70.13 使用Undertow替代Tomcat

使用Undertow替代Tomcat和使用Jetty替代Tomcat非常类似。你需要排除Tomat依赖，并包含Undertow starter。

Maven示例：

<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")
    // ...
}
