springboot整合freemarker模板

Freemarker作用于表现层，能更好的实现mvc分离。

1、首先，在pom文件里加入freemarker依赖

　　<groupId>org.springframework.boot</groupId>

　　<artifactId>spring-boot-starter-freemarker</artifactId>

</dependency>

2、在配置文件application.properties中加入freemarker配置

# freemarker静态资源配置

# 设定ftl文件路径

spring.freemarker.tempalte-loader-path=classpath:/templates

# 关闭缓存，及时刷新，上线生产环境需要修改为true

spring.freemarker.cache=false

spring.freemarker.charset=UTF-8

spring.freemarker.check-template-location=true

spring.freemarker.content-type=text/html

spring.freemarker.expose-request-attributes=true

spring.freemarker.expose-session-attributes=true

spring.freemarker.request-context-attribute=request

spring.freemarker.suffix=.ftl

3、在public目录下建立freemarker文件夹

4、建立login.ftl文件

[#ftl]
<html>
    <head>
        <meta charset="GBK">
        <title>杭州天纵智能管理平台</title>
        <link rel="stylesheet" href="../css/layui.css" rel="stylesheet">
        <link rel="stylesheet" href="../css/modules/layer/default/layer.css?v=3.1.1" rel="stylesheet">
        <style>
        html,body{
            width: 100%;
            height: 100%;
            margin: 0;
            padding: 0;
        }
        body {
            display: flex;
            align-items: center; /*定义body的元素垂直居中*/
            justify-content: center; /*定义body的里的元素水平居中*/
        }
        </style>
    </head>
    <body>
        <form class="layui-form">
            <div class="layui-form-item">
                <label class="layui-form-label">用户名</label>
                <div class="layui-input-inline">
                    <input type="text" name="userName" lay-verify="required" autocomplete="off" placeholder="请输入用户名称" class="layui-input">
                </div>
            </div>
            <div class="layui-form-item">
                <label class="layui-form-label">密码</label>
                <div class="layui-input-inline">
                    <input type="password" name="passWord" lay-verify="required" autocomplete="off" placeholder="请输入密码" class="layui-input"/>
                </div>
            </div>
            <div class="layui-form-item">
                <label class="layui-form-label"></label>
                <div class="layui-input-inline">
                    <button type="submit" class="layui-btn" lay-submit="" lay-filter="demo1">登录</button>
                </div>
            </div>
        </form>
        <script src="../js/layui.js"></script>
        <script src="../js/jquery-1.12.4.js"></script>
        <script>
        layui.use(['form'], function(){
            var form = layui.form
                ,layer = layui.layer
        form.on('submit(demo1)', function(data){
            $.ajax({
                url: "/manage/login",
                type : "get",
                data: data.field,
                async: false,
                success: function(data){
                    if(data>0){
                        alert("登录成功");
                        window.location.href="/index.html";
                        event.preventDefault();
                    }else{
                        alert("登录失败");
                    }
                },
                error:function(XMLHttpRequest, textStatus, errorThrown){
                    alert(XMLHttpRequest.status);//状态码
                    alert(XMLHttpRequest.readyState);//状态
                    alert(textStatus);//错误信息
                }
            })
        });
        });
    </script>
    </body>
</html>

5、写controller方法

@RequestMapping(value = "/manage")

@Controller

public class login(){

　　@RequestMapping(value="login")

　　public String loginFtl(HttpServletRequest request, HttpServletResponse response){

　　　　return "/freemarker/login";

　　}

6、访问localhost:8080/manage/login
