I am using spring integration to pull data from source into database.
JdbcMessageHandler is used to handle the db inserts,
Is it possible to attach to ServiceActivator to RetryTemplate (with ExponentialBackOffPolicy) in order to retry if there are db connection related errors?
tried this
@ServiceActivator(inputChannel = "DatabaseOutput", adviceChain = {"retryAdvice"})
public MessageHandler jdbcMessageHandler() {
JdbcMessageHandler jdbcMessageHandler = new JdbcMessageHandler(getDataSource(),...);
}
@Bean
public RetryTemplate retryTemplate() {
RetryTemplate retryTemplate = new RetryTemplate();
...
return retryTemplate;
}
@Bean
public RequestHandlerRetryAdvice retryAdvice(RetryTemplate retryTemplate) {
RequestHandlerRetryAdvice advice = new RequestHandlerRetryAdvice();
advice.setRetryTemplate(retryTemplate);
return advice;
}
When I started the app, I gave it wrong host and expecting it to try n-times , where n is retryPolicy.setMaxAttempts(99) that I set on the RetryTemplate.
But instead it failed immediately

This has nothing to do with your JdbcMessageHandler. It fails much earlier than you try to send a message: on start up when Spring Boot tries to initialize data base via scripts. At the moment you just don't say to Spring Boot that you use a PostgreSQL, so it tries to resolve it via DataSource. Even if you would say it still will fail because Spring Boot won't be able to initialize DB with respective scripts.
Please, see if you can simulate some other error to let your application to pass down to message exchanges.
