我正在尝试创建一个Gradle项目来注册Eureka服务。主要方法配置：

代码语言：javascript
复制
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaServerApplication.class, args);
    }

}

我使用这种分级配置：

代码语言：javascript
复制
plugins {
    id 'org.springframework.boot' version '2.4.5'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'org.test'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

repositories {
    mavenCentral()
}

dependencies {
    implementation group: 'org.springframework.cloud', name: 'spring-cloud-starter-netflix-eureka-client', version: '3.0.2'
    implementation group: 'org.springframework.cloud', name: 'spring-cloud-netflix-eureka-server', version: '3.0.2'
}

test {
    useJUnitPlatform()
}

但是，当我编译该项目时，我会得到以下错误：

APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.apache.catalina.authenticator.AuthenticatorBase.startInternal(AuthenticatorBase.java:1355)

The following method did not exist:

    'java.lang.String javax.servlet.ServletContext.getVirtualServerName()'

The method's class, javax.servlet.ServletContext, is available from the following locations:

    jar:file:/C:/Users/plte1219/Desktop/CJM/skyshop-registry/build/libs/server-0.0.1-SNAPSHOT.jar!/BOOT-INF/lib/servlet-api-2.5.jar!/javax/servlet/ServletContext.class
    jar:file:/C:/Users/plte1219/Desktop/CJM/skyshop-registry/build/libs/server-0.0.1-SNAPSHOT.jar!/BOOT-INF/lib/tomcat-embed-core-9.0.45.jar!/javax/servlet/ServletContext.class

The class hierarchy was loaded from the following locations:

    javax.servlet.ServletContext: jar:file:/C:/Users/plte1219/Desktop/CJM/skyshop-registry/build/libs/server-0.0.1-SNAPSHOT.jar!/BOOT-INF/lib/servlet-api-2.5.jar!/


Action:

Correct the classpath of your application so that it contains a single, compatible version of javax.servlet.ServletContext

你知道我怎样才能解决这个问题吗？

更正应用程序的类路径，以便它包含一个兼容的javax.servlet.ServletContext版本。

spring-cloud-starter-netflix-eureka-client包含可能与其他组件冲突的servlet-api。

可以排除这一点(对于maven)：
