找不到Hibernate属性，但Spring-MVC不需要

时间：2014-09-08 11:41:05

标签： spring hibernate spring-mvc

我正在开发一个maven项目，该项目直接使用Spring-MVC连接hibernate和hibernate方言，并在servlet中指定其他信息。我正在使用POSTGRES。我有两个问题，我是否必须创建一个供应用程序使用的数据库？根据我的阅读，当直接使用Spring-MVC和hibernate时，没有必要有一个单独的hibernate.properties文件，但我仍然有错误。我发布了错误代码和servlet文件。请告诉我。谢谢。

请告诉我应该怎么做。谢谢。

2 个答案:

答案 0 :(得分：2)

Hibernate只是尝试在初始化期间加载hibernate.properties文件，如果该文件不存在，则会显示一条消息，说明该文件不可用。

INFO : org.hibernate.cfg.Environment - HHH000206: hibernate.properties not found

这只是一个记录器INFO消息而不是ERROR

<强>更新

第二个堆栈跟踪只是说这些类在运行时不可用，因此在部署应用程序时检查是否正确包含了类。

java.lang.ClassNotFoundException: com.journaldev.spring.dao.PersonDAOImpl

java.lang.ClassNotFoundException: com.journaldev.spring.service.PersonServiceImpl

同样从第一个堆栈跟踪开始，您似乎没有放置包含Driver类的jar文件，这是错误，表示Diver类缺失：

WARN : org.hibernate.engine.jdbc.internal.JdbcServicesImpl - HHH000342: Could not obtain connection to query metadata : Cannot load JDBC driver class 'org.postgresql.Driver'
INFO : org.hibernate.dialect.Dialect - HHH000400: Using dialect: org.hibernate.dialect.MySQLDialect

答案 1 :(得分：0)

查看您在问题中添加的日志，这看起来更像是类加载问题。 Spring正在尝试使用PersonDAOImpl初始化bean，因为您已在上下文文件中定义但无法找到该类。

请确保该类可用，可能是它的一个独立jar的一部分，并且该jar在运行时不存在。
