How can I specify spring active profile while running spring boot application (as a war) in WebLogic? How to pass different -Dspring.profiles.active JVM arguments for different application deployed?
All suggestions welcome!
Thanks,
They are different ways to specify a profile in spring boot.
In your case, the better way is to add the property spring.profiles.active inside the application.properties, to avoid pasing it as argument when you launch the apps.
I hope my response help you.
Good luck

I'm totally new to Kafka and terribly confused by this:
https://docs.spring.io/spring-kafka/reference/html/#with-java-configuration-no-spring-boot
I don't understand what that even means. What does "no spring boot mean" because that example sure as hell uses spring boot. I'm so confused....
EDIT
if I'm using SpringBoot and spring-kafka, should I have to manually create #Bean ConcurrentKafkaListenerContainerFactory as shown here. Most of the examples in the docs for setting up filtering / config / etc seem to use the "manual" configuration using #Bean. Is that "normal"? The docs are very confusing to me...especially this warning:
Spring for Apache Kafka is designed to be used in a Spring Application Context. For example, if you create the listener container yourself outside of a Spring context, not all functions will work unless you satisfy all of the …Aware interfaces that the container implements.
It's referring to the autowired configuration, as compared to putting each property in the config via HashMap/Properties in-code.
Also, it does not use #SpringBootApplication or SpringApplication.run, it just calls a regular main method using a hard-coded Config class.
Spring boot contains the functionality of AutoConfiguration
What this means is that spring boot when discovers some specific jar dependencies it knows, in the project, it automatically configures them to work on a basic level. This does not exist in simple Spring project where even if you add the dependency you have to also provide the configuration as to how it should work in your application.
This is also happening here with dependencies of Kafka. Therefore the documentation explains what more you have to configure if you don't have spring-boot with auto-configuration to make kafka work in a spring project.
Another question asked in comment is what happens in case you want some complex custom configuration instead of the automatic configuration provided while you are in a spring-boot app.
As documented
Auto-configuration tries to be as intelligent as possible and will
back-away as you define more of your own configuration. You can always
manually exclude() any configuration that you never want to apply (use
excludeName() if you don't have access to them). You can also exclude
them via the spring.autoconfigure.exclude property.
So if you want to have some complex configuration which is not automatically provided by spring-boot through some other mechanism like a spring-boot specific application property, then you can make your own configuration with your custom bean and then either automatic configuration from spring-boot for that class will back of as spring does several intelligent checks during application context set up or you will have to exclude the class from auto configuration manually.
In that case you could probably take as an example reference of how to register manually your complex configurations in spring boot what is documented on how to be done in non spring boot app. doc

Take a look at Spring Boot Cloud Config. It allows you to manage your config files centralized and has the ability to push new configurations to the connected applications.
I came across a requirement of switch on/off case in Spring Boot Application. We have a notification service implemented which is working on property :
notifyall = true in application.properties file.
Now I want to stop the notification services by specifying notifyall = false in application.properties file without any downtime.
Is it possible in Spring Boot Application?
If yes, then any step wise approach or relevant tutorial will be of great help.
Thanks
Use spring boot actuators.
Please go through the following link: https://projects.spring.io/spring-cloud/spring-cloud.html#_environment_changes
it mentions #ConfigurationProperties with prefix; any change in the configuration will be loaded automatically.
Is it possible to integrate activiti explorer maven plugin with activiti Spring boot app?, so that we can make use of activit-explorer to view deployed process in activit-spring boot engine.
I know we can use rest-api over spring boot to query process engine, but I want to know if it is possible to run the explorer over spring boot by adding it as a maven plugin during deployment?Or can we tweak the activit-explorer.war somehow to point to spring-boot activiti engine?
activiti-explorer.war is standalone webapp by itself. I've write some guideline on how to manually to embed activiti-explorer to you own app. http://blog.canang.com.my/2016/05/12/embedding-activiti-explorer-to-your-application/
Most probably step 5 in my blog is your solution.
btw, there's reason why the name is 'default'. I can't recall it atm
I thought of answering my own question so that it will be useful for other developers with similar requirement. If you want to make an eco-system where activiti-rest, explorer and your custom end points co-exist, please refer this thread from activit forum. I have tried this and is working fine. link to thread
I would like to give my observation here. In order to avoid getting into pulling source and trying to build myself, I achieved partial success, by installing the activit-explorer as part of the usual standalone installation.Started the standalone activiti-explorer using Apache-Tomcat but I configured the database for Activiti as same as (MYSQL in my case) I used in my spring-boot application to hit the common ground.
But apparently the activiti version in my spring boot app was 5.19.0.0 and that for activiti-explorer was 5.22.0.0, which created some misalignment for spring boot application startup to fail. I am hopeful that with matching versions it might succeed. When I get some more time on me I will try and update. Since then may be someone can use this route.
Currently in our project, we are using Spring Integration to integrate many service and some protocol related endpoints.
The project is a multi Spring Boot applications, more than one executable jars will be deployed in production.
The question is:
How to run an end to end test which needs to run cross some of these applications, I have to run the one by one manually? In before none-Spring-Boot applications, I can use Maven tomcat7 plugin to complete this work(deploy the wars into an embedded tomcat and run it in pre-integration-test phase), now how to start up all related applications before I run my test. Assume I do not use Docker/Vagrant now.
Similar question found on stackoverflow, End to end integration test for multiple spring boot applications under Maven
How to run the end2end test automatically?
In an Spring Integration test, sometime I have to mock a http endpoint, so I wrote a simple Controller in test package to archive this purpose, but I want to run it at a different port, which make it more like an outside resource. How to run different #SpringBootApplicaiton classes at varied ports at the same time in the test for this purpose?
I am using the latest Maven, Java 8, Spring Boot 1.3.1.RELEASE.
Actually, Spring Boot comes with the embedded Servlet Container support. One of them is exactly Tomcat. The default on for the org.springframework.boot:spring-boot-starter-web.
With the org.springframework.boot:spring-boot-starter-test and its #SpringApplicationConfiguration and #WebIntegrationTest you can achieve your requirements, even with the random port.
Please, refer to the Spring Boot Reference Manual for more information:
To change the port you can add environment properties to #WebIntegrationTest as colon- or equals-separated name-value pairs, e.g. #WebIntegrationTest("server.port:9000"). Additionally you can set the server.port and management.port properties to 0 in order to run your integration tests using random ports.
With that your #SpringBootApplicaiton will be deployed to that embedded Tomcat and your test can get access to the ran services/controllers.
Note: it doesn't matter if your Spring Boot application has Spring Integration facilities. The behavior is the same: embedded Servlet Container and integration tests against #Value("${local.server.port}").
