SSH整合 出现 No bean named ‘MysessionFactory’ is defined

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>
