Is it possible to do something like this :
<property name="template" value="file:/some/resource/path/myTemplate.txt" />
via annotations without creating custom annotation and populate the field via reflection ? It cannot be done with @Value, cause it works only with Strings...
If not, what is the best way to process Spring bean custom annotations and init the bean accordingly ?

There are several ways to configure beans in a Spring container. Firstly, we can declare them using XML configuration. We can also declare beans using the @Bean annotation in a configuration class. Finally, we can mark the class with one of the annotations from the org.springframework.stereotype package, and leave the rest to component scanning. 2.
In this article, we will discuss Spring Java configuration based @Bean annotation with examples. We will also discuss different scenarios of how and when to use @Bean annotation. @Bean is a method-level annotation and a direct analog of the XML element <bean />.
By default, the bean instances of this class have the same name as the class name with a lowercase initial. In addition, we can specify a different name using the optional value argument of this annotation. Since @Repository, @Service, @Configuration, and @Controller are all meta-annotations of @Component, they share the same bean naming behavior.
To declare a bean, simply annotate a method with the @Bean annotation. You use this method to register a bean definition within an ApplicationContext of the type specified as the method’s return value. By default, the bean name will be the same as the method name . The preceding configuration is exactly equivalent to the following Spring XML:
Use a Resource as the field.
@Value("file:/some/resource/path/myTemplate.txt")
Resource template;
You can use classpath: style URIs this way too.
Then if you need to get a File, use template.getFile()
