名爲「SessionFactory的」無豆是的OpenSessionInViewFilter

Question

好之後確定，因爲LazyInitializationException中，我需要添加「OpenSessionViewInFilter」在我的web.xml中，用下面的代碼：

<!-- 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> 

問題是我加入此之後代碼中，我得到了以下錯誤，當我嘗試啓動Tomcat 7：

我不知道，知道爲什麼這個錯誤occurrs因爲我使用的EntityManager（JPA），而不是SessionFactory的，看到我的applicationContext.xml：

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

</beans> 

Answer 1

你需要下面

<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> 

添加這兩個片段然後，你需要彈簧orm- {我們在這裏的版本}的.jar添加到類路徑。像這樣的，如果你使用maven

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

對不起，我使用JPA，您的代碼建議你使用Hibernate3的讓你的過濾器類應該是org.springframework .orm.hibernate3.support.OpenSessionInViewFilter
