我正在使用Spring开发一个Web应用程序，我只是在启动时使用了@PostConstruct和@Bean机制来调用一个函数。

public class MyCache<T> {
    @PostConstruct
    public void init() {
        System.out.println("inittttttttttt");
        // something
    }
}

@Configuration
@EnableScheduling
public class AppConfig {
    @Bean
    public MyCache<MyData> myCache() {
        return new MyCache<MyData>();
    }
}

public class TextFilter {
    private AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext();
    private MyCache<MyData> cache;

    public TextFilter() {
        this.context.scan("com.sensitive_words.utils");
        this.context.refresh();
        this.cache = this.context.getBean(MyCache.class);
    }

    public String filter(String originalText) {
        return this.cache.get().filter(originalText);
    }
}

如您所见，我创建了一个Bean并在类TextFilter中使用了该Bean。
但是，我发现函数init()执行了两次。
