How to start up spring-boot application via command line?

Question

I have a spring-boot application which I need to start up by going to the folder directory and start up my web application via command line. I have a class called Application.java and the code inside it is as followed.

@SpringBootApplication(scanBasePackages = {"com.ubs.tas.topcat.dashboard"})
public class Application extends SpringBootServletInitializer {
    private static final Logger LOGGER = LoggerFactory.getLogger(Application.class.getName());
    private static final Class<Application> applicationClass = Application.class;

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(applicationClass);
    }

    public static void main(String[] args) {
        LOGGER.info("Starting...");
        SpringApplication.run(Application.class, args);
    }
}

I set up classpath then tried to run the command "java ApplicationUtility" but I'm getting this error message "Could not find the main class: ApplicationUtility. Program will exist."

What kind of project? For example, if you're using Maven with the appropriate plugin mvn spring-boot:run will work. Did you read the docs? — jonrsharpe

Thing is, if you try java.exe, you will need to set classpath, which is a nightmare. But the classpath is already available in pom.xml or gradle.build. So Maven and Gradle provide plugin(maven)/task(gradle) to run and do the heavy lifting for you. mvn:spring-boot run, and ./gradlew bootRun. — Apurva Singh

I presume you are trying to compile the application and run it without using an IDE. I also presume you have maven installed and correctly added maven to your environment variable.

To install and add maven to environment variable visit Install maven if you are under a proxy check out add proxy to maven

Navigate to the root of the project via command line and execute the command

mvn spring-boot:run

The CLI will run your application on the configured port and you can access it just like you would if you start the app in an IDE.

Note: This will work only if you have maven added to your pom.xml

what do you mean by "the root of the project" if the project is already built in a war archive ?

Adindu Stevens Over a year ago

The root of the the application is the folder that contains the pom.xml of the application is. It one folder backwards from where you found your the .war file.

Michał Ziober Over a year ago

For projects where Spring Boot root POM is not used it does not work and we need to use full name as in this Maven- No plugin found for prefix 'spring-boot' in the current project and in the plugin groups answer.

Andrey M. Stepanov Over a year ago

Does it work "only if you have maven added to your pom.xml" or if you have spring-boot-maven-plugin installed in addition to maven itself? By the way what did you mean exactly by "having maven added to your pom.xml"? How are we supposed to add maven to pom.xml?

Zaphod Beeblebrox Over a year ago

in a multi-module maven project you first have to change to the directory of the application project. When I run "mvn spring-boot:run" in the main folder of my project, I receive an error "no plugin found for prefix 'spring-boot' in the current project..."

You will need to build the jar file first. Here is the syntax to run the main class from a jar file.

java -jar path/to/your/jarfile.jar fully.qualified.package.Application

$ java -jar ./target/springboot-https-seed-1.0-SNAPSHOT.jar ./src/main/java/be/heydari/seed/Application no main manifest attribute, in ./target/springboot-https-seed-1.0-SNAPSHOT.jar

Srikanth Anusuri Over a year ago

@PhilipRego, try you are specifying the path to the java file, not the class. Try this instead java -jar ./target/springboot-https-seed-1.0-SNAPSHOT.jar be.heydari.seed.Application

Gana Over a year ago

You can simplify that command by adding "fully qualified Main class name in pom.xml". Example: <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <archive> <manifest> <mainClass>com.myproject.myapp.Application</mainClass> </manifest> </archive> </configuration> </plugin>

java -jar path/to/your/jarfile.jar (after above pom changes)

If you're using gradle, you can use:

./gradlew bootRun

Assuming only a few users will use the Gradle, the answer is very helpful.

To run the spring-boot application, need to follow some step.

Maven setup (ignore if already setup):

a. Install maven from https://maven.apache.org/download.cgi

b. Unzip maven and keep in C drive (you can keep any location. Path location will be changed accordingly).

c. Set MAVEN_HOME in system variable.

d. Set path for maven

Add Maven Plugin to POM.XML

    <build>
       <plugins>
         <plugin>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-maven-plugin</artifactId>
          </plugin>
        </plugins>
      </build>

Build Spring Boot Project with Maven

    mvn package

or

      mvn install / mvn clean install

Run Spring Boot app using Maven:
```
     mvn spring-boot:run
```

[optional] Run Spring Boot app with java -jar command

      java -jar target/mywebserviceapp-0.0.1-SNAPSHOT.jar

Use mvn package insted of mvn install, mvn install will copy generated file to your local maven repository (.m2) which is not preferred

LakShan Over a year ago

correction:- maven package should be mvn package

1.Run Spring Boot app with java -jar command

To run your Spring Boot app from a command line in a Terminal window you can use java -jar command. This is provided your Spring Boot app was packaged as an executable jar file.

java -jar target/app-0.0.1-SNAPSHOT.jar

2.Run Spring Boot app using Maven

You can also use Maven plugin to run your Spring Boot app. Use the below command to run your Spring Boot app with Maven plugin:

Spring Boot provide the plugin with maven.

So you can go to your project directory and run

mvn spring-boot:run

This command line run will be easily when you're using spring-boot-devs-tool with auto reload/restart when you have changed you application.

For macOS user If you configured your application using maven First, go to your project directory in the terminal then simply run

./mvnw spring-boot:run

You are done. Now you can hit localhost with port number.

This command mentioned in the spring official guide.

One of the ways that you can run your spring-boot application from command line is as follows :

1) First go to your project directory in command line [where is your project located ?]

2) Then in the next step you have to create jar file for that, this can be done as

mvnw package [for WINDOWS OS ] or ./mvnw package [for MAC OS] , this will create jar file for our application.

3) jar file is created in the target sub-directory

4)Now go to target sub directory as jar was created inside of it , i.e cd target

5) Now run the jar file in there. Use command java -jar name.jar [ name is the name of your created jar file.]

and there you go , you are done . Now you can run project in browser,

 http://localhost:port_number

I was having the same problem, I fixed it by modifying the dependency in the pom. I added web at the end.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-**starter**</artifactId>
</dependency>

<dependency>  
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
