可以先看这篇文章spring+mybatis整合
maven项目配置文件中在之前的基础上还需要加入springMVC相关依赖
可以去maven仓库https://mvnrepository.com/去找你需要的包
spring-mvc.xml
在配置文件中我设置了两种视图解析器（jsp,html）具体需要可以自行更改

css,js,img等静态资源的引用可以使用两种方法

<!-- 引入静态资源 -->
<mvc:annotation-driven />
<mvc:resources mapping="/css/**" location="/static/css/**" />
<mvc:resources mapping="/img/**" location="/static/img/**" />
<mvc:resources mapping="/js/**" location="/static/js/**" />
?
<!-- 第二中种在web.xml中添加 -->
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.js</url-pattern>
<url-pattern>*.png</url-pattern>
<url-pattern>*.css</url-pattern>
</servlet-mapping>
这是web下面的目录结构图
controller层
controller层接收前端参数一般使用json对象传递，在这里演示的是直接传递
LoginController 类
package com.controller;
import com.pojo.Root;
import com.service.RootServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class LoginController {
//注入service层实现类
@Autowired
@Qualifier("rootServiceImpl")
private RootServiceImpl rootService;
//前端请求接口方法 如果添加了@ResponseBody注解则不会走视图解析器而是直接返回字符串
@RequestMapping(value = "/login",method = RequestMethod.POST,produces = "application/json;charset=UTF-8")
public String login(String username,String password){
Root r1 = new Root(username, password);
Root r2 = rootService.select(new Root("root", "123456"));
if (r1.equals(r2)){
return "1";
}
//转发到test.html页面或者test.jsp
return "test";
}
}
index.html 使用form标签发送请求
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>登录</title>
<link rel="stylesheet" type="text/css" href="/static/css/index.css" />
</head>
<body>
<img class="bgone" src="/static/img/1.jpg" />
<img class="pic" src="/static/img/a.png" />
<div class="table">
<form method="post" action="/login">
<div class="wel">学生系统后台登录</div>
<div class="wel1">XUE SHENG XI TONG HUO TAI DENG LU</div>
<div class="user">
<div id="yonghu" style=""><img src="/static/img/yhm.png" /></div>
<input type="text" name="username" placeholder="用户名" />
</div>
<div class="password">
<div id="yonghu"><img src="/static/img/mm.png" /></div>
<input type="password" name="password" placeholder="密码"/>
</div>
<input class="btn" type="submit" name="登录" value="登录"/>
</form>
</div>
</body>
</html>
