Groovy标记

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.spring-doc.cadn.net.cn

Groovy Markup Template 引擎需要 Groovy 2.3.1+。

配置

以下示例展示了如何配置Groovy Markup Template Engine：spring-doc.cadn.net.cn

@Configuration
public class WebConfiguration 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
class WebConfiguration : WebMvcConfigurer {

	override fun configureViewResolvers(registry: ViewResolverRegistry) {
		registry.groovy()
	}

	// Configure the Groovy Markup Template Engine...

	@Bean
	fun groovyMarkupConfigurer() = GroovyMarkupConfigurer().apply {
		resourceLoaderPath = "/WEB-INF/"
	}
}

<beans xmlns="http://www.springframework.org/schema/beans"
	   xmlns:mvc="http://www.springframework.org/schema/mvc"
	   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	   xsi:schemaLocation="

			http://www.springframework.org/schema/mvc
			https://www.springframework.org/schema/mvc/spring-mvc.xsd">

	<mvc:view-resolvers>
		<mvc:groovy/>
	</mvc:view-resolvers>

	<!-- Configure the Groovy Markup Template Engine... -->
	<mvc:groovy-configurer resource-loader-path="/WEB-INF/"/>

</beans>

示例

与传统的模板引擎不同，Groovy Markup 依赖于使用构建器语法的 DSL。下面的示例展示了一个 HTML 页面的样本模板：spring-doc.cadn.net.cn

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')
	}
}
