获取错误bean类[..]的属性'packagesToScan'无效。 Bean属性“packagesToScan”不可写无效或者和setter方法

我收到以下错误获取错误bean类[..]的属性'packagesToScan'无效。 Bean属性“packagesToScan”不可写无效或者和setter方法

Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'packagesToScan' of bean class[org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]: Bean property 'packagesToScan' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?\

我使用spring3.2。使用MAven添加依赖项。一切似乎都好。为什么我得到这个错误。下面是我的文件

不知道你packagesToScan？希望你使用注释，如@Table, @Entity, @column ... 你不需要扫描任何软件包。时，你会尝试CRUD的实体，Hibernate会读注释我的回答是只删除了这一行

UPDATE config.dao.xml

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
    <property name="persistenceXmlLocation" value="classpath:./META-INF/persistence.xml" /> 
    <property name="dataSource" ref="dataSource" /> 

    <property name="jpaVendorAdapter"> 
     <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> 
      <property name="databasePlatform" value="org.hibernate.dialect.H2Dialect" /> 
      <property name="showSql" value="true" /> 
      <property name="generateDdl" value="false" /> 
     </bean> 
    </property> 
    <property name="jpaProperties"> 
     <props> 
      <prop key="hibernate.max_fetch_depth">3</prop> 
      <prop key="hibernate.jdbc.fetch_size">50</prop> 
      <prop key="hibernate.jdbc.batch_size">10</prop> 
     </props> 
    </property> 
</bean>

persitence.xml

没有，如果我删除行，然后我得到的错误'错误创建在类路径资源定义名称“EMF”豆[数据源-TX-jpa.xml]：init方法的调用失败;嵌套异常是java.lang.IllegalStateException：没有持久化单元从{classpath *：META-INF/persistence.xml}解析' – Basit

创建一个persitence.xml，在META-INF中，我会给你一个样例 –

谢谢。我试过，但现在我得到以下异常'产生的原因：org.springframework.beans.factory.BeanCreationException：错误创建在类路径资源[数据源-TX-jpa.xml]定义的名称“EMF”豆：初始化的调用方法失败;嵌套异常是java.lang.AbstractMethodError：org.springframework.orm.jpa.persistenceunit.SpringPersistenceUnitInfo.getSharedCacheMode（）Ljavax /持久/ SharedCacheMode;' – Basit

我已经解决了这个问题。其实我认为我的POM不正确。我正在制作Spring MVC项目，首先我的POM如下图所示。我认为使用这个POM我有很多jar冲突，因为maven使用传递方法来下载jar。

纵观Spring 3.2.3的源码，我注意到其实getPackagesToScan()在org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean的方法中没有，所以，BeanUtils是正确的启动这个异常！

获取错误bean类[..]的属性'packagesToScan'无效。 Bean属性“packagesToScan”不可写无效或者和setter方法
