Spring boot 弹簧启动执行器中的自定义端点

我正在尝试为Spring Boot应用程序编写自定义端点。我已经编写了自定义端点实现，如下所示。我没有包括额外的东西，如导入，以减少代码的大小

@Component
public class TestendPoint implements Endpoint<List<String>>{

    public String getId() {
        return "test";      
    }

    public List<String> invoke() {
        List<String> test= new ArrayList<String>();
        test.add("Details 1");
        test.add("Details 2");
        return serverDetails;
    }

    public boolean isEnabled() {        
        return true;
    }

    public boolean isSensitive() {      
        return false;
    }

}

除此之外，我有一切运行弹簧启动驱动器。我可以访问默认端点，如/info、/metrics等

如果我遗漏了什么，你能分享一下你的知识吗。我假设自定义端点类将在没有开发人员进一步配置的情况下加载

我已经解决了这个问题。首先，我没有在应用程序类中包含@ComponentScan注释。或者我应该有@SpringBoot应用程序。添加注释时，我开始出现以下异常：

这是由于包装问题。我已尝试从根包执行main类。我不确定这是否是spring boot应用程序中的一个bug，我会在他们的站点上记录一个JIRA。一旦我添加了一个更高级别的包结构，它就开始正常工作。

我应该在spring boot应用程序类中包括@ComponentScan吗。如果我加上，我会得到例外不，这不是一个错误。当你把你的spring boot应用程序放在根包中时，你有一个fat警告日志，它应该让你知道一些东西可能会坏掉。请参阅，谢谢您的澄清。但我没有使用默认包来获取该异常。我使用根包进行组件扫描您的问题看起来正是我创建的新问题#3850
