java – 在OpenSessionInViewFilter之后没有定义名为’sessionFactory’的bean

好吧,因为LazyInitializationException我需要在我的web.xml中添加“OpenSessionViewInFilter”,使用以下代码：

<!--  openSessionInViewfilter -->
 <filter>  
        <filter-name>openSessionInViewFilter</filter-name>  
        <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>  
    </filter>  
 
    <filter-mapping>  
        <filter-name>openSessionInViewFilter</filter-name>  
        <url-pattern>/*</url-pattern>  
    </filter-mapping>

问题是在我添加此代码后,当我尝试启动TOMCAT 7时出现以下错误：

我不知道为什么会出现这种错误,因为我使用的是Entitymanager(JPA)而不是SessionFactory,请参阅我的applicationContext.xml：

    </bean>

解决方法

您需要在下面添加两个代码段

<filter>
    <filter-name>OpenEntityManagerInViewFilter</filter-name>
    <filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class>
</filter>

和

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

然后你需要在你的类路径中添加spring-orm- {我们的版本} .jar.如果你使用maven就像这样

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-orm</artifactId>
    <version>${spring.ver}</version>
</dependency>

– 编辑 –

对不起,我正在使用JPA,你的代码建议你使用hibernate3,所以你的filter-class应该是org.springframework.orm.hibernate3.support.OpenSessionInViewFilter

java – 在OpenSessionInViewFilter之后没有定义名为’sessionFactory’的bean
