ruoyi：集成mybatisplus实现mybatis增强

一、添加整合依赖

在ruoyi-common\pom.xml模块添加

1.ruoyi-springboot2：增加依赖

用mybatis-plus-boot-starter依赖

<!-- ruoyi-springboot2 / mybatis-plus 配置 -->
<dependency>
	<groupId>com.baomidou</groupId>
	<artifactId>mybatis-plus-boot-starter</artifactId>
</dependency>

父pom添加依赖管理

<properties>
        <mybatis.version>3.5.1</mybatis.version>
</properties>

<!-- ruoyi-springboot2 / mybatis-plus 配置 -->
<dependency>
	<groupId>com.baomidou</groupId>
	<artifactId>mybatis-plus-boot-starter</artifactId>
	<version>${mybatis-plus.version}</version>
</dependency>

2.ruoyi-springboot3：增加依赖

用mybatis-plus-spring-boot3-starter依赖

<!-- ruoyi-springboot3 / mybatis-plus 配置 -->
<dependency>
	<groupId>org.mybatis</groupId>
	<artifactId>mybatis</artifactId>
</dependency>

<dependency>
	<groupId>com.baomidou</groupId>
	<artifactId>mybatis-plus-spring-boot3-starter</artifactId>
</dependency>

<dependency>
	<groupId>com.baomidou</groupId>
	<artifactId>mybatis-plus-jsqlparser</artifactId>
</dependency>

父pom添加依赖管理

<properties>
        <mybatis-plus.version>3.5.10</mybatis-plus.version>
        <mybatis.version>3.5.16</mybatis.version>
</properties>

            <!-- ruoyi-springboot3 / mybatis-plus 配置 -->
            <dependency>
                <groupId>org.mybatis</groupId>
                <artifactId>mybatis</artifactId>
                <version>${mybatis.version}</version>
            </dependency>

            <dependency>
                <groupId>com.baomidou</groupId>
                <artifactId>mybatis-plus-spring-boot3-starter</artifactId>
                <version>${mybatis-plus.version}</version>
            </dependency>

            <dependency>
                <groupId>com.baomidou</groupId>
                <artifactId>mybatis-plus-jsqlparser</artifactId>
                <version>${mybatis-plus.version}</version>
            </dependency>

二、修改application.yml文件

修改mybatis配置为mybatis-plus

# 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

三、删除MyBatisConfig.java文件

ruoyi-framework -> config -> MyBatisConfig.java文件，删除

四、新增MybatisPlusConfig.java文件

ruoyi-framework -> config -> MybatisPlusConfig.java文件，新增

package com.ruoyi.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;

/**
 * Mybatis Plus 配置
 * 
 * @author ruoyi
 */
@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();
    }

    /**
     * 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();
    }
}

四、启动测试

到此步集成完成。
