类 PropertyPlaceholderConfigurer

java.lang.Object

org.springframework.core.io.support.PropertiesLoaderSupport

org.springframework.beans.factory.config.PropertyResourceConfigurer

org.springframework.beans.factory.config.PlaceholderConfigurerSupport

org.springframework.beans.factory.config.PropertyPlaceholderConfigurer

com.alibaba.otter.canal.instance.spring.support.PropertyPlaceholderConfigurer

所有已实现的接口:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.config.BeanFactoryPostProcessor, org.springframework.beans.factory.InitializingBean, org.springframework.context.ResourceLoaderAware, org.springframework.core.Ordered, org.springframework.core.PriorityOrdered

public class PropertyPlaceholderConfigurer
extends org.springframework.beans.factory.config.PropertyPlaceholderConfigurer
implements org.springframework.context.ResourceLoaderAware, org.springframework.beans.factory.InitializingBean

扩展Spring的 PropertyPlaceholderConfigurer ，增加默认值的功能。 例如：${placeholder:defaultValue}，假如placeholder的值不存在，则默认取得 defaultValue。

版本:

1.0.0
