This version is still in development and is not considered stable yet. For the latest stable version, please use Spring Framework 6.1.12! |
Groovy Markup
The Groovy Markup Template Engine is primarily aimed at generating XML-like markup (XML, XHTML, HTML5, and others), but you can use it to generate any text-based content. The Spring Framework has a built-in integration for using Spring MVC with Groovy Markup.
The Groovy Markup Template engine requires Groovy 2.3.1+. |
Configuration
The following example shows how to configure the Groovy Markup Template Engine:
-
Java
-
Kotlin
@Configuration
@EnableWebMvc
public class WebConfig implements WebMvcConfigurer {
@Override
public void configureViewResolvers(ViewResolverRegistry registry) {
registry.groovy();
}
// Configure the Groovy Markup Template Engine...
@Bean
public GroovyMarkupConfigurer groovyMarkupConfigurer() {
GroovyMarkupConfigurer configurer = new GroovyMarkupConfigurer();
configurer.setResourceLoaderPath("/WEB-INF/");
return configurer;
}
}
@Configuration
@EnableWebMvc
class WebConfig : WebMvcConfigurer {
override fun configureViewResolvers(registry: ViewResolverRegistry) {
registry.groovy()
}
// Configure the Groovy Markup Template Engine...
@Bean
fun groovyMarkupConfigurer() = GroovyMarkupConfigurer().apply {
resourceLoaderPath = "/WEB-INF/"
}
}
The following example shows how to configure the same in XML:
<mvc:annotation-driven/>
<mvc:view-resolvers>
<mvc:groovy/>
</mvc:view-resolvers>
<!-- Configure the Groovy Markup Template Engine... -->
<mvc:groovy-configurer resource-loader-path="/WEB-INF/"/>
Example
Unlike traditional template engines, Groovy Markup relies on a DSL that uses a builder syntax. The following example shows a sample template for an HTML page:
yieldUnescaped '<!DOCTYPE html>'
html(lang:'en') {
head {
meta('http-equiv':'"Content-Type" content="text/html; charset=utf-8"')
title('My page')
}
body {
p('This is an example of HTML contents')
}
}
