一、问题
项目中需要公众号开发，移动端使用的是H5，但是如果不用前端框架的话，只能考虑JS前端用ajax解析JSON字符串了。今天我们就简单的说下前端框架Thymeleaf如何解决这个问题的；
二、开始实战
2.1：配置pom.xml
<!-- https://mvnrepository.com/artifact/org.thymeleaf/thymeleaf-spring4 --> <dependency> <groupId>org.thymeleaf</groupId> <artifactId>thymeleaf-spring4</artifactId> <version>3.0.9.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.thymeleaf/thymeleaf --> <dependency> <groupId>org.thymeleaf</groupId> <artifactId>thymeleaf</artifactId> <version>3.0.9.RELEASE</version> </dependency>
2.2：配置Spring mvc的主配置文件（spring-mvc.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" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 注解扫描包 --> <context:component-scan base-package="com.king.weixin"/> <!-- 开启注解 --> <mvc:annotation-driven/> <!-- 配置静态资源，直接映射到对应的文件夹，不被DispatcherServlet处理，3.04新增功能，需要重新设置spring-mvc-3.0.xsd --> <mvc:resources mapping="/img/**" location="/img/" /> <mvc:resources mapping="/js/**" location="/js/" /> <mvc:resources mapping="/css/**" location="/css/" /> <mvc:resources mapping="/html/**" location="/html/" /> <mvc:resources mapping="/tinymce/**" location="/tinymce/" /> <mvc:resources mapping="/upload/**" location="/upload/" /> <mvc:resources mapping="/assset/**" location="/assset/" /> <!-- 定义跳转的文件的前后缀 ，视图模式配置--> <!--采用前端模板工具thymeleaf--> <bean id="templateResolver" class="org.thymeleaf.spring4.templateresolver.SpringResourceTemplateResolver"> <property name="prefix" value="/html/" /> <property name="suffix" value=".html" /> <property name="templateMode" value="HTML5" /> <property name="cacheable" value="false" /> <property name="characterEncoding" value="UTF-8"/> </bean> <bean id="templateEngine" class="org.thymeleaf.spring4.SpringTemplateEngine"> <property name="templateResolver" ref="templateResolver" /> </bean> <bean class="org.thymeleaf.spring4.view.ThymeleafViewResolver"> <property name="templateEngine" ref="templateEngine" /> <property name="characterEncoding" value="UTF-8"/> </bean> <!--采用前端模板工具thymeleaf--> <!-- redis配置 --> <import resource="spring-redis.xml"/> </beans>
需要注意的是：下面的是关键配置
<mvc:resources mapping="/img/**" location="/img/" />
<mvc:resources mapping="/js/**" location="/js/" />
<mvc:resources mapping="/css/**" location="/css/" />
<mvc:resources mapping="/html/**" location="/html/" />
<mvc:resources mapping="/tinymce/**" location="/tinymce/" />
<mvc:resources mapping="/upload/**" location="/upload/" />
<mvc:resources mapping="/assset/**" location="/assset/" />
<!-- 定义跳转的文件的前后缀 ，视图模式配置-->
<!--采用前端模板工具thymeleaf-->
<bean id="templateResolver" class="org.thymeleaf.spring4.templateresolver.SpringResourceTemplateResolver">
<property name="prefix" value="/html/" />
<property name="suffix" value=".html" />
<property name="templateMode" value="HTML5" />
<property name="cacheable" value="false" />
<property name="characterEncoding" value="UTF-8"/>
</bean>
2.3：Controller配置
@RequestMapping(value = "/QueryUserbyOpenId", method = RequestMethod.GET) public String QueryUserbyOpenId(String openid,HttpServletRequest res,ModelMap model) { System.out.println("来了"); User user=new User(); user=userService.findByOpenId(openid); if(user!=null) { model.addAttribute("user_name", user.getUser_name()); model.addAttribute("user_sex",user.getUser_sex()); model.addAttribute("user_age", user.getUser_age()); model.addAttribute("user_address", user.getUser_address()); model.addAttribute("user_mobile", user.getUser_mobile()); } System.out.println("------------------:"+user.getUser_id()); return "userInfo";
return 返回的就是html视图的名称，具体是html还是jsp是在spring mvc中配置，需要在方法中生命ModelMap 来存放对象
2.4：HTML取值
<!DOCTYPE html> <html lang="en" xmlns:th="http://www.thymeleaf.org"> <head> <meta name="viewport" content="width=device-width, initial-scale=1" /> <meta charset="UTF-8"> <title>个人中心</title> <!-- <link rel="stylesheet" th:href="@{/css/userInfo.css}"> --> <link rel="stylesheet" href="../css/userInfo.css"> <script type="text/javascript" src="../js/jquery-3.3.1.min.js"></script> </head> <body> <div class="home"> <div class="doctor"> <div class="doctorName" th:text="${user_name}"></div> <img class="doctorImg" src="../assset/icon/mydoctor_man.png"> <div class="changeUserInfo" onclick="window.location.href='updateUserInfoHTML'"><img src="../assset/icon/[email protected]">修改个人信息</div> <div class="count"> <div> <span class="moneyCount">20元</span> <span>金额</span> </div> <div class="borderLeft"></div> <div> <span class="Upoint">0个</span> <span>U点</span> </div> <div class="borderRight"></div> <div> <span class="discount">0张</span> <span>优惠券</span> </div> </div> </div> <div class="msg"> <div>| 基本信息</div> <div class="msgDiv"> <span style="color: rgba(204,204,204,1)" >性别：</span><span th:text="${user_sex}"></span> </div> <div class="msgDiv"> <span style="color: rgba(204,204,204,1)">年龄：</span><span th:text=" ${user_age}"></span> </div> <div class="msgDiv"> <span style="color: rgba(204,204,204,1)">地址：</span><span th:text="${user_address}"></span> </div> <div class="msgDiv"> <span style="color: rgba(204,204,204,1)">手机：</span><span th:text="${user_mobile}"></span> </div> <!-- <div class="msgDiv"> --> <!-- <span style="color: rgba(204,204,204,1)">个人签名：</span><span th:text="${mobile}">无就是我</span> --> <!-- </div> --> <!-- <div class="msgDiv"> --> <!-- <span style="color: rgba(204,204,204,1)">手机号：</span><span th:text="${mobile}"></span> --> <!-- </div> --> <!-- <div class="changePhoneNum" onclick="window.location.href='updateUserMobileHTML'">修改手机号</div> --> </div> <!-- <div class="goToDownload" onclick="javascript:test()">马上下载APP,体验更多服务</div> --> </div> </body> <script type="text/javascript"> function test(){ window.location.href="download" } </script> </html>
导入命名空间 <html lang="en" xmlns:th="http://www.thymeleaf.org">，用th:text标签取值
