因为使用SpringBoot 3.2.1 出了一些问题,下面改成2.5.14
4.0.0 org.springframework.boot spring-boot-starter-parent 2.5.14 org.dam increment-backup-serve 0.0.1-SNAPSHOT increment-backup-serve increment-backup-serve 17 org.springframework.boot spring-boot-starter org.springframework.boot spring-boot-starter-web org.projectlombok lombok true org.xerial sqlite-jdbc 3.21.0.1 com.baomidou mybatis-plus-boot-starter 3.4.3.1 org.springframework.boot spring-boot-starter-test test org.springframework.boot spring-boot-maven-plugin
使用Macbook pro运行项目,会报如下错误
Caused by: java.lang.Exception: No native library is found for os.name=Mac and os.arch=aarch64. path=/org/sqlite/native/Mac/aarch64
解决方案,修改版本
org.xerial sqlite-jdbc 3.32.3.3
我的开发机是mac系统,自动了sqlite3,如果你们没有的话,要去安装,可以参考官方文档的快速开始:https://www.sqlite.org/quickstart.html
mac@MacdeMac-Pro ~ % sqlite3 SQLite version 3.39.4 2022-09-07 20:51:41 Enter ".help" for usage hints. Connected to a transient in-memory database. Use ".open FILENAME" to reopen on a persistent database.
从一个目录进入终端,创建数据库
mac@MacdeMac-Pro sql % sqlite3 increment-backup.db; SQLite version 3.39.4 2022-09-07 20:51:41 Enter ".help" for usage hints.
查看数据库是否创建成功
sqlite> .databases main: /Volumes/MacSpan/Projects/increment-backup/sql/DatabaseName.db r/w
创建成功,出现如下文件

创建数据表
sqlite> create table user ...> ( ...> id INTEGER not null primary key autoincrement, ...> name varchar(20) ...> );
查看数据表
sqlite> .tables user


连接成功



连接成功

如果没有安装如下插件的话,先安装一下




生成成功

创建如下项目结构,并粘贴所生成的代码过去

注意,mapper.xml的实体类引用要和你项目的一致

因为只是非常简单的案例,这里先不使用service包下的代码
package org.dam.entity;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;
import java.io.Serializable;
/**
*
* @TableName user
*/
@TableName(value ="user")
@Data
public class User implements Serializable {
/**
*
*/
@TableId(type = IdType.AUTO)
private Integer id;
/**
*
*/
private String name;
@TableField(exist = false)
private static final long serialVersionUID = 1L;
@Override
public boolean equals(Object that) {
if (this == that) {
return true;
}
if (that == null) {
return false;
}
if (getClass() != that.getClass()) {
return false;
}
User other = (User) that;
return (this.getId() == null ? other.getId() == null : this.getId().equals(other.getId()))
&& (this.getName() == null ? other.getName() == null : this.getName().equals(other.getName()));
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((getId() == null) ? 0 : getId().hashCode());
result = prime * result + ((getName() == null) ? 0 : getName().hashCode());
return result;
}
@Override
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append(getClass().getSimpleName());
sb.append(" [");
sb.append("Hash = ").append(hashCode());
sb.append(", id=").append(id);
sb.append(", name=").append(name);
sb.append(", serialVersionUID=").append(serialVersionUID);
sb.append("]");
return sb.toString();
}
}
package org.dam.mapper; import com.baomidou.mybatisplus.core.mapper.BaseMapper; import org.dam.entity.User; /** * @author mac * @description 针对表【user】的数据库操作Mapper * @createDate 2024-01-18 21:12:12 * @Entity generator.entity.User */ public interface UserMapper extends BaseMapper{ }
id,name
package org.dam.controller;
import org.dam.entity.User;
import org.dam.mapper.UserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
/**
* @Author dam
* @create 2024/1/18 20:37
*/
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
UserMapper userMapper;
/**
* 增添数据
*/
@GetMapping("/insert")
public Object insert(String name) {
User user = new User();
user.setName(name);
return userMapper.insert(user);
}
/**
* 查询数据
*/
@GetMapping("/show")
public Object show() {
return userMapper.selectList(null);
}
/**
* 删除数据
*/
@DeleteMapping("/delete")
public Object delete(Integer id) {
return userMapper.deleteById(id);
}
/**
* 修改数据
*/
@GetMapping("/update")
public Object update(Integer id, String name) {
User user = new User();
user.setId(id);
user.setName(name);
return userMapper.updateById(user);
}
}
注意url要对应sqlite数据库

# Tomcat

package org.dam;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;

@SpringBootApplication
@MapperScan("org.dam.mapper")
public class IncrementBackupServeApplication {
public static void main(String[] args) {
SpringApplication.run(IncrementBackupServeApplication.class, args);
}
}
我这边使用接口测试工具Apifox来进行测试,使用Postman等其他工具也是可以的,不过我强烈推荐Apifox,感觉非常好用
