Can you please tell me how to use Spring Javaconfig to directly load/autowire a properties file to a java.util.Properties field?

Thanks!

Later edit - st

Answer 1

declare a PropertiesFactoryBean.

@Bean
public PropertiesFactoryBean mailProperties() {
    PropertiesFactoryBean bean = new PropertiesFactoryBean();
    bean.setLocation(new ClassPathResource("mail.properties"));
    return bean;
}

Legacy code had following config

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