如何注入ApplicationContext本身

import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

@Component
public class ApplicationContextProvider implements ApplicationContextAware {

    private static ApplicationContext context;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) {
        context = applicationContext;
    }

    public static ApplicationContext getContext() {
        return context;
    }
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.stereotype.Component;

@Component
public class ApplicationContextProvider {

    @Autowired
    private ApplicationContext context;

    public ApplicationContext getContext() {
        return context;
    }
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;

@Component
public class ApplicationContextProvider {

    @Autowired
    private ApplicationContext context;

    @PostConstruct
    public void init() {
        // 确保在Spring容器初始化完成后获取ApplicationContext实例
        System.out.println(context);
    }

    public ApplicationContext getContext() {
        return context;
    }
}
