springboot+mybatis-plus代码生成器

首先mybatis-plus和代码生成器要导入依赖

       <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.5.1</version>
        </dependency>

        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity</artifactId>
            <version>1.7</version>
        </dependency>

 

加入MybatisPlusConfig

 

package com.xxxx.demo.config;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @ClassName MybatisPlusConfig
 * @Description
 * @Author Lishipu
 * @Date 2023/1/9 22:51
 * Version 1.0
 **/
@Configuration
@MapperScan("com.xxxx.demo.mapper")
public class MybatisPlusConfig{
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        return interceptor;
    }
}

模板

代码完整是这样的：

package com.xxxx.demo.utils;

import com.baomidou.mybatisplus.generator.FastAutoGenerator;
import com.baomidou.mybatisplus.generator.config.OutputFile;

import java.util.Collections;

/**
 * @ClassName CodeGenerator
 * @Description 代码生成器
 * @Author Lishipu
 * @Date 2023/1/10 23:05
 * Version 1.0
 **/
public class CodeGenerator {
    public static void main(String[] args) {
        generate();
    }
    private static void generate() {
        FastAutoGenerator.create("jdbc:mysql://localhost:3306/qing?useUnicode=true&useSSL=false&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai", "root", "123456")
                .globalConfig(builder -> {
                    builder.author("lishipu") // 设置作者
//                            .enableSwagger() // 开启 swagger 模式
                            .fileOverride() // 覆盖已生成文件
                            .outputDir("D:\\项目\\javaee+vue\\vue_01\\vue_springboot02\\src\\main\\java\\"); // 指定输出目录,注意是那个目录加个\\
                })
                .packageConfig(builder -> {
                    builder.parent("com.xxxx.demo") // 设置父包名
                            .moduleName(null) // 设置父包模块名
                            .pathInfo(Collections.singletonMap(OutputFile.mapperXml, "E:\\vue_01\\vue_springboot\\src\\main\\resources\\mapper\\")); // 设置mapperXml生成路径注意加个\\
                })
                .strategyConfig(builder -> {
                    builder.entityBuilder().enableLombok();
//                    builder.mapperBuilder().enableMapperAnnotation().build();
                    builder.controllerBuilder().enableHyphenStyle()  // 开启驼峰转连字符
                            .enableRestStyle();  // 开启生成@RestController 控制器
                    builder.addInclude("t_user") // 设置需要生成的表名
                            .addTablePrefix("t_", "sys_"); // 设置过滤表前缀
                })
//                .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
                .execute();

    }
}

第一

数据库名称和密码改一下，

 

 

 

第二

是这个地方，指定完路径之后要加个\\

 

 

 

第三

然后是这个地方,指定完包名

 

第四 

然后是这个地方：

 

 

 第五

就是修改要生成的表名

 

 最后

也是最主要的，就是新的代码生成器可以定制controller中的增删改查的代码

 

 

代码：

package ${package.Controller};


import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import org.springframework.web.bind.annotation.*;
import javax.annotation.Resource;
import java.util.List;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;

import ${package.Service}.${table.serviceName};
import ${package.Entity}.${entity};

#if(${restControllerStyle})
import org.springframework.web.bind.annotation.RestController;
#else
import org.springframework.stereotype.Controller;
#end
#if(${superControllerClassPackage})
import ${superControllerClassPackage};
#end

/**
 * <p>
 * $!{table.comment} 前端控制器
 * </p>
 *
 * @author ${author}
 * @since ${date}
 */
#if(${restControllerStyle})
@RestController
#else
@Controller
#end
@RequestMapping("#if(${package.ModuleName})/${package.ModuleName}#end/#if(${controllerMappingHyphenStyle})${controllerMappingHyphen}#else${table.entityPath}#end")
#if(${kotlin})
class ${table.controllerName}#if(${superControllerClass}) : ${superControllerClass}()#end

#else
#if(${superControllerClass})
public class ${table.controllerName} extends ${superControllerClass} {
#else
public class ${table.controllerName} {
#end

    @Resource
    private ${table.serviceName} ${table.entityPath}Service;

    // 新增或者更新
    @PostMapping
    public boolean save(@RequestBody ${entity} ${table.entityPath}) {
        return ${table.entityPath}Service.saveOrUpdate(${table.entityPath});
    }

    @DeleteMapping("/{id}")
    public Boolean delete(@PathVariable Integer id) {
        return ${table.entityPath}Service.removeById(id);
    }

    @PostMapping("/del/batch")
    public boolean deleteBatch(@RequestBody List<Integer> ids) {
        return ${table.entityPath}Service.removeByIds(ids);
    }

    @GetMapping
    public List<${entity}> findAll() {
        return ${table.entityPath}Service.list();
    }

    @GetMapping("/{id}")
    public ${entity} findOne(@PathVariable Integer id) {
        return ${table.entityPath}Service.getById(id);
    }

    @GetMapping("/page")
    public Page<${entity}> findPage(@RequestParam Integer pageNum,
                                    @RequestParam Integer pageSize) {
        QueryWrapper<${entity}> queryWrapper = new QueryWrapper<>();
        queryWrapper.orderByDesc("id");
        return ${table.entityPath}Service.page(new Page<>(pageNum, pageSize), queryWrapper);
    }
}

#end

这个代码的来源是：

 

 这些entity和mapper,service都可以定制
