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
<!-- 整合freemarker -->
<dependency>
<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
