spring中获取bean的几种方式

1 .  通过spring提供的ContextLoader获取 

ApplicationContext context = ContextLoader.getCurrentWebApplicationContext();personSecurityService = (PersonSecurityService) context.getBean("personSecurityService");

2. 在线程中获取bean

通过继承ApplicationContextAware.java类来获取。注意：该类也需要在spring中注册

@Servicepublic class SpringApplicationContextHolder implements ApplicationContextAware {private static ApplicationContext context;@Overridepublic void setApplicationContext(ApplicationContext context)throws BeansException {SpringApplicationContextHolder.context = context;}public static Object getSpringBean(String beanName) {return context == null ? null : context.getBean(beanName);}public static String[] getBeanDefinitionNames() {return context.getBeanDefinitionNames();}}
