从jersey 1.x迁移到jersey 2.x时的NoClassDefFoundError ProcessingException（2.8）

时间：2014-05-11 03:46:23

标签： java tomcat jersey jersey-2.0

我开发了一个网络服务应用程序，它与jersey 1.x（1.16）一起运行良好 我最近尝试迁移到最新的稳定版球衣2.8版

我删除了v1.16的所有jersey jar文件 然后我从链接 - https://jersey.java.net/download.html

下载了v2.8的球衣罐子

根据文档我知道，我应该有最新的servlet jar，servlet jar 2.5或者以上，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 我还添加了最新的jettison v 1.3.3到/ libs

但是我在tomcat7上运行时遇到异常，如下所示 从jersey 1.x迁移到2.x的具体步骤是什么？这里缺少什么？

我的Web.xml如下所示

  </servlet>
  <servlet-mapping>
    <servlet-name>Temp REST Service</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>
</web-app>

例外是 -

如果我通过扩展ResourceConfig类来包含配置类 我得到如下奇怪的错误。

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 - 解决问题的方法 1 GT;给出jaxrs-ri文件夹下的所有jar文件，你可以从链接中下载为jersey 2.8 https://jersey.java.net/download.html

从所有文件夹中添加jar文件，＆＃34; lib＆＃34;，＆＃34; ext＆＃34;，＆＃34; api＆＃34;

2 - ;添加以下帖子中列出的jar文件 Can't enable POJO based JSON binding support for Jackson in Jersey 2.0

现在球衣2.8完美运作..

答案 0 :(得分：10)

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>

其次我认为你错过了web.xml中的一部分

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，这也可能导致严重：子容器在启动期间失败....

这就是你所缺少的。请注意，param-value是包含其余服务的软件包列表。 

<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>

要获得最新杰克逊使用此 Link 

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

答案 1 :(得分：1)

如果你在eclipse工作。只需从Deployment Assembly中删除库并再次添加它们。有时在添加新jar后不会更新Web应用程序库

BuildPath - ＆gt; 部署程序集
