Spring Boot整合MyBatis-Flex

news 2025/7/28 15:17:07

说明：MyBatis-Flex（官网地址：https://mybatis-flex.com/），是一款数据访问层框架，可实现项目中对数据库的访问，类比MyBatis-Plus。本文介绍，在Spring Boot项目整合MyBatis-Flex。

创建项目

首先，创建一个Spring boot项目，pom.xml文件内容如下

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.7.12</version><relativePath/></parent><groupId>com.hezy</groupId><artifactId>mybatis-flex-demo</artifactId><version>1.0-SNAPSHOT</version><name>Archetype - mybatis-flex-demo</name><url>http://maven.apache.org</url><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId><version>1.2.8</version></dependency><dependency><groupId>org.postgresql</groupId><artifactId>postgresql</artifactId><version>42.7.1</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-jdbc</artifactId></dependency></dependencies></project>

创建一个实体类对象，User，如下：

import lombok.Data;import java.io.Serializable;@Data
public class User implements Serializable {private static final long serialVersionUID = 1L;private Long id;private String username;private String password;
}

创建一个接口，如下：

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
public class UserController {@GetMapping("/hello")public String hello() {return "hello";}
}

application.yml，配置文件如下：

server:port: 8080spring:datasource:driver-class-name: org.postgresql.Driverurl: jdbc:postgresql://localhost:5432/demousername: postgrespassword: 123456

启动项目，测试，没得问题

在这里插入图片描述

整合MyBatis-Flex

引入下面这两个依赖；

	<dependency><groupId>com.mybatis-flex</groupId><artifactId>mybatis-flex-spring-boot-starter</artifactId><version>1.9.3</version></dependency><dependency><groupId>com.mybatis-flex</groupId><artifactId>mybatis-flex-processor</artifactId><version>1.9.3</version><scope>provided</scope></dependency>

在实体类上关联表，包括实体类对应的表名，以及对应的字段，像主键、别名（如果有）等；

import com.mybatisflex.annotation.Id;
import com.mybatisflex.annotation.Table;
import lombok.Data;import java.io.Serializable;@Data
@Table("tb_user")
public class User implements Serializable {private static final long serialVersionUID = 1L;@Idprivate Long id;private String username;private String password;
}

创建数据访问层对象，可继承MyBatis-Flex提供的接口，并指定泛型为当前操作的实体类对象

import com.hezy.pojo.User;
import com.mybatisflex.core.BaseMapper;
import org.apache.ibatis.annotations.Mapper;@Mapper
public interface UserMapper extends BaseMapper<User> {
}

创建一个接口，根据ID查询User，可直接调用MyBatis-Flex提供的相关API，如下：

    @Autowiredprivate UserMapper userMapper;@GetMapping("/getUser/{id}")public User getUserById(@PathVariable("id") Integer id) {return userMapper.selectOneById(id);}
