Question

I suppose that everybody that uses spring, uses form binding and validation. And you all defined the messages to display on validation errors. I did it with this in my config:

<bean id="messageSource"
        class="org.springframework.context.support.ResourceBundleMessageSource"
        p:basename="messages" />

what will happen basically is that it will read messages.properties in my root folder of the project.

But I’d need to put messages in two separate files. Because one part of the app has to be standalone. I tried adding this just after the one above:

<bean id="messageSourceAssistenza"
        class="org.springframework.context.support.ResourceBundleMessageSource"
        p:basename = "com.mypackage.other.assistenzamessages.properties"
        />

but it can’t resolve those messages at all. How to solve this?

Answer 1

You should be able to use ResourceBundleMessageSource.setBasenames that accepts array of base names:

Set an array of basenames, each
following ResourceBundle conventions:
essentially, a fully-qualified
classpath location. If it doesn’t
contain a package qualifier (such as
org.mypackage), it will be resolved
from the classpath root.

The associated resource bundles will
be checked sequentially when resolving
a message code. Note that message
definitions in a previous resource
bundle will override ones in a later
bundle, due to the sequential lookup.

Sample configuration as follows:

<bean id="messageSource"
    class="org.springframework.context.support.ResourceBundleMessageSource">
    <property name="basenames">
        <list>
            <value>messages_1</value>
            <value>messages_2</value>
            ...
            <value>messages_n</value>
        </list>
    </property>
</bean>
