spring - How to pass a Map<String, String> with application.properties

Question

I have implemented some authorization in a webservice that needs be configured.

Currently the user/password combo is hardcoded into the bean configuration. I would like to configure the map with users and passwords into the application.properties so the configuration can be external.

Any clue on how this can be done?

<bean id="BasicAuthorizationInterceptor" class="com.test.BasicAuthAuthorizationInterceptor">
    <property name="users">
        <map>
            <entry key="test1" value="test1"/>
            <entry key="test2" value="test2"/>
        </map>
    </property>
</bean>

Answer 1

you can use @Value.

Properties file:

users={test1:'test1',test2:'test2'}

Java code:

@Value("#{${users}}")
private Map<String,String> users;
