Java 没有名为'的bean；sessionFactory'；在OpenSessionInViewFilter之后定义

因为LazyInitializationException，我需要在我的web.xml中添加“OpenSessionViewInfiller”，代码如下：

<!--  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>

我不知道为什么会发生此错误，因为我使用的是Entitymanager（JPA）而不是SessionFactory，请参阅我的applicationContext.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

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>

OpenEntityManager视图过滤器
org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter

及

OpenEntityManager视图过滤器
/*

然后，您需要将spring orm-{our version here}.jar添加到您的类路径中。如果你用的是maven

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

org.springframework
春季甲虫
${spring.ver}

抱歉，我使用的是JPA，您的代码表明您使用的是hibernate3，因此您的筛选器类应该是org.springframework.orm.hibernate3.support.OpenSessionInViewFilter

，谢谢您的帮助。此OpenEntityManagerViewFilter特定于JPA，另一个特定于HIBERNATE？@Mr.Lanhellas请检查我上面的编辑：）我在hibernate中也使用JPA，但在EntityManager中使用。@Mr.Lanhellas我在hibernate实现中使用JPA，我的第一个代码片段应该适合您。：）我尝试过，但我有另一个问题：在登录应用程序后，当我尝试调用lazy属性时，我遇到了LazyInitializationException（会话已关闭）。

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

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