SpringBoot模板

Thymeleaf模板

 

相关pom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=false

对应的后台代码

package com.huang.springboot02.entity;

import lombok.Data;

/**
 * @auther 宇晨
 * @company
 * @create 2019-11-25-20:12
 */
@Data
public class User {
    private Integer uid;
    private String uname;
    private String pwd;

    public User() {
    }

    public User(Integer uid, String uname, String pwd) {
        this.uid = uid;
        this.uname = uname;
        this.pwd = pwd;
    }
}
package com.huang.springboot02.controller;

import com.huang.springboot02.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;

/**
 * @auther 宇晨
 * @company
 * @create 2019-11-25-20:16
 */
@Controller
@RequestMapping("/thymeleaf")
public class UserController {

    @RequestMapping("/list")
    public String hello(HttpServletRequest request){

        /**
         * 1、获取单个值
         * 2、能够在html页面进行遍历展示
         * 3、如何在html页面转义html代码块
         */
        request.setAttribute("msg","传输单个字符串！！！");
        List<User> userList = new ArrayList<>();
        userList.add(new User(1,"zs","123"));
        userList.add(new User(2,"ls","456"));
        userList.add(new User(3,"ww","789"));
        request.setAttribute("userList",userList);
        request.setAttribute("htmlStr","<span style='color:red' >转义html代码块<span>");

        return "list";
    }
}

前台HTML页面

 

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>thymeleaf模板知识点介绍</title>
</head>

Freemarker模板

导入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

 

 

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