添加 Undertow 依赖项
我们需要在这里做两件事：-
-
spring-boot-starter-tomcat排除添加的默认依赖项spring-boot-start-web - 添加
spring-boot-starter-undertow依赖。
pom.xml
<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>
build.gradle
dependencies {
implementation('org.springframework.boot:spring-boot-starter-web') {
exclude group: 'org.springframework.boot', module:'spring-boot-starter-tomcat'
}
implementation 'org.springframework.boot:spring-boot-starter-undertow'
}
而已。您已将 tomcat 替换为 Undertow 服务器。
应用程序启动日志
当您启动 Spring Boot 应用程序时，您将在日志中显示 Undertow 现在正在为您的 Web 应用程序提供服务：-
