Using property placeholder location

Question

I have database.properties file with some properties defined. And also application-context.xml file where I'm trying to put these values to databaseRepository bean properties:

    <context:property-placeholder location="file:property_placeholder/database.properties"/>
<bean id="databaseRepository" class="property_placeholder.DatabaseRepository">
    <property name="host" value="${host}"/>
    <property name="port" value="${port}"/>
    <property name="user" value="${user}"/>
    <property name="password" value="${password}"/>
</bean>

but when I'm trying to run app and read database.properties file I get the following errors:

Exception in thread "main" org.springframework.beans.factory.BeanInitializationException: Could not load properties; nested exception is java.io.FileNotFoundException: property_placeholder\database.properties (The system cannot find the path specified)

Here's how files structure looks like: structure

What I'm doing wrong here?

Answer 1

The error is actually FileNotFoundException: property_placeholder\\database.properties , so makes sure that you provide the correct path to your properties file.

Here a correct path could be classpath:property_placeholder/database.properties according to your structure.

You need to put your file database.properties under resources/property_placeholder

Answer 2

use this config in your application context file : put your properties file in resources .

<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>classpath:database.properties</value>
</property>
</bean>
