dubbo使用zookeeper端口占用问题和依赖问题

• 问题一：

Failed to start bean 'webServerStartStop'; nested exception is java.lang.NoClassDefFoundError: org/eclipse/jetty/webapp/WebAppContext

• 依赖问题说什么无法开始

<dependency>  
    <groupId>org.apache.dubbo</groupId>  
    <artifactId>dubbo-spring-boot-starter</artifactId>  
    <version>${dubbo.version}</version>  
</dependency>  
<dependency>  
    <groupId>org.apache.dubbo</groupId>  
    <artifactId>dubbo-dependencies-zookeeper-curator5</artifactId>  
    <version>${dubbo.version}</version>  
    <type>pom</type>  
    <exclusions>        
        <exclusion>  
            <artifactId>slf4j-reload4j</artifactId>  
            <groupId>org.slf4j</groupId>  
        </exclusion>  
    </exclusions>  
</dependency>  
<dependency>  
    <groupId>org.eclipse.jetty</groupId>  
    <artifactId>jetty-webapp</artifactId>  
    <version>9.4.49.v20220914</version>  
</dependency>

• 问题二：

Address already in use: bind
......
No provider available., dubbo version: 3.2.0

• 端口问题，说什么端口问题，这里直接看官方文档

dubbo:  
  application:  
    name: dubbo-springboot-demo-consumer  
    qos-enable: true  
    qos-port: 33333  
    qos-accept-foreign-ip: false  
  protocol:  
    name: dubbo  
    port: -1  
  registry:  
    address: zookeeper://${zookeeper.address:192.168.137.1}:2181
