Use properties file in Spring [closed]

Answer 1

I would say you have 2 options

1. Load the properties using
2. Use @PropertySource and the Environment abstraction.

Using

To simply load a properties file you can use the PropertiesFactoryBean or easier the tag (which uses the PropertiesFactoryBean underneath but is just easier to configure). See here for more information.

Simply add the following to your xml configuration

Now you have a Properties bean named transactions which you can inject into your controller after which you can use that to obtain the property you need.

@Autowired
private Properties transactions;

Using @PropertySource and Environment abstraction

Another solution is to add a @Configuration class with a @PropertySource to load the properties. After that you can use the Environment to obtain the properties. See the Environment section in the reference guide for more information.

@Configuration
@PropertySource("classpath:transaction.properties")
public class MyConfiguration {}

In your controller you can use the Environment to obtain the properties.

@Autowired
private Environment env;

Resource Support

Of course the Spring property support is usable with the Resource loading approach of Spring. So file: and http: prefixes work as well, as well as the default loading rules applying to the used ApplicationContext.
