Spring 引导 JAX-RS/CXF 依赖项注入在 JAR 中有效，但在 WAR 中无效
Spring Boot JAX-RS/CXF dependency injection works in JAR but not WAR
我正在用 Spring 使用 cxf.jaxrs.classes-scan and cxf.jaxrs.classes-scan-packages 的引导应用程序包装现有的普通 JAX-RS 应用程序 JAR。当我 运行 作为 JAR 或 maven spring-boot:run 时，依赖注入工作正常。当我 运行 作为 WAR（在 WebSphere Liberty 17.0.0.2 上）时，@Inject-able 字段在 REST 请求期间是 null。
这是 SpringBootApplication:
@SpringBootApplication(scanBasePackages = { "com.test" })
public class CustomerServiceApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(CustomerServiceApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(CustomerServiceApplication.class);
}
}
这里是src/main/resources/application.properties：
cxf.path=/
cxf.jaxrs.classes-scan=true
cxf.jaxrs.classes-scan-packages=com.test,com.fasterxml.jackson.jaxrs.json
这是 Maven pom.xml（原始 JAX-RS 应用程序 JAR 是 customerservice-java，它位于本地存储库中）：

如果我在 application.properties 中启用 logging.level.org.springframework.beans.factory.support=TRACE，我会看到依赖注入在应用程序启动期间起作用：
DEBUG o.s.b.f.s.DefaultListableBeanFactory - Creating shared instance of singleton bean 'customerService'
DEBUG o.s.b.f.s.DefaultListableBeanFactory - Creating instance of bean 'customerService'
DEBUG o.s.b.f.s.DefaultListableBeanFactory - Eagerly caching bean 'customerService' to allow for resolving potential circular references

DEBUG o.s.b.f.s.DefaultListableBeanFactory - Returning cached instance of singleton bean 'customerService'
DEBUG o.s.b.f.s.DefaultListableBeanFactory - Finished creating instance of bean 'com.test.CustomerServiceRest'
但是，当我发出 REST 请求时，我可以看到每个请求都会创建一个 CustomerServiceRest 的新实例（System.out.println 在构造函数中）并且 @Inject-able依赖项是 null（结果是 NullPointerException）。所以我想也许将 @Singleton 添加到 CustomerServiceRest 会起作用，但是每个请求仍然会创建一个新对象。
有谁知道如何使用单个 Web 服务 bean 或确保 Spring 注入所有依赖项？ vanilla JAX-RS 应用程序 JAR 本身不能承担任何 Spring 依赖项。
此类问题发生在 spring 项目之一
但是，我们在 Class 声明中使用了 @Qualifier("name") 并且在使用 @Inject
自动连接时使用了相同的限定符
我在 Tomcat 8.5.x 和 JDK 1.8 上部署了您的代码，并且成功注入了 CustomerService。
你有机会在 Tomcat 下测试你的 war 吗？至少要了解这是关于代码还是应用服务器的问题。有时 WebSphere/Weblogic 中的嵌入式库会覆盖来自您的 war 包的 jar，并且会出现类似的问题。
我能够通过不使用 Liberty 的 CXF 来解决这个问题（例如，使用 servlet 和 jsp 特性而不是 webProfile 特性 [它引入了 Liberty 的 jaxrs feature]），并在 @SpringBootApplication 注释中添加 exclude = { DispatcherServletAutoConfiguration.class }。这仅适用于我的用例类型（例如微服务），其中 DispatcherServlet 作为默认 servlet 安装在 / 上，而 CXFServlet 使用 cxf.path=/ 安装（因此创建 /* URL 映射）。对于 Spring MVC 与 CXF 混合但 CXF 服务处于非根 URL 映射的其他情况，exclude 不是必需的。我仍在研究如何让它与 Liberty 的 CXF 一起工作，如果我发现了，我会更新这个答案。
我正在用 Spring 使用 cxf.jaxrs.classes-scan and cxf.jaxrs.classes-scan-packages 的引导应用程序包装现有的普通 JAX-RS 应用程序 JAR。当我 运行 作为 JAR 或 maven spring-boot:run 时，依赖注入工作正常。当我 运行 作为 WAR（在 WebSphere Liberty 17.0.0.2 上）时，@Inject-able 字段在 REST 请求期间是 null。

}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(CustomerServiceApplication.class);
}
}
