我有几天这个错误，似乎没有运气。尝试谷歌搜索，但仍然无法正常工作。查看日志，它不断告诉我我的 SessionFactory 有问题，但我就是无法理解。UserDao 和 RoleDao 都是我实现的接口。希望收到你们的来信。

错误日志。

您<context:annotation-config/>在您的applicationContext.xml其中没有可以映射到您的sessionFactory. 看起来您要么需要合并这两个配置，要么dispatcher-context.xml在applicationContext.xml.

有同样的问题，无法进行注射。

我的问题是“顺序”。必须首先调用 Hibernate xml。

调度程序-servlet.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.1.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">

<!-- init hibernate first -->
<import resource="classpath:HibernateContext.xml"/>

<bean id="viewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/pages/" />
    <property name="suffix" value=".jsp" />
</bean>
<mvc:annotation-driven />
<context:component-scan base-package="com.xxx.yyy" />
