我开始了我的新Spring mvc项目,并决定使用SpringSource ToolSuite。当我创建一个项目时,它会在我的web.xml中自动创建urlrewrite过滤器,我对此非常满意。但是,这种出色的urlrewrite功能似乎不适用于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"

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

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

    <!-- Handles all requests into the application -->
    <servlet>

        </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>

最佳答案

这件事发生在我身上,axtavt在here上针对另一种过滤器提出的解决方案也对此有所帮助。

只需像这样声明您的OpenSessionInViewFilter过滤器映射:

<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>


仅在关键字加载以防万一的情况下,当您尝试使用JDO访问Google App Engine上的数据存储时,此错误就会显现:
