How to configure the annotaion value with configuration file like .properties/.xml/.yml in spring framework?

Question

A code snippet for a specific case

@Configuration
@NewEnableRedisHttpSession(maxInactiveIntervalInSeconds = 900)
@Import({RedisConfiguration.class})

Here is a annotation value: maxInactiveIntervalInSeconds = 900

@NewEnableRedisHttpSession(maxInactiveIntervalInSeconds = 900)

I want to configure it like

@NewEnableRedisHttpSession("${maxInactiveIntervalInSeconds}")

some configuration file will give the value maxInactiveIntervalInSeconds = 900

use

@EnableRedisHttpSession(maxInactiveIntervalInSeconds = intervalInSeconds)

more specific for your need

@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 900)

default value is 1800 .

Supplement based on comment. Do like this, in case you want get value from application.properties

spring.session.timeout=9000

@Value("${spring.session.timeout}")
private Integer maxInactiveIntervalInSeconds;

Thanks for you reply! Does`@EnableRedisHttpSession(maxInactiveIntervalInSeconds = intervalInSeconds)` means I can set intervalInSeconds in configuration file ? I know I can give a value to `maxInactiveIntervalInSeconds`, but what I need is to set the value in **configuration file**. – wo4wangle Nov 17 '21 at 07:33
Yes, you can set value in `application.properties` or another `*.properties` file. See more in my edited answer. – Vy Do Nov 17 '21 at 07:58
Cool, I will have a try. – wo4wangle Nov 17 '21 at 08:05
You can set key as another string, for example `spring.session.timeoutFooBar=900` , `spring.session.timeoutFooBarZuu=1900` ; then change accordingly at `@Value("${spring.session.timeoutFooBarZuu}")` – Vy Do Nov 17 '21 at 08:11
Seems work, you save my days！Thanks – wo4wangle Nov 18 '21 at 01:51
