Question

我开始了我的新的Spring mvc项目，我决定使用SpringSource ToolSuite。当我创建一个项目时，它会自动在我的web.xml中创建urlrewrite过滤器，我非常喜欢它。然而，这个精彩的urlrewrite东西似乎不适用于opensessioninviewfilter。有人可以帮助我吗？

这是我的web.xml（我尝试通过更改过滤器的顺序。）

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/app-config.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- sessiong neelttei bailgah tohirgoo -->
    <filter>
      <filter-name>hibernateFilter</filter-name>
      <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
      <init-param>
         <param-name>sessionFactoryBeanName</param-name>
         <param-value>sessionFactory</param-value>         
      </init-param>      
   </filter>

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

    <!-- Enables clean URLs with JSP views e.g. /welcome instead of /app/welcome -->
    <filter>
        <filter-name>UrlRewriteFilter</filter-name>
        <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
    </filter>

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

    <!-- Handles all requests into the application -->
    <servlet>
        <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                /WEB-INF/spring/*.xml
            </param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <!-- Maps all /app requests to the DispatcherServlet for handling -->
    <servlet-mapping>
        <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
        <url-pattern>/app/*</url-pattern>
    </servlet-mapping>



</web-app>

Answer 1

我对OpenSessionInViewFilter知之甚少，但它可能没有链接，在这种情况下，完成后不会再调用过滤器。

Answer 2

这件事确实发生在我身上，而axtavt对here提出的解决方案对于不同的过滤器也是有效的。

只需声明您的OpenSessionInViewFilter过滤器映射，如下所示：

<filter-mapping>
    <filter-name>
        OpenPersistenceManagerInViewFilter
    </filter-name>
    <url-pattern>/app/*</url-pattern>
    <url-pattern>/api/*</url-pattern>
    <url-pattern>/admin/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
</filter-mapping>

只是为了帮助关键字加载，当您尝试使用JDO访问Google App Engine上的数据存储区时，此错误就会显现：

org.datanucleus.exceptions.NucleusUserException: Object Manager has been closed

urlrewrite和opensessioninviewfilter无法一起使用
