一下错误是因为在MyEclipse中导入xfire会自动导入spring1.2.6，然后自己又导入spring2.0引起的版本冲突(仅在使用ClassPathXmlApplicationContext,FileSystemXmlApplicationContext的情况下)，导致程序无法做单元测试。

ConfigurableWebApplicationContext ctx = new XmlWebApplicationContext(); ctx.setConfigLocations(new String[] { "classpath:applicationContext.xml" }); ctx.refresh();
