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.version3.4.2/mybatis-pluc.version 2.添加mybatis-plus依赖 代码
!-- mybatis-plus 增强CRUD --
dependencygroupIdcom.baomidou/groupIdartifactIdmybatis-plus-boot-starter/artifactIdversion3.4.2/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
