SpringBoot+MyBatisPlus+Vue 前后端分离项目快速搭建过程(后端)

数据库准备

data_test.sql：

后端搭建

1、快速创建个SpringBoot项目

第一步：Spring Initializr

第二步：Spring Initializr Project Settings

第三步：添加个Lombok工具

第四步：Finish

初始化的样子：

2、引入依赖

此处贴上整个pom.xml，部分依赖可能对于简单需求而言是多余的，可以自行舍弃。

pom.xml代码：

3、编写代码快速生成代码

因为此代码为辅助代码，放在test包下即可，相关的数据库信息以及包信息需要和你们自己的保持一致，自行修改，如何包命名和我一致，只需要修改数据库相关信息即可。

CodeGenerator：

package com.keafmd.mp;
import com.baomidou.mybatisplus.core.exceptions.MybatisPlusException;
import com.baomidou.mybatisplus.core.toolkit.StringPool;
import com.baomidou.mybatisplus.core.toolkit.StringUtils;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.InjectionConfig;
import com.baomidou.mybatisplus.generator.config.*;
import com.baomidou.mybatisplus.generator.config.po.TableInfo;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

 */
public class CodeGenerator {

    /**
     * 

     * 读取控制台内容
     * 
     */
    public static String scanner(String tip) {
        Scanner scanner = new Scanner(System.in);
        StringBuilder help = new StringBuilder();
        help.append("请输入" + tip + "：");
        System.out.println(help.toString());
        if (scanner.hasNext()) {
            String ipt = scanner.next();
            if (StringUtils.isNotBlank(ipt)) {
                return ipt;
            }
        }
        throw new MybatisPlusException("请输入正确的" + tip + "！");
    }

    public static void main(String[] args) {
        // 代码生成器
        AutoGenerator mpg = new AutoGenerator();

        // 全局配置
        GlobalConfig gc = new GlobalConfig();
        String projectPath = System.getProperty("user.dir");
//        System.out.println("projectPath = " + projectPath);
        gc.setOutputDir(projectPath + "/src/main/java");
//        gc.setOutputDir("D:\\test");
        gc.setAuthor("关注公众号：牛哄哄的柯南");
        gc.setOpen(false);
        // gc.setSwagger2(true); 实体属性 Swagger2 注解
        gc.setServiceName("%sService");
        mpg.setGlobalConfig(gc);

        // 数据源配置
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://127.0.0.1:3306/data_test?useUnicode=true&useSSL=false&characterEncoding=utf8&serverTimezone=UTC");
        // dsc.setSchemaName("public");
        dsc.setDriverName("com.mysql.jdbc.Driver");
        dsc.setUsername("root");
        dsc.setPassword("18044229");
        mpg.setDataSource(dsc);

        // 包配置
        PackageConfig pc = new PackageConfig();
        pc.setModuleName(null);
        pc.setParent("com.keafmd");
        mpg.setPackageInfo(pc);

        // 自定义配置
        InjectionConfig cfg = new InjectionConfig() {
            @Override
            public void initMap() {
                // to do nothing
            }
        };

        // 如果模板引擎是 freemarker
        String templatePath = "/templates/mapper.xml.ftl";
        // 如果模板引擎是 velocity
        // String templatePath = "/templates/mapper.xml.vm";

        // 自定义输出配置
        List focList = new ArrayList<>();
        // 自定义配置会被优先输出
        focList.add(new FileOutConfig(templatePath) {
            @Override
            public String outputFile(TableInfo tableInfo) {
                // 自定义输出文件名 ， 如果你 Entity 设置了前后缀、此处注意 xml 的名称会跟着发生变化！！
                return projectPath + "/src/main/resources/com/keafmd/mapper/" + tableInfo.getEntityName() + "Mapper" + StringPool.DOT_XML;
            }
        });

        cfg.setFileOutConfigList(focList);
        mpg.setCfg(cfg);

        // 配置模板
        TemplateConfig templateConfig = new TemplateConfig();

        templateConfig.setXml(null);
        mpg.setTemplate(templateConfig);

        // 策略配置
        StrategyConfig strategy = new StrategyConfig();
        strategy.setNaming(NamingStrategy.underline_to_camel);
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);
        strategy.setEntityLombokModel(true);
        strategy.setRestControllerStyle(true);
        strategy.setInclude(scanner("表名，多个英文逗号分割").split(","));
        strategy.setControllerMappingHyphenStyle(true);
        strategy.setTablePrefix("m_");
        mpg.setStrategy(strategy);
        mpg.setTemplateEngine(new FreemarkerTemplateEngine());
        mpg.execute();
    }
}

4、运行代码生成器生成代码

在控制台输入user（表名）

红框内为自动生成的代码：

5、编写application.properties

个人习惯把application.properties改为application.yml，修改端口为80

server:
  port: 80

spring:
  datasource:
    url: jdbc:mysql://127.0.0.1/data_test?useSSL=false&&characterEncoding=UTF-8
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: 18044229

  jackson:
    date-format: yyyy-MM-dd HH:mm:ss
    time-zone: GMT+8
  mvc:
    throw-exception-if-no-handler-found: true
  web:
    resources:
      add-mappings: false

