#端口
server:
  port: 8090
 
spring:
  datasource:
    url: jdbc:mysql://localhost:3306/vue?serverTime=UTC&useUnicode=true&charcterEncoding=utf-8&useSSl=flase
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: root    //账号
    password: 123456   //密码

 3.3 编写测试代码

3.3.1 创建实体类User

@Data
@EqualsAndHashCode(callSuper = false)
@ApiModel(value="User对象", description="")
public class User implements Serializable {
 
    private static final long serialVersionUID = 1L;
 
    @TableId(value = "id", type = IdType.AUTO)
    private Integer id;
 
    @ApiModelProperty(value = "账号")
    private String no;
 
    @ApiModelProperty(value = "名字")
    private String name;
 
    @ApiModelProperty(value = "密码")
    private String password;
 
    private Integer age;
 
    @ApiModelProperty(value = "性别")
    private Integer sex;
 
    @ApiModelProperty(value = "电话")
    private String phone;
 
    @ApiModelProperty(value = "角色 0超级管理员,1管理员,2普通账号")
    private Integer roleId;
 
    @ApiModelProperty(value = "是否有效，Y有效，其他无效")
    @TableField("isValid")
    private String isvalid;
 
}

3.3.2 创建mapper接⼝UserMapper

@Mapper
public interface UserMapper extends BaseMapper<User> {
 public List<User> selectAll();
}

public interface UserService extends IService<User> {
 public List<User> selectAll();
}

@Service
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements
UserService {
 @Resource
 private UserMapper userMapper;
 @Override
 public List<User> selectAll() {
 return userMapper.selectAll();
 }
}

<?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>

3.3.4 测试类

@RestController
public class HelloController {
 @Autowired
 private UserService userService;
 @GetMapping
 public List<User> hello(){
 return userService.selectAll();
 }
}

 3.4 实现增删改查

@RestController
@RequestMapping("/user")
public class UserController {
 
    @Autowired
    private UserService userService;
 
    /**
     * 查询所有
     */
    @GetMapping("/list")
    public List<User> list() {
        return userService.list();
    }
 
 
    /**
     * 修改
     */
    @PostMapping("/mod")
    public boolean mod(@RequestBody User user) {
        return userService.updateById(user);
    }
 
    /**
     * 增加或修改
     */
    @PostMapping("/saveOrMod")
    public boolean saveOrMod(@RequestBody User user) {
        return userService.saveOrUpdate(user);
    }
 
    /**
     * 删除
     */
    @GetMapping("/delete")
    public boolean delete(Integer id) {
        return userService.removeById(id);
    }
 
    /**
     * 查询(模糊，匹配)
     */
    @PostMapping("/listP")
    public Result ListP(@RequestBody User user) {
        LambdaQueryWrapper<User> lambdaQueryWrapper = new LambdaQueryWrapper();
        if (StringUtils.isNotBlank(user.getName())) {
            lambdaQueryWrapper.like(User::getName, user.getName());
        }
        //完全匹配
//        lambdaQueryWrapper.eq(User::getName,user.getName());
        return Result.suc(userService.list(lambdaQueryWrapper));
    }
 
}
 

3.5 实现分页功能

3.5.1 添加分页拦截器

@Configuration
public class MybatisPlusConfig {
 @Bean
 public MybatisPlusInterceptor mybatisPlusInterceptor() {
 MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
 interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
 return interceptor;
 }
}

3.5.2 编写mapper方法

@Mapper
public interface UserMapper extends BaseMapper<User> {
 
    IPage pageC(IPage<User> page);
 
}

3.5.3 实现类 

    @PostMapping("/listPageC")
    public List<User> listPageC(@RequestBody QueryPageParam query) {
        HashMap param = query.getParam();
        String name = (String) param.get("name");
        System.out.println("name===" + (String) param.get("name"));
 
        Page<User> page = new Page();
        page.setCurrent(query.getPageNum());
        page.setSize(query.getPageSize());
 
        LambdaQueryWrapper<User> lambdaQueryWrapper = new LambdaQueryWrapper();
        lambdaQueryWrapper.like(User::getName, name);
 
        //IPage result = userService.pageC(page);
        IPage result = userService.pageCC(page, lambdaQueryWrapper);
 
        System.out.println("total==" + result.getTotal());
 
        return result.getRecords();
    }

四、前端

1.使用vue脚手架创建前端项目

安装脚手架 npm install -g @vue/cli
创建项目：vue init webpack 项目名

2.导入Element-ui

1. 安装命令 
 
npm i element-ui -S
 
2. mainjs全局引⼊
 
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(ElementUI);
 
3. 测试是否引⼊成功

3. 安装axios与处理跨域

1.安装axios
npm install axios --save
 
2.在main.js全局引⼊axios
import axios from ‘axios’;
Vue.prototype.$axios =axios;

五、数据库简介

数据库的账号密码记得改为自己的

url: jdbc:mysql://localhost:3306/springboot?serverTime=UTC&useUnicode=true&charcterEncoding=utf-8&useSSl=flase
//springboot为我用的数据库的名字
 
driver-class-name: com.mysql.cj.jdbc.Driver
 
username: root    //账号
 
password: 123456   //密码
