创建项目

从App的main方法启动

package com.zhongruan;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.Component;

@SpringBootApplication
@MapperScan("com.zhongruan.dao")
public class App {
public static void main(String[] args){
SpringApplication.run(App.class,args);
}
}

导入jar包于pom.xml

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>


<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.1.1</version>
</dependency>

<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>

<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.0.9</version>
</dependency>

项目内容

controller 层 UserInfoController.java :

package com.zhongruan.controller;

import com.zhongruan.bean.UserInfo;
import com.zhongruan.dao.IUserInfoDao;
import com.zhongruan.service.IUserInfoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("user")
public class UserInfoController {
@Autowired
private IUserInfoService userInfoService;

@RequestMapping("toAdd.do")
public String toAdd(){
return "input";
}
@RequestMapping("add.do")
public String add(UserInfo userInfo){
userInfoService.add(userInfo);
return "ok";
}
}

页面信息在resources/templates下

input.html

<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">
<html>
<head>
<meta charset="UTF-8">
<title>增加信息的页面</title>
</head>
<body>
<form th:action="@{/user/add.do}" method="post">
姓名<input type="text" name="username"/><br/>
密码<input type="text" name="password"/><br/>
<input type="submit" value="增加">
</form>
</body>
</html>

application.properties 为数据库配置

Run App.main()
