这上面的代码当然都是放login.vue里的,嘿嘿,分开点好看点。
前端代码运行
右键点击你的web项目选择在集成终端中打开

然后输入npm run serve,出现下图ctrl+左键点击进入前端页面。

后端代码

public String hello() {
return "hello wms";
}
@Autowired
private IUserService userService;
@Autowired
private MenuService menuService;
// 登录
@PostMapping("/login")
public Result Login(@RequestBody User user) {
List<User> list = userService.lambdaQuery().eq(User::getAccount, user.getAccount())

if (list.size() > 0) {
User user1 = (User) list.get(0);

HashMap<String, Object> res = new HashMap<>();
res.put("user", user1);
res.put("menu", menuList);
return Result.suc(res);
}
return Result.fail();
}
}
嘿嘿你看见了我的封装类吧 result,这也解释了为啥我的axios获取数据要两个then才能获取到,因为我自己封装了一层嘛。
package com.example.wsm.common;
import lombok.Data;
@Data
public class Result {
private int code; // 编码 200/400
private String msg;// 成功/失败
private Long total;// 总记录数
private Object data;// 数据
public static Result fail() {
return result(400, "失败", 0L, null);
}
public static Result suc() {
return result(200, "成功", 0L, null);
}
public static Result suc(Object data) {
return result(200, "成功", 0L, data);
}
public static Result suc(Long total, Object data) {
return result(200, "成功", total, data);
}
private static Result result(int code, String msg, Long total, Object data) {
Result res = new Result();
res.setCode(code);
res.setMsg(msg);
res.setTotal(total);
res.setData(data);
return res;
}
}

CodeGenerator类代码自动生成
mybatis可以不用写xml,用sql语言封装好了的,创个entity实体类,service,impl,mapper,mapper实现类xml,我这些其实是用MyBatisplus里的CodeGenerator代码自动生成的。只需在数据库创建表,然后在后端运行代码输入该表名称就会自动生成entity,service,impl,mapper,mapper实现类xml,如果运行不了,那就是你还有啥依赖没下载哦。
mybatis-plus下载
要有springboot的依赖,springboot2 mybatisplus依赖用maven下载
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>

</dependency>
springboot3 mybaitsplus依赖用 maven 下载
