I have a Web Application that is environment independent so it's a single war that can be deployed to multiple environments.
I have created multiple Tomcat Servers (i.e. Devel, QA, Production) and defined them in in the NetBeans server configuration.
I'm able to run the war against each of the environments fine by manually changing the project properties but I would like to be able to set what server to connect to from within Maven and either add custom Debug/Run actions or by using maven profiles.
I've tried setting:
<netbeans.deployment.server.id>tomcat70:home=C:\Apache\Tomcat\7.0.34,base=C:\Apache\Tomcat\Devel</netbeans.deployment.server.id>
but that didn't work for me.
Does anyone know if this can be done?
Thanks,
Rob
The proper way to do this is to setup separate profiles in your pom and then have the property set in each of those profiles.

In my POM I have two profiles, Dev and Prod but there's also dependencies not enclosed within those profiles.Does it mean that there's a default profile too?
When you do Run Application from within Intellij which profile does it use to run the app? the default,ther prod or the dev? Under the maven panel you can check a profile, Dev or Prod but you can also not check anything.Does this play a role when you do Run Application?
What is very strange is that in the default profile I exclude the embedded tomcat from spring-boot-starter,but still when I do run application it loads it!, while
mvn dependncy:tree shows that tomcat is not included.
In IntelliJ you can create multiple run configurations (it’s a dropdown next to the run button). Within a configuration you can specify the active profiles you want to use.
I understand there's multiple ways of handling application property files and profiles in Spring Boot and I've seen multiple questions and answers on how to handle each but I'm trying to find the "best" way of handling it for a new project, if there is one.
The application is hosted in Weblogic 12c on production/pre-prod (with a jndi database connection) and ran locally in tomcat (with hardcoded database details) for development. I'd like it so that when the project is built via gradle and deployed to production it uses the jndi properties file and when ran locally it defaults to the hardcoded datasource with minimal changes required.
src/main/resources/application.properties
# DEV
spring.datasource.url=
spring.datasource.username=
spring.datasource.password=
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
# DEV
# PROD
# spring.datasource.jndi-name=
# spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
# PROD
From my understanding the recommended way is to externalize the property files and place the required one in a config directory alongside the WAR file for any differing config which is then automatically picked up and used?
You should consider creating multiple profiles. This means: Either multiple properties-Files, or multiple profiles in one file:
See https://docs.spring.io/spring-boot/docs/current/reference/html/howto-properties-and-configuration.html
I would recommend to use multiple application-ENV.properties, e.g.
application-prod.properties and application-preprod.properties.
There is always one active profile and settings from the application.properties (without any profile suffix) are used as default values if not overwritten in a specific profile-file.
Depdending on your environment (local, prod etc.) you should set an environment variable (start the java-process/application server with that environment variable), e.g.:
SPRING_PROFILES_ACTIVE=prod
On your local machine you would set:
SPRING_PROFILES_ACTIVE=dev
With this variable you can control, which profile is currently active.
Also consider integrating the active profile into you Continious Integration/Deployment settings.
Please note that putting plain text passwords hardcoded into committed files is not a good idea. Consider using jasypt or a spring cloud config server for your prod database configuraiton or use any mechanism that your cloud provider provides to you if you use any. Microsoft Azure for example provides a KeyVault for sensitive data.

If you use gradle good solution is to set application.properties and test.properties files and put into them properties for prod and preprod respectively.
Then run application with different vm arguments: -Dspring.profiles.active=test for test.properties and without arguments for application.properties
Use gradle instruments and configure them once for test and prod. For example: gradle bootWar configure without vm arguments, gradle bootWarTest with vm arguments -Dspring.profiles.active=test. Save once you configs and you will create war for different environments only selecting between two buttons in gradle.
Hi I want my spring boot web project to be deployed both on development and production environment and it should be run on specific profile based setting.
I googled on how to do that, and first of all that I have searched is defining application-{profile name}.properties properly in the src/main/resources classpath.
Now the problem is how to set profiles.
