# 70.13 使用Undertow替代Tomcat

使用Undertow替代Tomcat和[使用Jetty替代Tomcat](https://github.com/cwiki-us-spring-guides/Spring-Boot-Reference-Guide/tree/0047aa8098a650dde0c93f4d2e91754c83468c4b/IX.%20%E2%80%98How-to%E2%80%99%20guides/70.11%20Use%20Jetty%20instead%20of%20Tomcat.md)非常类似。你需要排除Tomat依赖，并包含Undertow starter。

Maven示例：

```markup
<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>
```

Gradle示例：

```
configurations {
    compile.exclude module: "spring-boot-starter-tomcat"
}

dependencies {
    compile 'org.springframework.boot:spring-boot-starter-web:1.3.0.BUILD-SNAPSHOT")
    compile 'org.springframework.boot:spring-boot-starter-undertow:1.3.0.BUILD-SNAPSHOT")
    // ...
}
```
