基于SpringBoot+Vue前后端分离的仓库管理系统后端.zip

# 1. 项目概述 项目是基于SpringBoot+Vue前后端分离的仓库管理系统 后端：SpringBoot + MybatisPlus 前端：Node.js + Vue + element-ui 数据库：mysql # 2. 创建后端项目 ## 2.1 创建模块 1. 创建项目模块 2. 导入项目依赖 pom.xml ```xml <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.7.5</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.wms</groupId> <artifactId>Warehouse-System</artifactId> <version>0.0.1-SNAPSHOT</version> <name>Warehouse-System</name> <description>Warehouse management system</description> <properties> <java.version>11</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.30</version> <scope>runtime</scope> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <!--mybatisPlus--> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.4.1</version> </dependency> <!--代码生成器--> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-generator</artifactId> <version>3.4.1</version> </dependency> <dependency> <groupId>org.freemarker</groupId> <artifactId>freemarker</artifactId> <version>2.3.30</version> </dependency> <dependency> <groupId>com.spring4all</groupId> <artifactId>spring-boot-starter-swagger</artifactId> <version>1.5.1.RELEASE</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project> ``` ## 2.2 加入MybatisPlus支持 1. 导入依赖 ```xml <!--mybatisPlus--> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.5.2</version> </dependency> ``` 2. 创建并连接数据库  3. 配置端口和数据源 application.yml ```yml server: port: 8002 spring: datasource: url: jdbc:mysql://localhost:3306/wms?useUnicode=true&characterEncoding=utf-8&serveTimezone=UTC driver-class-name: com.mysql.cj.jdbc.Driver username: root password: 123456 ``` 4. 编写实体类 ```java @Data public class User { private int id; private String no; private String name; private String password; private int sex; private int roleId; private String phone; private String isvalid; } ``` 5. 编写Mapper接口 ```java @Mapper public interface UserMapper extends BaseMapper<User> { public List<User> selectAll(); } ``` 6. 编写Service接口 ```java public interface UserService extends IService<User> { public List<User> selectAll(); } ``` 7. 编写Service实现类 ```java @Service public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements UserService { @Autowired private UserMapper userMapper; public List<User> selectAll(){ return userMapper.selectAll(); } } ``` 8. 编写配置文件 UserMapper.xml ```xml <?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="com.wms.mapper.UserMapper"> <select id="selectAll" resultType="com.wms.entity.User"> select * from user </select> </mapper> ``` 9. 编写测试代码 ```java @RestController public class testController { @Autowired private UserService userService; @GetMapping public List<User> test(){ return userService.selectAll(); } } ``` 10. 测试结果  # 3. 代码生成器 > 简化开发：删除之前编写的实体类、接口、实现类、配置文件以及测试类，利用MyBatisPlus代码生成器自动生成代码 1. 导入依赖 > 注意：MybatisPlus版本用3.4.1，3.5版本的MybatisPlus会报错！ ```xml <!--代码生成器--> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-generator</artifactId> <version>3.4.1</version> </dependency> <dependency> <groupId>org.freemarker</groupId> <artifactId>freemarker</artifactId> <version>2.3.30</version> </dependency> ``` 2. 编写代码生成器 > 参考MybatisPlus官网：https://baomidou.com/pages/d357af/ ```java package com.wms.common;

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"); gc.setOutputDir(projectPath + "/src/main/java"); gc.setAuthor("linsuwen"); gc.setOpen(false); gc.setSwagger2(true); //实体属性 Swagger2 注解 gc.setBaseResultMap(true); // XML ResultMap gc.setBaseColumnList(true); // XML columList //去掉service接口首字母的I, 如DO为User则叫UserService
