spring 中从springcontext 中获取service对象

code:

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

/**
 * @author 12828
 * @description SpringCOntexxtUtil
 * @date 2022/08/06 09:58
 */
@Component
public class SpringContexxtUtil implements ApplicationContextAware {
    private static ApplicationContext applicationContext;

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

    public static ApplicationContext  SpringContexxtUtil() {
        return applicationContext;
    }
    public static Object getBean(String name){
        return applicationContext.getBean(name);
    }
    public static Object getBean(String name,Class requiredType){
        return applicationContext.getBean(name,requiredType);
    }

    public static Object containsBean(String name){
        return applicationContext.containsBean(name);
    }
    public static Object isSingleton(String name){
        return applicationContext.isSingleton(name);
    }
    public static Object getType(String name){
        return applicationContext.getType(name);
    }
    public static Object getAliases(String name) {
        return applicationContext.getAliases(name);
    }
}

use way ：

MailContoller mailContoller = (MailContoller) SpringContexxtUtil.getBean("mailContoller");
