spring 排除指定的类或者包扫描

Posted 2021-02-06 大熊歪歪

<!-- 排除Controller注解的扫描 -->
<context:component-scan base-package="exampleBean">
    <context:exclude-filter type="annotation"
        expression="org.springframework.stereotype.Controller" />
</context:component-scan>


<!-- 排除扫描符合正则表达式的类,此处排除com.wx.comm.util包下的所有类 -->
<context:component-scan base-package="exampleBean">
    <context:exclude-filter type="regex"
        expression="com.wx.comm.util.*" />
</context:component-scan>


<!-- 排除指定包exampleBean下的CommFF类的扫描 -->
<context:component-scan base-package="exampleBean">
    <context:exclude-filter type="assignable"
        expression="exampleBean.CommFF" />
</context:component-scan>

7.10.4 Using filters to customize scanning

By default, classes annotated with @Component, @Repository, @Service, @Controller, or a custom annotation that itself is annotated with @Component are the only detected candidate components. However, you can modify and extend this behavior simply by applying custom filters. Add them as includeFilters or excludeFiltersparameters of the @ComponentScan annotation (or as include-filter or exclude-filter sub-elements of the component-scan element). Each filter element requires the type and expression attributes. The following table describes the filtering options.

Filter Type	Example Expression	Description
annotation (default)	org.example.SomeAnnotation	An annotation to be present at the type level in target components.
assignable	org.example.SomeClass	A class (or interface) that the target components are assignable to (extend/implement).
aspectj	org.example..*Service+	An AspectJ type expression to be matched by the target components.
regex	org.example.Default.*	A regex expression to be matched by the target components class names.
custom	org.example.MyTypeFilter	A custom implementation of the org.springframework.core.type .TypeFilter interface.

 

The following example shows the configuration ignoring all @Repository annotations and using "stub" repositories instead.

@Configuration
@ComponentScan(basePackages = "org.example",
        includeFilters = @Filter(type = FilterType.REGEX, pattern = ".*Stub.*Repository"),
        excludeFilters = @Filter(Repository.class))
public class AppConfig {
    ...
}
