我遇到了一个我无法找到的问题，我使用了spring web和jsf，我创建了一个jsf托管bean并从xhtml登录页面调用但是我无法访问托管bean的方法，通常＃{managedBean.METHODNAME} autocompolete工作，但是我的xhtml文件不能正常工作！
我是java新手，对不起我现在的愚蠢错误

谢谢你的帮助......
你需要在你的托管bean中注入你的bean Kullanicilar，以便访问kullaniciad和sifre
注射的例子：
@ManagedProperty("#{kullanicilar }")
private Kullanicilar kullanici; // +setter
您还需要通过添加此批注将Kullanicilar设置为托管bean：
@ManagedBean(name="kullanicilar ")
