Creating advice:     advice object包含了所有需要添加到aspect的逻辑代码，因为Spring中的joinpoint model是基于method interception的，所以在spring中advice object是可以加载在method调用的范围内的。Spring支持以下集中比较基本的advice类型。 Advice types in spring Advice type Interface Descritpion Around org.aopalliance.intercept.MethodInterceptor Intercepts calls to the target method Before org.springframework.aop.BeforeAdvice org.springframework.aop.MethodBeforeAdvice   Called before the target method is invoked After org.springframework.aop.AfterReturningAdvice Called after the … Continue reading →

Package org.springframework.jmx * fixed NotificationListenerHolder to correctly handle multiple specified object names * added "allowEagerInit" property to MBeanExporter, for autodetecting lazy-init beans and FactoryBean-produced objects * added "environment" property to MBeanClientInterceptor and NotificationListenerRegistar, allowing for JMX env entries * added … Continue reading →

Spring 2.5 标注开发的简单例子   研究了很久新出的 Spring 2.5, 总算大致明白了如何用标注定义 Bean, 但是如何定义和注入类型为 java.lang.String 的 bean 仍然未解决, 希望得到高人帮助. 总的来看 Java EE 5 的标注开发方式开来是得到了大家的认可了. @Service 相当于定义 bean, 自动根据 bean 的类名生成一个首字母小写的 bean @Autowired 则是自动注入依赖的类, 它会在类路径中找成员对应的类/接口的实现类, 如果找到多个, 需要用 @Qualifier("chineseMan") 来指定对应的 bean 的 ID. 一定程度上大大简化了代码的编写, 例如一对一的 bean … Continue reading →
