How to concatenate two String beans in a configuration file in Spring 2.5

java, spring

Solution

Does this work?

<bean id="dir" class="java.lang.String">
    <constructor-arg value="c:/work/"
</bean>

<bean id="file" class="java.lang.String">
    <constructor-arg value="file.properties" />
</bean>

<bean id="path" factory-bean="dir" factory-method="concat">
    <constructor-arg ref="file"/>
</bean>

Notice the usage of `String.concat(java.lang.String)` method as `factory-method`.

But XML isn't really the best place for stuff like this, what about Java `@Configuration`?

@Configuration
public class Cfg {
    @Bean
    public String dir() {
        return "c:/work/";
    }

    @Bean
    public String file() {
        return "file.properties";
    }

    @Bean
    public String path() {
        return dir() + file();
    }
}
