org.glassfish.jersey.servlet.ServletContainer ClassNotFoundException

我用org.glassfish.jersey.servlet.ServletContainer得到了一个ClassNotFoundExceptionexception，但是当我试图用Eclipse Juno启动/重新启动我的Tomcat服务器（v7）时，它特别地在昨晚开始了。

不知道发生了什么事。 奇怪的是，昨天晚上刚刚开始发生的事情，在此之前，它已经完美地工作了。

这里是堆栈跟踪：

这是我的web.xml

我确信泽西岛的jar文件仍然存在于WEB-INF / lib中：

Answer 1

问题：

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

表示您尝试使用Jersey 2.x servlet，但是您正在提供Jersey 1.x库。

对于Jersey 1.x，你必须这样做：

 <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Jersey 1.x文档 。

如果您不想使用Jersey 2.x，那么您将不得不提供Jersey 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，你不需要在你的web.xml设置任何东西，只需要提供类似下面的类：

 import javax.ws.rs.ApplicationPath; import javax.ws.rs.core.Application; @ApplicationPath("rest") public class ApplicationConfig extends Application { } 

有关更多信息，请查看Jersey文档 。

也可以看看：

• java.lang.ClassNotFoundException：com.sun.jersey.spi.container.servlet.ServletContainer
• Jersey服务与Tomcat和Eclipse
• 启动tomcat时发生ClassNotFoundException

Answer 2

这是一个日食设置问题，而不是泽西岛问题。

从这个线程ClassNotFoundException：org.glassfish.jersey.servlet.ServletContainer

右键单击你的eclipse项目Properties – > Deployment Assembly – > Add – > Java Build Path Entries – > Gradle Dependencies – > Finish。

所以Eclipse在Apache启动时并没有使用Gradle依赖。

Answer 3

如果您使用的是Jersey 2.x，请使用以下依赖项：

 <dependency> <groupId>org.glassfish.jersey.containers</groupId> <artifactId>jersey-container-servlet-core</artifactId> <version>2.XX</version> </dependency> 

XX可以是任何你想要的特定版本。 泽西容器 。

Answer 4

下面的代码在web.xml文件中为我工作

 <servlet> <servlet-name>WebService</servlet-name> <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class> <init-param> <param-name>jersey.config.server.provider.packages</param-name> <param-value>com.example.demo.webservice</param-value> //Package </init-param> <init-param> <param-name>unit:WidgetPU</param-name> <param-value>persistence/widget</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>WebService</servlet-name> <url-pattern>/webservices/*</url-pattern> </servlet-mapping> 

Answer 5

假设您使用Jersey 2.25.1，这对我有用 – 我使用Apache Tomcat Web容器：

  <dependency> <groupId>org.glassfish.jersey.core</groupId> <artifactId>jersey-server</artifactId> <version>2.25.1</version> </dependency> <dependency> <groupId>org.glassfish.jersey.containers</groupId> <artifactId>jersey-container-servlet</artifactId> <version>2.25.1</version> </dependency> 

注意：用您使用的版本replace版本
