一、特别鸣谢若依开源，本文采用若依前后端分离3.8.5版本(非集群模式)进行改造
二、若依适配mybatis-plus
1、项目初始化
1.1、最低要求redis、mysql和nodejs
1.2、新建mysql库把sql文件夹下的quartz和ry打头的sql脚本初始化
1.3、在applelication·yml修改redis配置，application-druid·yml中修改mysql配置
1.4、修改前端项目ruoyi-ui文件目录下package·json里的scripts的dev配置，然后运行后台和前端（npm run dev）项目
"dev": "set NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service serve"2、开始改造
2.1、注释com.ruoyi.framework.config下的MyBatisConfig配置文件
2.2、在最外层的pom文件中申明mybatis-plus和分页的版本
<pagehelper.boot.version>1.4.6</pagehelper.boot.version>
<mybatis-plus.version>3.5.2</mybatis-plus.version>
<!--mybatis-plus-->
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>${mybatis-plus.version}</version>
</dependency>
<!-- pagehelper 分页插件 -->
<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper-spring-boot-starter</artifactId>
<version>${pagehelper.boot.version}</version>
</dependency>2.3、在comm模块的pom文件中直接引入依赖
<!--mybatis-plus-->
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
</dependency>
<!-- pagehelper 分页插件 -->
<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper-spring-boot-starter</artifactId>
<exclusions>
<exclusion>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
</exclusion>
</exclusions>
</dependency>
<!-- 小辣椒 -->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</dependency>2.4、修改applelication·yml中的mybatis-plus配置(直接将mybatis该成mybatis-plus,先不配置缓存等相关配置)
2.5、新增分页、乐观锁、自动填充字段配置(基础配置参考)，到此mybatis-plusd改造完成祝你启动成功
package com.ruoyi.framework.config;
import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;
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 com.ruoyi.common.utils.SecurityUtils;
import org.apache.ibatis.reflection.MetaObject;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.util.Date;
@Configuration
@ConditionalOnClass(value = {MyBatisPlusConfig.class})
public class MyBatisPlusConfig implements MetaObjectHandler {
//有多数据源 分页配置必须去DruidConfig里边配置
@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();
}
@Override
public void insertFill(MetaObject metaObject) {
Date now = new Date();
setFieldValByName("createTime", now, metaObject);
setFieldValByName("delFlag", "0", metaObject);
setFieldValByName("updateTime", now, metaObject);
setFieldValByName("createBy", SecurityUtils.getUsername(), metaObject);
setFieldValByName("updateBy", SecurityUtils.getUsername(), metaObject);
strictInsertFill(metaObject, "version", Integer.class, 1);
}
@Override
public void updateFill(MetaObject metaObject) {
Date now = new Date();
setFieldValByName("updateTime", now, metaObject);
setFieldValByName("updateBy", SecurityUtils.getUsername(), metaObject);
}
}三、代码自动生成模板改造
1、表实体改造，我主键id是雪花，所以在返前端的时候要用@JsonSerialize(using = ToStringSerializer.class)转字符串防前端精度丢失，主键自增长的可以自行更改主键生成属性
package ${packageName}.domain;
#foreach ($import in $importList)
import ${import};
#end
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableLogic;
import com.baomidou.mybatisplus.annotation.TableName;
import com.fasterxml.jackson.databind.annotation.JsonSerialize;
import com.fasterxml.jackson.databind.ser.std.ToStringSerializer;
import com.ruoyi.common.annotation.Excel;
import com.ruoyi.common.core.domain.BaseEntity;
import lombok.Data;
import lombok.EqualsAndHashCode;
#if($table.crud || $table.sub)
import com.ruoyi.common.core.domain.BaseEntity;
#elseif($table.tree)
import com.ruoyi.common.core.domain.TreeEntity;
#end
/**
* ${functionName}对象 ${tableName}
*
* @author ${author}
* @date ${datetime}
*/
#if($table.crud || $table.sub)
#set($Entity="BaseEntity")
#elseif($table.tree)
#set($Entity="TreeEntity")
#end
@Data
@EqualsAndHashCode(callSuper = true)
@TableName("${tableName}" )
public class ${ClassName} extends ${Entity}{
private static final long serialVersionUID=1L;
#foreach ($column in $columns)
#if(!$table.isSuperColumn($column.javaField))
/** $column.columnComment */
#if(${column.columnName}=="del_flag")
@TableLogic(value = "0", delval = "2" )
@TableField(value = "${column.columnName}" )
#elseif(${column.columnName}=="create_time")
@TableField(value = "${column.columnName}", fill = FieldFill.INSERT)
#elseif(${column.columnName}=="update_time")
@TableField(value = "${column.columnName}", fill = FieldFill.INSERT_UPDATE)
#elseif(${column.javaType} == "Long")
@JsonSerialize(using = ToStringSerializer.class)
@TableField(value = "${column.columnName}" )
#else
@TableField(value = "${column.columnName}" )
#end
#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
}2、mapper改造模板参考
package ${packageName}.mapper;
import org.apache.ibatis.annotations.Mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import java.util.List;
import ${packageName}.domain.${ClassName};
#if($table.sub)
import ${packageName}.domain.${subClassName};
#end
/**
* ${functionName}Mapper接口
*
* @author ${author}
* @date ${datetime}
*/
@Mapper
public interface ${ClassName}Mapper extends BaseMapper<${ClassName}> {
/**
* 查询${functionName}列表
*
* @param ${className} ${functionName}
* @return ${functionName}集合
*/
List<${ClassName}> select${ClassName}List(${ClassName} ${className});
/**
* 新增${functionName}
*
* @param ${className} ${functionName}
* @return 结果
*/
int insert${ClassName}(${ClassName} ${className});
/**
* 修改${functionName}
*
* @param ${className} ${functionName}
* @return 结果
*/
int update${ClassName}(${ClassName} ${className});
}3、server抽象层模板参考
package ${packageName}.service;
import java.util.List;
import com.baomidou.mybatisplus.extension.service.IService;
import ${packageName}.domain.${ClassName};
/**
* ${functionName}Service接口
*
* @author ${author}
* @date ${datetime}
*/
public interface I${ClassName}Service extends IService<${ClassName}>{
/**
* 查询${functionName}
*
* @param ${pkColumn.javaField} ${functionName}主键
* @return ${functionName}
*/
${ClassName} select${ClassName}By${pkColumn.capJavaField}(${pkColumn.javaType} ${pkColumn.javaField});
/**
* 查询${functionName}列表
*
* @param ${className} ${functionName}
* @return ${functionName}集合
*/
List<${ClassName}> select${ClassName}List(${ClassName} ${className});
/**
* 新增${functionName}
*
* @param ${className} ${functionName}
* @return 结果
*/
int insert${ClassName}(${ClassName} ${className});
/**
* 修改${functionName}
*
* @param ${className} ${functionName}
* @return 结果
*/
int update${ClassName}(${ClassName} ${className});
/**
* 批量删除${functionName}
*
* @param ${pkColumn.javaField}s 需要删除的${functionName}主键集合
* @return 结果
*/
int delete${ClassName}By${pkColumn.capJavaField}s(List<${pkColumn.javaType}> ${pkColumn.javaField}s);
/**
* 删除${functionName}信息
*
* @param ${pkColumn.javaField} ${functionName}主键
* @return 结果
*/
int delete${ClassName}By${pkColumn.capJavaField}(${pkColumn.javaType} ${pkColumn.javaField});
}4、实现层摸板参
package ${packageName}.service.impl;
import javax.annotation.Resource;
import java.util.List;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
#foreach ($column in $columns)
#if($column.javaField == 'createTime' || $column.javaField == 'updateTime')
import com.ruoyi.common.utils.DateUtils;
#break
#end
#end
import org.springframework.stereotype.Service;
#if($table.sub)
import java.util.ArrayList;
import com.ruoyi.common.utils.StringUtils;
import org.springframework.transaction.annotation.Transactional;
import ${packageName}.domain.${subClassName};
#end
import ${packageName}.mapper.${ClassName}Mapper;
import ${packageName}.domain.${ClassName};
import ${packageName}.service.I${ClassName}Service;
/**

