java spring - override property value received from property file -

i have scenario, encoded password value property file. have own implementation of decryption, want decrypt password java class , want use decrypted value further, referred.

for example <bean id="mydatasource" class="org.apache.common.dbcp.basicdatasource" ... // more attributed set properties user, hostname etc. p:password="${mypropertey.password}" >

above code need implement below, specific password attribute, rest properties fine, password need decrypt before used.

(below implementation wrong, have mentioned give more , clear idea)

<bean id="mydatasource" class="org.apache.common.dbcp.basicdatasource" ... // more properties p:password="mydecryptbean.decryptmypassword(${mypropertey.password})" >

basically, need decrypt password, property file, before used establish database connection.

thanks time , !!

since using spring highly recommend looking propertyresourceconfigurer class. see official documentation.

in particular take @ convertproperty(string propertyname, string propertyvalue) method , consider creating class overrides it. able add in custom decryption logic overriden method, run every time spring accesses property.

directly documentation:

allows configuration of individual bean property values property resource, i.e. properties file. useful custom config files ... override bean properties configured in application context.
