3. 启动类 Starter.java
package com.java.springboot; import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer; /**
* 启动类
*
* @author Logan
* @version 1.0.0
*
*/
@SpringBootApplication
public class Starter extends SpringBootServletInitializer { public static void main(String[] args) {
SpringApplication.run(Starter.class, args);
} @Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Starter.class);
} }
4. User.java
package com.java.springboot.pojo;
public class User {
private String id;
private String username;
private String password;

userMapper.addUser(user);
} else {
userMapper.updateUser(user);
}
} @Override
@Transactional
public void deleteUser(User user) {
userMapper.deleteUser(user);
} }
9、UserController.java

*/
@Configuration
@MapperScan({ "com.java.springboot.mapper" })
public class ApplicationConfig { }

18. 创建数据库
DROP DATABASE IF EXISTS springboot;
CREATE DATABASE springboot;
USE springboot;
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`id` varchar(32) NOT NULL,
`username` varchar(32) NOT NULL,
`password` varchar(32) NOT NULL,
`age` int(3) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8; ;
注意：
jquery-3.3.1.min.js 请自行下载，配置到Main.jsp文件中
https://code.jquery.com/jquery-3.3.1.min.js
http://code.jquery.com/jquery-3.3.1.min.js
打开网址，Ctrl + S 保存文件
配置完成！
