So I am building a spring boot web application, packaging as a war, and deploying to a tomcat application server.
I have the following dependency in my pom.xml for tomcat:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
The scope of this dependency needs to be provided in order to be able to deploy it to a tomcat instance. However, when I want to run the war via the spring boot CLI or via IntelliJ's default spring boot run configuration, I need to remove the <scope>provided</scope> in order for it to run the embedded tomcat.
My question is, is there some way to make the dependency conditionally provided based on an active spring profile, or some other method?
In your specific case, you can just do :
In the dependencies to run spring-boot with embedded tomcat :
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
And in a profile to deploy under tomcat
<profile>
<id>tomcat</id>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
</dependencies>
</profile>
After, to build for a specific profile
mvn clean install -Ptomcat
You can't control dependencies via spring profiles. However you can control spring profiles by maven profiles and it can solve your problem.
You can declare several maven profiles in your application and provide different set of dependencies for each of them.
Then you can configure maven profiles to use particular spring profile.
Take a look on maven profiles and an example of such configuration in this thread
This is a solution that will work with both, jar and war packaging:

Main class, that goes in <start-class> in pom.xml:

I have gone through all the articles available in and out stack over flow. But my problem is not resolved. I have a working java 8 which works fine on my all applications with in eclipse and also i have tried to run with cmd. it means class path, environment variable etc, all works fine. Now i want to create a Spring boot project, so when ever i run an spring boot project using both Run As Java Application & Spring Boot App, It Gives This Error "Error: Could not find or load main class package.classname" Here is the Screen Shot:
Note: I have tried almost every thing, like clean project, checking environment variables, updated eclipse etc. This problem is with only a spring boot application. All other Java applications works fine.
Here is my pom.xml file.

Right click on your project. Select "Run As" -> "Maven build...". Then in "Goals" field, enter "spring-boot:run". Apply & Run.
I want to deploy web application that use jsp files using executable jar(Spring boot)
Project structure:
1)in src\main\resources\META-INF\resources\WEB-INF\jsp folder i put my jsp files
2)app.prop file
spring.mvc.view.prefix : /WEB-INF/jsp/
spring.mvc.view.suffix : .jsp
3)Controller:
#Controller
#RequestMapping("test")
public class TestController {
#RequestMapping(method = RequestMethod.GET)
public String test(){
// System.out.println("Inside controller");
return "test";
}
}
When i build it using mvn package it create jar file, to run jar file I have two options:
1)java -jar MyJar
2)mvn spring-boot:run
When i use mvn spring-boot:run and go to localhost:8080/test my browser show me content of test jsp file
When i use java -jar Myjar.jar and go to the same url i gor an 404 error
There was an unexpected error (type=Not Found, status=404).
/WEB-INF/jsp/test.jsp
I can't always use mvn spring-boot:run because i will deploy jar to remote server. How to solve this problem?
BTW this is my pom

java -jar Myjar.jar command do not deploy your application to embeded tomcat. If you want to use separate application server you can find out your application output in
/target
directory and you need to deploy it.
I am pretty new to Spring Boot and I have completed a application that works well on my localhost. As I have been told to deploy it outside my localhost on for example a webbhotel or simular I need to export the project as a war-file and not as a jar-file.
UPDATE!!
I run the project as a Springproject generated in Spring Initialzr and using Eclipse as a IDE.
In Eclipse I have followed the steps
<packaging>war</packaging>
and
<dependencies>
<!-- … -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<!-- … -->
</dependencies>
from Spring Boot Referencepage
https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file
In my project I use
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
Do I need to add the sprinng-boot-starter-tomcat dependency and add provided to that on aswell as tomcat-embed-jasper so that my dependency will be like this?
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
When I try to export to war-file in Eclipse, Eclipse can't find my project. It can find it if I try to export Java>JAR FILE but not if I try Web>WAR FILE
Do anyone know what I am doing wrong and if it is neccesary to export to a WAR-file to deploy to a external server?
You need to extend ****SpringBootServletInitializer**** in your #SpringBootApplication
You don't need to add the ****sprinng-boot-starter-tomcat**** dependency for war file generation
Use below configuration in pom.xml
<packaging>war</packaging>
Configure Build Path for your project and select JDK
Right click on project > Run As > Maven Install
It will generate the war file inside target folder.
Copy this war and deploy to any web/application server (I have renamed it to demo.war).
You can access the app by using your host name followed by the port and app name.
To generate WAR file in STS (Spring Tools Suite):
Run as-> Maven Install
After change to <packaging>war</packaging> in pom.xml.
utilize the command: mvn package
You can also proceed by selecting menus File -> Export -> Web -> War file
I generated a war file by the following steps:
Add above dependency.
Open command prompt.
cd into your project directory.
Run the command: mvn clean install.
Then a war file will be generated in the target directory.
If you are using maven, you can add tag to specify the type we want to create - jar or war. After that in sts you trigger a maven build and specify the goals - clean install and specify the number of threads you want to run for the build. In case you want to skip the test case you can give skipTest =true, or if you to run from command prommpt you can give -Dmaven.test.skip=true.
Once done, war file will be generated under target folder. (unless we specify a specific deployment folder)
Step1:- Create ServletInitializer file by extending SpringBootServletInitializer
public class ServletInitializer extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(DemoApplication.class);
}
}
Step2:- Use #SpringBootApplication in main class
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
Step3:- Package type as war in pom.xml
<packaging>war</packaging>
Step4:- Give build filename as like this
<build>
<finalName>demo</finalName>
</build>
Step5:- Add external tomcat dependency as provided scope
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>

