我嘗試部署應用程序，但控制檯向我顯示這個錯誤，我不熟悉Spring MVC和Hibernate 3 this是我的第一個項目org.springframework.beans.factory.BeanCreationException在ServletContext中定義名稱爲'sessionFactory'的bean時出錯
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類代碼爲：

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;
}
}
看：這是一個標準的類路徑問題。用你的XML配置仔細檢查你的類名;他們區分大小寫。 – chrylis
