NoClassDefFoundError ProcessingException while migrating from jersey 1.x to jersey 2.x ( 2.8 )
提问by Sadanand
I developed a web service application which was working fine with jersey 1.x ( 1.16 ) I recently tried to migrate to latest stable jersey version 2.8
我开发了一个 Web 服务应用程序，它在 jersey 1.x ( 1.16 ) 上运行良好 我最近尝试迁移到最新的稳定 jersey 版本 2.8
I deleted all jersey jar files of v1.16 then I downloaded jersey jars of v2.8 from the link - https://jersey.java.net/download.html
我删除了 v1.16 的所有球衣 jar 文件，然后我从链接下载了 v2.8 的球衣罐 - https://jersey.java.net/download.html
As per documentation I came to know that, I should have latest servlet jar, servlet jar 2.5 or above, So I downloaded servlet-api-2.5.jar and added the same to /libs folder.
根据我了解到的文档，我应该有最新的 servlet jar、servlet jar 2.5 或更高版本，所以我下载了 servlet-api-2.5.jar 并将其添加到 /libs 文件夹中。
I downloaded javax.ws.rs-api-2.0-m09.jar and added it to /libs I also added latest jettison v 1.3.3 to /libs
我下载了 javax.ws.rs-api-2.0-m09.jar 并将其添加到 /libs 我还将最新的 jettison v 1.3.3 添加到 /libs
But I am getting exception when I run on tomcat7 as follows What are the exact steps to migrate from jersey 1.x to 2.x ? What is missing here ?
但是当我在 tomcat7 上运行时出现异常如下从 jersey 1.x 迁移到 2.x 的确切步骤是什么？这里缺少什么？

If I include configuration class by extending ResourceConfig class I get strange error as follows.
如果我通过扩展 ResourceConfig 类来包含配置类，则会出现如下奇怪的错误。
Multiple markers at this line
- The type javax.ws.rs.core.Configurable cannot be resolved. It is indirectly referenced
from required .class files
- The hierarchy of the type AppConfiguration is inconsistent
Update - Solution to the problem
1> Add all the jar files given jaxrs-ri folder which you download as jersey 2.8 from the link
https://jersey.java.net/download.html
更新 - 问题的解决方案 1> 添加所有给定 jaxrs-ri 文件夹的 jar 文件，您从链接https://jersey.java.net/download.html下载这些文件为 jersey 2.8
Add jar files from all the folders , "lib", "ext", "api"
从所有文件夹中添加 jar 文件，“lib”、“ext”、“api”
2> Add the jar files listed in the below post Can't enable POJO based JSON binding support for Hymanson in Jersey 2.0
2> 添加以下帖子中列出的 jar 文件 Can't enable POJO based JSON binding support for Hymanson in Jersey 2.0
Now jersey 2.8 works perfectly ..
现在球衣 2.8 完美运行..

Exception you are getting is happening because you downloaded "javax.ws.rs-api-2.0-m09.jar"this jar doesn't have ProcessingException download the latest one
你得到的异常正在发生，因为你下载了“javax.ws.rs-api-2.0-m09.jar”这个 jar 没有 ProcessingException 下载最新的
Class not foundCaused by: java.lang.NoClassDefFoundError: javax/ws/rs/ProcessingException
Download this jar javax.ws.rs-api-2.0.jar
下载这个jar javax.ws.rs-api-2.0.jar
<dependency>

Secondly I think you are missing a part from your web.xml
其次，我认为您缺少 web.xml 中的一部分
Try adding these things to your web.xml as appropriate for you application. If you don't have this section this may also lead to SEVERE: A child container failed during start....
尝试将这些内容添加到适合您的应用程序的 web.xml 中。如果您没有此部分，这也可能导致严重：启动期间子容器失败....
This is what you are missing. Please note that param-value is the list of packages that contain your rest services.
这就是你所缺少的。请注意 param-value 是包含您的休息服务的包列表。
<servlet>
<servlet-name>jersey-serlvet</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages;org.codehaus.Hymanson.jaxrs</param-name>
<param-value>com.your.package.for.rest</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
To get latest Hymanson use thisLink
要获得最新的Hyman逊，请使用此链接
<dependency>
<groupId>com.fasterxml.Hymanson.jaxrs</groupId>
<artifactId>Hymanson-jaxrs-json-provider</artifactId>
<version>2.3.3</version>
</dependency>

If you are working in eclipse. Just remove the libraries from Deployment Assembly and add them again. Sometimes after adding new jar does not update the library of the web application
如果您在日食中工作。只需从部署程序集中删除库并再次添加它们。有时添加新jar后不会更新web应用程序的库
BuildPath->Deployment Assembly
BuildPath->部署程序集