I had deploy maven project built in war package to Jboss EAP 6.4 and successfully, WAR package deployed. I had created services and run with spring-boot in local eclipse and I can ran in browser but I have a problem when access that URL based on war package in Jboss eap. I success ran jboss service but cannot run the URL. for example, I have service with method GET with url: localhost:8080/letter-printing-eap-generator/testing cannot run in jboss but ran in local eclipse before deploy. how to fix this problem? any configuration xml in maven project? I just add jboss plugin. thanks. my code:

SpringBootRestApiApp.java

public class SpringBootRestApiApp {
public static void main(String[] args) {

map.put("status", "200");
map.put("message", "ini messagenya");
map.put("content", "mantap");
return map;
}
}
this is my project structure:
application.yml :
server:
port: 8080
contextPath: /letter-printing-eap-generator
In the absence of any specific configuration, JBoss EAP will provide access to your web application at a context with a name that matches the WAR file name.
Therefore, your application should be accessible at:
http://localhost:8080/letter-printing-eap-generator-0.0.1-SNAPSHOT/testing
A common way of changing this for development purposes is to include a finalName element in the pom.xml file:
<build>
<finalName>${project.artifactId}</finalName>
...
</build>
This will generate a WAR file named letter-printing-eap-generator.war and the original URL that you tried should work.
Alternatively, you could add a jboss-web.xml file to your deployment (in the WEB-INF directory) that contains a context-root element:
<jboss-web>
<context-root>letter-printing-eap-generator</context-root>
</jboss-web>
You could also do this using the JBoss CLI or the web console to perform deployment as well.
I have created a simple server that uses JPA repository and returns a response in Json. It includes methods post and get. It is a spring starter boot app project and everything works on my localhost (I use postman to send and receive json objects). My problem is when I try to deploy to Heroku I run into many problems. I added a jetty-runner dependency and plugin. I also created a procfile as shown below:
web: java $JAVA_OPTS -jar target/dependency/jetty-runner.jar --port $PORT target/*.war
Initially the target folder was empty and foreman start web was saying that it couldn't find my war file, so I added the following line to pom.xml:
<packaging>war</packaging>
But the project created an error, so I disabled maven nature of the project, then configured maven again and then it included pom.properties and pom.xml in the target folder. When I tried to deploy it, it said it was unable to access jetty jar file in target/dependency because there was no folder like that. So I did maven install and it installed the missing folders. Now I get the error that No transaction manager can be found, so I installed a dependency for jetty-plus and Atomikos. But now I still get the error that there is not transaction manager found and there is a java.net.bindexception.
I feel like I am really on the wrong path. I was wondering if anyone can tell me from the beginning on how to deploy a spring starter boot project to heroku. Any help would really be appreciated.

I found out that the deploying a spring boot application is a little different then deploying spring boot mvc project. Basically you don't need a jetty-runner dependency or plugin, you just do the following steps:
Configure a mvn project
mvn clean and install
Declare Procfile as: web: java $JAVA_OPTS -Dserver.port=$PORT -jar target/*.jar
All found from this site:
http://web.archive.org/web/20171018145733/http://nicholaspaulsmith.com/spring-boot-on-heroku/
I outlined some details in my blog
https://exampledriven.wordpress.com/2016/11/04/spring-boot-heroku-example/
The main point is to use the heroku maven plugin like this
heroku plugins:install heroku-cli-deploy
mvn clean install
# Creates an app with the specified name, without setting up a git remote
heroku create <APP-NAME> --no-remote
#deploys the jar file
heroku deploy:jar target/demo-0.0.1-SNAPSHOT.jar --app <APP-NAME>
but there are more details like how to set up a CI/CD pipeline
