JSF集成Spring

 转载:http://blog.csdn.net/Pointer_v/archive/2007/11/08/1874140.aspx

这博客还挺好的嘛，能上传文件，我就传我自己MyEclipse6.0测试通过的例子吧：

      /Files/cshF3220544/JSFSpring.rar

步骤：

 第一步：建立项目

 第二步：配置好JSF，确保JSF程序可运行。

 第三步：配置好Spring，确保Spring可用。

 第四步：下载jsf-spring.jar，到网上很容易找到。

 第五步：修改web.xml:

      1.如果你的Spring还没配置org.springframework.web.context.ContextLoaderListener则首先要配置:

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

      2.配置de.mindmatters.faces.spring.context.ContextLoaderListener

            <listener>
              <listener-class>
                    de.mindmatters.faces.spring.context.ContextLoaderListener
              </listener-class>
            </listener>

      注意：上面两者顺序不能乱。

      3.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>

      否则会报下面的错：

控制台上的错误不太一样
