Question

我正在使用Java AngularJS和Mysql创建Web应用程序，但是当我使用apache服务器运行它时，我收到此错误：

GRAVE: Servlet [jersey-serlvet] in web application [/helloWorld] threw load() exception java.lang.ClassNotFoundException: 
com.sun.jersey.spi.container.servlet.ServletContainer

这是我的pom.xml：

我不认为，您需要包含以下内容，因为您已经包含jersey-server。请删除它们并重新部署应用程序。

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-servlet</artifactId>
    <version>1.17.1</version>
</dependency>
<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-json</artifactId>
    <version>1.17.1</version>
</dependency>

另外，请注意， 您需要在运行时包含相同的库，因为您在运行时会收到此异常。
