IDEA file->new->project
选择 Spring Initializr
此处不加依赖,直接FINISH
首先确认本地maven
已经配置好,点击File -> Settings
查看Maven
找到pom.xml
文件
直接复制此处需要的依赖
<?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>2.7.8</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.ums</groupId> <artifactId>x-admin</artifactId> <version>0.0.1-SNAPSHOT</version> <name>x-admin</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</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> <!-- web --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- mysql --> <dependency> <groupId>com.mysql</groupId> <artifactId>mysql-connector-j</artifactId> </dependency> <!-- mybatis-plus --> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.5.2</version> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-generator</artifactId> <version>3.5.2</version> </dependency> <!-- freemarker --> <dependency> <groupId>org.freemarker</groupId> <artifactId>freemarker</artifactId> </dependency> <!-- lombok --> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> <version>2.2.5.RELEASE</version> </dependency> <!-- fastjson --> <dependency> <groupId>com.alibaba.fastjson2</groupId> <artifactId>fastjson2</artifactId> <version>2.0.7</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
遇到爆红,点击右侧Maven
中刷新
按钮,等待IDEA下载依赖即可,多刷新几次,等待
用navicat
链接本地数据库,新建一个数据库xdb
新建一个 123.txt
文档,将以下SQL命令复制进去后,改名为123.sql
CREATE TABLE `x_user` ( `id` int(11) NOT NULL AUTO_INCREMENT, `username` varchar(50) NOT NULL, `password` varchar(100) DEFAULT NULL, `email` varchar(50) DEFAULT NULL, `phone` varchar(20) DEFAULT NULL, `status` int(1) DEFAULT NULL, `avatar` varchar(200) DEFAULT NULL, `deleted` INT(1) DEFAULT 0, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8; insert into `x_user` (`id`, `username`, `password`, `email`, `phone`, `status`, `avatar`, `deleted`) values('1','admin','123456','super@aliyun.com','18677778888','1','https://wpimg.wallstcn.com/f778738c-e4f8-4870-b634-56703b4acafe.gif','0'); insert into `x_user` (`id`, `username`, `password`, `email`, `phone`, `status`, `avatar`, `deleted`) values('2','zhangsan','123456','zhangsan@gmail.com','13966667777','1','https://wpimg.wallstcn.com/f778738c-e4f8-4870-b634-56703b4acafe.gif','0'); insert into `x_user` (`id`, `username`, `password`, `email`, `phone`, `status`, `avatar`, `deleted`) values('3','lisi','123456','lisi@gmail.com','13966667778','1','https://wpimg.wallstcn.com/f778738c-e4f8-4870-b634-56703b4acafe.gif','0'); insert into `x_user` (`id`, `username`, `password`, `email`, `phone`, `status`, `avatar`, `deleted`) values('4','wangwu','123456','wangwu@gmail.com','13966667772','1','https://wpimg.wallstcn.com/f778738c-e4f8-4870-b634-56703b4acafe.gif','0'); insert into `x_user` (`id`, `username`, `password`, `email`, `phone`, `status`, `avatar`, `deleted`) values('5','zhaoer','123456','zhaoer@gmail.com','13966667776','1','https://wpimg.wallstcn.com/f778738c-e4f8-4870-b634-56703b4acafe.gif','0'); insert into `x_user` (`id`, `username`, `password`, `email`, `phone`, `status`, `avatar`, `deleted`) values('6','songliu','123456','songliu@gmail.com','13966667771','1','https://wpimg.wallstcn.com/f778738c-e4f8-4870-b634-56703b4acafe.gif','0'); CREATE TABLE `x_role` ( `role_id` int(11) NOT NULL AUTO_INCREMENT, `role_name` varchar(50) DEFAULT NULL, `role_desc` varchar(100) DEFAULT NULL, PRIMARY KEY (`role_id`) ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8mb4; insert into `x_role` (`role_id`, `role_name`, `role_desc`) values('1','admin','超级管理员'); insert into `x_role` (`role_id`, `role_name`, `role_desc`) values('2','hr','人事专员'); insert into `x_role` (`role_id`, `role_name`, `role_desc`) values('3','normal','普通员工'); CREATE TABLE `x_menu` ( `menu_id` int(11) NOT NULL AUTO_INCREMENT, `component` varchar(100) DEFAULT NULL, `path` varchar(100) DEFAULT NULL, `redirect` varchar(100) DEFAULT NULL, `name` varchar(100) DEFAULT NULL, `title` varchar(100) DEFAULT NULL, `icon` varchar(100) DEFAULT NULL, `parent_id` int(11) DEFAULT NULL, `is_leaf` varchar(1) DEFAULT NULL, `hidden` tinyint(1) DEFAULT NULL, PRIMARY KEY (`menu_id`) ) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf8mb4; insert into `x_menu`(`menu_id`,`component`,`path`,`redirect`,`name`,`title`,`icon`,`parent_id`,`is_leaf`,`hidden`) values (1,'Layout','/user','/user/list','userManage','用户管理','userManage',0,'N',0),(2,'user/user','list',NULL,'userList','用户列表','userList',1,'Y',0),(3,'user/role','role',NULL,'roleList','角色列表','role',1,'Y',0),(4,'user/permission','permission',NULL,'permissionList','权限列表','permission',1,'Y',0); CREATE TABLE `x_user_role` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_id` int(11) DEFAULT NULL, `role_id` int(11) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8mb4; insert into `x_user_role` (`id`, `user_id`, `role_id`) values('1','1','1'); CREATE TABLE `x_role_menu` ( `id` int(11) NOT NULL AUTO_INCREMENT, `role_id` int(11) DEFAULT NULL, `menu_id` int(11) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8mb4;
右击xdb
选择运行SQL文件
找到123.sql
文件后运行
运行成功
打开src\main\resources\application.yml
,如果没有该文件,只有application.property
文件,则直接改其后缀为.yml
写入代码
server: port: 9999 # 端口号 spring: datasource: username: root # 数据库名 password: 1234 # 数据库密码 url: jdbc:mysql:///xdb redis: port: 6379 host: localhost logging: level: com.ums: debug
先新建一个package:sys
,空包,生成的代码会放在此处
用Mybatis-plus
来自动创建类实体的java代码
在src\test
下新建一个java类:CodeGenerator
然后写上如下代码,代码中有解释
package com.ums; import com.baomidou.mybatisplus.generator.FastAutoGenerator; import com.baomidou.mybatisplus.generator.config.OutputFile; import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine; import java.util.Collections; public class CodeGenerator { public static void main(String[] args) { String url = "jdbc:mysql:///xdb"; // 与配置文件 一致 String username = "root"; String password = "1234"; String author = "anthony"; String moduleName = "sys"; // 系统管理的代码包 String mapperLocation = "D:\\VueProj\\x-admin\\src\\main\\resources\\mapper\\" + moduleName ; String tables = "x_menu,x_role,x_role_menu,x_user,x_user_role"; // 与数据库中的表名一致,逗号隔开 FastAutoGenerator.create(url, username, password) .globalConfig(builder -> { builder.author(author) // 设置作者 // .enableSwagger() // 开启 swagger 模式 // .fileOverride() // 覆盖已生成文件 .outputDir("D:\\VueProj\\x-admin\\src\\main\\java"); // 指定输出目录 }) .packageConfig(builder -> { builder.parent("com.ums") // 设置父包名 .moduleName(moduleName) // 设置父包模块名 .pathInfo(Collections.singletonMap(OutputFile.xml, mapperLocation)); // 设置mapperXml生成路径 }) .strategyConfig(builder -> { builder.addInclude(tables) // 设置需要生成的表名 .addTablePrefix("x_"); // 设置过滤表前缀, x_menu 生成的类实体无 x_ 前缀 }) .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板,默认的是Velocity引擎模板 .execute(); } }
点击run
生成代码
上一节说过,需要记录下前端登录的响应数据格式
现在,后端来构造此格式
{"code":20000,"data":{"token":"admin-token"}}
在src\main
下新建一个package: common
然后新建package:vo
再新建一个java类Result
写入代码,有注释解释
package com.ums.common.vo; import lombok.AllArgsConstructor; import lombok.Data; import lombok.NoArgsConstructor; @Data @NoArgsConstructor @AllArgsConstructor public class Result<T> { private Integer code; // 成功失败的代码,此处定义2000为成功,2001为失败 private String message; // 消息,里面包含数据data private T data; // 未定义的数据形式 // 此处重载了四个 success 方法,有些能够返回数据,有的只返回代码或信息 public static <T> Result<T> success() { return new Result<>(20000,"success",null); } public static <T> Result<T> success(T data) { return new Result<>(20000,"success",data); } public static <T> Result<T> success(T data, String message) { return new Result<>(20000,message,data); } public static <T> Result<T> success(String message) { return new Result<>(20000,message,null); } public static<T> Result<T> fail(){ return new Result<>(20001,"fail",null); } public static<T> Result<T> fail(Integer code){ return new Result<>(code,"fail",null); } public static<T> Result<T> fail(Integer code, String message){ return new Result<>(code,message,null); } public static<T> Result<T> fail( String message){ return new Result<>(20001,message,null); } }
测试
src\main\java
中的XAdminApplication
中加入注解@MapperScan("com.ums.*.mapper")
UserController
写测试代码package com.ums.sys.controller; import com.ums.common.vo.Result; import com.ums.sys.entity.User; import com.ums.sys.service.IUserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RestController; import java.util.List; /** * <p> * 前端控制器 * </p> * * @author anthony * @since 2023-06-16 */ @RestController @RequestMapping("/user") public class UserController { @Autowired private IUserService userService; @GetMapping("/all") public Result<List<User>> getAllUser() { List<User> list = userService.list(); return Result.success(list,"查询成功"); } }
http://localhost:9999/user/all
