How can we exclude embedded Tomcat server from Spring Boot application so that we can run that jar on JBoss Server?

    You don't need to exclude it it will just run on the server AND be executable. – M. Deinum Dec 15 '17 at 07:23
  • Okay, that means even if we run jar on production server, in our case we are using Jboss on prod,will automatically deploy on jboss instead of Tomcat? – Deepesh Rathore Dec 15 '17 at 07:26

    I was assuming a `war` file and not a `jar` file. You should at least make the dependencies scoped `provided` so that they are moved to a different directory. That directory is used by Spring Boot but not when deploying the file. – M. Deinum Dec 15 '17 at 07:27
  • Incase of jar file what it gonna do, will it deploy on embedded Tomcat or ll it deploy on jboss. – Deepesh Rathore Dec 15 '17 at 07:28

You can exclude in pom file:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>
            <artifactId>tomcat-embed-el</artifactId>
            <groupId>org.apache.tomcat.embed</groupId>
        </exclusion>
        <exclusion>
            <artifactId>tomcat-embed-core</artifactId>
            <groupId>org.apache.tomcat.embed</groupId>
        </exclusion>
        <exclusion>
            <artifactId>tomcat-embed-websocket</artifactId>
            <groupId>org.apache.tomcat.embed</groupId>
        </exclusion>
    </exclusions>
</dependency>

you can modify your POM.xml file as follows:

  <!-- Removing the dependency for the embedded tomcat -->
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
                <exclusions>
                    <exclusion>
                        <groupId>org.springframework.boot</groupId>
                        <artifactId>spring-boot-starter-tomcat</artifactId>
                    </exclusion>
                </exclusions>

Another way is to mark the tomcat dependency's scope as provided in your pom.xml:

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

    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-websocket</artifactId>
        <scope>provided</scope>
    </dependency>

    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-core</artifactId>
        <scope>provided</scope>
    </dependency>

Add the <exclusions> tag in dependency with <artificatId> as 'spring-boot-starter-web'

<exclusions>
    <exclusion>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-tomcat</artifactId>
    </exclusion>
</exclusions>

Your final dependency should look like:

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-tomcat</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
</dependencies>

Better to mention

scope as provided in pom.xml file

to exclude embedded tomcat server in spring boot maven based application.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>
