好吧，因为 LazyInitializationException 我需要在我的 web.xml 中添加“OpenSessionViewInFilter”，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>

问题是在我添加这段代码后，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个错误，因为我使用的是 Entitymanager (JPA) 而不是 SessionFactory，请查看我的 applicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>

最佳答案

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>

然后您需要将spring-orm-{我们的版本在这里}.jar 添加到您的类路径中。如果你使用 maven，就像这样

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

抱歉，我正在使用 JPA，您的代码表明您正在使用 hibernate3，因此您的过滤器类应该是 org.springframework.orm.hibernate3.support.OpenSessionInViewFilter

关于java - 在 OpenSessionInViewFilter 之后没有定义名为 'sessionFactory' 的 bean，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22702851/
