在ServletContext资源中定义名为'hibernate4AnnotatedSessionFactory'的bean时出错-Java 学习之路

我开始学习JSF了，我用hibernate和spring配置了它 . Tomcat不抛出“在ServletContext资源中定义名为'hibernate4AnnotatedSessionFactory'的bean创建错误错误”

这是我的appContext.xml：

http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans .xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http：/ /www.springframework.org/schema/tx/spring-tx-4.0.xsd“>

<resources mapping="/resources/**" location="/resources/" />

private static final Logger logger = LoggerFactory.getLogger(UsersDAOImpl.class);

@Autowired
private SessionFactory sessionFactory;

public void setSessionFactory(SessionFactory sessionFactory) {
    this.sessionFactory = sessionFactory;
}

@Override
public void addUser(Users s) {
    Session session= this.sessionFactory.getCurrentSession();
    session.persist(s);
logger.info("User saved successfully, User details" + " " + s); 

}
@SuppressWarnings("unchecked")
@Override

    Session session = this.sessionFactory.getCurrentSession();
    List<Users> usersList = session.createQuery("FROM Users").list();
    for (Users u : usersList) {
        logger.info("Users list" + " " +u);
    }
    return usersList;
}

}

正如你在日志中看到的那样

嵌套异常是org.hibernate.AnnotationException：没有为entity：users.Users指定标识符

所以最有可能的是你错过了一个用_Id注释 Users 实体的字段 .
