<util:properties> equivalent in java based configuration for spring

Question

What would be the equivalent in java based configuration of XML based spring configuration

<util:properties id="mapper"  location="classpath:mapper.properties" /> 

To then be able to use this specific property object in code like :

@Resource(name = "mapper") private Properties myTranslator; 

Looking at the doc, I looked at the

@PropertySource 

annotation but it seems to me that the particular propertyfile will not be able to be accessed individually from the Environment object.

Very simply, declare a PropertiesFactoryBean.

@Bean(name = "mapper") public PropertiesFactoryBean mapper() {     PropertiesFactoryBean bean = new PropertiesFactoryBean();     bean.setLocation(new ClassPathResource("com/foo/jdbc-production.properties"));     return bean; } 

In the documentation here, you'll notice that before they made <util:properties>, they used to use a PropertiesFactoryBean as such

<!-- creates a java.util.Properties instance with values loaded from the supplied location --> <bean id="jdbcConfiguration" class="org.springframework.beans.factory.config.PropertiesFactoryBean">   <property name="location" value="classpath:com/foo/jdbc-production.properties"/> </bean> 

Converting that to Java config is super easy as shown above.
