RuoYi-Vue 升级MybatisPlus

声明：基于RuoYi-Vue 3.8.6 版本升级

1. 引入依赖

模块名称：ruoyi-common
路径：pom.xml

        <!-- mybatis-plus 增强CRUD -->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.3.1</version>
        </dependency>

2. 配置替换

模块名称：ruoyi-framework
包路径：package com.ruoyi.framework.config.MyBatisConfig 注释
新增MybatisPlusConfig 配置

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();
    }
}

3. yml 调整

模块名称：ruoyi-admin
resources下面的application.yml中的MyBatis配置注释

新增下面MybatisPlus配置

# MyBatis配置
#mybatis:
#  # 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

# 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. 刷新maven依赖

使生效

5. 升级后测试

测试案例
   ----正常增删改查测试（例如用户模块）
   ----分页测试
