Spring Boot 服务端表单数据校验
实现添加用户功能
创建项目
修改pom文件

编写添加用户功能
创建实体
Users
package com.bjsxt.pojo;
public class Users {
private String name;
private String password;
private String 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 String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
@Override
public String toString() {
return "Users [name=" + name + ", password=" + password + ", age=" + age + "]";
}
}
创建Controller
package com.bjsxt.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.bjsxt.pojo.Users;
/**
* SpringBoot 表单数据校验
* @author john
*
*/
@Controller
public class UsersController {
@RequestMapping("/addUser")
public String showPage() {
return "add";
}
/**
* 完成用户添加
*/
@RequestMapping("/save")
public String saveUser(Users users) {
System.out.println(users);
return "OK";
}
}
编写页面
add.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>添加用户</title>
</head>
<body>
<form th:action="@{/save}" method="post">
用户姓名：<input type="text" name="name"><br/>
用户密码：<input type="password" name="password"><br/>
用户年龄：<input type="text" name="age"><br/>
<input type="submit" value="OK">
</form>
</body>
</html>
OK.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>操作成功</title>
</head>
<body>
OK！
</body>
</html>
启动类
package com.bjsxt;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
