主要内容:升级成mybatis–plus,代码生成也是mybatis–plus版本
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。
代码: <!-- mybatis-plus 版本--> <mybatis-pluc.version>3.4.2</mybatis-pluc.version>
代码:
<!-- mybatis-plus 增强CRUD -->
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.4.2</version>
</dependency>
admin的包中的application.yml文件有mybatis–plus的提示,说明依赖弄好啦!
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.xml
global-config:
enable-sql-runner: true
db-config:
id-type: auto
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
/**
* 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();
}
}
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
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.
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!
3.在BaseEntity类中
