WebSocket中获取Spring的bean对象

新建工具类：

/**
 * <b>  </b>
 * <p>
 * 功能描述:解决注入的方式获取不到bean的情况
 * 
 * </p>
 * <p/>

 */
public class SpringUtil implements ApplicationContextAware {

    private static ApplicationContext applicationContext = null;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
       if(SpringUtil.applicationContext == null){
           SpringUtil.applicationContext  = applicationContext;
       }
    }
    //获取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);
    }

}

启动类中注入

/**
 * 启动类
 */
@ServletComponentScan
@SpringBootApplication
public class CustomerApplication {

    public static void main(String[] args) {
        SpringApplication.run(CustomerApplication.class, args);
    }


    /**
     * 注入springutil，用来特殊情况下获取bean
     * @return
     */
    @Bean
    public SpringUtil springUtil(){
        return new SpringUtil();
    }

}

websocket的handler中使用

  AuthService authService =  (AuthService) SpringUtil.getBean("authService");
