[英]Jersey java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer
问题描述
I'm trying to make a web-service with Tomcat and Eclipse using jersey library.
我正在尝试使用 jersey 库使用 Tomcat 和 Eclipse 制作网络服务。 This is my service class:这是我的服务类：
package com.gontuseries.university;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
@Path("/university")
public class UniversityRestWs {
@GET
@Produces(MediaType.TEXT_HTML)
public String getHtmlUniversityInfo(){
return "<html><body>test</body></html>";
}
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getTextUniversityInfo(){
return "test";
}
}
And this is file web.xml这是文件 web.xml
<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>com.gontuseries.university</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>Jersey REST Service</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
When i test my service i get java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer I downloaded jersey from https://jersey.java.net/download.html当我测试我的服务时，我得到 java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer 我从https://jersey.java.net/download.html下载了球衣

For me the problem was that the server had no jars in the lib folder.对我来说，问题是服务器的 lib 文件夹中没有 jar。 Make sure it has access to all dependencies in: project -> properties -> development assembly -> add -> java build path entries.确保它可以访问以下所有依赖项：项目 -> 属性 -> 开发程序集 -> 添加 -> java 构建路径条目。

We need to use provide build path to Eclipse .我们需要使用提供到 Eclipse 的构建路径。 That must resolve issue.那必须解决问题。
Make sure it has access to all dependencies in: project -> properties -> development assembly -> add -> java build path entries --> maven dependency确保它可以访问以下所有依赖项：项目 -> 属性 -> 开发程序集 -> 添加 -> java 构建路径条目 -> maven 依赖项

Are you using Jersey 2.x?您使用的是 Jersey 2.x 吗？ If so, the ServletContainer class has been moved to another package.如果是，则ServletContainer类已移至另一个包。 This article has some good info on how to change your web.xml when migrating from Jersey 1.7 to 2.x: https://java.net/projects/jersey/lists/users/archive/2013-06/message/91 .本文提供了一些关于如何在从 Jersey 1.7 迁移到 2.x 时更改 web.xml 的好信息： https : //java.net/projects/jersey/lists/users/archive/2013-06/message/91 。

com.sun.jersey.spi.container.servlet.ServletContainer类包含在“jersey-servlet.jar”中，因此您应该将它与“jersey-server.jar”一起放到 WEB-INF/lib 中。

I was getting this error in an Eclipse project that had previously worked fine, running on Tomcat 7.0.我在 Eclipse 项目中遇到此错误，该项目以前运行良好，在 Tomcat 7.0 上运行。 Eventually I solved it by removing the project from Tomcat and adding it back again.最终我通过从 Tomcat 中删除项目并重新添加它来解决它。

We get this error because of build path issue and outdated dependency names.Latest one's start from org.glassfish and not com.sun.After replacing with latest dependencies for 2.0, You should add "Server Runtime" libraries in Build Path.我们收到此错误是因为构建路径问题和过时的依赖项名称。最新的从 org.glassfish 而不是 com.sun 开始。替换为 2.0 的最新依赖项后，您应该在构建路径中添加“服务器运行时”库。
"java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer" “java.lang.ClassNotFoundException：com.sun.jersey.spi.container.servlet.ServletContainer”
Please follow below steps to resolve class not found exception.请按照以下步骤解决找不到类的异常。
Right click on project --> Build Path --> Build Path --> Add Library --> Server Runtime --> Apache Tomcat v7.0右键单击项目--> 构建路径--> 构建路径--> 添加库--> 服务器运行时--> Apache Tomcat v7.0
