Spring配置如下：

<!-- 注册SessionFactory -->
        <bean id="MySessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
            <property name="dataSource" ref="dataSource"/>
            <!-- 配置映射文件所在文件夹 -->
            <property name="mappingDirectoryLocations" value="classpath:com/hk/beans"/>

            <property name="hibernateProperties">
                <props>
                    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                    <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate5.SpringSessionContext</prop>
                    <prop key="hibernate.hbm2ddl.auto">update</prop>
                    <prop key="hibernate.show_sql">true</prop>
                    <prop key="hibernate.format_sql">true</prop>
                </props>
            </property>
        </bean>

web.xml配置如下：

<filter>
        <filter-name>openSessionInView</filter-name>
        <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>openSessionInView</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

原因：

在源码中可以看到：

public class OpenSessionInViewFilter extends OncePerRequestFilter {

    public static final String DEFAULT_SESSION_FACTORY_BEAN_NAME = "sessionFactory";

    private String sessionFactoryBeanName = DEFAULT_SESSION_FACTORY_BEAN_NAME;


    /**
     * Set the bean name of the SessionFactory to fetch from Spring's
     * root application context. Default is "sessionFactory".
     * @see #DEFAULT_SESSION_FACTORY_BEAN_NAME
     */
    public void setSessionFactoryBeanName(String sessionFactoryBeanName) {
        this.sessionFactoryBeanName = sessionFactoryBeanName;
    }

OpenSessionInViewFilter 中对`SessionFactoryBeanName`有个默认的名字`sessionFactory`，所以如果你的名字不是`sessionFactory`的话就找不到

解决方案：再看一下​​OpenSessionInViewFilter​​源码，发现​​SessionFactoryBeanName​​是一个属性名，同时还提供了set方法，这也就是说我们可以设置自己的​​SessionFactoryBeanName​​——如下：

<filter>
        <filter-name>openSessionInView</filter-name>
        <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class>
        <init-param>
            <param-name>sessionFactoryBeanName</param-name>
            <param-value>MySessionFactory</param-value>
        </init-param>
    </filter>

    <filter-mapping>
        <filter-name>openSessionInView</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