6、在启动类上添加@MapperScan

SpringbootServerApplication：

package com.keafmd;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@MapperScan("com.keafmd.mapper")
public class SpringbootServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootServerApplication.class, args);
    }

}

7、编写测试代码测试数据库是否连接正确

1、在 UserMapper代码页大括号内，按下Alt+Insert，选择Test

2、Ok

3、自动生成了测试类

4、编写测试代码

UserMapperTest ：

package com.keafmd.mapper;

import com.keafmd.SpringbootServerApplication;
import com.keafmd.entity.User;
import com.keafmd.service.UserService;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

import javax.annotation.Resource;

import java.util.List;

import static org.junit.jupiter.api.Assertions.*;

@SpringBootTest(classes = SpringbootServerApplication.class)
class UserMapperTest {

    @Resource
    UserService userService;

    @Test
    public void test1(){
        List userList = userService.list();
        for (User user : userList) {
            System.out.println(user);
        }

    }



}

5、测试结果

至此，后端和数据库连接没问题。

8、编写后端的工具类代码（封装结果集、日期处理、解决跨域请求）

1、CommonResult

package com.keafmd.common;

import lombok.Getter;

/**
 * Keafmd
 *
 * @ClassName: CommonResult
 * @Description: 封装结果集
 * @author: 牛哄哄的柯南
 * @Date: 2021-04-29 18:11
 * @Blog: https://keafmd.blog.csdn.net/
 */

@Getter
public class CommonResult  {
    private Integer code;
    private String message;
    private Object obj;

    private CommonResult(Integer code, String message, Object obj) {
        this.code = code;
        this.message = message;
        this.obj = obj;
    }

    public static CommonResult nohandler() {
        return new CommonResult(ResultCode.NOHANDLER.getCode(), ResultCode.NOHANDLER.getMessage(),null);
    }
    public static CommonResult success(Object data) {
        return new CommonResult(ResultCode.SUCCESS.getCode(), ResultCode.SUCCESS.getMessage(),data);
    }
    public static CommonResult failed() {
        return new CommonResult(ResultCode.FAILED.getCode(), ResultCode.FAILED.getMessage(),null);
    }
    public static CommonResult failed(String message) {
        return new CommonResult(ResultCode.FAILED.getCode(),message,null);
    }
    public static CommonResult notoken() {
        return new CommonResult(ResultCode.NOTOKEN.getCode(), ResultCode.NOTOKEN.getMessage(),null);
    }
    public static CommonResult nopremiss() {
        return new CommonResult(ResultCode.NOPERMISS.getCode(), ResultCode.NOPERMISS.getMessage(),null);
    }
}

2、DateConverter

package com.keafmd.common;

import org.springframework.context.annotation.Configuration;
import org.springframework.core.convert.converter.Converter;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import java.util.regex.Pattern;

/**
 * Keafmd
 *
 * @ClassName: DateConverter
 * @Description: 日期处理
 * @author: 牛哄哄的柯南
 * @Date: 2021-04-29 18:11
 * @Blog: https://keafmd.blog.csdn.net/
 */

@Configuration
public class DateConverter implements Converter {

    public DateConverter() {
//        System.out.println("初始化........");
    }

    static List sdfs = new ArrayList();

    static {
        sdfs.add(new SimpleDateFormat("yyyy/MM/dd HH:mm:ss"));
        sdfs.add(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));
        sdfs.add(new SimpleDateFormat("yyyy-MM-dd"));
        sdfs.add(new SimpleDateFormat("yyyy/MM/dd"));

    }

    @Override
    public Date convert(String s) {
        SimpleDateFormat sdf = null;
        if (Pattern.matches("^\\d{4}-\\d{2}-\\d{2} \\d{2}:\\d{2}:\\d{2}$", s)) {
            sdf = sdfs.get(1);
        }
        else if (Pattern.matches("^\\d{4}/\\d{2}/\\d{2} \\d{2}:\\d{2}:\\d{2}$", s)){
            sdf = sdfs.get(0);
        }
        else if (Pattern.matches("^\\d{4}/\\d{2}/\\d{2}$", s)){
            sdf = sdfs.get(3);
        }
        else if (Pattern.matches("^\\d{4}-\\d{2}/-\\d{2}}$", s)){
            sdf = sdfs.get(2);
        }

        Date date = null;
        try {
            date = sdf.parse(s);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return date;

    }
}

3、LocalDateTimeConverter

package com.keafmd.common;

import org.springframework.core.convert.converter.Converter;
import org.springframework.stereotype.Component;

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

/**
 * Keafmd
 *
 * @ClassName: LocalDateTimeConverter
 * @Description: 日期处理
 * @author: 牛哄哄的柯南
 * @Date: 2021-04-29 18:11
 * @Blog: https://keafmd.blog.csdn.net/
 */

