获取配置类中的JavaBean(@Bean修饰的函数返回值)对象

某一个配置类

@Configuration
public class EhcacheConfig {

    @Bean
    public EhCacheManagerFactoryBean cacheManagerFactoryBean(){
        EhCacheManagerFactoryBean ehCacheManagerFactoryBean = new EhCacheManagerFactoryBean();
        ehCacheManagerFactoryBean.setConfigLocation(new ClassPathResource("ehcache.xml"));
        ehCacheManagerFactoryBean.setShared(true);
        return  ehCacheManagerFactoryBean;
    }

    @Bean
    public EhCacheCacheManager ehCacheCacheManager(EhCacheManagerFactoryBean bean){
        return  new EhCacheCacheManager(bean.getObject());
    }
}

获取上面定义的 EhCacheManagerFactoryBean 类

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestAttributes;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;


@Component
public class ApplicationContextUtils  implements ApplicationContextAware {

    private static ApplicationContext  applicationContext = null ;

    
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    
    public static  T getBean(String beanName) {
        return (T) applicationContext.getBean(beanName);
    }


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

   

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