没有搭建ssm经验的同学请移步SSM后端框架搭建（有图有真相）_ssm编写后台接口-CSDN博客

环境搭建

1.创建项目

2.配置pom.xml文件

<properties>
    <maven.compiler.source>18</maven.compiler.source>
    <maven.compiler.target>18</maven.compiler.target>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
  <!--导入父工程-->
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>3.1.0</version>
</parent>

<dependencies>
    <!--springmvc-->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>
<build>
    <plugins>
        <plugin>
            <!--将文件打包默认jar-->
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

3.配置启动类，类名可随意

4.建立controller层

5.运行启动类

整合mybatis

1.添加pom文件

<!--MySQL驱动-->
<dependency>
    <groupId>com.mysql</groupId>
    <artifactId>mysql-connector-j</artifactId>
</dependency>
<!--springboot整合mybatis-->
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>3.0.3</version>
</dependency>
<!--lombok-->
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.30</version>
</dependency>

2.设置配置文件application.yml

文件名不可更改文件缩进不可更改

3.新建数据库表

DROP TABLE IF EXISTS `user`;

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `uid` varchar(8) DEFAULT NULL,
  `name` varchar(255) DEFAULT NULL,
  `age` int(11) DEFAULT NULL,
  `sex` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=25 DEFAULT CHARSET=utf8;

/*Data for the table `user` */

insert  into `user`(`id`,`uid`,`name`,`age`,`sex`) values 

(10,'20240909','张三丰',9999,'男'),

(11,'20240907','张无忌',111,'男'),

(12,'12010909','郭靖',11,'男'),
