spring启动加载类,手动加载bean

方法一：

public final class Assembler implements BeanFactoryPostProcessor {

     private static ConfigurableListableBeanFactory beanFactory; // Spring应用上下文环境

     public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {

           Assembler.beanFactory = beanFactory;

           initMerchant();

     }

实现该接口，可以在spring的bean创建之前，修改bean的定义属性。

也就是说，Spring允许BeanFactoryPostProcessor在容器实例化任何其它bean之前读取配置元数据，并可以根据需要进行修改

手动注册bean：

 private static ConfigurableListableBeanFactory beanFactory; // Spring应用上下文环境

     DefaultListableBeanFactory beanFactory2 = (DefaultListableBeanFactory) beanFactory;

     BeanDefinitionBuilder beanMer = BeanDefinitionBuilder.genericBeanDefinition(className);

     beanMer.setParentName(beanType);

     beanMer.addPropertyValue("mrchCode", corgNum);

     beanMer.addPropertyValue("connectionName", beanName);

     beanMer.setInitMethodName("init");

     beanMer.setInitMethodName("isMerchantOpen");

     beanName = beanType + "_" + corgNum;

     beanFactory2.registerBeanDefinition(beanName, beanMer.getRawBeanDefinition());

方法二：

public class InitConfig extends HttpServlet implements ServletContextListener {

     @Override

     public void contextDestroyed(ServletContextEvent arg0) {

           logger.info("销毁。。。。");

           timer.cancel();

     }

     @Override

     public void contextInitialized(ServletContextEvent arg0) {

           logger.info("初始化。。。。");

            //手动让spring容器管理此类

          SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);

     }

  <listener>

    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

  </listener>

  <listener>

    <listener-class>jsfirst.weixin.InitConfig</listener-class>

  </listener>
