Passing int to spring property

Question

I want to pass int instead of string which is default in spring PropertyPlaceholderConfigurer.

<property name="mailServerPort" value="${mail.port}" />

This give me error because mailServerPort is int type and ${mail.port} is string type.

How can I convert ${mail.port} to int?

Answer 1

According to me the casting should work properly if the value of port is proper integer.

Still if you face the problem you can try SpringExpressionLanguage(SpEL) for conversion.

<property name="mailServerPort" value="#{ T(java.lang.Integer).parseInt(mail.port) }"/>

Hope this helps you.
