Spring boot IllegalStateException:未能内省类

我试图在我的SpringBoot应用程序上实现扩展功能，@ComponentScan应该在类路径中的一个单独的jar中扫描bean定义

@ComponentScan如下所示

@ComponentScan({"com.myapp.rest","com.mycompany.search.rest"})

其中包“com.mycompany.search.rest”将出现在外部jar ESExt.jar中

我在WebSphereLiberty服务器的

server.xml

文件中添加了以下配置，以包括用于类路径扫描的外部文件夹

<library id="extention" apiTypeVisibility="+third-party, -api">
  <fileset dir="${server.config.dir}/ext" includes="*.jar" scanInterval="5s" />
</library>

<webApplication id="Myapp" location="Myapp.war" type="war" name="Myapp" contextRoot="/resources">
    <classloader commonLibraryRef="extention" />
</webApplication>

下面是jar-tf ESExt.jar的输出

META-INF/
META-INF/MANIFEST.MF
com/
com/mycompany/
com/mycompany/search/
com/mycompany/search/rest/
com/mycompany/search/rest/StoreResource.class

---

此异常

IllegalStateException:Failed to introspect Class

甚至是什么意思？我甚至在互联网上找不到任何关于它的信息。

通过如下更改

server.xml解决了这个问题

<library id="extension">
    <fileset dir="${server.config.dir}/ext" includes="*.jar" scanInterval="5s" />
</library>
    
<webApplication id="Myapp" location="Myapp.war" type="war" name="Myapp" contextRoot="/resources">
    <classloader commonLibraryRef="extension" delegation="parentFirst"/>
</webApplication>



<library id="extension">
    <fileset dir="${server.config.dir}/ext" includes="*.jar" scanInterval="5s" />
</library>
    
<webApplication id="Myapp" location="Myapp.war" type="war" name="Myapp" contextRoot="/resources">
    <classloader commonLibraryRef="extension" delegation="parentFirst"/>
</webApplication>
