本文详细介绍了如何在JSF项目中整合Spring框架，包括项目搭建、配置JSF和Spring，以及解决常见错误的方法。

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
