Quelle est l'erreur de cette démo SpringBoot + SpringCloud + Zookeeper?

Question

J'ai pratiqué une démo en utilisant SpringBoot + SpringCloud + Zookeeper comme site web springboot.Mais une erreur est survenue.

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'zookeeperServiceDiscovery' defined in class path resource [org/springframework/cloud/zookeeper/discovery/ZookeeperDiscoveryClientConfiguration.class]: Unsatisfied dependency expressed through method 'zookeeperServiceDiscovery' parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'instanceSerializer' defined in class path resource [org/springframework/cloud/zookeeper/discovery/ZookeeperDiscoveryClientConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.curator.x.discovery.details.InstanceSerializer]: Factory method 'instanceSerializer' threw exception; nested exception is java.lang.NoClassDefFoundError: org/codehaus/jackson/Versioned

Le pom.xml comme suit:

je peux trouver l'org/Codehaus/jackson/Versioned sur les bibliothèques externes. Pourriez-vous m'aider comment finaliser cela? Pensez-vous!

vous devez ajouter à votre pom:

<dependency> 
    <groupId>org.codehaus.jackson</groupId> 
    <artifactId>jackson-core-asl</artifactId> 
    <version>1.9.13</version> 
</dependency>
