problem with a constructor called ./RentABike-context.xml

[juyer]

Could you tell me how to execute a constructor
public ArrayListRentABike(String storeName)
instead of public ArrayListRentABike()

I have a line
<property name="storeName"><value>BruceBikes</value></property>
so why a constructor without parameters is executed?

So <property> tags are to call the setter methods style of Dependency Injection. For constructor, the tag is <constructor-arg>

So, if you want the constructor to be called then use the <constructor-arg> tag instead.

Good Luck

Thank you bytor99999
Amazing, that works

<!-- <property name="storeName"><value>BruceBikes</value></property>
-->

<constructor-arg index="0" type="java.lang.String" value="BruceBikesyeahhhh"/>
