Could not resolve placeholder 'IMAGE_SERVER_URL' in string value "${IMAGE_SERVER_URL}"

 

这种问题 在网上查的是说使用了重复的property-placeholder   可能是在别的xml 也用了property-placeholder   

 

 

 解决方法 加上  ignore-unresolvable="true"

 

 

Attribute : ignore-unresolvable
Specifies if failure to find the property value to replace a key should be ignored. Default is
 "false", meaning that this placeholder configurer will raise an exception if it cannot resolve a
 key. Set to "true" to allow the configurer to pass on the  key to any others in the context that
 have not yet visited the key in question.

 

 大概意思是 开启后 允许配置程序将密钥传递给上下文中的任何其他配置程序
