Springboot 手动获取bean/getBean的工具类SpringUtil(主要用来获取prototype类型的组件)


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

@Component
public class SpringUtils implements ApplicationContextAware {
    private static ApplicationContext applicationContext;

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

    public static Object getObject(String id) {
        Object object = null;
        object = applicationContext.getBean(id);
        return object;
    }

    public static <T> T getObject(Class<T> tClass) {
        return applicationContext.getBean(tClass);
    }

    public static Object getBean(String tClass) {
        return applicationContext.getBean(tClass);
    }

    public <T> T getBean(Class<T> tClass) {
        return applicationContext.getBean(tClass);
    }
}
