How do I specify multiple templateLoaderPaths for Freemarker in Spring Boot?

Question

I need to specify multiple template loader paths for FreeMarker in a Spring Boot web application but the FreeMarkerAutoConfigurationClass only let me specify one path using the spring.freemarker.templateLoaderPath property, which uses the setTemplateLoaderPath method in the FreeMarkerConfigurationFactory. However, this class allows me to set multiple path using the setTemplateLoaderPaths method. Which is the best way to override this auto-configuration class and specify multiple loader paths? I don't really understand well the Spring Java config classes and I want an example for this before write the code I need. I'm using Spring Boot 1.1.2. Thanks in advance.

You'll need to provide your own bean of type org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer with your desired configuration. To do so, add something similar to the following to one of your application's Java configuration classes:

@Bean
public FreeMarkerConfigurer freeMarkerConfigurer() {
    FreeMarkerConfigurer configurer = new FreeMarkerConfigurer();
    configurer.setTemplateLoaderPaths("one", "two", "three");

    // Apply further configuration as needed

    return configurer;
}

Update: the latest Spring Boot 1.2 snapshots now accept a comma-separated list for the spring.freemarker.templateLoaderPath property allowing you to specify multiple paths without declaring a custom FreeMarkerConfigurer bean.
