vue前后端分离实现功能:员工的增删改(先实现数据回显之后,再进行修改)查
一、springboot环境搭建
1、项目的数据库
/* navicat premium data transfer source server : windows source server type : mysql source server version : 80022 source host : localhost:3306 source schema : ems target server type : mysql target server version : 80022 file encoding : 65001 date: 19/12/2021 16:27:43 */ set names utf8mb4; set foreign_key_checks = 0; -- ---------------------------- -- table structure for t_emp -- ---------------------------- drop table if exists `t_emp`; create table `t_emp` ( `id` int not null auto_increment, `name` varchar(20) character set utf8mb4 collate utf8mb4_0900_ai_ci not null, `salary` double not null, `age` int not null, primary key (`id`) using btree ) engine = innodb auto_increment = 8 character set = utf8mb4 collate = utf8mb4_0900_ai_ci row_format = dynamic; -- ---------------------------- -- records of t_emp -- ---------------------------- insert into `t_emp` values (2, '杨福君', 9000, 19); insert into `t_emp` values (6, '邓正武', 18000, 25); insert into `t_emp` values (8, '王恒杰', 12000, 21); insert into `t_emp` values (9, '张西', 8000, 20); set foreign_key_checks = 1;
2、项目所需依赖
<!--继承springboot的父项目 ,放在dependencies平级下--> <parent> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-parent</artifactid> <version>2.2.5.release</version> </parent> <dependencies> <!--springboot依赖--> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter</artifactid> </dependency> <dependency> <groupid>org.mybatis.spring.boot</groupid> <artifactid>mybatis-spring-boot-starter</artifactid> <version>2.1.2</version> </dependency> <!--引入springboot的web支持--> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-web</artifactid> </dependency> <!--mysql--> <dependency> <groupid>mysql</groupid> <artifactid>mysql-connector-java</artifactid> <version>8.0.16</version> </dependency> <!--数据源连接池--> <dependency> <groupid>com.alibaba</groupid> <artifactid>druid</artifactid> <version>1.1.12</version> </dependency> <!--引入springboot的test支持--> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-test</artifactid> </dependency> </dependencies> </project>
3、application.yml文件
server: port: 8080 servlet: context-path: /ems spring: datasource: type: com.alibaba.druid.pool.druiddatasource #数据源类型 driver-class-name: com.mysql.cj.jdbc.driver #加载驱动 url: jdbc:mysql://localhost:3306/ems?usessl=false&servertimezone=utc username: root password: root mybatis: mapper-locations: classpath:com/tjcu/mapper/*mapper.xml #指定mapper文件所在的位置,其中classpath必须和mapper-locations分开 type-aliases-package: com.tjcu.entity
4、入口类
@springbootapplication @mapperscan("com.tjcu.dao") public class empapplication { public static void main(string[] args) { springapplication.run(empapplication.class,args); } }
二、vue实现前后端分离
1、前端页面
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>emp manager</title> </head> <body> <div id="app"> <center><h2>{{msg}}</h2></center> <hr/> <center> <form> 编号:<input type="text" v-model="emp.id" placeholder="添加默认为null"/><br/> 名称:<input type="text" v-model="emp.name"/><br/> 薪资:<input type="text" v-model="emp.salary"/><br/> 年龄:<input type="text" v-model="emp.age"/><br/> <input type="button" value="添加/修改" @click="add()"/> <br/> <br/> <br/> </form> </center> <table border="1" cellspacing="0" cellpadding="0" width="80%" align="center"> <tr> <td>编号</td> <td>名称</td> <td>年龄</td> <td>薪资</td> <td>操作</td> </tr> <tr v-for="(emp,index) in emps"> <td>{{index+1}}</td> <td>{{emp.name}}</td> <td>{{emp.salary}}</td> <td>{{emp.age}}</td> <td><input type="button" value="删除" @click="del(emp.id)"> <input type="button" value="修改" @click="queryone(emp.id)"></td> </tr> </table> </div> </body> </html> <script src="js/vue-min.js"></script> <script src="js/axios.min.js"></script> <script> new vue({ el:"#app" , //指定vue实例的作用范围 data:{ //定义数据 msg:"ems员工管理系统", emps:[], emp:{} }, methods:{ //定义函数 queryall(){ var vue=this; axios.get("http://localhost:8080/ems/emp/queryall") .then(function (response) { console.log(response.data); vue.emps = response.data; }).catch(function (error) { console.log(error.data); }) }, add(){ var vue=this; console.log(vue.emp); axios.post("http://localhost:8080/ems/emp/add",vue.emp) .then(function () { vue.queryall(); console.log("添加成功"); vue.emp={}; }) .catch(function () { console.log("添加失败") }) }, queryone(id){ if(window.confirm("你确定修改吗?")){ var vue=this; axios.get("http://localhost:8080/ems/emp/queryone?id="+id) .then(function (response) { //将查询的结果嫁给vue中的emp进行管理 根据双向绑定原理 emp数据变化 会影响页面 从而在表单中展示当前员工 vue.emp=response.data; console.log("查询成功"); }).catch(function () { console.log("查询失败") }) } }, del(id){ if(window.confirm("你确定删除吗?")){ var vue=this; axios.get("http://localhost:8080/ems/emp/delete?id="+id) .then(function () { vue.queryall(); console.log("删除成功") }).catch(function () { console.log("删除失败") }) } } }, created(){ this.queryall(); } }) </script>
2、springboot控制层
/** * @author 王恒杰 * @date 2021/12/17 15:52 * @description: */ @controller @crossorigin @responsebody public class empcontroller { @autowired private empservice empservice; @requestmapping("/emp/queryall") public list<emp> queryall(){ list<emp> emps = empservice.showemp(); return emps; } /** * 删除 * @param id */ @requestmapping("/emp/delete") public void delete(integer id){ empservice.deletebyid(id); } @requestmapping("/emp/add") public void add(@requestbody emp emp){ if(emp.getid()!=0){ empservice.updateemp(emp); }else { emp.setid(null); empservice.insertemp(emp); } } @requestmapping("/emp/queryone") public emp query(integer id){ emp emp = empservice.selectempbyid(id); return emp; } }
3、mapper文件
<mapper namespace="com.tjcu.dao.empdao"> <insert id="insertemp"> insert into t_emp values (#{id}, #{name}, #{salary}, #{age}) </insert> <select id="showemp" resulttype="emp"> select * from t_emp </select> <update id="updateemp"> update t_emp <set> <if test="name!=null"> name=#{name}, </if> <if test="salary!=null"> salary=#{salary}, </if> <if test="age!=null"> age=#{age} </if> </set> where id=#{id} </update> <delete id="deletebyid"> delete from t_emp where id=#{id} </delete> <select id="selectempbyid" resulttype="emp"> select * from t_emp where id=#{id} </select> </mapper>
