SpringContextHolder实现ApplicationContextAware接口获取spring管理的上下文信息

package com.kindo.uas.common.config;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.context.annotation.Lazy;
import org.springframework.stereotype.Component;

@Component
@Lazy(false)
public class SpringContextHolder implements ApplicationContextAware {

    private static ApplicationContext applicationContext;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        SpringContextHolder.applicationContext = applicationContext;
    }

    public static ApplicationContext getApplicationContext() {
        assertApplicationContext();
        return applicationContext;
    }

    @SuppressWarnings("unchecked")
    public static  T getBean(String beanName) {
        assertApplicationContext();
        return (T) applicationContext.getBean(beanName);
    }

    public static  T getBean(Class requiredType) {
        assertApplicationContext();
        return applicationContext.getBean(requiredType);
    }

    private static void assertApplicationContext() {
        if (SpringContextHolder.applicationContext == null) {
            throw new RuntimeException("applicaitonContext属性为null,请检查是否注入了SpringContextHolder!");
        }
    }
}

这个是bean服务类：

@Service("zjjxASynthService")
public class IZjjxASynthServiceImpl implements IZjjxASynthService {
	//
}

获取对象信息：

public void receiveMessage2(String jsonMsg){
        ReentrantLock lock=new ReentrantLock();
        lock.lock();
        try{
            log.info("[开始消费REDIS消息队列数据，同步病案首页数据...]"+jsonMsg);
            Object  obj= SpringContextHolder.getBean("zjjxASynthService");
            Class z=obj.getClass();
            Method m = z.getDeclaredMethod("implement");
            m.invoke(obj);
            System.out.println(jsonMsg);
            log.info("[消费REDIS消息队列数据，同步病案首页数据成功.]"+jsonMsg);
        }catch (Exception e) {
            log.error("[消费REDIS消息队列数据同步病案首页数据失败，失败信息:{}]", e);
        }finally {
            lock.unlock();
        }
        latch.countDown();
    }
