此为基础配置,不包括其他高级配置,需要其他高级配置请查阅官方文档:[fluent mybatis特性总览 - Wiki - Gitee.com](https://gitee.com/fluent-mybatis/fluent-mybatis/wikis/fluent mybatis特性总览)
spring boot依赖

Fluent Mybatis和MySQL数据库依赖
<properties> <fluent-mybatis.version>1.9.9</fluent-mybatis.version> </properties> <dependencies> <!--mysql驱动--> <dependency> <groupId>com.mysql</groupId> <artifactId>mysql-connector-j</artifactId> <scope>runtime</scope> </dependency> <!-- 引入fluent-mybatis 运行依赖包, scope为compile --> <dependency> <groupId>com.github.atool</groupId> <artifactId>fluent-mybatis</artifactId> <version>${fluent-mybatis.version}</version> <exclusions> <exclusion> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> </exclusion> <exclusion> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> </exclusion> </exclusions> </dependency> <!-- 引入fluent-mybatis-processor, scope设置为provider 编译需要,运行时不需要 --> <dependency> <groupId>com.github.atool</groupId> <artifactId>fluent-mybatis-processor</artifactId> <scope>provided</scope> <version>${fluent-mybatis.version}</version> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>3.0.0</version> </dependency> </dependencies>
import cn.org.atool.fluent.mybatis.spring.MapperFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class MybatisConfig {
@Bean
public MapperFactory mapperFactory() {
return new MapperFactory();
}
}
在启动类添加mapper路径,注意Fluent的Mapper是不需要手动编写的,直接编译生成即可,在 target 目录下可以看到生成出来的文件。
@MapperScan("com.example.fluent.mapper")
创建 test
测试库,并创建 person
表。
CREATE TABLE `person` (
`id` int NOT NULL AUTO_INCREMENT,
`first_name` varchar(255) NOT NULL,
`last_name` varchar(255) NOT NULL,
`email` varchar(255) NOT NULL,
`age` int NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=10000001 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;
INSERT INTO `test`.`person` (`id`, `first_name`, `last_name`, `email`, `age`) VALUES (1, 'First0000001', 'Last0000001', 'email0000001@example.com', 92);
INSERT INTO `test`.`person` (`id`, `first_name`, `last_name`, `email`, `age`) VALUES (2, 'First0000002', 'Last0000002', 'email0000002@example.com', 33);
INSERT INTO `test`.`person` (`id`, `first_name`, `last_name`, `email`, `age`) VALUES (3, 'First0000003', 'Last0000003', 'email0000003@example.com', 19);
import cn.org.atool.fluent.mybatis.annotation.FluentMybatis; import cn.org.atool.fluent.mybatis.annotation.TableId; import cn.org.atool.fluent.mybatis.base.IEntity; import lombok.Data; @FluentMybatis(table = "person") @Data public class Person implements IEntity { @TableId //主键,不指定默认主键自增 private Long id; private String firstName; private String lastName; private String email; private int age; }
@RestController
public class PersonController {
@Resource
private PersonMapper personMapper;
@GetMapping("/data")
public Object getData() {
Person person = personMapper.findById(1); //查询ID为1的数据
return person;
}
}
server:
port: 8002 //指定8002端口运行
spring:
datasource:
type: com.zaxxer.hikari.HikariDataSource
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://192.168.2.6:3306/test?useSSL=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true
username: root
password: root
使用postman请求 http://localhost:8002/data 接口,测试是否可以拿到 id 为1的数据
可以看到结果是可以拿到的,整合完成。
这个例子是很简单的,很多参数都没有配置,比如下划线转驼峰之类的,有需要的可以去官方文档查询相关配置,这篇文章里就不赘述了。
