Liferay 和 JSF2 + Spring 集成

Question

我使用 Eclipse > Liferay Project > Portlet > JSF 2.x > Primefaces 创建了一个新项目。然后我试图通过demo 向它添加 Spring Bean 管理。

问题是在部署到 tomcat 7 时，生成的 portlet 会引发异常。

源文件：jndi:/localhost/jsf-test-portlet/WEB-INF/faces-config.xml 原因：类 'org.springframework.web.jsf.el.SpringBeanFacesELResolver' 缺少运行时依赖项：java.lang.NoClassDefFoundError: org/springframework/beans/factory/access/el/SpringBeanELResolver

如果我查看项目“lib”目录，jars 就在适当的位置，在生成的 WAR 中也是如此。所以我不知道问题可能出在哪里。

Answer 1

从demo分析WAR，发现里面有7个Spring JARS， 我将剩余的依赖项添加到我的ivy.xml 文件中，然后是“清理/部署”，现在它可以工作了。也许不是所有的 JARS 都是必需的，但这是下一步，删除那些不必要的。

我的ivy.xml 现在看起来像这样：

<?xml version="1.0"?>
<ivy-module
version="2.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
