Spring configuration setup

[elias chin]

Hello there !
I've been reading https://www.baeldung.com/project-configuration-with-spring and I came across this

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xmlns:context="http://www.springframework.org/schema/context"   xsi:schemaLocation="http://www.springframework.org/schema/beans      http://www.springframework.org/schema/beans/spring-beans-4.0.xsd      http://www.springframework.org/schema/context      http://www.springframework.org/schema/context/spring-context-4.0.xsd">      <context:property-placeholder         location="         classpath*:*persistence-${envTarget}.properties" /> </beans>
I understand that 'envTarget' holds the type of deployment environment. But what does this part exactly do:
<context:property-placeholder         location="         classpath*:*persistence-${envTarget}.properties" />

Hi Elias,

<context:property-placeholder
            location="
            classpath*:*persistence-${envTarget}.properties" />

This part says the container will look for a file persistence-${envTarget}.properties on the classpath of the project.
