2023年4月15日 297次阅读

我尝试部署应用程序,但是控制台告诉我这个错误,我不熟悉
Spring MVC和Hibernate 3这是我的第一个项目

 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.MappingException: component class not found: com.GestionEtudiant.model.EtudiantId

EtudiantId类代码是：

package com.GestionEtudiant.model;


    public class EtudiantId implements java.io.Serializable {

        /**
         * 
         */
        private static final long serialVersionUID = 1L;
        private int idPersonne;
        private int idEtudiant;

        public EtudiantId() {
        }

        public EtudiantId(int idPersonne, int idEtudiant) {
            this.idPersonne = idPersonne;
            this.idEtudiant = idEtudiant;
        }

        public int getIdPersonne() {
            return this.idPersonne;
        }

        public void setIdPersonne(int idPersonne) {
            this.idPersonne = idPersonne;
        }

        public int getIdEtudiant() {
            return this.idEtudiant;
        }

        public void setIdEtudiant(int idEtudiant) {
            this.idEtudiant = idEtudiant;
        }

        public boolean equals(Object other) {
            if ((this == other))
                return true;
            if ((other == null))
                return false;
            if (!(other instanceof EtudiantId))
                return false;
            EtudiantId castOther = (EtudiantId) other;

            return (this.getIdPersonne() == castOther.getIdPersonne())
                    && (this.getIdEtudiant() == castOther.getIdEtudiant());
        }

        public int hashCode() {
            int result = 17;

            result = 37 * result + this.getIdPersonne();
            result = 37 * result + this.getIdEtudiant();
            return result;
        }

    }

最佳答案 如果已在EtudiantId.hbm.xml中定义了com.GestionEtudiant.model.EtudiantId的映射

也可以像这样添加到“mappingResources”

 <property name="mappingResources">
        <list>
          ...
           <value>com/GestionEtudiant/model/EtudiantId.hbm.xml</value>
          ...

更新：-

如果您的自动生成的类使用注释,请添加packagesToScan属性,如下所示,

<bean id="sessionFactory"
     <property name="packagesToScan" value="com.GestionEtudiant.model" />
