Question

所以我在HomeController.java类中有Index动作。

我的免费标记模板：

/web-inf/ftl/test.ftl

如何加载模板？

我在appname-servlet.xml中有这个：

 <bean id="viewResolver"
          class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
        <property name="suffix">
            <value>.ftl</value>
        </property>
    </bean>

    <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
        <property name="templateLoaderPath" value="/WEB-INF/freemarker/"/>
    </bean>

我的操作代码对于HomeController索引操作应该是什么样的？

我有/web-inf/freemarker/index.ftl

Answer 1

我在spring-mvc demo webapp（spring 3.0.5）中使用了freemarker。见http://projectnotes.svn.sourceforge.net/viewvc/projectnotes/trunk/ Web控制器看起来像这样，因此当向index.html发出请求时，将呈现index.ftl（您将置于src / main / webapp / WEB-INF下）

@Controller
public class IndexController {

    @RequestMapping("/index.html")
    public String index(Map<String, Object> model) {

        // populate the model parameter if you need it in index.ftl   
        return "index";

    }
}

我的freemarker上下文文件如下所示

<?xml version="1.0" encoding="UTF-8"?>

Answer 2

根据blog上提供的操作示例，您的控制器应如下所示：

@Controller
public class MyController {

    @RequestMapping(value = "/index")
    public String home(Model model) {

            // Populate the model as necessary
            model.addAttribute("MsTime", System.currentTimeMillis());

            return "Home";

    }

}

带有spring mvc的freemarker的第一步
