java - Spring PropertyPlaceholderConfigurer Issue to Load A Properties File -
i'm trying use external properties file populate of beans in spring application context configuration file. when don't use ${} properties , hardcode jpavendoradapter class property below, can see file loaded in log file. if u rely on properties file , use class="${jpa.vendor.adapter}" notation, cannot find class [${jpa.vendor.adapter}] bean name 'jpavendoradapter' defined in class path resource [spring/applicationcontext.xml]; exception. file definetly on classpath @ runtime, seems loaded after needed. i've tried using <contextroperty-placeholder/> approach, got same exception. i'm using spring version 3.2.2.release, ideas?
applicationcontext.xml

try replacing propertyplaceholderconfigurer bean declaration with
<context:property-placeholder location="classpath:/runtime/project.properties"/> the above must not work class attribute.
what can instead implement factorybean produces class type
<bean id="example" class="com.mycom.factory.jpavendoradapterfactory"> <property name="class" value="${jpa.vendor.adapter}"/> <property name="showsql" value="true" /> <property name="generateddl" value="true" /> <property name="databaseplatform" value="org.hibernate.dialect.oracledialect" /> </bean> i believe spring automatically call getobject() on bean , add returned object context. believe example name generated bean (not factory).
