OpenSessionInViewFilter不能转换为javax.servlet.Filter

当我尝试在Tomcat7中启动Java EE Spring + Hibernate应用程序时出现异常。这用于工作，但我认为我在迁移到Tomcat7时搞砸了一些东西。唯一的例外是OpenSessionInViewFilter不能转换为javax.servlet.Filter

我所有的春瓶是3.1.3.RELEASE，我有以下两个Hibernate依赖：

<dependency>

     <artifactId>hibernate-core</artifactId> 
     <version>3.6.8.Final</version> 
    </dependency> 
    <dependency> 
     <groupId>org.hibernate</groupId> 
     <artifactId>hibernate-validator</artifactId> 
     <version>4.3.0.Final</version> 
    </dependency>

我“提供“一些标准JEE罐子：

<dependency> 
     <groupId>javax.servlet</groupId> 
     <artifactId>jstl</artifactId> 
     <version>1.2</version> 
     <scope>provided</scope> 
    </dependency> 

    <dependency> 
     <groupId>javax.servlet</groupId> 
     <artifactId>javax.servlet-api</artifactId> 
     <version>3.0.1</version> 
     <scope>provided</scope> 
    </dependency>

下面是从mvn dependency:tree输出：

任何想法，为什么我得到这个例外？

听起来像你在WEB-INF/lib有一个版本的servlet API。如果您使用的是maven，请查找违规依赖项，并确保将其依赖项排除在servlet-api上。 mvn dependency:tree的输出可能有助于追踪不需要的传递依赖。

编辑：

如果一切似乎是正确的，而你仍然遇到这个问题，一个技术我用它来找出一类是从加载是这样的：

Filter.class.getProtectionDomain().getCodeSource().getLocation()

它会给你该类所在的jar /文件夹的位置。我还建议您尝试将您的Web应用程序部署在独立应用程序服务器中，以排除IDE（例如服务器/部署插件）作为问题的根源。

我不认为我理解。 OpenSessionInViewFilter是一个过滤器。我相信它应该依赖于javax.servlet.Filter类。 – Marvo

是的，但'servlet-api'由应用程序服务器提供，不应位于单个Web应用程序的'WEB-INF/lib'中。因此，如果您使用的是maven，请确保servlet-api依赖项具有“提供”范围。 – NilsH

我添加了一些额外的依赖关系到我原来的问题，他们确实标记为“提供”。也就是说，我在Eclipse的服务器部署目录中找到了servlet-api jar。我删除它，仍然得到相同的错误。也许它正在采用其他一些过滤器类，这就是为什么它抱怨？（感谢您的洞察力。） – Marvo
