SpringBoot 排除一些包的注入

---

需求

在系统迭代的过程中，有一些 Controller 大批量的不再使用，或者有一些接口我们不想再提供给外界

---

一、使用 @ComponentScan

@SpringBootApplication(scanBasePackages = "com.zrb.excludeSomePkg")
@ComponentScan(
        basePackages = "com.zrb.excludeSomePkg",
        // 排除的过滤器
        excludeFilters = {
                @ComponentScan.Filter(type = FilterType.CUSTOM, classes = CustomExcludeFilter.class)
        }
)
public class SpringBootAnnoExample {

    public static void main(String[] args) {
        ConfigurableApplicationContext applicationContext = SpringApplication.run(SpringBootAnnoExample.class);
        Pk1Service bean1 = applicationContext.getBean(Pk1Service.class);
        Pk2Service bean2 = applicationContext.getBean(Pk2Service.class);
        System.out.println(bean2);
        System.out.println(bean1);
    }
}

public class CustomExcludeFilter implements TypeFilter {

    /**
     * 忽略pk1包下的所有类
     */
    @Override
    public boolean match(MetadataReader metadataReader, MetadataReaderFactory metadataReaderFactory) throws IOException {
        String className = metadataReader.getClassMetadata().getClassName();
        return className.startsWith("com.zrb.excludeSomePkg.pk1");
    }
}
