主要内容升级mybatisplus代码生成也是mybatisplus版本

跟着我一步一步来,就可完成升级

检查启动程序,先保证若依启动

一步添加依赖

        这里需要两个地方添加一个是最外面的父工程pom.xml,一个是ruoyicommonpom.xml

        最外面的父工程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mybatisplus依赖

代码

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

        ruoyicommonpom.xml

        1.直接继承工程依赖

一步验证

admin包中application.yml文件mybatisplus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.写入配置

        

代码

# MyBatis Plus配置
mybatis-plus:
  # 搜索指定别名   根据自己项目typeAliasesPackage: com.rchuing.sis.**.domain 
  # 配置mapper扫描找到所有mapper.xml映射文件
  mapperLocations: classpath*:mapper/**/*Mapper.xml
  # 加载全局配置文件
  configLocation: classpath:mybatis/mybatis-config.xml
  global-config:
    enable-sql-runner: true
    db-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MybatisPlusjava文件

        复制已下内容java文件中:

/**
 * 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,就会终止操作 https://baomidou.com/guide/interceptor-block-attack.html
     */
    public BlockAttackInnerInterceptor blockAttackInnerInterceptor()
    {
        return new BlockAttackInnerInterceptor();
    }
}

如图

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:这里直接代码了,找到对应直接复制粘贴就行

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
