java - 使用setApplicationContext出现运行错误，求解！

Answer 1

其實可以不用用到這個工具類，在需要getBean的类注入一个ApplicationContext即可。

@Autowired
private ApplicationContext context;

...

context.getBean("bean name");

java.lang.IllegalStateException: BeanFactory not initialized or already closed - call 'refresh' before accessing beans via the ApplicationContext

樓主的專案根本沒啟動成功吧，應該還有其它的錯誤訊息。仔細看上面的堆疊 listenerStop -> closeWebApplicationContext 這個錯誤是在停止Tomcat的時候發生的錯誤。

將datasource.xml中xsi補全了就好了。
