Springboot Application exits immediately

Question

When I run my spring boot application , it exits immediately (with exit code 0) with this:

 \\/  ___)| |_)| | | | | || (_| |  ) ) ) )
  '  |____| .__|_| |_|_| |_\__, | / / / /

Solution 1

Because of you spring boot in pom.xml you did not declare as starter web project it will shut down immediately, it is an expected behavior, now to run as web container you need to add below code in your pom.xml.

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

Solution 2

I've just have the problem with IntelliJ (even with the spring-boot-starter-web) and solve it by editing the launcher and check Include dependencies with "Provided" scope option.

The web app was working fine from the command line.

Solution 3

I don't see any issues with this.

Process finished with exit code 0

This says process ended happily.

Given your application is not having spring-boot-starter-web dependency then it won't be starting any server and not waiting for any request.

It is very much similar to a main method which does not have anything to execute or finishes as soon as main code completes.

Solution 4

I just had the same problem. None of the dependencies like spring-boot-starter-web or removing dependency spring-boot-starter-tomcat didn't work. I was using IntelliJ Idea IDE community version. I think it is something to do with the IntelliJ Idea Community Version, as they mention that spring is not supported in the community version, only in the ultimate (commercial) version, at least for mac.

https://www.jetbrains.com/idea/download/#section=mac

The reason of my thinking because I switched to visual studio code, installed the necessary plugins for spring boot and it worked out of the box, with my existing pom.xml file.

My current dependencies are:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
    </dependency>
    <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>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
        <scope>runtime</scope>
        <optional>true</optional>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

May be worth to mention that also works without the spring-boot-starter-tomcat dependency.

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency>. even this doesn't work

[bittu]

ok do you still get the same logs ? Any logs like "tomcat started on port 8080" not coming ?

[bittu]

Very strange. Seems like web dependency is not added to your classpath. Can you just reimport all dependency of your module and restart the application.

[bittu]

Executing maven clean install will reimport all dependency

[Alex78191]

spring-boot-starter-web is needed

[Alex78191]

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

[avdyk]

As I wrote: "event with the spring-boot-starter-web" ;-)

[Kendall Trego]

I had the same problem in intellij, but instead fixed it by right clicking the project -> maven -> reload project after switching the dependencies as described

[Nikolas]

I have spring-boot-started-web dependency, but it is still exit.

[Rag]

Above worked. I had to reimport the project (right click on project root folder -> Maven -> Reimport). It seems to be an issue with IntelliJ possibly detecting early on as standalone desktop project and later properly recognises as web project and initialises Tomcat (binds to the port and waits for connections).

[Mark]

I had this problem also, and I had the spring-boot-starter-web dependency. But I inadvertently excluded the spring-boot-starter-tomcat dependency that web normally brings in, and forgot to add a suitable replacement. My solution was to add spring-boot-starter-jetty.
