WL 12.2.1 和 12.1.3 上的 Jersey 2.x Web APP [英] Jersey 2.x Web APP on WL 12.2.1 and 12.1.3
本文介绍了WL 12.2.1 和 12.1.3 上的 Jersey 2.x Web APP的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个使用 WebLogic 12.1.3 的 Web 应用程序，它需要一个指向正确 jersey 库的指针.
我基于 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.
这在 12.1.3 中正常运行.
但是，使用此配置文件 WL 12.2.1 会引发错误.

我正在使用
2.23.1 如何在不更改配置文件的情况下使其在两个版本上运行?我希望拥有相同的代码库，并且只需部署到多个版本的 WebLogic，而不必担心库版本.
解决方案
在 weblogic.xml 中的
<!-- apis --><resource-name>javax.ws.rs.*</resource-name><!-- 球衣--><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><资源名称>org.glassfish.hk2.*</resource-name><资源名称>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".
I have a web application working with WebLogic 12.1.3 it needs to have a pointer to the correct jersey libraries.
I created a weblogic.xml file in webapp/WEB-INF folder based on a similar issue here on SW but that only solves part of the problem.
<?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 -->

</prefer-application-packages>
</container-descriptor>
</weblogic-web-app>
This runs properly in 12.1.3.
However with this config file WL 12.2.1 throws an error.
org.glassfish.jersey.internal.ServiceConfigurationError: org.glassfish.jersey.server.spi.ComponentProvider: The class org.glassfish.jersey.ext.cdi1x.internal.CdiComponentProvider implementing the provider interface org.glassfish.jersey.server.spi.ComponentProvider is not found.

Removing that configuration makes it run in 12.2.1.
Im using
<jersey.version>2.23.1</jersey.version>
How can I make it run on both versions without having to change the config file? I want to have the same code base and simply deploy to multiple versions of WebLogic without having to worry about library versions.

Next to <prefer-application-packages> in weblogic.xml add:
<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.jvnet.hk2.*</resource-name>
<resource-name>org.jvnet.hk2.tiger_types.*</resource-name>
</prefer-application-resources>
... and check whether it really is "hk2.tiger_types" or only "tiger_types".
