Thymeleaf模板
關於Thymeleaf的優勢，我只說一條：它就是html頁面。html
Thymeleaf的pom依賴java
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
工程目錄：web
Spring Boot官方文檔建議在開發時將緩存關閉，在application.yml中加：spring
spring: thymeleaf: ache=false:
後臺代碼：緩存
package com.cjh.springboot01.Controller; import com.cjh.springboot01.entity.User; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import java.util.ArrayList; import java.util.List; /** * @author * @site * @company * @create 2019-11-08 11:05 */ @Controller @RequestMapping("/thymeleaf") public class ThymeleafController { @RequestMapping("/list") public ModelAndView list(){ ModelAndView ma= new ModelAndView(); List list = new ArrayList(); list.add(new User("1","zs")); list.add(new User("2","ls")); list.add(new User("3","ww")); ma.addObject("userList",list); ma.addObject("msg","<span style = 'color:red;'>這個是html標籤</span>"); ma.addObject("name","ls"); //跳頁面 ma.setViewName("list"); return ma; } }
userspringboot
package com.cjh.springboot01.entity; import lombok.Data; /** * @author * @site * @company * @create 2019-11-08 11:17 */ @Data public class User { private String uid; private String uname; public User() { } public User(String uid, String uname) { this.uid = uid; this.uname = uname; } }
htmlmybatis
<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>Thymeleaf</title> </head> <body> Thymeleaf <h2>顯示文本</h2> <span th:text="${name}"></span> <h2>顯示HTML</h2> <div th:utext="${msg}"></div> <h2>循環</h2> <table> <tr> <td>用戶id</td> <td>用戶民</td> </tr> <tr th:each="u:${userList}"> <td th:text="${u.uid}"></td> <td th:text="${u.uname}"></td> </tr> </table> <h2>包含頁面</h2> <div th:include="role/common/head2"></div> <h2>包含頁面</h2> <div th:include="role/common/head2 ::h3"></div> </body> </html>
head2.htmlmvc
<div th:fragment="h1"> 第一部份內容 </div> <div th:fragment="h2"> 第二部份內容 </div> <div th:fragment="h3"> 第三部份內容 </div>
結果：app
Freemarker模板
pom依賴maven
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
<!--能夠不加，可是作項目的時候可能會用-->
<resources>
<!--解決mybatis-generator-maven-plugin運行時沒有將XxxMapper.xml文件放入target文件夾的問題-->
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include> </includes> </resource> <!--freemarker模板也讀取須要註釋標紅地方--> <resource> <directory>src/main/resources</directory> <includes> <!--<include>*.properties</include>--> <!--<include>*.xml</include>--> <!--<include>*.yml</include>--> </includes> </resource> </resources>
application.yml文件的默認配置
freemarker: # 設置模板後綴名 suffix: .ftl # 設置文檔類型 content-type: text/html # 設置頁面編碼格式 charset: UTF-8 # 設置頁面緩存 cache: false # 設置ftl文件路徑，默認是/templates，爲演示效果添加role template-loader-path: classpath:/templates/role mvc: static-path-pattern: /static/**
controller
package com.cjh.springboot01.Controller; import com.cjh.springboot01.entity.Role; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import java.util.ArrayList; import java.util.List; /** * @author * @site * @company * @create 2019-11-08 11:37 */ @Controller @RequestMapping("/freemarker") public class FreemarkerController { @RequestMapping("/list") public ModelAndView list(){ ModelAndView mv = new ModelAndView(); mv.addObject("loginName","雙11"); List list = new ArrayList(); list.add(new Role("1","1號用戶")); list.add(new Role("2","2號用戶")); list.add(new Role("3","3號用戶")); mv.addObject("roleList",list); mv.setViewName("list"); return mv; } }
role
package com.cjh.springboot01.entity; import lombok.Data; /** * @author * @site * @company * @create 2019-11-08 11:42 */ @Data public class Role { private String rid; private String rname; public Role() { } public Role(String rid, String rname) { this.rid = rid; this.rname = rname; } }
html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Freemarker</title> </head> <body> Freemarker <h2>獲取值</h2> ${loginName!'未知'} <h2>遍歷</h2> <table border="1px" width="60%"> <tr> <td>角色id</td> <td>角色名</td> </tr> <#list roleList as role> <tr> <td>${role.rid}</td> <td>${role.rname}</td> </tr> </#list> </table> <h2>包含頁面</h2> <#include 'common/head.ftl' /> <#include 'common/global.ftl' /> <h2>獲取項目名</h2> ${springMacroRequestContext.contextPath} ${ctx} <h2>如何在頁面定義變量</h2> <#assign ctx1> ${springMacroRequestContext.contextPath} </#assign> ${ctx1} </body> </html>
