Java 由于通过构造函数参数0表示的依赖关系未得到满足，因此未进行此定义

我使用库X的类标记为@Provider（JAX-RS的注释）

我想扩展X的功能，因此我扩展了类：

@Provider
public class WrappedX extends ContainerRequestFilter,
ContainerResponseFilter {
     private final X objectX;
     public WrappedX (X objectX) { this.objectX = objectX; } }
     @Override
     <Some function1>
     @Override
     <Some function2>
}

当我运行此命令时，会出现以下错误：

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: 
    Error creating bean with name 'getWrappedXFilter' defined in file 
    [<path>/WrappedX.class]: 

 Unsatisfied dependency expressed through constructor argument with index 0 of type  [org.company.package1.X]: : No qualifying bean of 
 type [org.company.package1.X] found for dependency: 
     expected at least 1 bean which qualifies 
     as autowire candidate for this dependency. 
  Dependency annotations: {};  nested exception is 
 org.springframework.beans.factory.NoSuchBeanDefinitionException: 
    No qualifying bean of type [org.company.package1.X] found 
    for dependency: expected at least 1 bean 
    which qualifies as autowire candidate for this dependency. 
  Dependency annotations: {}

原因：org.springframework.beans.factory.unsatifiedDependencyException:
创建文件中定义了名为“getWrappedXFilter”的bean时出错
[/WrappedX.class]：
通过具有[org.company.package1.X]类型的索引0的构造函数参数表示的未满足的依赖关系：没有

依赖项注释：{}；嵌套异常是

我看到另一段代码与我所做的完全相同。但他们的代码运行得很好。有人能解释一下这里发生了什么吗？

你能发布完整的堆栈跟踪吗？你能发布关于类路径扫描的配置吗？我最好的猜测是您尝试注入的bean没有被spring拾取。@ComponentScan（basePackages=“org.company.package1”）这个类org.company.package1.X是如何生成bean的？你能分享X类吗？它不是豆做的。类X只是一个javax-rs@Provider类。
