若依默认用的是mybatis，如何做增强呢，要整合mybatisplus。
在网上看了一圈，都没有特别完整的，按照若依官网的方法修改有不少问题，所以做如下总结。
有些内容自己也不太清楚，总之现在运行和开发没有问题，后续再补充。
参考文档：
若依官网：https://doc.ruoyi.vip/ruoyi-vue/document/cjjc.html#%E9%9B%86%E6%88%90mybatisplus%E5%AE%9E%E7%8E%B0mybatis%E5%A2%9E%E5%BC%BA
1、修改过程
1.1、引入依赖
hm-common/pom.xml
<!-- ruoyi-springboot3 / mybatis-plus 配置 -->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.5.16</version>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-spring-boot3-starter</artifactId>
<version>3.5.10</version>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-jsqlparser</artifactId>
<version>3.5.10</version>
</dependency>1.2、修改配置文件
hm-admin/src/main/resources/application.yml
原来的mybatis注释掉，新增plus的注释。
## MyBatis配置
#mybatis:
# # 搜索指定包别名
# typeAliasesPackage: com.hm.**.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
# MyBatis Plus配置
mybatis-plus:
# 搜索指定包别名
typeAliasesPackage: com.hm.**.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我看有些人把configLocation也注释了，我看了这个配置文件，用plus的原生功能也能替代，我这边就没注释，直接沿用。
1.3、新建mybatisplus配置类
hm-framework/src/main/java/com/hm/framework/config/MybatisPlusConfig.java
这边直接用的若依官网的配置类
记得把原来的MybatisConfig.java删了或者注释掉。
package com.hm.framework.config;
import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.BlockAttackInnerInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.OptimisticLockerInnerInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.EnableTransactionManagement;
/**
* Mybatis Plus 配置
*
* @author hm
*/
@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 <a href="https://baomidou.com/guide/interceptor-pagination.html">...</a>
*/
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 <a href="https://baomidou.com/guide/interceptor-optimistic-locker.html">...</a>
*/
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 <a href="https://baomidou.com/guide/interceptor-block-attack.html">...</a>
*/
public BlockAttackInnerInterceptor blockAttackInnerInterceptor()
{
return new BlockAttackInnerInterceptor();
}
}1.4、修改模板
要是还想用若依的代码生成，那就得改模板，要是自己写的话直接用就行了。
1.4.1、domain
这边主要是两个方面的修改，
一个是加上了lombok的注解，实现getset，无参和有参构造，toString方法。
二是加上@TableField(exist = false) ，让mybatisplus忽略一些字段，否则mybatis去数据库找字段找不到，就会报错。
package ${packageName}.domain;
#foreach ($import in $importList)
import ${import};
#end
import org.apache.commons.lang3.builder.ToStringBuilder;
import org.apache.commons.lang3.builder.ToStringStyle;
import com.hm.common.annotation.Excel;
#if($table.crud || $table.sub)
import com.hm.common.core.domain.BaseEntity;
#elseif($table.tree)
import com.hm.common.core.domain.TreeEntity;
#end
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableName;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;
/**
* ${functionName}对象 ${tableName}
*
* @author ${author}
* @date ${datetime}
*/
#if($table.crud || $table.sub)
#set($Entity="BaseEntity")
#elseif($table.tree)
#set($Entity="TreeEntity")
#end
@Data
@AllArgsConstructor
@NoArgsConstructor
@ToString
@TableName("${tableName}")
public class ${ClassName} extends ${Entity}
{
@TableField(exist = false)
private static final long serialVersionUID = 1L;
#foreach ($column in $columns)
#if(!$table.isSuperColumn($column.javaField))
/** $column.columnComment */
#if($column.list)
#set($parentheseIndex=$column.columnComment.indexOf("（"))
#if($parentheseIndex != -1)
#set($comment=$column.columnComment.substring(0, $parentheseIndex))
#else
#set($comment=$column.columnComment)
#end
#if($parentheseIndex != -1)
@Excel(name = "${comment}", readConverterExp = "$column.readConverterExp()")
#elseif($column.javaType == 'Date')
@JsonFormat(pattern = "yyyy-MM-dd")
