我使用“jersey”原型在eclipse中开发了一个非常小的restful Web服务。我也成功地在tomcat中部署了它。但是，我无法在 weblogic 12c 中部署它。这是我到目前为止所尝试的：

  1. 正如我在其中一篇文章中看到的那样，创建了一个包含球衣库的共享库。这是我的 pom.xml，它生成包含所需清单文件的共享库：

  1. 将 weblogic 服务器中的战争部署为“库”

  2. 在我的 webservice 应用程序的 WEB-INF 文件夹下添加了一个 weblogic.xml，其中包含以下条目：http://xmlns.oracle.com/weblogic/weblogic-web-app/1.7/weblogic-web-app.xsd">

        <wls:library-ref>
        <wls:library-name>jax-rs</wls:library-name>
        <wls:specification-version>2.0</wls:specification-version>
        <wls:implementation-version>2.21</wls:implementation-version>
         <exact-match>false</exact-match>
    </wls:library-ref>
  3. 使用下面的 pom.xml 生成了 web-service war 文件

      <jersey.version>2.21</jersey.version>
      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>
</project>

并使用以下 we.xml 条目：

<?xml version="1.0" encoding="UTF-8"?>
<!-- This web.xml file is not required when using Servlet 3.0 container,
     see implementation details http://jersey.java.net/nonav/documentation/latest/jax-rs.html -->

            <param-name>jersey.config.server.provider.packages</param-name>
            <param-value>com.cts.WLRest</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Jersey Web Application</servlet-name>
        <url-pattern>/webapi/*</url-pattern>
    </servlet-mapping>
</web-app>

现在，当我尝试在 weblogic 中部署战争时，它会引发以下异常：

我还使用了 maven 依赖树和 Jshades 来确认不同版本的 jar 之间没有冲突。对此的任何帮助或指示将不胜感激。

这是因为 Weblogic 为某些库放置了自己的 jar。在这种情况下，它是旧版本的 jax-rs。您可以看到此方法是 JAX-RS 2 的新方法：

应用程序 javadoc

为了强制执行您的包，您需要在 WLS 中配置首选应用程序包：

首选应用程序包

您还需要了解这一点：

WLS 中的类加载
