将若依增强mybaties_plus版本

导入mybaties-plus依赖

进入 pom.xml (ruoyi) 标签中申明mybaties-plus版本

<mybatis-plus.version>3.4.3</mybatis-plus.version>

导入mybaties-plus 依赖

ruoyi(主工程模块)

   			<dependency>
                <groupId>com.baomidou</groupId>
                <artifactId>mybatis-plus-boot-starter</artifactId>

ruoyi(common模块)

分页插件需要去除mybaties依赖

        <!-- pagehelper 分页插件 -->
        <dependency>

            <artifactId>pagehelper-spring-boot-starter</artifactId>

                    <!-- 去除mybatis依赖 -->
                    <groupId>org.mybatis</groupId>
                    <artifactId>mybatis</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

其余依赖

  <!--常用工具类 -->
        <dependency>

            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>

ruoyi(admin)模块引入

 <!--freemarker-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-freemarker</artifactId>

ruoyi(freemework模块)
替换mybatie-plus依赖为mybatie-plus依赖

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;

     */
    public BlockAttackInnerInterceptor blockAttackInnerInterceptor()

mybatie-plus注入器 再freemework模块下进行配置

package com.ruoyi.framework.mybatisplus;

import java.util.Date;

/**

@Slf4j
@Component
public class CreateAndUpdateMetaObjectHandler implements MetaObjectHandler {

    @Override

        try {
            if (metaObject.hasGetter("createBy")) {
                this.setFieldValByName("createBy", getLoginUsername(), metaObject);

        } catch (Exception e) {
            throw new ServiceException("自动注入异常 => " + e.getMessage(), HttpStatus.HTTP_UNAUTHORIZED);
        }
        updateFill(metaObject);
    }

    @Override

        } catch (Exception e) {

        }
    }

    /**

            return null;
        }
        return loginUser.getUsername();
    }

}

修改德鲁伊连接池版本

ruoyi(主模块) propertie申明版本 这个版本与之前mp版本适配

 <druid.version>1.2.6</druid.version>

修改德鲁伊连接池properties文件配置1.2.6 api不同

文件路径 : com/ruoyi/framework/config/properties/DruidProperties.java

yml配置修改

模板修改

仅仅是集成了mybaties-plus还不够 ,还需要修改若依的代码生成模板进行适配
