xml零配置之根配置

根配置用于配置数据源,安全规则,ORM等等

这个

package org.springframework.source.config;

import static org.springframework.context.annotation.ComponentScan.Filter;

@ComponentScan(basePackageClasses = Application.class,excludeFilters = @Filter({Controller.class,Configuration.class}))
class ApplicationConfig {
	
	@Bean
	public static PropertyPlaceholderConfigurer propertyPlaceholderConfigurer() {
		PropertyPlaceholderConfigurer ppc = new PropertyPlaceholderConfigurer();
		ppc.setLocation(new ClassPathResource("/persistence.properties"));

	}
	
}

这个不是mvc4零配置的内容了,自己看看
