Here’s how you can create a property file which can be injected on Java classes as well as on bean XML configuration file.
Firstly ensure annotation config is switched on:
Create your properties file, in this case I create config.properties on my classpath root (src/main/resources/config.properties on Maven-compliant project)
name=Gerry
Register this property file on your spring context using
Whenever you want to inject the value into a Java class, you can use annotation
public class Person { ("${name}") private String name; //... }
This will only work if your java beans are scanned by the same Spring context. If on different context you will need to create a separate property placeholder
Similarly you can do the same to xml bean config file
Multiple Environment Trick
If the value of your configuration item differ accros multiple environments (JDBC URL and context path are a good example of these), you can use the same method to inject value form environment variable.
