Thymeleaf模板

关于Thymeleaf的优点，我只说一条：它就是html页面。

Thymeleaf的pom依赖

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

工程目录：

Spring Boot官方文档建议在开发时将缓存关闭，在application.yml中加：

spring:
  thymeleaf:
      ache=false:

后台代码：

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;\'>这个是html标签</span>");
        ma.addObject("name","ls");

        //跳页面
        ma.setViewName("list");
        return ma;
    }
}

user

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;
    }
}

html

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Thymeleaf</title>
</head>
<body>
Thymeleaf
<h2>显示文本</h2>
<span th:text="${name}"></span>

<h2>显示HTML</h2>
<div th:utext="${msg}"></div>
<h2>循环</h2>
<table>
    <tr>
        <td>用户id</td>
        <td>用户民</td>
    </tr>
    <tr th:each="u:${userList}">
        <td th:text="${u.uid}"></td>
        <td th:text="${u.uname}"></td>
    </tr>
</table>

<h2>包含页面</h2>
<div th:include="role/common/head2"></div>


<h2>包含页面</h2>
<div th:include="role/common/head2 ::h3"></div>
</body>
</html>

head2.html

<div th:fragment="h1">
    第一部分内容
</div>
<div th:fragment="h2">
    第二部分内容
</div>
<div th:fragment="h3">
    第三部分内容
</div>

结果：

Freemarker模板

pom依赖

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

<!--可以不加，但是做项目的时候可能会用-->
 <resources>
            <!--解决mybatis-generator-maven-plugin运行时没有将XxxMapper.xml文件放入target文件夹的问题-->
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <!--freemarker模板也读取需要注释标红地方-->
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <!--<include>*.properties</include>-->
                    <!--<include>*.xml</include>-->
                    <!--<include>*.yml</include>-->
                </includes>
            </resource>
        </resources>

application.yml文件的默认配置

 freemarker:
    # 设置模板后缀名
    suffix: .ftl
    # 设置文档类型
    content-type: text/html
    # 设置页面编码格式
    charset: UTF-8
    # 设置页面缓存
    cache: false
    # 设置ftl文件路径，默认是/templates，为演示效果添加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","双11");
        List list = new ArrayList();
        list.add(new Role("1","1号用户"));
        list.add(new Role("2","2号用户"));
        list.add(new Role("3","3号用户"));
        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>获取值</h2>
${loginName!\'未知\'}

<h2>遍历</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>包含页面</h2>
<#include \'common/head.ftl\' />
<#include \'common/global.ftl\' />

<h2>获取项目名</h2>
${springMacroRequestContext.contextPath}

${ctx}

<h2>如何在页面定义变量</h2>
<#assign ctx1>
    ${springMacroRequestContext.contextPath}
</#assign>
${ctx1}
</body>
</html>

global.ftl

<#global ctx>
    ${springMacroRequestContext.contextPath}
</#global>

head.ftl

<!DOCTYPE html>
<html lang="en">

    <meta charset="UTF-8">
