java - 尝试在 Tomcat 7 中使用 Jersey (JAX-RS) 和 Weld (CDI)。为 javax.annotation.ManagedBean 获取 noClassDefFoundError

Question

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。实际的异常(exception)是

java.lang.NoClassDefFoundError: javax/annotation/ManagedBean

但我没有使用 @ManagedBean 批注明确地批注任何内容，所以我猜测 Weld 隐式地执行了此操作。这个注解应该由 Weld 提供，还是我遗漏了其他一些依赖项？

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？

servlet 以 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，日志文件显示了应用程序正在重新部署的样子!

我遇到了完全相同的问题，我通过删除当前版本的 Jersey 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。
