无法在 weblogic 服务器上部署 jersey REST，是否有特定于 weblogic 的 REST 服务配置？

已解决！

问题不在于 weblogic 服务器，问题是我的源代码在单独的文件夹而不是 src 中，因此 weblogic 无法在 src 文件夹中找到要扫描的包，因此在 pom.xml，部署成功 -

<plugin>
   <artifactId>maven-resources-plugin</artifactId>
   <version>3.0.2</version>
   <executions>
      <execution>
         <id>copy-source</id>
         <phase>generate-sources</phase>
         <goals>
            <goal>copy-resources</goal>
         </goals>
         <configuration>
            <outputDirectory>co/src</outputDirectory>
            <overwrite>true</overwrite>
            <resources>
               <resource>
                  <directory>${basedir}/co/EBP</directory>
               </resource>
            </resources>
         </configuration>
      </execution>
   </executions>
</plugin>

通过使用此插件，我将我的独立文件夹源代码复制到 src 文件夹，并将覆盖设置为 true。因此在 src 文件夹中提供了源代码。

这个问题也可以通过在 .classpath 文件中提及源文件夹来解决。
