spring2.5 引入资源文件的方式
?以前项目中引入 数据库 连接相关的字符串 都是使用
<bean id="propertyConfigurer" name="code"> <context:component-scan base-package="cn.xxt"><context:include-filter type="regex" expression=".action.*"/><context:include-filter type="regex" expression=".service.*"/> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Repository"/></context:component-scan>
?
后，今天无意中点到了 看到了dtd的提示 中有句 Note: You may use placeholders in package paths, but only resolved
against system properties (analogous to resource paths).
Element : component-scanScans the classpath for annotated components that will be auto-registered as Spring beans. By default, the Spring-provided @Component, @Repository, @Service, and @Controller stereotypes will be detected. Note: This tag implies the effects of the 'annotation-config' tag, activating @Required, @Autowired, @PostConstruct, @PreDestroy, @Resource, @PersistenceContext and @PersistenceUnit annotations in the component classes, which is usually desired for autodetected components (without external configuration). Turn off the 'annotation-config' attribute to deactivate this default behavior, for example in order to use custom BeanPostProcessor definitions for handling those annotations. Note: You may use placeholders in package paths, but only resolved against system properties (analogous to resource paths). A component scan results in new bean definition being registered; Spring's PropertyPlaceholderConfigurer will apply to those bean definitions just like to regular bean definitions, but it won't apply to the component scan settings themselves.Content Model : (include-filter*, exclude-filter*)

就网上搜索了一下
找到了 还能如下用
<context:property-placeholder location="classpath:frameworkconfig/jdbc/MySQL.properties"/>
?
然后试了如下组合，也能用 上面的
<context:annotation-config/>
