*  整合Thymeleaf
 *  整合FreeMarker

一、整合Thymeleaf

1.1、添加依赖

<dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>

1.2、配置控制器

package cn.waggag.controller;
    
    import cn.waggag.pojo.User;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RestController;
    import org.springframework.web.servlet.ModelAndView;
    
    import java.util.ArrayList;
    import java.util.List;
    
    @RestController
    public class UserController {
    
        @GetMapping("/thymeleaf")
        public ModelAndView usersThymeleaf(){
            List<User> users = new ArrayList<>();
            users.add(new User("王港",23));
            users.add(new User("仲夏三十",23));
    
            ModelAndView modelAndView = new ModelAndView();
            modelAndView.addObject("users",users);
            modelAndView.setViewName("usersthymeleaf");
            System.out.println(users);
            return modelAndView;
        }
    
    }

1.3、在resources下创建templates目录，创建usersthymeleaf.html

<html lang="en" xmlns:th="http://www.thymeleaf.org">
    <head>
        <title>整合thymeleaf</title>
    </head>
    <body>
    <table border="1" align="center">
        <tr>
            <td>用户名</td>
            <td>密码</td>
        </tr>
        <tr th:each="user:${users}">
            <td th:text="${user.name}"></td>
            <td th:text="${user.age}"></td>
        </tr>
    </table>
    </body>
    </html>

1.4、运行结果

二、整合FreeMarker

2.1、添加依赖

<dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>

2.2、配置控制器

@GetMapping("/freemarker")
        public ModelAndView usersFreeMarker(){
            List<User> users = new ArrayList<>();
            users.add(new User("王港",23));
            users.add(new User("仲夏三十",23));
    
            ModelAndView modelAndView = new ModelAndView();
            modelAndView.addObject("users",users);
            modelAndView.setViewName("usersfreemarker");
            System.out.println(users);
            return modelAndView;
        }

2.3、在resources下创建templates目录，创建usersfreemarker.ftl

<html lang="en" xmlns:th="http://www.thymeleaf.org">
    <head>
        <title>整合FreeMarker</title>
    </head>
    <body>
    <table border="1" align="center">
        <tr>
            <td>用户名</td>
            <td>密码</td>
        </tr>
        <#if users ?? && (users?size>0)>
            <#list users as user>
                <tr>
                    <td>${user.name}</td>
                    <td>${user.age}</td>
                </tr>
            </#list>
        </#if>)
    </table>
    </body>
    </html>

2.4、测试结果

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM4MjY0OTk5_size_16_color_FFFFFF_t_70 1][]

注意：目前流行前后端分离技术，可以不需要整合试图技术，后端直接提供接口即可。
