我试图让 Weld 在 Tomcat 7.0.34 上与 Jersey 一起工作，但似乎遇到了这个问题。实际的例外是

java.lang.NoClassDefFoundError: javax/annotation/ManagedBean

但是我没有用@ManagedBean 注释明确地注释任何东西，所以我猜Weld 隐含地这样做了。Weld 是否应该提供此注释，或者我是否缺少其他一些依赖项？

我的 pom.xml 文件包含：

<dependency>
    <!-- CDI implementation -->
    <groupId>org.jboss.weld.servlet</groupId>
    <artifactId>weld-servlet</artifactId>
    <version>${weld.version}</version>
</dependency>

我是否遗漏了什么，或者尝试使用 Weld 和 Jersey 是否存在更大的问题？

catalina.out 部署我的网络应用程序时：

servlet 使用 500 HTTP 状态代码响应请求。根本原因堆栈跟踪：

奇怪的是，堆栈跟踪没有显示在 catalina.out 中，相反，日志文件显示了正在重新部署的应用程序的样子！

我遇到了同样的问题，一旦我按照以下说明覆盖了 ServletContainer： Weld + Jersey + Tomcat？

为了能够让它运行，我用 @RequestScoped 注释了我的球衣服务类，然后注入工作了。

我遇到了完全相同的问题，我通过删除当前版本的球衣 1.16 并使用旧版本 1.8 解决了这个问题。使用旧版本后，我不再有此错误。

只需查看球衣罐（我使用球衣 1.14），特别是 pom 文件。您会看到它需要一些提供的依赖项，其中之一是 javax.ejb 3.1：

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.ejb</artifactId>
    <version>3.1</version>
    <scope>provided</scope>
</dependency>

这个 jar 包含必要的类：javax.annotation.ManagedBean。如果您导入包含此类的任何其他 jar 将不起作用。那是因为球衣罐的捆绑方式，但那是另一回事了。

只需在您的 pom 中添加此依赖项，一切都会正常。
