SEAM身份验证器可以驻留在ear文件lib文件夹中吗？

对于几个reaons，我们有一个位于我们耳朵的lib目录中的project-commons.jar。

project.ear
  project-web.war
  project-ejb.jar
  lib
    project-commons.jar

目前，如果我将一个放在project-commons.jar中的类注释为

@Name("authenticator")
@Scope(ScopeType.APPLICATION)

SEAM报告堆栈跟踪（下面）。如果我将验证器放在project-web.war或project-ejb.jar中，SEAM就可以找到并使用验证器。要清楚项目公共是从类路径的角度“找到”（project-web和project-ejb.jar中的很多代码都利用它。这个问题似乎特定于components.xml如何解析条目：

<security:identity 
   authenticate-method="#{authenticator.authenticate}" 
   remember-me="true"/>

这是堆栈跟踪：

答案 0 :(得分：4)

尝试在project-commons.jar中添加一个空的seam.properties文件。这用作标记文件，告诉Seam存档中有组件。

问题在于Seam需要“发现”使用@Name注释的组件等。但是，扫描整个类路径可能非常昂贵。这就是为什么Seam只扫描具有seam.properties（或components.xml）文件的档案。

答案 1 :(得分：0)

有 Seam称之为@Authenticator 您必须创建自己的身份验证器组件。

您的错误消息是说Seam找不到任何此类组件，因此这意味着您没有@Name("authenticator")的组件

以下是如何创建身份验证器的示例link

在发现组件时似乎我错了。
