@ComponentScan( excludeFilters = {@Filter( type = FilterType.CUSTOM, classes = {TypeExcludeFilter.class} ), @Filter( type = FilterType.CUSTOM, classes = {AutoConfigurationExcludeFilter.class} )} )是什么意思

这段[代码](https://geek.csdn.net/educolumn/1572ef9b473b4e00f6b2bf6d428b7c27?spm=1055.2569.3001.10083)是用来配置 Spring 的扫描注解，用于扫描包路径中的组件，从而将其注入到 Spring 容器中。其中，excludeFilters = {@Filter( type = FilterType.CUSTOM, classes = {TypeExcludeFilter.class} ), @Filter( type = FilterType.CUSTOM, classes = {[auto](https://geek.csdn.net/educolumn/0ed23d107a440608894f63cac98e73fb?spm=1055.2569.3001.10083)Configur[ati](https://geek.csdn.net/educolumn/150d7073277950db5f09620704e791cf?spm=1055.2569.3001.10083)onExcludeFilter.class} )} 指定了需要排除的组件类型和类名，TypeExcludeFilter.class 排除标记为 @Component 的类，而 [auto](https://geek.csdn.net/educolumn/0ed23d107a440608894f63cac98e73fb?spm=1055.2569.3001.10083)Configur[ati](https://geek.csdn.net/educolumn/150d7073277950db5f09620704e791cf?spm=1055.2569.3001.10083)onExcludeFilter.class 排除自动配置类。

@ComponentScan(excludeFilters = { @Filter(type = FilterType.CUSTOM, classes = TypeExcludeFilter.class), @Filter(type = FilterType.CUSTOM, classes = AutoConfigurationExcludeFilter.class) })

这是一个带有excludeFilters属性的@ComponentScan注解，其中excludeFilters指定了需要排除掉的Bean对象。具体来说，该注解中有两个Filter类型的规则需要排除： 1. type = FilterType.CUSTOM, classes = TypeExcludeFilter.class，表示排除所有Class对象，这些Class对象是Spring框架内部使用的，不需要扫描到。 2. type = FilterType.CUSTOM, classes = AutoConfigurationExcludeFilter.class，表示排除所有自动配置类，这些自动配置类是Spring Boot自动配置功能的一部分，不需要手动进行配置。
