Spring boot 下Freemarker的注解方式配置

<span style="font-size:18px;"><span style="color:#3333FF;">1.创建FreemarkerConfig使用@Configuration将Freemarker需要的配置注入</span>import javax.annotation.PostConstruct;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Configuration;<span style="color:#006600;">//import com.gstar.acp.portal.directive.article.ArticleDirective;//import com.gstar.acp.portal.directive.channel.ChannelListDirective;//import com.gstar.acp.portal.directive.content.ContentListDirective;</span>import freemarker.template.TemplateException;<span style="color:#009900;">/** * @author chenmd * */</span>@Configurationpublic class FreeMarkerConfig {    @Autowired    protected freemarker.template.Configuration configuration;    @Autowired    protected org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver resolver;    @Autowired    protected org.springframework.web.servlet.view.InternalResourceViewResolver springResolver;        @PostConstruct    public void  setSharedVariable(){        configuration.setDateFormat("yyyy/MM/dd");        configuration.setDateTimeFormat("yyyy-MM-dd HH:mm:ss");        <span style="color:#009900;">//下面三句配置的就是我自己的freemarker的自定义标签，在这里把标签注入到共享变量中去就可以在模板中直接调用了        //configuration.setSharedVariable("content_list", new ContentListDirective());        //configuration.setSharedVariable("article_list", new ArticleDirective());        //configuration.setSharedVariable("channel_list", new ChannelListDirective());</span>                        <span style="color:#009900;">/**         * setting配置         */</span>        try {            configuration.setSetting("template_update_delay", "1");            configuration.setSetting("default_encoding", "UTF-8");        } catch (TemplateException e) {            e.printStackTrace();        }                        <span style="color:#009900;">/**         * 配置Spring JSP的视图解析器         */</span>        springResolver.setPrefix("/XXX/");<span style="color:#009900;">//解析前缀后XXX路径下的jsp文件</span>        springResolver.setSuffix(".jsp");        springResolver.setOrder(1);                <span style="color:#33CC00;">/**         * 配置Freemarker视图解析器         */</span>        resolver.setSuffix(".html"); <span style="color:#009900;">//解析后缀为html的</span>        resolver.setCache(false); <span style="color:#009900;">//是否缓存模板</span>        resolver.setRequestContextAttribute("request"); <span style="color:#009900;">//为模板调用时，调用request对象的变量名</span>        resolver.setOrder(0);                           }        }</span>

（注：以上就是Freemarker用注解的方式替代了以前的使用XML配置文件繁琐的配置方式，至于在pom.xml中引入freemarker的依赖，可以百度搜索 maven spring boot freemarker，添加到自己的pom.xml依赖中去就可以了）

2.下面说描述下pom.xml中需要添加的freemarker的依赖

<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-freemarker</artifactId></dependency><pre name="code" class="html">        </dependencies>

OK，添加完依赖后更新maven project ，freemarker的配置就配置完成了，不用像以前一样配置繁琐的xml一大堆配置。
