从球衣 1.x 迁移到球衣 2.x ( 2.8 ) 时出现 NoClassDefFoundError ProcessingException答案

【问题标题】：NoClassDefFoundError ProcessingException while migrating from jersey 1.x to jersey 2.x ( 2.8 )从球衣 1.x 迁移到球衣 2.x ( 2.8 ) 时出现 NoClassDefFoundError ProcessingException
【发布时间】：2014-06-28 14:44:26
【问题描述】：

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球衣版本 2.8

我删除了 v1.16 的所有 jersey jar 文件然后我从链接下载了 v2.8 的球衣罐 - https://jersey.java.net/download.html

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。

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

但是当我在tomcat7上运行时出现异常，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？

我的 Web.xml 如下所示

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

  </servlet>
  <servlet-mapping>

  </servlet-mapping>
</web-app>

例外是-

INFO: Server startup in 1452 ms

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。

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 - 问题的解决方案 1> 添加给定 jaxrs-ri 文件夹的所有 jar 文件，您从链接下载为 jersey 2.8
https://jersey.java.net/download.html

从所有文件夹中添加jar文件，“lib”，“ext”，“api”

2> 添加下面帖子中列出的 jar 文件 Can't enable POJO based JSON binding support for Jackson in Jersey 2.0

现在球衣 2.8 完美运行..

【问题讨论】：

我试过了，现在我得到了不同的异常，例如 Caused by: java.lang.NoClassDefFoundError: org/glassfish/jersey/servlet/internal/ServletContainerProviderFactory 你能告诉我步骤吗？从开始？如果可能，请提供指向相应 jar 文件的链接。我问所有步骤的原因是，我觉得有些事情严重错误，如果我解决了一个问题，我会遇到另一个问题。
您好，我应用了您的修复程序，但后来它给出了一些其他异常。然后我才知道我必须包含 jersey 框架附带的所有 jars。当我们下载它包含三个文件夹 Lib、ext、api 时，我应该从所有这些文件夹中添加 jars。我能够解决所有问题，但是当我运行一个简单的 welCome 服务时，它是一个 GET 方法并返回 JSON 响应为 {"Status":"Welcome"} ，它崩溃并抛出异常 org.glassfish.jersey.message。 internal.MessageBodyProviderNotFoundException: MessageBodyWriter not found for media type=application/json, type=class 有什么想法吗？
查看更新来回答。如果您将杰克逊用于 json 等，则需要添加提供的“org.codehaus.jackson.jaxrs”。如果您使用的是杰克逊以外的其他东西，则可能需要添加适合该 jar 的其他行。我认为这将解决您的问题。
我上次回答的更新对您有帮助吗？
没有 vkg，它没有帮助。相反，我通过引用其他一些 stackoverflow 帖子来修复异常。根据帖子，我必须从下载的 jaxrs-ri 文件夹中复制所有 jar 文件。它包含三个文件夹，“lib”、“ext”和“api”，我必须将这三个文件夹中的所有 jar 文件复制到我的应用程序 lib 文件夹中。然后它解决了所有问题

【解决方案1】：

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

下载这个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>

其次，我认为您的 web.xml 缺少一部分

尝试根据您的应用程序将这些内容添加到您的 web.xml 中。如果您没有此部分，这也可能导致 SEVERE: A child container failed during start....

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.jackson.jaxrs</param-name>
        <param-value>com.your.package.for.rest</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

要获取最新的 Jackson，请使用此 Link

<dependency>
    <groupId>com.fasterxml.jackson.jaxrs</groupId>
    <artifactId>jackson-jaxrs-json-provider</artifactId>
    <version>2.3.3</version>
</dependency>

【讨论】：

【解决方案2】：

如果您在 Eclipse 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->部署组装
