Passing encrypted properties to spring context - spring

Question

I never seen this but I wondering if somebody has come across. Having a web server which access a database. I want to pass the database password encrypted and have spring context decrypting it before setting the datasource. I know the spring security can do some of this like using a salt file in the web server, etc.
The challenge here is that I don't want to give a clear user,password,url to the web server team. Just an encrypted password and have spring decrypted before using it.
Is there something like this already? I know I could code something but is it already done?
Thanks

Answer 1

By using an org.jasypt.properties.EncryptableProperties object, an application would be able to correctly read and use a .properties file like this:
datasource.driver=com.mysql.jdbc.Driver
datasource.url=jdbc:mysql://localhost/reportsdb
datasource.username=reportsUser
datasource.password=ENC(G6N718UuyPE5bHyWKyuLQSm02auQPUtm)
Note that the database password is encrypted (in fact, any other property could also be encrypted, be it related with database configuration or not).

I actually found exactly what I was looking for in this thread:

Here are the details from jasyp http://www.jasypt.org/spring3.html

This problem and solution to it is explained here..(link)
db.Properties.
#driverClassName=oracle.jdbc.driver.OracleDriver
#url=jdbc:oracle:thin:#localhost:1521:XE
#username=ITEM_INVENTORY
driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/ITEM_INVENTORY?zeroDateTimeBehavior=convertToNull
username=root
Encrypt db.Properties
##password=cGFzc3dvcmQ=
password=cm9vdA==
The spring beans configuration for the datasource would look like this
(here you may use only password part)
spring-beans.xml
<bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="db#[driverClassName]" />
<property name="url" value="db#[url]" />
<property name="username" value="db#[username]" />
<property name="password" value="encryptedDb#[password]" />
</bean>
<bean id="dbPropertyPlaceholder" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:db.properties</value>
</list>
</property>
<property name="placeholderPrefix" value="db#[" />
<property name="placeholderSuffix" value="]" />
</bean>
<bean id="encryptedDbPropertyPlaceholder" class="com.inventory.api.util.DecryptPropertyConfigurer">
<property name="locations">
<list>
<value>classpath:encryped_db.properties</value>
</list>
</property>
<property name="placeholderPrefix" value="encryptedDb#[" />
<property name="placeholderSuffix" value="]" />
</bean>
