主要内容：升级成mybatis-plus，代码生成也是mybatis-plus版本

跟着我一步一步来，就可完成升级！

检查：启动程序，先保证若依能启动

第一步：添加依赖

        这里需要在两个地方添加，一个是最外面的父工程的pom.xml，一个是ruoyi-common的pom.xml。

        最外面的父工程的pom.xml：

        1.添加版本信息

代码：
<!--        mybatis-plus 版本--><mybatis-pluc.version>3.4.2</mybatis-pluc.version>

        2.添加mybatis-plus依赖

代码：

<!-- mybatis-plus 增强CRUD -->
<dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.4.2</version>
</dependency>

        ruoyi-common的pom.xml：

        1.直接继承父工程的依赖

第一步验证：

admin的包中的application.yml文件有mybatis-plus的提示，说明依赖弄好啦！

第二步：修改application.yml文件

        1.删除旧的mybatis配置

        2.写入新配置

        

代码：

# MyBatis Plus配置
mybatis-plus:# 搜索指定包别名   根据自己的项目来typeAliasesPackage: com.rchuing.sis.**.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.xmlglobal-config:enable-sql-runner: truedb-config:id-type: auto

第三步：重写mybatis配置文件

        1.在framework中，找到MybatisConfig文件，然后删除。

        

        2.在刚删除的文件夹下，新建一个MybatisPlus的java文件

        复制已下内容到java文件中：

/*** Mybatis Plus 配置** @author ruoyi*/
@EnableTransactionManagement(proxyTargetClass = true)
@Configuration
public class MybatisPlusConfig
{@Beanpublic 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mysqlpaginationInnerInterceptor.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();}
}

如图：

到这里Mybatis-plus就升级完成了。但代码生成里面还是以前mybatis的，这里也需要升级一下，方便代码生成。

第四步:把代码生成修改为mybatis-plus版本

1.在generator找到vm中的java文件夹

        

2.修改里面内容：这里直接上代码了，找到对应的直接复制粘贴就行。

到这里就升级完成。

下面进行测试：

1.

2.

3.如果看到mybatis的东西，说明升级成功！

注意： 

1.这里可能有些包的路径不对，把爆红的包删除，重新导入就可！

2.因为实际项目路径不同，这里可能需要手动修改！

3.在BaseEntity类中
