这段代码展示了如何在SpringBoot应用中自定义@ComponentScan，排除特定的过滤器，如PackageExcludeFilter,TypeExcludeFilter和AutoConfigurationExcludeFilter。同时在启动类中，通过@Import引入了PackageScanConfiguration，并且在@SpringBootApplication中排除了JpaRepositoriesAutoConfiguration的自动配置。

代码：

import org.springframework.boot.autoconfigure.AutoConfigurationExcludeFilter;
import org.springframework.boot.context.TypeExcludeFilter;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;
import org.springframework.context.annotation.ComponentScan.Filter;

@Configuration(
    proxyBeanMethods = false
)
@ComponentScan(
    basePackages = {"com.etoak"},
    excludeFilters = {@Filter(
    type = FilterType.CUSTOM,
    classes = {PackageExcludeFilter.class}
), @Filter(
    type = FilterType.CUSTOM,
    classes = {TypeExcludeFilter.class}
), @Filter(
    type = FilterType.CUSTOM,
    classes = {AutoConfigurationExcludeFilter.class}
)}
)
public class PackageScanConfiguration {
    public PackageScanConfiguration() {
    }
}

启动类中使用：

@SpringBootApplication(
    scanBasePackages = {},
    exclude = {JpaRepositoriesAutoConfiguration.class}
)
@Import({PackageScanConfiguration.class})
public class AppBootstrap {
    private static Boolean parallel = false;

    public AppBootstrap() {}

    public static void main(String[] args) {
         SpringApplication springApplication = new SpringApplication(new Class[]{AppBootstrap.class});
    }
}
