Spring: Developing Java Applications for the Enterprise

Changing the default embedded web server

Embedded HTTP listeners can easily be customized as follows. By default, Spring Boot supports Tomcat, Jetty, and Undertow. In the following example, Tomcat is replaced with Undertow:

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