*

*/
@Service
public class ${ClassName}ServiceImpl extends ServiceImpl<${ClassName}Mapper, ${ClassName}> implements I${ClassName}Service {
@Resource
private ${ClassName}Mapper ${className}Mapper;

*/
@Override
public ${ClassName} select${ClassName}By${pkColumn.capJavaField}(${pkColumn.javaType} ${pkColumn.javaField}) {
return ${className}Mapper.selectById(${pkColumn.javaField});
}
/**
* 查询${functionName}列表
*
* @param ${className} ${functionName}
* @return ${functionName}
*/
@Override
public List<${ClassName}> select${ClassName}List(${ClassName} ${className}) {
return ${className}Mapper.select${ClassName}List(${className});
}
/**
* 新增${functionName}
*
* @param ${className} ${functionName}
* @return 结果
*/
#if($table.sub)
@Transactional
#end
@Override
public int insert${ClassName}(${ClassName} ${className}) {
#foreach ($column in $columns)
#if($column.javaField == 'createTime')
${className}.setCreateTime(DateUtils.getNowDate());
#end
#end
#if($table.sub)
int rows = ${className}Mapper.insert${ClassName}(${className});
insert${subClassName}(${className});
return rows;
#else
return ${className}Mapper.insert${ClassName}(${className});
#end
}
/**

#end
#end
#if($table.sub)
${className}Mapper.delete${subClassName}By${subTableFkClassName}(${className}.get${pkColumn.capJavaField}());
insert${subClassName}(${className});
#end
return ${className}Mapper.update${ClassName}(${className});
}
/**
* 批量删除${functionName}
*
* @param ${pkColumn.javaField}s 需要删除的${functionName}主键
* @return 结果
*/
#if($table.sub)
@Transactional
#end
@Override
public int delete${ClassName}By${pkColumn.capJavaField}s(List<${pkColumn.javaType}> ${pkColumn.javaField}s) {
#if($table.sub)
${className}Mapper.delete${subClassName}By${subTableFkClassName}s(${pkColumn.javaField}s);
#end
return ${className}Mapper.deleteBatchIds(${pkColumn.javaField}s);
}

*/
public void insert${subClassName}(${ClassName} ${className}) {
List<${subClassName}> ${subclassName}List = ${className}.get${subClassName}List();
${pkColumn.javaType} ${pkColumn.javaField} = ${className}.get${pkColumn.capJavaField}();
if (StringUtils.isNotNull(${subclassName}List)) {
List<${subClassName}> list = new ArrayList<${subClassName}>();
for (${subClassName} ${subclassName} : ${subclassName}List){
${subclassName}.set${subTableFkClassName}(${pkColumn.javaField});
list.add(${subclassName});
}
if (list.size() > 0) {
${className}Mapper.batch${subClassName}(list);
}
}
}
#end
}5、接口层模板参考(反参这块对yapi这种文档生成平台不太友好，实际业务或后期再做统一模板封装)
package ${packageName}.controller;
