I have been unable to inject a service from the spring context using the @Context annotation.我一直无法使用 @Context 注释从 spring 上下文注入服务。 I cannot see what I am missing.我看不到我错过了什么。
I have uploaded my project: here我已经上传了我的项目： 这里
I have this line of configuration in conf/neo4j-server.properties我在 conf/neo4j-server.properties 中有这行配置
org.neo4j.server.thirdparty_jaxrs_classes=test.testload=/loader

What am I missing that will allow me to access the spring context?我缺少什么可以让我访问 spring 上下文？ Why is the Plugin Lifecycle class called out in: META-INF/services/org.neo4j.server.plugins.PluginLifecycle being ignored?为什么在 META-INF/services/org.neo4j.server.plugins.PluginLifecycle 中调用 Plugin Lifecycle 类被忽略？

AFAIK the implementations if PluginLifecycle are not detected via serviceloader, so get rid of META-INF/services/org.neo4j.server.plugins.PluginLifecycle .如果没有通过 serviceloader 检测到PluginLifecycle则AFAIK 实现，因此摆脱META-INF/services/org.neo4j.server.plugins.PluginLifecycle 。
Instead move your PluginLivecycle implementation ( ImportConfig ) to a package being exposed in config org.neo4j.server.thirdparty_jaxrs_classes - in your case test.testload instead of test.testload.config .而是将您的PluginLivecycle实现（ ImportConfig ）移动到配置org.neo4j.server.thirdparty_jaxrs_classes中公开的包 - 在您的情况下test.testload而不是test.testload.config 。
