本文介绍了一次在CRM系统中遇到的Hibernate一对多双向关联异常的问题及解决过程。异常源于Contact实体类中Customerinfo属性的getter和setter方法名称错误导致。通过调试和修改方法名最终解决了这个问题。

1,今天做公司的CRM客户关系管理软件：其中客户和联系人采用了Hibernate的一对多双向关联的关系。发生了如下异常： org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loggerListener' defined in ServletContext resource [/WEB-INF/security.xml]: BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.transaction.config.internalTransactionAdvisor': Cannot create inner bean '(inner bean)' of type [org.springframework.transaction.interceptor.TransactionInterceptor] while setting bean property 'transactionInterceptor'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#1': Cannot resolve reference to bean 'transactionManager' while setting bean property 'transactionManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in ServletContext resource [/WEB-INF/applicationContext-dao.xml]: Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext-dao.xml]: Invocation of init method failed; nested exception is org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: com.ynstudio.crm.model.Contact.customerinfo in com.ynstudio.crm.model.Customerinfo.contacts后几番调试后，终于发现。原来是Contact的

/**     *所属客户       */  
 @ManyToOne(fetch=FetchType.EAGER)    
@JoinColumn(name="CUSTOMER_ID", unique=true, nullable=true)//, insertable=false, updatable=false) 
 public Customerinfo getCustomer() {  
      return customerinfo;    
}   
public void setCustomer(Customerinfo customerinfo) {        
this.customerinfo = customerinfo;    
}

解释下这里为什么会犯这种低级错:因为这段代码是我拷贝过来的，Customerinfo的get和set方法还没换过来。改为

public Customerinfo getCustomerinfo() {       
return customerinfo;   
} 
public void setCustomerinfo(Customerinfo customerinfo) {       
this.customerinfo = customerinfo;   
}
