We recently upgraded our project from Grails 3 to 5.1.1. Actually, it was not really an upgrade but rather a migration. We ended up creating a fresh project with 5.1.1 and migrated all of our code into it. Everything is currently working with an exception of one warning:

QUESTION
I have a multimodule Maven project where parent pom is as follows
...ANSWER
Answered 2022-Jan-12 at 10:04You have declared 'org.springframework.boot' as the parent module of both modules. So if some jars and artifacts like 'com.amazonaws' do not exist in 'org.springframework.boot', they won't be resolved in your project. These dependencies are not announced in 'Spring' module in your project and whatever you have declared in it, can be found in 'org.springframework.boot', then resolved. If you do not declare a 'version' tag in your pom, I guess the version of the parent (here 2.6.1) will be considered for your module version.
QUESTION
In my java application I need to write data to S3, which I don't know the size in advance and sizes are usually big so as recommend in the AWS S3 documentation I am using the Using the Java AWS SDKs (low-level-level API) to write data to the s3 bucket.
In my application I provide S3BufferedOutputStream
which is an implementation OutputStream
where other classes in the app can use this stream to write to the s3 bucket.
I store the data in a buffer and loop and once the data is bigger than bucket size I upload data in the buffer as a a single UploadPartRequest
Here is the implementation of the write method of S3BufferedOutputStream
ANSWER
Answered 2022-Jan-05 at 15:03You should look at using the AWS SDK for Java V2. You are referencing V1, not the newest Amazon S3 Java API. If you are not familiar with V2, start here:
Get started with the AWS SDK for Java 2.x
To perform Async operations via the Amazon S3 Java API, you use S3AsyncClient.
Now to learn how to upload an object using this client, see this code example:

Things worked fine in 2021.2 but when same project opened in 2021.3 then stated to got following error
...ANSWER
Answered 2021-Dec-06 at 11:192021.3 IDE version has updated the version of the bundled Maven to 3.8.1
. In this version, Maven blocks the access to http
repositories by default. Before that, Maven itself has moved from using the http repositories.
So now one needs to explicitly configure Maven to allow http
repositories if they are used in the project. E.g. in settings.xml
add a mirror to your http repository that allows HTTP:
QUESTION
I am trying to implement AWS SQS FIFO queue using spring boot(v2.2.6.RELEASE).
Created a queue, "Testing.fifo" in aws. Left all other fields to default while creating the queue.
My producer and consumer to the queue run on a single service.
code to put messages to queue
...ANSWER
Answered 2021-Dec-03 at 06:47This might help: The message group ID is used for ordering of SQS messages in groups.
So, if you have multiple group IDs like 1 and 2, then within those groups, the SQS messages will always be in order. The ordering will be preserved relative to the group and not the queue as a whole.
This can be used in cases like, if you are sending out events for different user details updates, you would want to group the data for a particular user in order, and at the same time you don't care about the ordering of the queue as a whole. You can then set the group ID as the unique user ID in this case.
If there is no use-case of creating groups, and there is only one group and you want the message order to be preserved as a whole, just use the same groupID for all messages.

Implement the DaprObjectSerializer interface. See this class as example.
Use your serializer class in the following scenarios: When building a new instance of DaprClient: DaprClient client = (new DaprClientBuilder()) .withObjectSerializer(new MyObjectSerializer()) // for request/response objects. .withStateSerializer(new MyStateSerializer()) // for state objects. .build(); When registering an Actor Type: ActorRuntime.getInstance().registerActor( DemoActorImpl.class, new MyObjectSerializer(), // for request/response objects. new MyStateSerializer()); // for state objects. When building a new instance of ActorProxy to invoke an Actor instance, use the same serializer as when registering the Actor Type: try (ActorClient actorClient = new ActorClient()) { DemoActor actor = (new ActorProxyBuilder(DemoActor.class, actorClient)) .withObjectSerializer(new MyObjectSerializer()) // for request/response objects. .build(new ActorId("100")); }
