创建名称为 'sessionFactory' 的 bean 在 ServletContext 资源 [/WEB-INF/spring-mvc-crud-demo-servlet.xml] 中定义时出错

Question

我是 spring mvc 的新手，遇到会话工厂的这个问题 "Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/spring-mvc-crud-demo-servlet.xml]"

我已将所有必需的 jar 添加到 class 路径，但它仍然存在

这是我的 spring-mvc-crud-demo-servlet.xml 文件

这是我的 web.xml 文件：

<!DOCTYPE xml>
<web-app>
<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>

</servlet>

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>

Answer 1

<prop key="hibernate.dialect">org.hibernate.dialect.mySQLDialect</prop>

必须

<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>

这里你引用了一个class，这是区分大小写的。所以 my 必须是 My 大写 M
