1、单体模块在pom.xml ; 多模块版本在ruoyi-common\pom.xml、模块添加整合依赖
<!-- mybatis-plus 增强CRUD -->
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.4.1</version>
</dependency>
2、单模块在修改主题的application.yml ; 多模块在ruoyi-admin文件application.yml，修改mybatis配置为mybatis-plus
# MyBatis Plus配置
mybatis-plus:
type-aliases-package: net.nachuan.doukuai.project.**.domain
mapper-locations: classpath*:mybatis/**/*Mapper.xml
config-location: classpath:mybatis/mybatis-config.xml
3、添加Mybatis Plus配置MybatisPlusConfig.java。 PS：原来的MyBatisConfig.java需要删除掉
package net.nachuan.doukuai.framework.config;
import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.BlockAttackInnerInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.OptimisticLockerInnerInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.EnableTransactionManagement;
/**

@EnableTransactionManagement(proxyTargetClass = true)
@Configuration
public 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();
}
/**

*/
public BlockAttackInnerInterceptor blockAttackInnerInterceptor()
{
return new BlockAttackInnerInterceptor();
}
}