Since I am working on tomcat 8 in linux, there should be some configuration but I don't know how to do that.
and I am also curious that when my project is packaged as war file, java -jar {filename} -Dspring.active.profile=blahblah will not be work, but I think there is an alternative way.
plus, is there an way to set profile on tomcat 8 in Windows 10 ?
Thanks you
First:
I will recommend get rid of dedicated tomcat server and use embedded tomcat, jetty etc. Build your web apps as jar files and just run them. (of course if you don't have any limitations)
Second: You can do this either system property or env variable.
If you go with system property (order is important)
java -Dspring.profiles.active=blahblah -jar {filename}
If you go with env variable you need specify
SPRING_PROFILES_ACTIVE=blahblah
I am trying to find the best way to configure my Spring Boot Web application to easily switching between the following data sources for both local testing and deployment.
H2 in memory db. Local testing only.
Dev oracle. Local testing and deployment.
Prod oracle. Deployment only.
By local testing, I mean to test in IDE environment (Eclipse). Dev and prod oracle databases are set up on two remote servers.
After some research, there are different ways to switch from one data source to another.
Use Spring profile. Using H2 and Oracle with Spring Boot. Set up the following files in classpath, application.properties, application-h2. properties and application-dev.properties. While connections for h2 and dev are defined in corresponding properties files, spring.profiles.active is set in application.properties. My understanding is this property can be overridden during build process by specifying spring.profiles.active. However, it seems to be a JVM variable, how do I set it running maven?
Maven profile. Create multiple profiles in pom and a filter pointing to application properties files. The profile specified by -P option during maven build will determine which application properties file to look. However, according to maven application with multi environment configuration can't deploy on tomcat, this will generate multiple wars for different deployment. So method 1 is preferred. Plus, it does not apply to switching datasources while testing locally.
Persistence units. Define different persistence units for different data sources in persistence.xml. Use EntityManager by choosing a specific unit. Variation of this method include having a variable in unit names which is determined in application.properties.
JNDI lookup. Set up a jndi name in application.properties with spring.datasource.jndi-name. The actual database information including url and credentials will be specified in context.xml in the tomcat folder where the war will be deployed.
My mind is set on local testing environment. Gonna go with method 1. Switching between H2 in memory and oracle is so easy just by changing the property in application.properties. Since the testing is usually done in IDE, war does not need to be generated, although answers are welcome for run maven install with spring.profiles.active.
As far as deployment, JNDI is definitely the way to go. However, I am concerned that the two properties in application.properties: spring.profiles.active and spring.datasource.jndi-name may be conflicting with each other. If I have spring.profiles.active=h2 and then tried to deploy the war to prod server, does it try to connect to h2 based on the spring profile or to prod db based on jdni-name? What is the best practice to accommodate all scenarios with enough flexibility?
Also is a explicit configuration class for DataSource required such as Configure Mutiple DataSource in Spring Boot with JNDI? My understanding is application.properties and spring profile should be enough to handle it, right?
Definitely use Spring profiles.
You don't want to use Maven profiles as it creates different artifacts. Ask your QA/Release engineers how they feel about having different artifacts for different environments :). They wouldn't be happy.
H2 is what you want to use in CI server integration testing as well. Such integration testing is fast and easy.
Instead of changing profile in application.properties, consider defining profile via command line parameter. So that configuration file changes are not required to run your application in different profiles.
We are working with a Spring 3 application that runs on several environments (test, UAT and Production) these environments are managed by a third party company so we have almost no access to the servers.
We have tried with Jboss System Properties and Maven2 Profiles. Both solutions worked fine, however we don't want to tie the application to one specific Server (Jboss in this case) and we don't want to do environment specific builds (required for Maven2 profiles).
Is there a good way we could have environment specific properties for the app that do not require different builds for each environment and require no modifications on the server side and that could also run on different servers? (some sort of PropertyPlaceHolderConfigurer that could read property files outside the app context should do the trick)
Environment-specific builds are not a bad option.
But spring 3.1 is providing what you are looking for - environment specific configuration. See this and this
