Configuring postgresql driver through Spring xml datasource

I've been trying to configure the connections made with a postgresql datasource declared in a xml Spring configuration file.

<bean id="myDataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.postgresql.Driver" />
<property name="url" value="jdbc:postgresql://localhost:5432/dbname" />
<property name="username" value="postgres" />
<property name="password" value="" />
<property name="socketTimeout" value="10"/>
</bean>


I know, I shouldn't be using the
DriverManagerDataSource
class from spring, (we will soon move to C3p0 or DBCP) because it's not a real pooling.
I'm trying to set the socketTimeout value of a postgresql connection ( described here https://jdbc.postgresql.org/documentation/head/connect.html ) but of course, "socketTimeout" is not a property of the datasource, so it doesn't work.

Is it possible to do this through the datasource xml's configuration ? Or should I do it somewhere else ? Because the data source manages the connection I don't think I'll be able to do a

props.setProperty("timeout",30);
Connection conn = DriverManager.getConnection(url, props);


Can I even do this with the DriverManagerDataSource ? I tried to search, but I didn't find anything usefull, as not a lot of people are really using it.

Answer

Thank you M. Deinum, I was able to find how. Actually, even knowing the property was named "connectionProperties", I didn't found a lot answers (maybe people rarely use it this way ?). So I'm posting it:

<bean id="myDataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="org.postgresql.Driver" />
        <property name="url" value="jdbc:postgresql://localhost:5432/dbname" />
        <property name="username" value="postgres" />
        <property name="password" value="" />
        <!--<property name="socketTimeout" value="10"/>-->

        <property name="connectionProperties">
            <props>
                <prop key="socketTimeout">10</prop>
            </props>
        </property>
   </bean>

If anyone has a better/more complete answer, I'll check it out ;)
