spring动态bean注册示例分享


            1.在一些特殊的场景中需要动态向spring注册bean2.spring版本2.5.6

复制代码 代码如下:public class ServiceServiceImpl implements ServiceService, ApplicationContextAware {

 @Override public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)   throws BeansException {  this.context = applicationContext; }

 public void addBeanService(Service service) throws BVSException {  if (!context.containsBean(service.getServiceName())) {   Class<?> serviceClass = getServiceClass(service.getClassName());   BeanDefinitionBuilder beanDefinitionBuilder = BeanDefinitionBuilder.genericBeanDefinition(serviceClass);   beanDefinitionBuilder.addPropertyValue("servicename", service.getServiceName());   registerBean(service.getServiceName(), beanDefinitionBuilder.getRawBeanDefinition());  }

 }

 /**  * @desc 向spring容器注册bean  * @param beanName  * @param beanDefinition  */ private void registerBean(String beanName, BeanDefinition beanDefinition) {  ConfigurableApplicationContext configurableApplicationContext = (ConfigurableApplicationContext) context;  BeanDefinitionRegistry beanDefinitonRegistry = (BeanDefinitionRegistry) configurableApplicationContext    .getBeanFactory();  beanDefinitonRegistry.registerBeanDefinition(beanName, beanDefinition); }

 /**  * @desc 根据类名查找class  * @param className  * @return  * @throws BVSException  */ private Class<?> getServiceClass(String className) throws BVSException {  try {   return Thread.currentThread().getContextClassLoader().loadClass(className);  } catch (ClassNotFoundException e) {   log.error("not found service class:" + className, e);   throw new BVSException("not found service class:" + className, e);  } }}
