freemarker tag usage and configuration

Create a freemarker configuration,Web.xmlLoad

Create springmvc-freemarker.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd" default-lazy-init="true"> <!-- To configure freeMarker Template Path --> <bean> <property name="templateLoaderPath" value="WEB-INF/web/templates/" /> <property name="defaultEncoding" value="UTF-8" /> <property name="freemarkerSettings"> <props> <prop key="template_update_delay">10</prop> <prop key="locale">zh_CN</prop> <prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop> <prop key="date_format">yyyy-MM-dd</prop> <prop key="number_format">#.##</prop> <prop key="tag_syntax">auto_detect</prop> </props> </property> <!-- Suppose you need to use freemarker Custom label, you need to add this section here --> <property name="freemarkerVariables"> <map> <entry key="imgResUrl" value-ref="img_res_url" /> </map> </property> </bean> <!-- Custom Label Access Path --> <bean id="img_res_url"> <property name="tagType" value="imgResUrl" /> </bean> <!-- freemarker view resolver --> <bean> <property name="contentType" value="text/html;charset=UTF-8" /> <!-- The value of this variable is pageContext.request, How to use the page: rc.contextPath --> <property name="requestContextAttribute" value="rc" /> </bean> </beans>

<property name="templateLoaderPath" value="WEB-INF/web/templates/" /> //The value represents the html returned by the controller, the path of the default prefix <prop key="tag_syntax">auto_detect</prop> // tag_syntax stands for html page rendering when the tag uses the [#if] mode, and there is also a < #if> mode that the individual finds [#if] useful because it does not conflict with html tags. <property name="freemarkerVariables"> <map> <entry key="imgResUrl" value-ref="img_res_url" /> </map> </property> //key="imgResUrl" indicates the name of the page custom label //value-ref="img_res_url "Custom Label Access Path" <bean id="img_res_url"> <property name="tagType" value="imgResUrl" /> </bean> id="img_res_url" //That's value-ref="img_res_url "link-down" //Represents a class accessed by a custom label within which the role of the label can be configured <property name="tagType" value="imgResUrl" /> //Indicates that the name of this label is imgResUrl

Create a configuration file,common.properties

##Picture Path img_res_url=/images/resources

package com.icbc.app.freemarker; import java.io.IOException; import java.io.Writer; import java.util.ArrayList; import java.util.List; import java.util.Map; import com.icbc.app.common.utils.CmsUtils; import com.icbc.app.constants.Constants; import com.icbc.app.constants.Constants.Tag; import com.icbc.app.web.utils.AppConfig; import freemarker.core.Environment; import freemarker.template.ObjectWrapper; import freemarker.template.SimpleSequence; import freemarker.template.TemplateDirectiveBody; import freemarker.template.TemplateDirectiveModel; import freemarker.template.TemplateException; import freemarker.template.TemplateModel; public class CmsCommonDirective implements TemplateDirectiveModel { private String tagType = null; @SuppressWarnings("rawtypes") @Override public void execute(Environment env, Map params, TemplateModel[] loopVars, TemplateDirectiveBody body)throws TemplateException, IOException { if (Tag.IMG_RES_URL.equals(tagType))//Picture Path Tag.IMG_RES_URL s are defined in a constant pool { try { renderImgResUrl(env, params, loopVars, body); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } } @SuppressWarnings("rawtypes") private void renderImgResUrl(Environment env, Map params, TemplateModel[] loopVars, TemplateDirectiveBody body) throws Exception { Writer out = env.getOut(); AppConfig loader = new AppConfig(); out.write(loader.getPropertiesByName("img_res_url"));//Get the picture prefix path in the profile and set the value of the label to the value set by properties } public String getTagType() { return tagType; } public void setTagType(String tagType) { this.tagType = tagType; } }

Create controller

package com.icbc.app.controller; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import com.icbc.app.web.utils.FrontUtils; /** * * @ClassName: LoginController * @Description:TODO * @author: He Junhui * @date: 2017 July 4, 2001, 10:48:12 * * @Copyright: 2017 * */ @Controller public class MemberController { private final Log logger = LogFactory.getLog(this.getClass()); private static final String ICBC_INDEX = "index.html"; /** * Home page GET * @Title: icbcLogin_GET * @Description: TODO Accessing a page requires first accessing the controller's get method, which returns the page * @param: @param request * @param: @param response * @param: @param model * @param: @return * @return: String * @throws */ @RequestMapping(value="/icbc/index.htm",method = RequestMethod.GET) public String icbcIndex_GET(HttpServletRequest request,HttpServletResponse response,ModelMap model,String userId,String time) { model.addAttribute("test1","test1"); return FrontUtils.findFrontTpl(request, response, model, ICBC_INDEX); } }
