Jakarta ee 带有CDI和现有JAX-RS服务的Vaadin 12 PWA
我试图将一个vaadin12pwa前端添加到现有的JAX-rsrestful服务中，并使用@Inject将其注入到Vaadin类中，但我一直得到Nullpointer异常 现有服务有一个Jakarta ee 带有CDI和现有JAX-RS服务的Vaadin 12 PWA,jakarta-ee,jax-rs,wildfly,vaadin,thorntail,Jakarta Ee,Jax Rs,Wildfly,Vaadin,Thorntail,我试图将一个vaadin12pwa前端添加到现有的JAX-rsrestful服务中，并使用@Inject将其注入到Vaadin类中，但我一直得到Nullpointer异常 现有服务有一个/json/keystore端点（参见下面的类），而vaadinui有一个as入口点/。结合Vaadin，我无法再访问以前位于/json/keystore的服务 我正在使用最新的Vaadin CDI插件（10.0.2）和Thorntail 2.3.0及其CDI插件，该插件适用于预先存在的类，但在使用Vaadin时
