Question

On my local machine I’m developing using a certain db (sql server), however, when I deploy to the development environment we are running mysql. So everytime before deploying I have to change certain properties in the config file. Properties pertaining to the datasource:

<bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://127.0.0.1:3306/mydb" />
    <property name="username" value="myuname" />
    <property name="password" value="mypwd"/>   
</bean>

Is there a way in spring mvc to have different config files for different environments? If so, how would I go about triggering the correct xml for the right environment.

Answer 1

spring mvc to have different config files for different environments?

we store database connection settings in a properties file in tomcat, each tomcat instalaltion then has its own specific db connection. Eg, a local dev box connects to the local DB server, the UAT server connects to UAT … and so on.

then in app context we have :

<context:property-placeholder location="file:${catalina.home}/conf/database_UAT.properties"
                                  ignore-unresolvable="true"/>

So where app gets deployed determines its DB connection.
