Trying to use IP pattern filter provided by Micronaut framework. What I want is to inject the configuration at application startup. Right now yaml file takes a list of IPs as input. But to inject the configuration at runtime, how can I pass the list of IP's to this yaml property.
Current scenario
micronaut:
security:
enabled: true
ip-patterns:
- 127.0.0.1
- 192.168.1.*Not sure if the below thing will work
Expected
micronaut:
security:
enabled: true
ip-patterns:${list_of_Ip's}The ip-patterns is a list as you know and you can't represent ${} as a list. You can create a custom property source to convert the environment variable into the configuration.
For example:
public class Application {
public static void main(String[] args) {
String patternsEnv = System.getenv("SOME_ENV");
List<String> ipPatterns = Arrays.stream(patternsEnv.split(","))
.map(StringUtils::trimToNull)
.filter(Objects::nonNull)
.collect(Collectors.toList());
Map<String, Object> map = new HashMap<>(1);
map.put("micronaut.security.ip-patterns", ipPatterns);
PropertySource propertySource = new MapPropertySource("ip-patterns", map) {
@Override
public int getOrder() {
return 0;
}
};
Micronaut.build(null)
.mainClass(Application.class)
.propertySources(propertySource)
.start();
}
}