@Excel(name = "${comment}", width = 30, dateFormat = "yyyy-MM-dd")
#else
@Excel(name = "${comment}")
#end
#end
private $column.javaType $column.javaField;
#end
#end
#if($table.sub)
/** $table.subTable.functionName信息 */
private List<${subClassName}> ${subclassName}List;
#end
}1.4.2、BaseEntity
由于我这边实体类继承了BaseEntity，所以BaseEntity里面，也有一些字段（searchValue，params）要加上注解让mybatisplus忽略，否则就会报错。
hm-common/src/main/java/com/hm/common/core/domain/BaseEntity.java
import java.io.Serializable;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;
import com.baomidou.mybatisplus.annotation.TableField;
import com.fasterxml.jackson.annotation.JsonFormat;
import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.annotation.JsonInclude;
/**
* Entity基类
*
* @author ruoyi
*/
public class BaseEntity implements Serializable
{
private static final long serialVersionUID = 1L;
/** 搜索值 */
@JsonIgnore
@TableField(exist = false)
private String searchValue;
/** 创建者 */
private String createBy;
/** 创建时间 */
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
private Date createTime;
/** 更新者 */
private String updateBy;
/** 更新时间 */
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
private Date updateTime;
/** 备注 */
private String remark;
/** 请求参数 */
@JsonInclude(JsonInclude.Include.NON_EMPTY)
@TableField(exist = false)
private Map<String, Object> params;
public String getSearchValue()
{
return searchValue;
}
public void setSearchValue(String searchValue)
{
this.searchValue = searchValue;
}
public String getCreateBy()
{
return createBy;
}
public void setCreateBy(String createBy)
{
this.createBy = createBy;
}
public Date getCreateTime()
{
return createTime;
}
public void setCreateTime(Date createTime)
{
this.createTime = createTime;
}
public String getUpdateBy()
{
return updateBy;
}
public void setUpdateBy(String updateBy)
{
this.updateBy = updateBy;
}
public Date getUpdateTime()
{
return updateTime;
}
public void setUpdateTime(Date updateTime)
{
this.updateTime = updateTime;
}
public String getRemark()
{
return remark;
}
public void setRemark(String remark)
{
this.remark = remark;
}
public Map<String, Object> getParams()
{
if (params == null)
{
params = new HashMap<>();
}
return params;
}
public void setParams(Map<String, Object> params)
{
this.params = params;
}
}1.4.3、mapper
hm-generator/src/main/resources/vm/java/mapper.java.vm
package ${packageName}.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import java.util.List;
import ${packageName}.domain.${ClassName};
#if($table.sub)

#end

}2、注意事项
2.1、mybatisplus和若依原始逻辑的冲突
由于我的实体类还是继承了BaseEntity，BaseEntity里面包含创建时间，更新时间，搜索条件等。
在调用mybatisplus的方法时候，例如save方法，创建时间和更新时间需要手动写入。
hm-manage/src/main/java/com/hm/manage/controller/StudentController.java
/**
* 新增学生信息
*/
@PreAuthorize("@ss.hasPermi('manage:student:add')")
@Log(title = "学生信息", businessType = BusinessType.INSERT)
@PostMapping
public AjaxResult add(@RequestBody Student student)
{
student.setCreateTime(new java.util.Date());
studentService.save(student);
//studentService.insertStudent(student);
return success();
}原始的方法里面Service接口里的insertStudent也是在impl里手动写入的。由于mybatisplus的save封装了，所以就得自己写了。
2.2、能否舍弃mapper的xml文件？
如果还在用若依的代码生成功能，那就不能舍弃，除非你想自己重写所有controller里的原生方法，我比较懒，就直接用原来的就完事了。
3、未解之谜
3.1、SysConfig要不要修改？
看到不少文章中写到要修改SysConfig相关，
MyBatisConfig.java 和 MybatisPlusConfig.java 改了SysConfig 上加了@TableName("sys_config")
对应的 interface SysConfigMapper extends BaseMapper<SysConfig>
interface ISysConfigService extends IService<SysConfig>
class SysConfigServiceImpl extends ServiceImpl<SysConfigMapper, SysConfig> implements ISysConfigService
我没有修改，也没发现什么问题。
