java - How to load properties file from property file and database at the same time in Spring? -


i have app.properties file,which define database connection configuration such as

#datasource jdbc.driver=com.mysql.jdbc.driver jdbc.url=jdbc\:mysql\://localhost/test?useunicode\=true&characterencoding\=utf-8 jdbc.username= jdbc.password=

and place dynamic properties in database,load custom implementation of abstractfactorybean ,follow q&a https://stackoverflow.com/a/4601913

and applicationcontext.xml

<context:property-placeholder location="classpath:app.properties" order="1" /> <context:property-placeholder properties-ref="props" order="2"/>  <bean id="datasource" class="org.springframework.jdbc.datasource.simpledriverdatasource">     <property name="driverclass" value="${jdbc.driver}" />     .... </bean>

cannot find class [${jdbc.driver}].

how can make sure abstractfactorybean load properties first ?
