org.glassfish.jersey.servlet.ServletContainer ClassNotFoundException

java classnotfoundexception tomcat glassfish jersey

我一直在使用ClassNotFoundException，但它在昨晚开始，当我尝试使用Eclipse Juno启动/重新启动我的Tomcat服务器（v7）时，它特别开始了。org.glassfish.jersey.servlet.ServletContainer

不知道发生了什么。奇怪的是，它昨晚才开始发生，而在此之前它的工作非常好。

下面是堆栈跟踪：

问题：

java.lang.ClassNotFoundException: org.glassfish.jersey.servlet.ServletContainer

表示您尝试使用泽西岛 2.x servlet，但您正在提供泽西岛 1.x 库。

对于泽西岛1.x，您必须这样做：

<servlet>
  <servlet-name>Jersey REST Service</servlet-name>
<servlet-class>
  com.sun.jersey.spi.container.servlet.ServletContainer
</servlet-class>
  <init-param>
    <param-name>com.sun.jersey.config.property.packages</param-name>
    <param-value>sample.hello.resources</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>Jersey REST Service</servlet-name>
  <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

有关更多信息，请查看泽西岛 1.x 文档。

如果你想使用泽西岛2.x，那么你必须提供泽西岛2.x库。在基于 maven 的项目中，您可以使用以下内容：

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.xx</version>
</dependency>
<!-- if you are using Jersey client specific features without the server side -->
<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-client</artifactId>
    <version>2.xx</version>
</dependency>

对于 Jersey 2.x，您无需在中设置任何内容，只需提供类似于以下内容的类就足够了：web.xml

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("rest")
public class ApplicationConfig extends Application {

}

有关详细信息，请查看泽西岛文档。

答案 2

这是一个日食设置问题，而不是泽西岛问题。

来自此线程 ClassNotFoundException： org.glassfish.jersey.servlet.ServletContainer

右键单击 eclipse 项目属性 -> 部署程序集 -> 添加 -> Java 构建路径条目 -> Gradle 依赖项 ->完成。

因此，当Apache启动时，Eclipse没有使用Gradle依赖项。
