Question

我正尝试使用Java代码读取yaml文件内容，但无法使用Java模型类构造Java对象

请找到我的person.yaml文件

name: Joe
phone: 111-111-11111
address: Park Dr, Charlie Hill

请找到我的模特班

public class Person {

      private String name;
      private String phone;
      private String address;

}

请找到我的服务方法：

public class PersonsService {

    public static void main(String args[]) throws IOException {

         Yaml yaml = new Yaml();
          try (InputStream in = PersonsService.class
                  .getResourceAsStream("person.yaml")) {
              Person person = yaml.loadAs(in, Person.class);
              System.out.println(person);
          }

    }

}

我收到以下错误：

Exception in thread "main" Can't construct a java object for tag:yaml.org,2002:com.javaproject.snakeyaml.model.Person; exception=Cannot create property=name for JavaBean=com.javaproject.snakeyaml.model.Person@77a567e1; No JavaBean properties found in com.javaproject.snakeyaml.model.Person

错误说明了所有问题：

无法为tag：yaml.org，2002：com.javaproject.snakeyaml.model.PersoN构造Java对象...在com.javaproject.snakeyaml.model.Person中找不到JavaBean属性

因此，您必须为pipeline { agent { label "dockercon2"} stages { stage('checkout_stage'){ steps { sh "id && whoami" checkout([$class: 'GitSCM', branches: [[name: "*/${env.SOURCE_BRANCH}"]], doGenerateSubmoduleConfigurations: false, extensions: [[$class: 'CleanBeforeCheckout'], [$class: 'PerBuildTag'], [$class: 'IgnoreNotifyCommit'], [$class: 'PreBuildMerge', options: [mergeRemote: 'origin', mergeTarget: "${gitTargetbranch()}"]]], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'https_gitlab_clone_credential', name: 'origin', refspec: '+refs/heads/testing_pipeline:refs/remotes/origin/testing_pipeline', url: "${gitUrl()}"]]]) git branch: "${gitSourcebranch()}", credentialsId: 'https_gitlab_clone_credential', url: "${gitUrl()}" withCredentials([usernamePassword(credentialsId: 'https_gitlab_clone_credential', passwordVariable: 'bb_pass', usernameVariable: 'bb_user')]) { sh "figlet 'wazzup'" sh "figlet 'i am on'" sh "git config credential.username ${UserName()}" sh "git config credential.helper ${Gitlab_Pass()}" //sh "git config --global user.email ${UserEmail()}" sh "git config --global user.name ${UserName()}" //sh "set +x /bin/sh -c \"echo ${ansibleVaultCredentials()}>vault_passwd.txt\"" sh "set +x; echo ${ansibleVaultCredentials()} >> vault_passwd.txt" sh "echo pass" sh "cat vault_passwd.txt" sh "ansible-vault decrypt --vault-password-file vault_passwd.txt test.sh && sh test.sh" }// closing withCredential }// steps of checkout_stage }// EDITED: Closing the checkout_stage block stage('creating_PR') { steps { when { step (currentBuild.result == "SUCCESS") } triggers { bitbucketServer(bitbucketpr(projectPath: "${gitUrl()}", cron:'H/15 * * * *', credentialsId:'bitbucket_glone_cred', username:"${bb_user}", password:"${bb_pass}", repositoryOwner:'Atul', repositoryName:'valutstorage', branchesFilter:"${gitSourcebranch()}", branchesFilterBySCMIncludes:false, ciKey:'jenkins', ciName:'jenkins', ciSkipPhrases:'', checkDestinationCommit:false, approveIfSuccess:false, cancelOutdatedJobs:true, commentTrigger:'')) } } } } // Main stages block closer } // Pipeline closer类提供getter和setter，以便库将使用它们来为Person类对象设置值。可以在here中找到有关JavaBeans属性的更多信息。

无法为tag：yaml.org，2002
