SpringBoot 整合MyBatis-Plus
1. Maven依赖
<!-- mybatis-plus --> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.1.2</version> </dependency>
2. 注解
A. @MapperScan:指定要扫描的mapper类包的路径,加在启动类上;
3. application.yml配置文件
mybatis-plus: global-config: db-config: # 全局主键类型 id-type: auto configuration: # 是否开启下划线转驼峰规则映射 map-underscore-to-camel-case: true # mapper xml配置文件路径 mapper-locations: classpath*:mapper/*.xml # 直接使用类名,而非全限定类名 type-aliases-package: ${application.base-package}.entity
4. 插件分页配置类
package com.ruhuanxingyun.fastdfs.config; import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; /** * @description: MybatisPlus 配置类 * @author: ruphie * @date: Create in 2020/12/20 9:48 * @company: ruhuanxingyun */ @Configuration public class MybatisPlusConfig { @Bean public PaginationInterceptor paginationInterceptor() { return new PaginationInterceptor(); } }
