to myBatis.

I\'m using MyBatis and Spring with mybatis-spring.

How can I pass two different types of objects as parameters, and how can I use their p

Answer 1

I would suggest reading the MyBatis documentation - it is pretty comprehensive and accurate.

Lets take an example: updating a customer's name from a com.mycompany.Customer POJO instance, which has a getFirstName() getter.

1. Pass an instance of your Customer class as the parameter
2. Set the parameterType= "com.mycompany.Customer". But check out the alias facility - then you can use the shorthand version parameterType="Customer"
3. Use the standard MyBatis syntax in the SQL: ... set FIRST_NAME = #{firstName}

(Edit) If you need to pass multiple objects there are various options:

1. Pass a map containing the multiple objects
2. Create a utility class the aggregates your multiple classes, and pass this as the parameter.

Again, please read the manual...
