how can i achieve early initialization of beans like spring @configuration

[sdyava]

i'm new to micronaut, how can i achieve what spring achieves with @configuration. Here is the sample code. I tried @context and @singleton, but with no luck.

@configuration
@EnableBinding(Sink.class)
@slf4j
@Profile("default")
@component
public class StreamConfig {

@Autowired
private Environment env;


@Bean(name = "sslproperties")
public Properties entityManagerFactory() {

   
    System.setProperty("javax.net.ssl.trustStore", env.getProperty("spring.kafka.ssl.trust-store-location").replaceAll("file://", "").replaceAll("file:", ""));
    System.setProperty("javax.net.ssl.trustStorePassword", env.getProperty("spring.kafka.ssl.trust-store-password"));
    System.setProperty("javax.net.ssl.keyStore", env.getProperty("spring.kafka.ssl.key-store-location").replaceAll("file://", "").replaceAll("file:", ""));
    System.setProperty("javax.net.ssl.keyStorePassword", env.getProperty("spring.kafka.ssl.key-password"));
    System.setProperty("javax.net.ssl.trustStoreType", "jks");


	return System.getProperties();
}

More information is required, what didn't work for you with @Context?

[sdyava]

Here is what i'm trying with @context . I just want to initialize system variables on the server start up. please help me on what i'm missing here.

@context
public class ConsumerStreamConfig {
@value("trust-store-location")
String trustStore;
@value("trust-store.password")
String trustStorePwd;
@value("key-store-location")
String keyStore;
@value("key-store.password")
String keyStorePwd;

@Context
public Properties entityManagerFactory() {

    System.setProperty("javax.net.ssl.trustStore", trustStore);
    System.setProperty("javax.net.ssl.trustStorePassword", trustStorePwd);
    System.setProperty("javax.net.ssl.keyStore", keyStore);
    System.setProperty("javax.net.ssl.keyStorePassword", keyStorePwd);
    System.setProperty("javax.net.ssl.trustStoreType", "jks");




	return System.getProperties();
}

}

ConsumerStreamConfig needs to be annotated with @Factory and the entityManagerFactory method with @Context

[sdyava]

Thank you for answering . Cant i refer @value here. trying to inject below values from application.yaml
@factory
public class ConsumerStreamConfig {
@value("kafka.ssl.truststore.location")
String trustStore;
@value("kafka.ssl.truststore.password")
String trustStorePwd;
@value("kafka.ssl.keystore.location")
String keyStore;
@value("kafka.ssl.keystore.password")
String keyStorePwd;

application.yaml

kafka:
ssl:

keystore:
  #location: ${KEYSTORE_LOCATION:/app/certs/prod/keystore.jks}
  location: ${KEYSTORE_LOCATION:src/main/resources/certs/dev/keystore.jks}
  password: ${KEYSTORE_PASSWORD:******}
truststore:
  location: ${TRUSTSTORE_LOCATION:src/main/resources/certs/dev/truststore.jks}
  password: ${TRUSTSTORE_PASSWORD:****}

[sdyava]

had to ${"kafka.ssl.truststore.location"}, this worked.

[sdyava]

sorry i meant creating bean like this

@bean
public Properties entityManagerFactory() {

System.setProperty("javax.net.ssl.trustStore", trustStore);
System.setProperty("javax.net.ssl.trustStorePassword", trustStorePwd);
System.setProperty("javax.net.ssl.keyStore", keyStore);
System.setProperty("javax.net.ssl.keyStorePassword", keyStorePwd);
System.setProperty("javax.net.ssl.trustStoreType", "jks");




return System.getProperties();

}
