    适己而忘人者,人之所弃;克己而立人者,众之所戴。:解决问题(

    jsf+spring+hibernate整合,于struts+spring+hibernate整合的过程非常相似(就不截图了,可以参考第一篇文章),但是前者相对于后者稍微麻烦一些。

    第一步:初步整合,其过程以及基本配置,于struts+spring+hibernate整合的过程完全一样。

    第二步:要加入jsf-spring.jar(可以到SourceForge上面去下)

    第三步:在web.xml中加入如下listener

    <listener>
    ??<listener-class>
    ???org.springframework.web.context.ContextLoaderListener
    ??</listener-class>
    ?</listener>
    ?<listener>
    ??<listener-class>
    ???de.mindmatters.faces.spring.context.ContextLoaderListener
    ??</listener-class>
    ?</listener>

    二者都要加,而且顺序不能变。

    最好在加入下面的listener顺序没影响

    <listener>
    ??<listener-class>
    ???org.springframework.web.context.request.RequestContextListener
    ??</listener-class>
    ?</listener>

    否则会遇到下面的错误

    控制台上的错误不太一样
