spring :硬编码注入bean实例

现在为减少配置文件进行手动编码注入：具体如下

public class TestRegisterBean {

public static void main(String[] args) {

ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext(
"applicationContext.xml");//在web环境下也可通过如下如方式获取
//WebApplicationContextUtils.getRequiredWebApplicationContext(servletContextEvent
.getServletContext());

DefaultListableBeanFactory beanFactory = (DefaultListableBeanFactory)

applicationContext.getBeanFactory();
GenericBeanDefinition messageSourceDefinition = new GenericBeanDefinition();

//参数参考上面配置文件里面 www.2cto.com
Map original = new HashMap();
original.put("basenames", "messages");
original.put("useCodeAsDefaultMessage", "true");
messageSourceDefinition.setBeanClass(ResourceBundleMessageSource.class);
messageSourceDefinition.setPropertyValues(new MutablePropertyValues(original));
//注册
beanFactory.registerBeanDefinition("ResourceBundleMessageSource",
messageSourceDefinition);
//获取
ResourceBundleMessageSource messageSource = (ResourceBundleMessageSource) applicationContext
.getBean("ResourceBundleMessageSource");
//测试
System.out.println(messageSource.getMessage("test", null, null));
}

}

测试本实例需在classpath下面创建messages_zh_CN.properties 并添加test。
