1.引入MyBatis-Plus依赖
在若依项目【我的若依框架版本号为：3.8.7】的总目录pom.xml文件中，引入MyBatis-Plus相关依赖：
代码如下，根据上图将两块代码放入对应位置：
<mybatis-plus.version>3.4.3</mybatis-plus.version>
<!-- mybatis-plus 增强CRUD --><dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>${mybatis-plus.version}</version></dependency> 2.在ruoyi-common下的pom.xml添加mybatis-plus依赖
代码如下：
<!-- mybatis-plus 增强CRUD --><dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId></dependency>
3.修改配置文件
ruoyi-admin下src\main\resources\application.yml,注释mybatis的配置，新增plus的配置，这段配置我是从若依官方拷贝过来的，如果跟你实际不一样就修改一下
# MyBatis Plus配置mybatis-plus: # 搜索指定包别名 typeAliasesPackage: com.ruoyi.**.domain # 配置mapper的扫描，找到所有的mapper.xml映射文件 mapperLocations: classpath*:mapper/**/*Mapper.xml # 加载全局的配置文件 configLocation: classpath:mybatis/mybatis-config.xml
4.重写mybatis配置文件
在framework中，找到MybatisConfig文件，然后删除，在刚删除的文件夹下，新建一个MybatisPlus的java文件，复制已下内容到java文件中：
package com.ruoyi.framework.config;import com.baomidou.mybatisplus.annotation.DbType;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.transaction.annotation.EnableTransactionManagement;import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;import com.baomidou.mybatisplus.extension.plugins.inner.OptimisticLockerInnerInterceptor;import com.baomidou.mybatisplus.extension.plugins.inner.BlockAttackInnerInterceptor;/** * Mybatis Plus 配置 * * @author ruoyi */@EnableTransactionManagement(proxyTargetClass = true)@Configurationpublic class MybatisPlusConfig{ @Bean public MybatisPlusInterceptor mybatisPlusInterceptor() { MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor(); // 分页插件 interceptor.addInnerInterceptor(paginationInnerInterceptor()); // 乐观锁插件 interceptor.addInnerInterceptor(optimisticLockerInnerInterceptor()); // 阻断插件 interceptor.addInnerInterceptor(blockAttackInnerInterceptor()); return interceptor; } /** * 分页插件，自动识别数据库类型 https://baomidou.com/guide/interceptor-pagination.html */ public PaginationInnerInterceptor paginationInnerInterceptor() { PaginationInnerInterceptor paginationInnerInterceptor = new PaginationInnerInterceptor(); // 设置数据库类型为mysql paginationInnerInterceptor.setDbType(DbType.MYSQL); // 设置最大单页限制数量，默认 500 条，-1 不受限制 paginationInnerInterceptor.setMaxLimit(-1L); return paginationInnerInterceptor; } /** * 乐观锁插件 https://baomidou.com/guide/interceptor-optimistic-locker.html */ public OptimisticLockerInnerInterceptor optimisticLockerInnerInterceptor() { return new OptimisticLockerInnerInterceptor(); } /** * 如果是对全表的删除或更新操作，就会终止该操作 https://baomidou.com/guide/interceptor-block-attack.html */ public BlockAttackInnerInterceptor blockAttackInnerInterceptor() { return new BlockAttackInnerInterceptor(); }}5.把代码生成修改为mybatis-plus版本
