how to use messages with freemarker in spring mvc?

问题:

In a .jsp I would use:

<fmt:message key="welcome.title"/>

to display a message from my messages.properties file.

How would I do this with freemarker ?

回答1:

Import Spring Macro

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

Then

<@spring.message "yourMessageKeyGoesHere"/>

But you need to register ResourceBundleMessageSource

<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
    <property name="basename" value="messages"/>
</bean>

Keep in mind MessageSource must be called messageSource

No, you don't have to import this manually in each template. You can set an auto_import property in your freemarker settings as showed below.

<bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
   ...

   <property name="freemarkerSettings">
        <props>
            <prop key="auto_import">spring.ftl as spring</prop>
        </props>
   </property>
</bean>

Others are fine answers. Providing java config as example for those that use that.

 @Bean(name = "freemarkerConfig")
public FreeMarkerConfigurer freemarkerConfig() {
    FreeMarkerConfigurer configurer = new FreeMarkerConfigurer();
    configurer.setTemplateLoaderPaths("/WEB-INF/views/", 'classpath:/templates');
    Map<String, Object> map = new HashMap<>();
    map.put("xml_escape", new XmlEscape());
    configurer.setFreemarkerVariables(map)
    def settings = new Properties()
    settings['auto_import']  =  'spring.ftl as spring,layout/application.ftl as l,/macros/meh.ftl as meh'
    configurer.setFreemarkerSettings(settings)
    log.info "returning freemarker config"
    return configurer;
}
