项目实训智能创新引导工具(1)

一、建立后端SpringBoot项目

File-->New-->Project 选择Spring Initializr

依赖选择Lombok&＃xff0c;Spring Web,MyBatis Framework,MySQL Driver

二、后端项目配置与调试

在maven的配置文件pom.xml中配置阿里云镜像仓库&＃xff0c;加速下载

nexus-aliyunnexus-aliyunhttp://maven.aliyun.com/nexus/content/groups/public/truefalse
publicaliyun nexushttp://maven.aliyun.com/nexus/content/groups/public/truefalse


 在navicat中操作建立数据库。

编辑配置文件application.properties&＃xff0c;连接数据库

server.port&＃61;9090spring.datasource.driver-class-name&＃61;com.mysql.cj.jdbc.Driver
spring.datasource.url&＃61;jdbc:mysql://localhost:3306/creative_tool?serverTimezone&＃61;GMT%2b8
spring.datasource.username&＃61;root
spring.datasource.password&＃61;123456

 在启动类中&＃xff0c;编写接口进行测试

&＃64;RestController
&＃64;SpringBootApplication
public class SpringbootApplication {public static void main(String[] args) {SpringApplication.run(SpringbootApplication.class, args);}&＃64;GetMapping("/")public String index() {return "ok";}

 新建User实体类

import lombok.Data;&＃64;Data
public class User {private Integer id;private String username;private String password;private String nickname;private String email;private String phone;private String sex;private String profilepic;
}

 新建UserMapper&＃xff0c;通过注解编写sql进行测试

import com.example.springboot.entity.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;import java.util.List;&＃64;Mapper
public interface UserMapper {&＃64;Select("SELECT * from user")List findAll();}

新建UserController&＃xff0c;编写接口&＃xff0c;返回所有用户&＃xff0c;进行测试

import com.example.springboot.entity.User;
import com.example.springboot.mapper.UserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;import java.util.List;&＃64;RestController
public class UserController {&＃64;Autowiredprivate UserMapper userMapper;&＃64;GetMapping("/")public List index() {List all &＃61; userMapper.findAll();return all;}
}

 测试结果&＃xff1a;
