基于EasyCode定制Mybatisplus全自动单表实现：新增/批量新增/修改/批量删除/分页查询/ID查询
阅读原文时间：2023年07月08日阅读：3

基于EasyCode定制Mybatisplus全自动单表实现CRUD接口

  • 分页查询
  • ID查询
  • 新增
  • 批量新增
  • 修改
  • 批量删除

注意使用了MybatisPlus的自动填充功能，和insertBatchSomeColumn扩展批量插入功能,分页插件

自动填充

package com.gton.config.autofull;

import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;
import lombok.extern.slf4j.Slf4j;
import org.apache.ibatis.reflection.MetaObject;
import org.springframework.stereotype.Component;

import java.time.LocalDateTime;

/**
 * @description: Mybatis -plus  自动填充
 * @author: GuoTong
 * @createTime: 2021-10-05 18:12
 * @since JDK 1.8 OR 11
 **/
@Slf4j
@Component
public class MyMetaObjectHandler implements MetaObjectHandler {

    @Override
    public void insertFill(MetaObject metaObject) {
        log.info("start insert fill ....");
        // 或者
        this.strictInsertFill(metaObject, "createTime", LocalDateTime::now, LocalDateTime.class); // 起始版本 3.3.3(推荐)
        this.strictInsertFill(metaObject, "updateTime", LocalDateTime::now, LocalDateTime.class); // 起始版本 3.3.3(推荐)
    }

    @Override
    public void updateFill(MetaObject metaObject) {
        log.info("start update fill ....");
        this.strictUpdateFill(metaObject, "updateTime", LocalDateTime::now, LocalDateTime.class); // 起始版本 3.3.3(推荐)

    }
}

分页插件

    /**
     * Description:  新的分页插件
     *
     * @author: GuoTong
     */
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        // 向Mybatis过滤器链中添加分页拦截器
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        // 添加乐观锁插件
        interceptor.addInnerInterceptor(new OptimisticLockerInnerInterceptor());
        return interceptor;
    }

自定义扩展批量插入

package com.gton.handler;

import com.baomidou.mybatisplus.annotation.FieldFill;
import com.baomidou.mybatisplus.core.injector.AbstractMethod;
import com.baomidou.mybatisplus.core.injector.DefaultSqlInjector;
import com.baomidou.mybatisplus.core.metadata.TableInfo;
import com.baomidou.mybatisplus.extension.injector.methods.InsertBatchSomeColumn;

import java.util.List;

/**
 * @description: MyBatis-Plus提供的InsertBatchSomeColumn方法
 * @author: GuoTong
 * @createTime: 2022-12-06 16:24
 * @since JDK 1.8 OR 11
 **/
public class EasySqlInjector extends DefaultSqlInjector {

    @Override
    public List<AbstractMethod> getMethodList(Class<?> mapperClass, TableInfo tableInfo) {
        // 注意：此SQL注入器继承了DefaultSqlInjector(默认注入器)，调用了DefaultSqlInjector的getMethodList方法，保留了mybatis-plus的自带方法
        List<AbstractMethod> methodList = super.getMethodList(mapperClass, tableInfo);
        methodList.add(new InsertBatchSomeColumn(i -> i.getFieldFill() != FieldFill.UPDATE));
        return methodList;
    }

}

批量插入插件注入

    @Bean
    public EasySqlInjector sqlInjector() {
        return new EasySqlInjector();

Mapper模板

##引入mybatis支持
$!{mybatisSupport.vm}

##设置保存名称与保存位置
$!callback.setFileName($tool.append($!{tableInfo.name}, "Mapper.xml"))
$!callback.setSavePath($tool.append($modulePath, "/src/main/resources/mapper"))

##拿到主键
#if(!$tableInfo.pkColumn.isEmpty())
    #set($pk = $tableInfo.pkColumn.get(0))
#end

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="$!{tableInfo.savePackageName}.mapper.$!{tableInfo.name}Mapper">

    <resultMap type="$!{tableInfo.savePackageName}.entity.$!{tableInfo.name}" id="$!{tableInfo.name}Map">

        <result property="$!column.name" column="$!column.obj.name" jdbcType="$!column.ext.jdbcType"/>
#end

生成接口如下

如果你把我的方式拿过去使用，那么你肯定会报错，你还差通用请求和响应类