@Component
public class LocalDateTimeConverter implements Converter {
    //2021-04-29%2001:02:03
    @Override
    public LocalDateTime convert(String s) {
        return LocalDateTime.parse(s, DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
    }
}

4、ResultCode

package com.keafmd.common;

import lombok.Getter;

/**
 * Keafmd
 *
 * @ClassName: ResultCode
 * @Description: 结果代码
 * @author: 牛哄哄的柯南
 * @Date: 2021-04-29 18:11
 * @Blog: https://keafmd.blog.csdn.net/
 */

@Getter
public enum ResultCode {
    NOHANDLER(404,"请求地址错误"),
    SUCCESS(200,"操作成功"),
    FAILED(500,"操作失败"),
    NOTOKEN(401,"未登录或登录已超时"),
    NOPERMISS(403,"无操作权限"),
    ;

    private Integer code;
    private String message;

    ResultCode(Integer code, String message) {
        this.code = code;
        this.message = message;
    }



}

5、AppConfig

        registry.addConverter(new LocalDateTimeConverter());
    }
}

6、DefaultExceptionHandler

package com.keafmd.config;

import com.keafmd.common.CommonResult;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;
import org.springframework.web.servlet.NoHandlerFoundException;

import javax.servlet.http.HttpServletRequest;

/**
 * Keafmd
 *
 * @ClassName: DefaultExceptionHandler
 * @Description:
 * @author: 牛哄哄的柯南
 * @Date: 2021-04-29 18:11
 * @Blog: https://keafmd.blog.csdn.net/
 */

@RestControllerAdvice
public class DefaultExceptionHandler {

    @ExceptionHandler
    public CommonResult exceptionHandler(HttpServletRequest request, Exception ex) {
        ex.printStackTrace();
        if(ex instanceof NoHandlerFoundException) {
            return CommonResult.nohandler();
        }
        return CommonResult.failed(ex.getMessage());
    }


}

9、编写后端的增删改查代码

1、在UserService接口中编写分页查询代码

package com.keafmd.service;

import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.keafmd.entity.User;
import com.baomidou.mybatisplus.extension.service.IService;

/**
 * 

 *  服务类
 * 
 *
 * @author 关注公众号：牛哄哄的柯南
 * @since 2021-04-29
 */
public interface UserService extends IService {
    Page pageList(Page page, User user);
}

2、在UserServiceImpl实现类中实现分页查询和模糊查找

package com.keafmd.service.impl;

import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.core.toolkit.StringUtils;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.keafmd.entity.User;
import com.keafmd.mapper.UserMapper;
import com.keafmd.service.UserService;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.stereotype.Service;

/**
 * 

 *  服务实现类
 * 
 *
 * @author 关注公众号：牛哄哄的柯南
 * @since 2021-04-29
 */
@Service
public class UserServiceImpl extends ServiceImpl implements UserService {

    @Override
    public Page pageList(Page page, User user) {
        if(page == null){
            page = new Page();
        }

        QueryWrapper wrapper = new QueryWrapper();
        if(user!=null && StringUtils.isNotEmpty(user.getUserName())){
            //根据user_name字段模糊查找
            wrapper.like("user_name",user.getUserName());
        }

        return super.page(page,wrapper);
    }
}

3、在UserController中编写增删改查代码

package com.keafmd.controller;


import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.keafmd.common.CommonResult;
import com.keafmd.entity.User;
import com.keafmd.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

import java.util.Arrays;

/**
 * 

 *  前端控制器
 * 
 *
 * @author 关注公众号：牛哄哄的柯南
 * @since 2021-04-29
 */
@RestController
@RequestMapping("/user")
public class UserController {
    
    @Autowired
    UserService userService;

    /**
     * 查找
     * @return
     */
    @RequestMapping("/list")
    CommonResult list(ModelMap modelMap, Page page, @ModelAttribute("user") User user) {

        page = userService.pageList(page, user);
        modelMap.addAttribute("page", page);
        return CommonResult.success(page);
    }

    @RequestMapping("/save")
    CommonResult save(User user){

        return CommonResult.success(userService.saveOrUpdate(user));

    }


    /**
     * 根据id查
     * @param id
     * @return
     */
    @RequestMapping("/getById")
    CommonResult getById(Integer id) {
        return CommonResult.success(userService.getById(id));
    }

    /**
     * 删除，逻辑删除
     * @param id
     * @return
     */
    @RequestMapping("/del")
    CommonResult del(Integer id ) {
        User user = userService.getById(id);
        user.setUserState("0");
        return CommonResult.success(userService.updateById(user));
    }


    /**
     * 批量删除
     * @param id
     * @return
     */
    @RequestMapping("/delByIds")
    CommonResult delByIds(Integer[] id) {
        /*for (Integer integer : id) {
            System.out.println(integer);
        }*/
        return CommonResult.success(userService.removeByIds(Arrays.asList(id)));
    }

}
