Tomcat没有部署该应用程序。它说

失败 - 在上下文路径/ CasaDiscografica2部署应用程序但是上下文无法启动

并告诉我错误：

org.springframework.beans.factory.BeanCreationException：创建名称为＆＃39; albumDao＆＃39;的bean时出错在ServletContext资源[/WEB-INF/applicationContext.xml]中定义：设置属性值时出错;嵌套异常是org.springframework.beans.NotWritablePropertyException：无效的属性＆＃39; sessionFactory＆＃39; bean类

和

org.springframework.beans.NotWritablePropertyException：无效的属性＆＃39; sessionFactory＆＃39; bean类[it.davidefruci.casadiscografica2.daoImpl.AlbumDaoImpl]：Bean属性＆＃39; sessionFactory＆＃39;不可写或具有无效的setter方法。 setter的参数类型是否与getter的返回类型匹配？

为什么呢？感谢。

Answer 1

如果您要自动装配SessionFactory，则无需在上下文中明确注入它。

如果您希望自动装配工作，请不要忘记将<context:annotation-config />添加到您的应用程序上下文中。
