03-SpringBoot之WEB(一)——整合Freemarker與Thymeleaf
阿新 • • 發佈:2018-12-25
主要記錄 Spring Boot 與 Web 開發相關的知識,包括整合Freemarker 和 Thymeleaf。
1. 整合 Freemarker
1.1 新增Freemarker依賴
在pom.xml中新增Freemarker依賴,如下:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
1.2 新增 Freemarker 模板配置
在application.yml中spring節點下新增Freemarker配置,如下:
#freemarker 配置
freemarker:
allow-request-override: false
cache: true
check-template-location: true
charset: utf-8
content-type: text/html
expose-session-attributes: false
expose-spring-macro-helpers: false
expose-request-attributes : false
prefix:
suffix: .ftl
1.3 案例開發
新建controller包,在 controller 包中建立 FreemarkerController:
import com.springboot.web.model.User;
import com.springboot.web.utils.UUIDUtil;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
@Controller
public class FreemarkerController {
@RequestMapping("/freemarker")
public String hello(Map<String, Object> map) {
User u1 = new User(UUIDUtil.getUUID(), "張三", 23);
User u2 = new User(UUIDUtil.getUUID(), "李四", 28);
User u3 = new User(UUIDUtil.getUUID(), "王五", 25);
List<User> uList = new ArrayList<User>();
uList.add(u1);
uList.add(u2);
uList.add(u3);
map.put("uList", uList);
map.put("msg", "Hello Freemarker");
return "freemarker";
}
}
在 templates 目錄中建立名為 freemarker.ftl 檔案,內容如下:
<!DOCTYPE html>
<html lang="zh">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div class="container">
<h2>${msg}</h2>
<table border="2">
<tr>
<td>UUID</td>
<td>姓名</td>
<td>年齡</td>
</tr>
<#list uList as user>
<tr>
<td>${user.id}</td>
<td>${user.name}</td>
<td>${user.age}</td>
</tr>
</#list>
</table>
</div>
</body>
</html>
執行結果如下:
2. 整合 Thymeleaf
2.1 新增Thymeleaf依賴
在pom.xml中新增Thymeleaf依賴,如下:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
2.2 新增 thymeleaf 模板配置
在application.yml中spring節點下新增thymeleaf配置,如下:
#thymeleaf 配置
thymeleaf:
cache: true
prefix: classpath:/templates/
suffix: .html
mode: HTML5
encoding: UTF-8
servlet:
content-type: text/html
2.3 案例開發
新建controller包,在 controller 包中建立 ThymeleafController:
import com.springboot.web.model.User;
import com.springboot.web.utils.UUIDUtil;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
@Controller
public class ThymeleafController {
@RequestMapping("/thymeleaf")
public String hello(Map<String, Object> map) {
User u1 = new User(UUIDUtil.getUUID(), "張三", 23);
User u2 = new User(UUIDUtil.getUUID(), "李四", 28);
User u3 = new User(UUIDUtil.getUUID(), "王五", 25);
List<User> uList = new ArrayList<User>();
uList.add(u1);
uList.add(u2);
uList.add(u3);
map.put("uList", uList);
map.put("msg", "Hello Thymeleaf");
return "thymeleaf";
}
}
在 templates 目錄中建立名為 thymeleaf.html檔案,內容如下:
<!DOCTYPE html>
<html lang="zh">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div class="container">
<h2 th:text="${msg}"></h2>
<table border="2">
<tr>
<td>UUID</td>
<td>姓名</td>
<td>年齡</td>
</tr>
<tr th:each="user:${uList}">
<td th:text="${user.id}"></td>
<td th:text="${user.name}"></td>
<td th:text="${user.age}"></td>
</tr>
</table>
</div>
</body>
</html>
執行結果如下:
