二、Freemarker的基本语法

1、application.yml


mybatis:
    mapper-locations: classpath:mappers/*xml
    type-aliases-package: com.xnx.spboot04.model
server:
    port: 8080
    servlet:
        context-path: /spboot04
spring:
    application:
        name: spboot04
    datasource:
        driver-class-name: com.mysql.jdbc.Driver
        name: defaultDataSource
        password: 123456
        url: jdbc:mysql://localhost:3306/t280?useUnicode=true&characterEncoding=UTF-8
        username: root
    freemarker:
        cache: false
        charset: utf-8
        expose-request-attributes: true
        expose-session-attributes: true
        suffix: .ftl
        template-loader-path: classpath:/templates/
    mvc:
        static-path-pattern: /static/**
#    resources:
#        static-locations: classpath:/static/# Ӧ�÷��� WEB ���ʶ˿�
pagehelper:
    reasonable: true
    supportMethodsArguments: true
    page-size-zero: true
    helper-dialect: mysql
logging:
    level:
        com.xnx.spboot04: debug

2、IndexController


package com.zhoujuan.spboot04.controller;
 
import com.zhoujuan.spboot04.entity.User;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
 
import java.util.Arrays;
 
/**
 * @author zhoujuan
 * @create 2022-11-01 17:45
 */
@Controller
public class IndexController {
//    @RequestMapping("/")
//    public ModelAndView index(){
        springmvc
//        ModelAndView mv = new ModelAndView();
//        mv.addObject("uname","aa");
//        mv.setViewName("index");
//        System.out.println("come in");
//        return mv;
//    }
 
    @RequestMapping("/")
    public String index(Model model){
        model.addAttribute("sex","mimi");
//        model.addAttribute("uname","aa");
        model.addAttribute("users", Arrays.asList(new User(1,"zs"),
                new User(2,"ls"),new User(3,"ww")));
        model.addAttribute("arr",new Integer[]{3,4,5,6,7,8,9});
        System.out.println("come in");
        return "index";
    }
}

3、head.ftl


<#assign ctx>
    ${springMacroRequestContext.contextPath}
</#assign>
 
<#global ctx2>
    ${springMacroRequestContext.contextPath}
</#global>

4、index.ftl


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title></title>
</head>
<body>
<h3>取值</h3>
<p>1.1提供默认值</p>
<#--当接收的参数不为空会报错。这个问题是需要避免的-->
<#--${uname}-->
<#--{uname !}-->
