Mybatis-Plus是在Mybatis的基础上进行扩展,只做增强不做改变,可以兼容Mybatis原生的特性。同时支持通用CRUD操作、多种主键策略、分页、性能分析、全局拦截等。极大帮助我们简化开发工作。
1、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、ruoyi-admin文件application.yml,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
3、添加Mybatis Plus配置MybatisPlusConfig.java。
PS:原来的MyBatisConfig.java需要删除掉
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;
/**

* @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();
}
}
