在springboot使用websocket时mapper无法注入

直接上代码

package cn.ujoined.combined.utils;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;@Overridepublic void setApplicationContext(ApplicationContext applicationContext) throws BeansException {if (SpringUtils.applicationContext == null) {SpringUtils.applicationContext = applicationContext;}}public static ApplicationContext getApplicationContext() {return applicationContext;}//        根据namepublic static Object getBean(String name) {return getApplicationContext().getBean(name);}//        根据类型public static <T> T getBean(Class<T> clazz) {return getApplicationContext().getBean(clazz);}public static <T> T getBean(String name, Class<T> clazz) {return getApplicationContext().getBean(clazz);}
}
