Question

我的Jersey 2.13带有Tomcat 7的网络服务。但是当我尝试在服务器上运行时，我有这个错误：

我忘了什么？

我不认为Tomcat 7包含CDI＆＃34;开箱即用＆＃34;，所以如果你想使用它，你需要在你的WAR文件中捆绑一个CDI实现。 JBoss Weld是CDI的参考实现，你使用它可能是最简单的。如果您正在使用Maven，请在dependencies部分中添加以下内容：

<dependency>
  <groupId>org.jboss.weld.servlet</groupId>
  <artifactId>weld-servlet</artifactId>
  <version>1.1.10.Final</version>
</dependency>
<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>3.0.1</version>
  <scope>provided</scope>
</dependency>
