How to get the request context in a freemaker template in spring

Question

How to get the request context path in freemarker template when using with spring?

My view resolver is like this

    <bean id="freeMarkerViewResolver" class="learn.common.web.view.FreemarkerViewResolver">         <property name="order" value="1" />         <property name="viewClass"         value="org.springframework.web.servlet.view.freemarker.FreeMarkerView" />         <property name="suffix" value=".ftl" />         <property name="cache" value="false" />     </bean> 

My view resolver learn.common.web.view.FreemarkerViewResolver extends org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver

Answer 1

In your view resolver you can add the following property

<property name="requestContextAttribute" value="rc"/> 

Then in your freemarker template you can get the request context patch like

${rc.getContextPath()} 

Answer 2

If your requirement is to fetch the Context Path in your FTL view then Spring provides a better alternate - First import spring.ftl in your view

<#import "/spring.ftl" as spring /> 

Then use macro @spring.url for the URL which you want to make context aware -

<li id="history"><a href="<@spring.url '/rest/server/taskHistory'/>">History</a></li> 

This is very much similar to -

<li id="history"><a href="${rc.getContextPath()}/rest/server/taskHistory">History</a></li> 

Where rc is defined in viewResolver

XML based configuration

<property name="requestContextAttribute" value="rc"/> 

or Spring Boot style configuration (aplication.yml)

spring.freemarker.request-context-attribute: rc
