从球衣1.x迁移到球衣2.x(2.8)时发生NoClassDefFoundError ProcessingException [英] NoClassDefFoundError ProcessingException while migrating from jersey 1.x to jersey 2.x ( 2.8 )
问题描述
我开发了一个与jersey 1.x(1.16)一起正常工作的Web服务应用程序 我最近尝试迁移到最新的稳定版2.8版
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
我删除了v1.16的所有jersey jar文件 然后我从链接- https://jersey.java.net/download下载了v2.8的球衣罐.html
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
根据文档，我知道我应该拥有最新的servlet jar，servlet jar 2.5或更高版本，因此我下载了servlet-api-2.5.jar并将其添加到/libs文件夹中.
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.
我下载了javax.ws.rs-api-2.0-m09.jar并将其添加到/libs 我还向/libs添加了最新的jettison v 1.3.3
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
但是当我在tomcat7上运行时，我得到了异常，如下所示 从jersey 1.x迁移到2.x的确切步骤是什么?这里缺少什么?
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 ?
我的Web.xml如下
My Web.xml looks as follows

如果我通过扩展ResourceConfig类来包含配置类 我收到如下奇怪的错误.
If I include configuration class by extending ResourceConfig class I get strange error as follows.
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
更新-解决问题的方法
1>添加给定的jaxrs-ri文件夹中的所有jar文件，您可以从链接中将其下载为jersey 2.8
https://jersey.java.net/download.html
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
从所有文件夹"lib"，"ext"，"api"中添加jar文件
Add jar files from all the folders , "lib", "ext", "api"
2>添加以下帖子中列出的jar文件 无法启用基于POJO的功能在Jersey 2.0中对Jackson的JSON绑定支持
2> Add the jar files listed in the below post Can't enable POJO based JSON binding support for Jackson in Jersey 2.0
现在，球衣2.8可以完美使用..
Now jersey 2.8 works perfectly ..
推荐答案
由于下载了"javax.ws.rs-api-2.0-m09.jar" 这个罐而导致发生异常没有ProcessingException下载最新的
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
Class not foundCaused by: java.lang.NoClassDefFoundError: javax/ws/rs/ProcessingException
下载此jar javax.ws.rs-api-2.0.jar
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>javax.ws.rs-api</artifactId>
<version>2.0</version>
</dependency>
第二，我认为您缺少web.xml中的一部分
Secondly I think you are missing a part from your web.xml
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，则可能还会导致严重:子容器在启动过程中失败....
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....
这就是您所缺少的.请注意，param-value是包含您的休息服务的软件包的列表.
