Wildfly 15和Jersey - 尝试将多个服务定位器注册到单个服务定位器应用程序中

问题描述 投票：3回答：1

我们正在调查将目前正在使用Weblogic的应用程序移至Wildfly 15.0.1.Final。

我们的项目是一个包含多个战争的耳朵，其中两个正在利用泽西（2.27）进行宁静的网络服务。这些是“api”战争和“网络”战争，其端点分别可在“host_name / application / api /”和“host_name / application / web /”访问。

我们正在使用'earlib'gradle语句将我们的球衣库添加到耳中的lib文件夹中，而我们的战争使用'providedCompile'。为了让我们继续使用此设置，我们从standalone.xml中删除了jax-rs。

如果我从部署中删除其中一个战争，它会部署正常，并且Web服务按预期工作。但是，如果我尝试部署两者，我们会收到一个错误，告诉我们它是Trying to register multiple service locators into single service locator application。完整的堆栈跟踪包含在下面，我已经包含了两个有问题的战争的web.xml文件。

有关如何解决此问题的任何建议？我很乐意提供任何其他可能有用的代码片段或信息。

干杯

默认情况下，泽西岛使用的是*Single*InjectionManagerStore：

/**
 * Default {@link InjectionManagerStore injection manager} that assumes only one
 * {@link InjectionManager injection manager} per application is used.
 */

您可以通过在META-INF / services下创建一个平面文件“org.glassfish.jersey.ext.cdi1x.internal.spi.InjectionManagerStore”来切换到备用impl。此文件必须包含一行，其中包含选择的impl的类名。你也许可以尝试使用'ServletInjectionManagerStore'。

查看完整示例here。

另请注意：“在单个WAR / JVM中启用多个Jersey应用程序”:-)

祝好运
