CDI Weld忽略排除

标签： java maven cdi weld

我正在使用Weld SE在我的应用程序中使用CDI。由于某些库可能有@Inject注释，并且不想让Weld扫描所有库。因此，我想在beans.xml中排除某些包前缀：

<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="com.**" />
        <exclude name="org.**" />
        <exclude name="io.**" />
        <exclude name="groovy.**" />
    </scan>
</beans>

但在执行时我收到以下错误：

我正在使用以下焊接版本：

    <dependency>
        <groupId>org.jboss.weld.se</groupId>
        <artifactId>weld-se</artifactId>
        <version>2.2.1.Final</version>
    </dependency>

如何阻止Weld尝试扫描这些类，这里究竟失败了什么？

我检查了beans.xml的格式至少十次，应该是正确的。我想要 排除所有这些包前缀。该项目是一个maven项目，包含jar中的所有依赖项（org。**应该防止焊接扫描本身）。

答案 0 :(得分：5)

可能是因为没有从旧的部署/编译周期中清除类，例如缺少mvn clean或旧类文件删除：https://vaadin.com/forum#!/thread/10600799/10604748
