Hibernate 将库jar整合到spring应用程序中，以定义一个'；sessionFactory'；

问题

我无法在项目中定义正确的

sessionFactory

bean，导致web应用程序初始化失败

日志输出

我使用xml映射和POJO与maven创建了一个ORM库。 我已导入到我的项目中，无法配置以访问DDBB

• jdbc.properties文件使用DDBB连接定义良好（

  db.url

  ，

  db.properties

  ，等等）
• 库中的所有POJO都扩展了HibernateDaoSupport并实现了基本操作接口（CRUD）。我正在使用一个扩展DaoBase的服务webServiceTest来进行测试
• 我在ORM库中进行了JUnit测试，结果很好

以下是appcontext-persistence.xml文件中的

dataSource

、

sessionFactory

等定义：

${db.driver}
${db.url}
${db.username}
${db.password}
${db.maxActive}
${db.maxIdle}
${db.maxWait}
真的
真的
11
真的
org.hibernate.dial.Oracle9iDialect
真的

问题:

• Spring配置必须从ORM jar加载hibernate.cfg.xml？我该怎么做
• 如何将配置从Spring ORM项目加载到另一个项目中
• 我在ORM中定义了映射，但我没有在ORM中定义任何要包含在jar中的应用程序上下文

我已经使用beans标签的属性

default autowire=“byName”

解决了这个问题，它加载了appcontext-spring.xml中需要的对象注入的所有配置

---

并创建sessionFactory。

我已经使用bean标记“default autowire=“byName”的属性解决了这个问题，它加载了所有需要的对象注入配置。autowire实例化了所有需要的bean以创建数据库连接
