我有一个查询,我碰巧有一个名为“ SGOrdCompra”的表,该表将他与“ SGPersona”链接了两次,如下表:
Sgordcompra.java
@Entity
@Table(name = "`SGOrdCompra`", schema = "`public`")
public class Sgordcompra implements java.io.Serializable {
.....
private Sgpersona sgpersonaByIcodSolicitante;
private Sgpersona sgpersonaByIcodComprador;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "`iCodSolicitante`", nullable = false)
public Sgpersona getSgpersonaByIcodSolicitante() {
return this.sgpersonaByIcodSolicitante;
}
public void setSgpersonaByIcodSolicitante(
Sgpersona sgpersonaByIcodSolicitante) {
this.sgpersonaByIcodSolicitante = sgpersonaByIcodSolicitante;
}
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "`iCodComprador`", nullable = false)
public Sgpersona getSgpersonaByIcodComprador() {
return this.sgpersonaByIcodComprador;
}
public void setSgpersonaByIcodComprador(Sgpersona sgpersonaByIcodComprador) {
this.sgpersonaByIcodComprador = sgpersonaByIcodComprador;
}
}
Sgpersona.java
@Entity
@Table(name = "`SGPersona`", schema = "`public`")
public class Sgpersona implements java.io.Serializable {
private static final long serialVersionUID = 1L;
private int icodPersona;
private Set<Sgrencajchica> sgrencajchicas = new HashSet<Sgrencajchica>(0);
....
private Set<Sgordcompra> sgordcomprasForIcodComprador = new HashSet<Sgordcompra>(0);
private Set<Sgordcompra> sgordcomprasForIcodSolicitante = new HashSet<Sgordcompra>(0);
@OneToMany(fetch = FetchType.LAZY, mappedBy = "sgpersona")
public Set<Sgrencajchica> getSgrencajchicas() {
return this.sgrencajchicas;
}
public void setSgrencajchicas(Set<Sgrencajchica> sgrencajchicas) {
this.sgrencajchicas = sgrencajchicas;
}
.......
@OneToMany(fetch = FetchType.LAZY, mappedBy = "sgpersona")
public Set<Sgordcompra> getSgordcomprasForIcodComprador() {
return this.sgordcomprasForIcodComprador;
}
public void setSgordcomprasForIcodComprador(
Set<Sgordcompra> sgordcomprasForIcodComprador) {
this.sgordcomprasForIcodComprador = sgordcomprasForIcodComprador;
}
@OneToMany(fetch = FetchType.LAZY, mappedBy = "sgpersona")
public Set<Sgordcompra> getSgordcomprasForIcodSolicitante() {
return this.sgordcomprasForIcodSolicitante;
}
public void setSgordcomprasForIcodSolicitante(
Set<Sgordcompra> sgordcomprasForIcodSolicitante) {
this.sgordcomprasForIcodSolicitante = sgordcomprasForIcodSolicitante;
}
}
我收到此错误:
ERROR: org.springframework.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'iGenericDao': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.hibernate.SessionFactory org.sgkyros.common.dao.impl.GenericDaoImpl.sessionFactory; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/application-context.xml]: Invocation of init method failed; nested exception is org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: org.sgkyros.common.entity.Sgordcompra.sgpersona in org.sgkyros.common.entity.Sgpersona.sgordcomprasForIcodComprador
但是,如果我注释与“ Sgpersona”类相关的代码行,请对其进行测试,这对我来说通常是正常的,应该是...吗?
private Set<Sgordcompra> sgordcomprasForIcodComprador = new HashSet<Sgordcompra>(0);
private Set<Sgordcompra> sgordcomprasForIcodSolicitante = new HashSet<Sgordcompra>(0);
最佳答案
mappingBy属性试图在类“ Sgordcompra”中引用无效的属性“ sgpersona”。 OneToMany映射应按以下方式进行:
@OneToMany(fetch = FetchType.LAZY, mappedBy = "sgpersonaByIcodComprador")
public Set<Sgordcompra> getSgordcomprasForIcodComprador() {
return this.sgordcomprasForIcodComprador;
}
@OneToMany(fetch = FetchType.LAZY, mappedBy = "sgpersonaByIcodSolicitante")
public Set<Sgordcompra> getSgordcomprasForIcodSolicitante() {
return this.sgordcomprasForIcodSolicitante;
}
