java - WL 12.2.1 和 12.1.3 上的 Jersey 2.x Web 应用程序

Question

我有一个使用 WebLogic 12.1.3 的 Web 应用程序，它需要有一个指向正确 Jersey 库的指针。

我根据 SW 上的类似问题在 webapp/WEB-INF 文件夹中创建了一个 weblogic.xml 文件，但这只能解决部分问题。

<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app
        xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.4/weblogic-web-app.xsd">

    <container-descriptor>
        <prefer-application-packages>
            <!-- apis -->
            <package-name>javax.ws.rs.*</package-name>

            <!-- jersey providers -->
            <package-name>com.sun.jersey.*</package-name>
            <package-name>org.glassfish.jersey.*</package-name>

            <package-name>jersey.repackaged.*</package-name>

            <!-- hk2 -->
            <package-name>org.jvnet.hk2.*</package-name>
            <package-name>org.jvnet.hk2.tiger_types.*</package-name>
            <package-name>org.glassfish.hk2.*</package-name>

        </prefer-application-packages>
    </container-descriptor>
</weblogic-web-app>

这在 12.1.3 中可以正常运行。

但是，使用此配置文件 WL 12.2.1 会引发错误。

删除该配置可使其在 12.2.1 中运行。

我正在使用

<jersey.version>2.23.1</jersey.version>

如何使其在两个版本上运行而无需更改配置文件？我希望拥有相同的代码库并简单地部署到多个版本的 WebLogic，而不必担心库版本。

Answer 1

在 <prefer-application-packages> 旁边在 weblogic.xml 添加:

<prefer-application-resources>
  <!-- apis -->
  <resource-name>javax.ws.rs.*</resource-name>
  <!-- jersey -->
  <resource-name>META-INF/services/org.glassfish.jersey.*</resource-name>
  <resource-name>com.sun.jersey.*</resource-name>
  <resource-name>org.glassfish.jersey.*</resource-name>
  <resource-name>jersey.repackaged.*</resource-name>
  <!-- hk2 -->
  <resource-name>META-INF/services/org.glassfish.hk2.*</resource-name>
  <resource-name>org.glassfish.hk2.*</resource-name>
  <resource-name>org.jvnet.hk2.*</resource-name>
  <resource-name>org.jvnet.hk2.tiger_types.*</resource-name>
</prefer-application-resources>

...并检查它是否真的是“hk2.tiger_types ”或只是“tiger_types ”。
