springBoot中如何获取bean信息呢?

下文笔者讲述SpringBoot中获取Spring容器中所有bean信息的方法分享,如下所示

SpringBoot获取bean信息的实现思路

通过实现ApplicationContextAware接口
    编写相关的实现类,即可获取Spring中的信息

例：获取SpringBoot中上下文及bean信息的工具类

 
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.context.annotation.Configuration;

@Configuration
public class SpringContextUtil implements ApplicationContextAware {
 
    private static ApplicationContext applicationContext;
 
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        SpringContextUtil.applicationContext = applicationContext;
    }
 
    public static ApplicationContext getCtx() {
        return SpringContextUtil.applicationContext;
    }
 
    public static <T> T getBean(Class<T> t) {
        return SpringContextUtil.applicationContext.getBean(t);
    }
}
