Question

我正在使用Spring 3.1.1.RELEASE和4.0.1.Final并读取我必须避免使用HibernateTemplate。我没有在网上找到一个完整的例子，所以我写了这段代码，但是没有用。

Dao班

@Repository("userDao")
public class UserDaoImpl implements UserDao {

    @Autowired
    private SessionFactory sessionFactory;

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

Spring Config

    <bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource">
                <ref bean="dataSource" />
        </property>
        ...
    </bean>

但抛出异常：我认为这是正常的，因为sessionFactory它不是LocalSessionFactoryBean，但我不知道如何解决它。

Could not autowire field: private org.hibernate.SessionFactory com.test.dao.impl.UserDaoImpl.sessionFactory; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

遇到同样的问题，无法进行注射工作。

我的问题是“序列”。必须首先调用Hibernate xml。

调度-servlet.xml中：

<?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" />

从没有HibernateTemplate的LocalSessionFactoryBean获取SessionFactory
