在AnyNestedCondition父类将评估@Conditional的方法说明和使用OR运算符将它们结合起来。 我们可以像任何其他条件一样使用这个条件: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 @Bean @Conditional(OnWindowsOrUnixCondition.class) WindowsOrUnixBean windowsOrUnixBean() { return new WindowsOrUnixBean(); } ...

提交完代码后,存在自定义鉴权拦截器的模块运行正常,然而期望使用默认鉴权拦截器的模块无法正常运行,具体表现为IOC容器未创建DefaultAuthInterceptor实例。因为代码中均是通过注解实现Bean的定义,因此重点关注ConfigurationClassPostProcessor的解析流程。 ConfigurationClassPostProcessor是一个BeanFactory的后置处理器,因此它的主要功...
思考: 为什么不像创建ConfigurationClassPostProcessor对象bean一样使用getBean? Condition是和配置项相关的 , 每个Condition 可能都不一样 , 不可复用, 也就没必要使用bean的方式创建对象从而放入容器中 1/@ConditionalOnJava 1.1/测试程序 1.2/注解定义

Conditional statements are used to control the flow of execution of the Java compiler based on certain conditions. This implies that we are making a choice based on a certain value or the state of a program. The conditional statements that are available in Java are as follows:The if ...
