1 创建maven项目
2 修改pom.xml文件
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

3 添加用户页面
3.1 addUser.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>添加用户</title>
</head>
<body>
<form th:action="@{/saveUser}" method="post">
用户姓名：<input type="text" name="name"/><br/><br/>
用户密码：<input type="password" name="password"/><br/><br/>
用户年龄：<input type="text" name="age"/><br/><br/>
<input type="submit" value="提交"/>
</form>
</body>
</html>
3.2 ok.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>操作提示页面</title>
</head>
<body>
操作成功
</body>
</html>
4 创建用户实体类Users.java
package com.bjsxt.pojo;
public class Users {
private String name;
private String password;
private Integer age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public Users(String name, String password, Integer age) {
super();
this.name = name;
this.password = password;
this.age = age;
}
public Users() {
super();
}
@Override
public String toString() {
return "Users [name=" + name + ", password=" + password + ", age=" + age + "]";
}
}
5 编写controller
@Controller
public class UsersController {
@RequestMapping("/addUser")
public String addUser() {
return "addUser";
}
@RequestMapping("/saveUser")
public String saveUser(Users users) {
return "ok";
}
}
6 编写启动类
@SpringBootApplication
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
7 启动测试
