Unable to read application.yml in Condition class - spring

Question

I have this class
#Service
#Conditional(MyCondition.class)
public class Class1 implements AcknowledgingMessageListener<String, GenericRecord> {
#Value("#{'${audit.module}'}")
private String xyz;
Here is MyCondition
#Configuration
#Component
#EnableConfigurationProperties
#ConfigurationProperties("audit")
public class MyCondition implements Condition {
#Value("#{'${audit.module}'}")
private String ss;
}
The problem is in MyCondition #Value is unable to read the value from from application.yml.

Answer 1

MyCondition is not a spring managed bean when you use it as a #Conditional. So you can not use #Value inside MyCondition. However there are some workaround.
You can set String ss as static and add one setter value with #Value.
#Component
public class MyCondition implements Condition {
private static String ss;
#Value("${audit.module}")
public void setSs(String ss) {
MyCondition.ss = ss;
}
#Override
public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata) {
return true;
}
}
But this value will be set after Class1 has been created, so at the time on validating #Conditional ss will be null.
But I think you will need to use the value of ss inside the matches method. So inside the matches method you can access property values with ConditionContext
public class MyCondition implements Condition {
#Override
public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata) {
System.out.println(context.getEnvironment().getProperty("audit.module"));
return true;
}
}
