We need help in a matter.
We are looking for a deployment solution for the project we are developing. We are using SpringSoft project as our project and MySQl as database. We are using Redis for session storage. We target 100 users in the first stage. In this context, we recommend which deployment solutions to consider pricing. (We developed the frontend with angular and used the amazon S3 service)

Hi All,
I've got a Spring Boot app that connects to an RDS Aurora instance through the usual spring.datasource property. But I want to now be able to connect to RDS and have access to a read replica. When I added properties for the DB instance and replica support, I got a strange error:code
.ApplicationContextException: Unable to start web server; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'servletEndpointRegistrar' defined in class path resource [org/springframework/boot/actuate/autoconfigure/endpoint/web/ServletEndpointManagementContextConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.actuate.endpoint.web.ServletEndpointRegistrar]: Factory method 'servletEndpointRegistrar' threw exception;code
Does anyone have an example of how to configure the app to hit the master and read-replica?
Thanks.
Les
All,
I am trying to use an Aurora MySQL cluster of 1 writer and 1 read replica.
I set up my properties as follows:
cloud.aws.rds.db-write-instance.username=ABCD
cloud.aws.rds.db-write-instance.password=pass
cloud.aws.rds.db-write-instance.readReplicaSupport=true
cloud.aws.rds-db-write-instance.databaseName=mydbBut when I look at processlist for the writer and read-replica hosts, only the writer has had any activity. Do I need additional configuration set up? This is a Spring Boot app integrated with Spring Cloud for AWS.
Thanks.
(The db instance name matches the master name)

"com.amazonaws.SdkClientException:Unable to find a region via the region provider chain. Must provide an explicit region in the builder or setup environment to supply a region." when I try to configure a AWSSimpleSystemsManagement client, some one can help me? I have an example in my github for exemplify my problem, follow https://github.com/omundodebob/springcloud-aws-config-poc. Note: The accessKey and secretKey is a fake, just to test this problem :).
I'm trying use the spring-cloud-aws-jdbc in my project, but when I receive a large number of user I have a problem, It seems like my pool of connections is full.
Exception: Pool empty. Unable to fetch a connection in 30 seconds, none available[size:100; busy:100; idle:0; lastwait:30000]
I have used C3P0 in it with no problem. Is possible I use C3P0 for pool connection instead Tomcat pool?

Hey guys ... question to spring-cloud-aws / multiple listeners on one queue
class A{
@SqsListener(value = "some-queue", deletionPolicy = ON_SUCCESS)
public void onMessageReceived1(String payload, @Header(TYPE) String messageType) {}
}
class B {
@SqsListener(value = "some-queue", deletionPolicy = ON_SUCCESS)
public void onMessageReceived2(@Payload SomeMessagePayload message, @Header(TYPE) String messageType) {}
}would that work? btw. is the Method Name taken into account?
I got "Ambiguous handler methods mapped for destination " when both methods are called "onMessageReceived"

Hi all, When i am using @SqsListener with Object its not getting the value
@SqsListener("Demo")
public void processMessage(Person person) {
System.out.println("Message Received - " + person.getName());
}I get the value - Message Received - null
When i debug i can see the GenericMessage payload with actual value. I thought If jackson library is in class path message converstion happens automatically
I have configured QueueMessageHandlerFactory with StrictContentTypeMatch- false
@Bean
public QueueMessageHandlerFactory queueMessageHandlerFactory() {
QueueMessageHandlerFactory factory = new QueueMessageHandlerFactory();
MappingJackson2MessageConverter messageConverter = new MappingJackson2MessageConverter();
//set strict content type match to false
messageConverter.setStrictContentTypeMatch(false);
factory.setArgumentResolvers(Collections.singletonList(new PayloadMethodArgumentResolver(messageConverter)));
return factory;
}
