spring boot获取注入的实例bean

之前实现的在spring boot里集成的工具类获取spring 注入的bean,期间出现很多问题，其中@configuartion一定要加。再是实现applicationContextAware接口！

@Configuration

public class BeanTools implements ApplicationContextAware {

private static ApplicationContext applicationContext;

public void setApplicationContext(ApplicationContext context) {

applicationContext = context;

}

public static Object getBean(Class classname) {

try{

Object _restTemplate = applicationContext.getBean(classname);

return _restTemplate;

}catch(Exception e){

return "";

}

}

public static void setApplicationContext1(ApplicationContext context) {

applicationContext = context;

}

}
