解决多线程无法通过@Autowired注入实例bean

import org.springframework.beans.BeansException;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.ApplicationContextAware;
    import org.springframework.stereotype.Component;
    
    //解决多线程 无法通过@Autowired注入bean
    @Component
    public class ApplicationContextPro implements ApplicationContextAware {
        //上下文对象实例
        private static ApplicationContext applicationContext; //applicationContext
        //生成get和set方法
        @Override
        public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
            this.applicationContext = applicationContext;
        }
        public static ApplicationContext getApplicationContext() {
            return applicationContext;
        }
        /**
         * 通过name获取 Bean.
         */
        public static Object getBean(String name) {
            return getApplicationContext().getBean(name);
        }
        /**
         * 通过class获取Bean
         */
        public static <T> T getBean(Class<T> clazz) {
            return getApplicationContext().getBean(clazz);
        }
        /**
         * 通过name,以及Clazz返回指定的Bean
         */
        public static <T> T getBean(String name, Class<T> clazz) {
            return getApplicationContext().getBean(name, clazz);
        }
    }

@Autowired 
    	private CsdnUrlService csdnUrlService = ApplicationContextPro.getBean(CsdnUrlService.class);  //注意这里的参数的接口

这里通过构造去调用所需要的方法
