創建公共Utils 類

1. ApplicationContextRegister

1. @Component
2. @Lazy(false)
3. public class ApplicationContextRegister implements ApplicationContextAware {
4. private static ApplicationContext APPLICATION_CONTEXT;
6. /**
7. * 設置spring上下文 * * @param applicationContext spring上下文 * @throws BeansException
8. */
10. @Override
11. public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
12. APPLICATION_CONTEXT = applicationContext;
13. }
15. public static ApplicationContext getApplicationContext() {
16. return APPLICATION_CONTEXT;
17. }
18. }

1. //websocket 使用service 層
2. ApplicationContext act = ApplicationContextRegister.getApplicationContext();
3. messagelogService=act.getBean(MessagelogService.class);
4. int resultlog = messagelogService.insertIntoMessagelog(messagelog);

即可使用到service裏的方法了！！

websocket 中使用Service層的方法
