I am migrating an application in WebLogic to Tomcat with spring boot.
I wonder about weblogic specific characteristics that does not exist in tomcat.
session handling, lookup services, transaction management.
How do I know whether or not they are used. If it is the case, how to resolve the problem in target server?
I have a Spring Boot application which contains a Spring Batch mechanism that we run without an endpoint (reading from an API and updating the database), and in my application.yml we have web-application-type: none.
My application is not runnable using gradle boot:run, but I need to monitor its performance using SBA, the application is deployed as a jar, and I am running it using a ksh script.
Can I use SBA on a none-web Spring Boot app? How can I deploy it so it can monitor a jar?
I just created a new application using Spring boot 2 M7 and I'm using spring-webflux.
I built the application as an autoexecutable war that I can start in dev with java -jar app.war and also on a standalone tomcat server for UAT purpose.
In the web reactive reference doc, I read
To deploy as a WAR to a Servlet 3.1+ container, wrap HttpHandler with ServletHttpHandlerAdapter and register that as a Servlet. This can be automated through the use of AbstractReactiveWebInitializer.
Baeldung site also wrote about it and they describe a procedure to register a servlet that wrap the router for a standalone environment.
Using Spring boot tomcat starter, I didn't need to do anything : no code about booting the server necessary ; the app starts using the embedded server. In debug I saw NIO access so all seems fine.
I didn't try yet but what will happen on a standalone tomcat using Spring boot tomcat starter and webflux starter ? Is spring boot take care of everything (embbeded and standalone tomcat) ? how does it work ?
When multiple spring boot applications created and deployed to a tomcat server. Is it possible to use a common connection pooling, datasource instead of providing these details in application.properties file. Or does this already taken care within the spring boot implementation
When you deploy multiple application then each application manages it connection pool.
Spring boot boundary is limited to each application context and it does not know what other application deployed and which db they are using.
I am trying to deploy multiple spring boot web app on tomcat. All have the same application.properties.How can I split the configuration files for different app running on tomcat.
Spring Boot doesn't require an external Tomcat, because it contains its own embedded Tomcat. So you can run all of your application in it's own Tomcat on the same machine. All you have to do is to define different ports for your applications via server.port property.
