Multiple properties file in spring

Question

I load a properties file in spring :

 <context:property-placeholder location="classpath:foo.properties"/>

But if I try to load another file in a different context file I get error.

Answer 1

According to the sources you must provide comma separated list of propery files resources. This should work for you:

<context:property-placeholder location="classpath:foo1.properties,classpath:foo2.properties"/> 

Answer 2

if you need to override properties you can do:

<context:property-override location="classpath:override.properties"/>

if the error is due to not finding a certain property, you can set ignoreUnresolvablePlaceholders to true.

if the error is about not found resource ( and you're ok with it ), you can set ignoreResourceNotFound to true.

OR

if there are errors in finding system properties:

The PropertyPlaceholderConfigurer not only looks for properties in the Properties file you specify. By default it also checks against the Java System properties if it cannot find a property in the specified properties files. You can customize this behavior by setting the systemPropertiesMode property of the configurer with one of the following three supported integer values:

never (0): Never check system properties

fallback (1): Check system properties if not resolvable in the specified properties files. This is the default.

override (2): Check system properties first, before trying the specified properties files. This allows system properties to override any other property source.
