1、單體模塊在pom.xml ; 多模塊版本在ruoyi-common\pom.xml、模塊添加整合依賴

<!-- mybatis-plus 增強CRUD -->

<dependency>

	<groupId>com.baomidou</groupId>

	<artifactId>mybatis-plus-boot-starter</artifactId>

	<version>3.4.1</version>

</dependency>

2、單模塊在修改主題的application.yml ; 多模塊在ruoyi-admin文件application.yml，修改mybatis配置為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：原來的MyBatisConfig.java需要刪除掉

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.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();

        // 分頁插件

        interceptor.addInnerInterceptor(paginationInnerInterceptor());

        // 樂觀鎖插件

        interceptor.addInnerInterceptor(optimisticLockerInnerInterceptor());

        // 阻斷插件

        interceptor.addInnerInterceptor(blockAttackInnerInterceptor());

        return interceptor;

    }

    /**

     * 分頁插件，自動識別數據庫類型 https://baomidou.com/guide/interceptor-pagination.html

     */

    public PaginationInnerInterceptor paginationInnerInterceptor()

    {

        PaginationInnerInterceptor paginationInnerInterceptor = new PaginationInnerInterceptor();

        // 設置數據庫類型為mysql

        paginationInnerInterceptor.setDbType(DbType.MYSQL);

        // 設置最大單頁限制數量，默認 500 條，-1 不受限制

        paginationInnerInterceptor.setMaxLimit(-1L);

        return paginationInnerInterceptor;

    }

    /**

     * 樂觀鎖插件 https://baomidou.com/guide/interceptor-optimistic-locker.html

     */

    public OptimisticLockerInnerInterceptor optimisticLockerInnerInterceptor()

    {

        return new OptimisticLockerInnerInterceptor();

    }

    /**

     * 如果是對全表的刪除或更新操作，就會終止該操作 https://baomidou.com/guide/interceptor-block-attack.html

     */

    public BlockAttackInnerInterceptor blockAttackInnerInterceptor()

    {

        return new BlockAttackInnerInterceptor();

    }
