QUESTION
I have a spring boot 2 app which connects to Mariadb database. This app runs in cloud foundry. It takes database connection properties from VCAP_* env variable.
App works fine and can connect to database. But, I have found out that app is not using hikari configuration specified in application.yml.
Can you please suggest what is wrong here?
build.gradle

Answered 2021-Apr-02 at 13:45You are using the Spring Cloud Connectors library to create the database connection.

I have a spring boot application that would run on a local server (not on a google cloud server). I plan to use a service account to allow the application to use Google Cloud Storage and Logging. I created a service account and an api key and downloaded the json file which looks like this:

I'm trying to provide CloseableHttpClient to Spring Cloud OpenFeign. Spring Cloud Open Feign Documentationsays it supports CloeableHttpClient. Spring documentation doesn't give any example of actually replacing the HTTP client.
Basically, I'm providing SSLContext to the HTTP client and I want Feign to use this SSLContext loaded client. How to inject this CloseableHttpClient into the Feign?
Following is my relevant configuration:

I'm trying to start an InboundChannelAdapter manually using a @Scheduled function. I think I'm setting up the message payload wrong but I'm not sure what to have it as. Here's the code:
...ANSWER
Answered 2021-Jun-11 at 07:39You are using an outdated API.
The annotation-based configuration model has been long deprecated in favor of functional programming model, so EnableBinding
, StreamListener
etc are on their way out.
For you case you can simply use Supplier with StreamBridge. See this section for more details. And then you can do programmatic start/stop binding using the available lifecycle features of spring-cloud-stream.
Now, that doesn't mean your other problem will be resolved, but without a full stack trace and sufficient detail (e.g., version of frameworks you are using) it is difficult to say.
QUESTION
I have an application with multiple suppliers. So, I'm trying to configure fixed-delay
for the specific supplier in Spring Cloud Stream. Example:
application.yaml
...ANSWER
Answered 2021-Jun-07 at 14:22Indeed this is not supported for functional programming model at the moment as it really violates a concept of microservices for which spring-cloud-stream was designed for, where one of the main principles is you do one thing and do it well without affecting others. And in your case (especially with sources) you have multiple microservices grouped together in a single JVM process, thus one service affecting another.
That said, feel free to raise an issue so we can consider adding this feature
QUESTION
I'm currently working on a microservices application for my internship using Consul for service discovery and feign clients for communicating between the services. When we started working on the existing project which already was built using microservices, we upgraded Spring boot to 2.4.3 & cloud to 2020.0.1, so that we could make use of Java 15 to use records instead of normal classes for dtos. The problem we have now is that, whenever we make a call to a composite service, that will try to retrieve data from multiple services (for example users and teams service), that we get the following stacktrace:

QUESTION
The title says it all. Is it possible to get spring-cloud-starter-sleuth working together with axon-tracing-spring-boot-starter?
current log output:
...ANSWER
Answered 2021-Jun-03 at 15:25It seems axon-tracing-spring-boot-starter
is using OpenTracing. OpenTracing is a tracing library that was abandoned and it has never reached a GA/stable release. So even if there would be an easy way, I would not use OpenTracing in production, I would try to move away from it.
From version 3.0, Spring Cloud Sleuth has abstracted the tracer away and it supports multiple tracer implementations. By default it supports Brave which is a mature tracing library but Sleuth has support for OpenTelemetry as well (Sleuth-OTel). The OpenTelemetry support is incubating and it is not recommended to use in prod since OpenTelemetry Tracing is not entirely stable/GA yet for Java.
With this, your options are:
- Add support to Axon for Brave
This is what I would recommend, I would start with opening an issue for them - OpenTelemetry theoretically compatible with OpenTracing (check the OpenTelemetry docs)
You might be able to use Sleuth-OTel and OpenTracing The problem with this is: OpenTracing is abandoned and never went GA, OpenTelemetry Java Tracing is not stable yet, Sleuth-OTel is not stable yet - You can implement OpenTracing support for Sleuth
I think this is a bad idea, it is a lot of work and OpenTracing is abandoned and never went GA
QUESTION
I am new to spring framework. I have a confusion regarding spring boot and spring cloud.
I used https://start.spring.io/ to initialize a spring boot application. I think I am using the spring boot framework. However, I would like to use some spring cloud dependencies such as spring-cloud-stream-binder-kafka.
Question 1: If I added this dependency above to my spring boot application, I am wondering if I still can go with the spring boot framework, or I have to change to spring cloud framework.
Question 2: I am wondering if there is any difference when deploying the spring boot or spring cloud application. Or, they just have the different frameworks, and we could deploy them in the same way.
Thank you so much!
...ANSWER
Answered 2021-Jun-02 at 21:04You can use together Spring Boot and Spring Cloud packages. Spring Boot is just a preconfigured Spring Framework with some extra functionalities. It also uses library versions compatibile with each other. Spring Cloud is also the part of the Spring ecosystem, contains libraries that mostly used in cloud applications. In the background, these packages will pull all necessary Spring (and other) libraries into your project, as transitive dependencies. So you can use the generated pom/gradle, and add other dependencies. In this case Spring boot will be your core and cloud add extras.

Install spring-cloud
You can use spring-cloud like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the spring-cloud component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
