property placeholder - @Value in my spring controller does not work -

my controller has

@value("${myprop}") private string myprop;  @bean public static propertysourcesplaceholderconfigurer propertyconfigindev() {     return new propertysourcesplaceholderconfigurer(); }  @requestmapping(value = "myprop", method = requestmethod.get) public @responsebody string getmyprop(){     return "the prop is:" + myprop; } 

my applicationcontext.xml has

<bean id="appconfigproperties" class="org.springframework.context.support.propertysourcesplaceholderconfigurer">     <property name="location" value="classpath:myapps-local.properties" /> </bean> 

i following exception:

caused by: java.lang.illegalargumentexception: not resolve placeholder 'myprop' in string value "${myprop}"

note: properties file myapps-local.properties in classpath , contains myprop=delightful

any great....

in xml based configuration need use propertyplaceholderconfigurer bean

<beans xmlns="http://www.springframework.org/schema/beans" . . . >   . . .     <bean class="org.springframework.beans.factory.config.propertyplaceholderconfigurer">         <property name="location" value="classpath:database.properties" />     </bean>   . . . </beans> 

but can use values database.properties in xml configuration only

<beans xmlns="http://www.springframework.org/schema/beans" . . >   . . .     <bean id="datasource" class="org.springframework.jdbc.datasource.drivermanagerdatasource">         <property name="driverclassname" value="${jdbc.driverclassname}" />         <property name="url" value="${jdbc.url}" />         <property name="username" value="${jdbc.username}" />         <property name="password" value="${jdbc.password}" />     </bean>   . . . </beans> 

if want use values properties files inside @value annotation bean's fields, need add @confuguration , @propertysource annotation bean class. this

@configuration @propertysource("classpath:database.properties") public class appconfig {      @value("${jdbc.url}")     private string url;      @bean     public static propertysourcesplaceholderconfigurer propertyconfigindev() {         return new propertysourcesplaceholderconfigurer();     } }
