springboot模板

1、thymeleaf模板

 

2.Freemarker模板

 

Thymeleaf模板

首先导入依赖

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

 Spring Boot官方文档建议在开发时将缓存关闭，那就在application.properties文件中加入下面这行

spring:
  thymeleaf:
    cache: true

 

user

package com.jt.springboot.entity;

import lombok.Data;

@Data
public class user {
    private Integer uid;
    private String uname;
    private String pwd;

    public user(Integer uid, String uname, String pwd) {
        this.uid = uid;
        this.uname = uname;
        this.pwd = pwd;
    }

    public user() {
    }
}

controller层

package com.jt.springboot.controller;


import com.jt.springboot.entity.user;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import java.util.ArrayList;
import java.util.List;

@Controller
@RequestMapping("/thymeleaf")
public class UserController {
    @RequestMapping("/list")
    public String hello(HttpServletRequest request){
        request.setAttribute("msg","传单个字符");
        List<user> userList=new ArrayList<>();
        userList.add(new user(1,"zs","123"));
        userList.add(new user(2,"ww","111"));
        userList.add(new user(3,"ss","222"));
        request.setAttribute("userList",userList);
        request.setAttribute("htmlStr","<span style='color:red' >转译html代码块</span>");
        return "list";
    }
}

 

list.html

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>thymeleaf模板介绍</title>
</head>
<body>
<div th:text="${msg}"></div>
</body>
</html>

html加入提示

<html xmlns:th="http://www.thymeleaf.org">

遍历
htlm页面

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>thymeleaf模板介绍</title>
</head>
<body>
<div th:text="${msg}"></div>
<table width="60%" border="1">
    <tr>
        <td>id</td>
        <td>用户名</td>
        <td>密码</td>
    </tr>
    <tr th:each="u : ${userList}">
        <td  th:text="${u.uid}"></td>
        <td  th:text="${u.uname}"></td>
        <td  th:text="${u.pwd}"></td>
    </tr>
</table>
<div th:utext="${htmlStr}"></div>
</body>
</html>

Freemarker模板

学习网站：http://freemarker.foofun.cn/
导入pom依赖

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

application.yml文件的默认配置

spring:
  thymeleaf:
    cache: false

  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/freemarker
  mvc:
    static-path-pattern: /static/**

list.ftl

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h2>取值</h2>
<h3>提供默认值</h3>
welcome 【${name!'未知'}】 to freemarker!

<h3>exists用在逻辑判断</h3>
<#if name?exists>
    ${name}
</#if>

<h2>条件</h2>
<#if sex=='girl'>
    女
<#elseif sex=='boy'>
    男
<#else>
    保密
</#if>

<h2>循环</h2>
<table border="1px" width="600px">
    <thead>
    <tr>
        <td>ID</td>
        <td>角色名</td>
        <td>描述</td>
    </tr>
    </thead>
    <tbody>
    <#list roles as role>
        <tr>
            <td>${role.rid}</td>
            <td>${role.roleName}</td>
            <td>${role.desc}</td>
        </tr>
    </#list>
    </tbody>
</table>

<h2>include</h2>
<#include 'foot.ftl'>

<h2>局部变量(assign)/全局变量(global)</h2>
<#assign ctx1>
    ${springMacroRequestContext.contextPath}
</#assign>

<#global ctx2>
    ${springMacroRequestContext.contextPath}
</#global>
a
${ctx1}和${ctx2}

RoleController
package com.jt.springboot.controller;


import com.jt.springboot.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;

@Controller
@RequestMapping("/freemarker")
public class RoleController {
    @RequestMapping("/role/list")
    public ModelAndView roleList(){
        ModelAndView mav = new ModelAndView();
        mav.setViewName("/list");

        mav.addObject("name",null);
        mav.addObject("sex","gay");
        List list = new ArrayList();
        list.add(new Role(1,"老板","做生意"));
