Accesing Property files in Spring - spring

Question

I am new to spring and I am trying to read the values from properties file.
This is my Security XML:-
<beans:bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<beans:property name="location">
<beans:value>AuthProvider.properties</beans:value>
</beans:property>
</beans:bean>
and I am trying to access the properties in java class as follows but its returning nothing:
Properties props = PropertiesLoaderUtils.loadAllProperties("AuthProvider.properties");
PropertyPlaceholderConfigurer props2 = new PropertyPlaceholderConfigurer();
props2.setProperties(props);
for(String key : props.stringPropertyNames())
{
String value = props.getProperty(key);
System.out.println(key + " => " + value);
}
Can someone please tell me where I am goin wrong?

Answer 1

First of all you should show the error you get.
From other side to understand more it is better to read books and docs about a framework.
Regarding Spring you can find enough info here: https://spring.io/guides
Right now it isn't clear what is your general task.
To have just properties as bean it is enough to use:
<util:properties id="myProps" location="AuthProvider.properties"/>
However you shouldn't forget that there is need to correctly specify the location for your file: is it on classpath, on file system, some external URL etc. Here is more info: http://docs.spring.io/spring/docs/current/spring-framework-reference/html/resources.html
At the same reference you can find out how to configure <property-placeholder> and why it is needed.
UPDATE
Just to load properties from file to the Properties object you do it correctly using PropertiesLoaderUtils.loadAllProperties. But here the resourceName should be correct relative path to the file within CLASSPATH - and it will be loaded as resource by ClassLoader.
What is bad here, we don't know where is your AuthProvider.properties, and it says that you provide for it the wrong path.
