Question

我有一个包，包中的A类使用@Configuration和ConditionalOnBean(B.class)进行注释，并由spring.factories加载;

在其他软件包的spring bean xml中，有一个工厂Bean C，它自动装配一个bean B;

当我启动服务器时，我找到了bean B和C，但是没有注册bean A.

调试日志显示bean A为负匹配，但spring找到Bean B，日志就像：

[DEBUG] 20180615 17:19:23.200 [localhost-startStop-1] ConfigurationClassBeanDefinitionReader - Registered bean definition for imported class 'A'

[DEBUG] 20180615 17:20:13.609 [localhost-startStop-1] DefaultListableBeanFactory - Finished creating instance of bean 'A'
report
A:
      Did not match:
         - @ConditionalOnBean (types: B; SearchStrategy: all) did not find any beans (OnBeanCondition)
      Matched:
         - @ConditionalOnBean (types: B; SearchStrategy: all) found bean 'defaultB' (OnBeanCondition)

我想知道：

命令springboot注册bean;
为什么报告显示＆＃34;没有找到任何豆子＆＃34;和＃34;找到豆子＆＃34;同时？
