how solve issue？

i found solution particular problem,just append ignore-unresolvable="true" each line.

<context:property-placeholder location="classpath:em-management.properties" ignore-unresolvable="true"/> <context:property-placeholder location="file:///opt/ass/swp/conf/platform.properties" ignore-unresolvable="true"/>
