[java] view plain copy

print?

1. @Service
2. public class SpringManager implements ApplicationListener<ContextRefreshedEvent> {
3. private static ApplicationContext applicationContext = null;
4. @Override
5. public void onApplicationEvent(ContextRefreshedEvent event) {
6. if(applicationContext == null){
7. applicationContext = event.getApplicationContext();
8. }
9. }
10. /*ApplicationContext context= ContextLoader.getCurrentWebApplicationContext();//尝试下这个方法*/
11. public static ApplicationContext getApplicationContext() {
12. return applicationContext;
13. }
14. }

@Servicepublic class SpringManager implements ApplicationListener<ContextRefreshedEvent> {    private static ApplicationContext applicationContext = null;    @Override    public void onApplicationEvent(ContextRefreshedEvent event) {        if(applicationContext == null){            applicationContext = event.getApplicationContext();        }    }    /*ApplicationContext context= ContextLoader.getCurrentWebApplicationContext();//尝试下这个方法*/    public static ApplicationContext getApplicationContext() {        return applicationContext;    }}

[java] view plain copy

print?

1. 或者
2. @Service
3. public class SpringTool implements ApplicationContextAware {
4. private static ApplicationContext context = null;
5. @Override
6. public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
7. context = applicationContext;
8. }
9. public static ApplicationContext getApplicationContext() {
10. return context;
11. }
12. }

或者@Servicepublic class SpringTool implements ApplicationContextAware {    private static ApplicationContext context = null;    @Override    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {        context = applicationContext;    }    public static ApplicationContext getApplicationContext() {        return context;    }}
