反射生成对象，spring注入无效

反射类似于new出来的对象，不在spring容器中，所以spring的注解全都无效，当然包括事物@Transactional！

也可以通过代码的方式从applicationContext中取出需要注入的属性

Service service = (Service) SpringContextUtil.getBean("service");

注意：要放在方法中，不要声明为成员变量，否则启动程序时会实例化失败报异常的

spring配置

放上工具类：

public class SpringContextUtil implements ApplicationContextAware {
	private static ApplicationContext applicationContext; // Spring应用上下文环境

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

	public static ApplicationContext getApplicationContext() {
		return applicationContext;
	}

	public static Object getBean(String name) throws BeansException {
		return applicationContext.getBean(name);
	}

	public static Object getBean(String name, Class requiredType)
			throws BeansException {
		return applicationContext.getBean(name, requiredType);
	}

	public static boolean containsBean(String name) {
		return applicationContext.containsBean(name);
	}

	public static boolean isSingleton(String name)
			throws NoSuchBeanDefinitionException {
		return applicationContext.isSingleton(name);
	}

	public static Class getType(String name)
			throws NoSuchBeanDefinitionException {
		return applicationContext.getType(name);
	}

	public static String[] getAliases(String name)
			throws NoSuchBeanDefinitionException {
		return applicationContext.getAliases(name);
	}
}
