Question

我使用weld se 2.0和其他简单的依赖项构建了一个应用程序。在我的开发环境（eclipse）中，这种方法很好，没有错误，但是......在生产中，应用程序完全崩溃，焊接的实习依赖部分引发了“不明确的依赖关系”错误：

可能是什么原因？我的应用程序在eclipse中正常工作，我的依赖项配置错误或构建过程错误？我能做些什么来避免这种例外？

亲切的问候撒母耳。

Answer 1

嗯，这是一个我必须承认的注意问题，解决方案是将它放在beans.xml文件中：

<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
   version="1.1" bean-discovery-mode="all">
    <scan>
        <exclude name="org.jboss.weld.**" />
    </scan>
</beans>

如下：http://weld.cdi-spec.org/documentation，

抱歉。

Weld仅在生产中具有模糊的依赖性错误
