SpringBoot整合Mybatis-flex

第 1 步：创建数据库表

CREATE TABLE IF NOT EXISTS `tb_account`
(
    `id`        INTEGER PRIMARY KEY auto_increment,
    `user_name` VARCHAR(100),
    `age`       INTEGER,
    `birthday`  DATETIME
);

INSERT INTO tb_account(id, user_name, age, birthday)
VALUES (1, '张三', 18, '2020-01-11'),
       (2, '李四', 19, '2021-03-21');

第 2 步：创建 Spring Boot 项目，并添加 Maven 依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>com.mybatis-flex</groupId>
    <artifactId>mybatis-flex-spring-boot-starter</artifactId>
    <version>1.8.1</version>
</dependency>
<dependency>
    <groupId>com.mybatis-flex</groupId>
    <artifactId>mybatis-flex-processor</artifactId>
    <version>1.8.1</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.2.6</version>
</dependency>
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

第 3 步：对 Spring Boot 项目进行配置

配置文件配置(application.yml)

# DataSource Config
spring:
  datasource:
    url: jdbc:mysql://localhost:3306/flex_test
    username: root
    password: 12345678

在 SpringBootApplication启动类中添加 @MapperScan 注解

@MapperScan("com.mybatisflex.test.mapper")

第 4 步：编写实体类Account和 Mapper 接口

实体类Account：

@Data
@Table("tb_account")
public class Account {

    @Id(keyType = KeyType.Auto)
    private Long id;
    private String userName;
    private Integer age;
    private Date birthday;

}

接口类：

package com.mybatisflex.mapper;

import com.mybatisflex.core.BaseMapper;
import com.mybatisflex.enity.Account;

public interface AccountMapper extends BaseMapper<Account> {
}

第 5 步：编写测试MybatisFlexApplicationTests类

@SpringBootTest
class MybatisFlexApplicationTests {

    @Autowired
    private AccountMapper accountMapper;

    @Test
    void contextLoads() {
        //查看全部
//        List<Account> accounts = accountMapper.selectAll();
//        accounts.forEach(System.out::println);
        //精确查询
        QueryWrapper queryWrapper = QueryWrapper.create()
                .select()
                .where(ACCOUNT.AGE.eq(18));
        Account account = accountMapper.selectOneByQuery(queryWrapper);
        System.out.println(account);
    }

}

进行全部查询和精确查询测试，控制台输出结果
