Grails3集成freemarker模板引擎
开发环境：
| Grails Version: 3.1.5
| Groovy Version: 2.4.6
| JVM Version: 1.8.0_141
1、创建grails项目
2、在build.gradle的dependencies中引入依赖
runtime "org.freemarker:freemarker:latest.release"
3、在grails-app/conf/spring/resources.groovy中注入dsl
import org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer
import org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver
// Place your Spring DSL code here
beans = {
freeMarkerConfigurer(FreeMarkerConfigurer) {
templateLoaderPath = "/"
}
viewResolver(FreeMarkerViewResolver) {
cache = "false"
prefix = "bin/freemarker"
suffix = ".ftl"
exposeSpringMacroHelpers = "true"
// requestContextAttribute = "request"
}
}
4、在src/main/weapp下创建test目录，目录下创建index.ftl
index.ftl
<!DOCTYPE html>
<html class="loginHtml">
<head>
<meta charset="utf-8">
<title>test</title>
</head>
<body>
用户名：${user!}
<br/>
系统版本：${os!}
<br/>
JDK版本：${java_version!}
<br/>
Tomcat版本：${tomcat_version!}
</body>
</html>
5、在controller下创建TestController
package test
import org.apache.catalina.util.ServerInfo
class TestController {
def index() {
// 传值方式一
//render view: "/test/index", model:[user: "test"]
// 传值方式二
request.setAttribute("user","test")
//获取操作系统名称
request.setAttribute("os",System.getProperty("os.name"))
//获取JDK版本
request.setAttribute("java_version",System.getProperty("java.version"))
//获取服务器版本
request.setAttribute("tomcat_version",request.getServletContext().getServerInfo())
request.setAttribute("tomcat_version",ServerInfo.getServerInfo())
render view: "/test/index"
}
}
6、启动项目，访问http://localhost/test/index
