java - 出现错误：org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: javax/validation/ValidatorFactory

Question

我在 Eclipse 中有一个带有 Hibernate 的项目 Webservice（Tomcat v10.0 et java JDK 8）。当我运行时，出现此错误：“ Servlet.service() for servlet [Jersey Web Application] in context with path [/musichall] throw exception [org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: javax /validation/ValidatorFactory] 与根本原因 java.lang.ClassNotFoundException: javax.validation.ValidatorFactory"

下面是我的 pom.xml

这是我的文件“persistence.xml”

        </properties>
    </persistence-unit>

这是“MusicienService”类


import java.util.ArrayList;
import java.util.List;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.EntityTransaction;
import javax.persistence.Persistence;

import org.restapi.crud.musichall.model.Musicien;

public class MusicienService {
    
            EntityManagerFactory entityManagerFactory = null;
            EntityManager entityManager = null;
          
            public List<Musicien> getAll() throws Exception {
                
                List<Musicien> listMusicien = new ArrayList<>();
                 try {
                        // Call persistence.xml
                        entityManagerFactory = Persistence.createEntityManagerFactory("app-DB"); 
                        entityManager = entityManagerFactory.createEntityManager();
                   
                        System.out.println("List des musiciens");
                        
                        listMusicien = entityManager.createQuery("from Musicien", Musicien.class).getResultList();
                        
                        for (Musicien musicien2 : listMusicien) {
                            System.out.println(musicien2);
                        }
                        
                        return listMusicien;
                    }
                    finally {
                    
                        if (entityManager!=null) { entityManager.close();}
                        if (entityManagerFactory!=null) {entityManagerFactory.close();}
                    }
            }
}

这是“MusicienController”类

package org.restapi.crud.musichall.control;

import java.util.List;

import org.restapi.crud.musichall.model.Musicien;
import org.restapi.crud.musichall.service.MusicienService;

import jakarta.ws.rs.Consumes;

import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.core.MediaType;


@Path ("/musicien")
public class MusicienController {

        @GET
        @Produces(MediaType.TEXT_PLAIN)
        public String getIt() {
            return "Got Musicien!!!!";
        }
    
private MusicienService service = new MusicienService();

    @Path ("/getAllMusiciens")
    @GET  
    @Produces(MediaType.APPLICATION_JSON) 
    public List<Musicien> getAllMusicien () throws Exception {
        return service.getAll();
        
    }
}
