用Spring Boot+Vue做微人事项目第六天

前两天做了微人事登录的前端页面和后端接口，第三天则实现了前后端接口的对接，输入正确的用户名和密码之后，成功的跳转到home页。第四天做了Home页的Title制作和下拉菜单，下拉菜单有三个选项，个人中心、设置和注销登录，还做了注销登录，点击注销登录会出现提示：“此操作将注销登录，是否继续”，点是就重新跳转到登录页面，第五天做的是左边的导航菜单，现在是做服务端菜单接口的设计

menu表的各个列的意思：  menu表  服务端的菜单项数据

id:唯一标识   url:做权限控制用的   path:请求路径，对应了前端的请求路径  component:组件的名字  name:

iconCls:组件的图标    keepAlice:标记    是否保护     requrieAuth:标记  进入组件要不要登录     parentId:父菜单    enabled:菜单项是否启动

Menu类

该类本来还有KeepAlive和requireAuth两个属性，但是这两个属性不常用，所以就放到新建的Meta类里面去了，Menu新添加了一个private List

children;  children里面放的是List集合的Menu

public class Menu implements Serializable {
    private Integer id;

    private String url;

    private String path;

    private String component;

    private String name;

    private String iconCls;

    private Integer parentId;

    private Boolean enabled;

    private Meta meta;

    private List children;  //children里面放的是List集合的Menu

    private static final long serialVersionUID = 1L;

    //省略getter和setter
}

Meta类

public class Meta {

    private Boolean keepAlive;

    private Boolean requireAuth;

    //省略getter和setter
}

在MenuMapper.xml中新增

SysConfigController控制类

在controller文件夹里面新建一个SysConfigController类，该类是系统设置类

@RestController
@RequestMapping("/system/config")
public class SysConfigController {

    @Autowired
    MenuService menuService;;

    @GetMapping("/menu")
    public List getMenusByHrId(){
        return menuService.getMenusByHrId();
    }
}

MenuService业务类

要传入id了，id从哪里来，我们登录的用户信息保存到security里面

SecurityContextHolder里面有一个getContext()方法.getAuthentication()它里面的getPrincipal()，Principal它是当前登录的用户对象，然后强转成Hr对象再获取它里面的id

@Service
public class MenuService {

    @Autowired
    MenuMapper menuMapper;

    public List getMenusByHrId() {
        //要传入id了，id从哪里来，我们登录的用户信息保存到security里面
        return menuMapper.getMenusByHrId(((Hr) SecurityContextHolder.getContext().getAuthentication().getPrincipal()).getId());
        //SecurityContextHolder里面有一个getContext()方法.getAuthentication()它里面的getPrincipal()，Principal它是当前登录的用户对象，然后强转成Hr对象再获取它里面的id
    }
}

MenuMapper接口

@Repository
public interface MenuMapper {
    int deleteByPrimaryKey(Integer id);

    int insert(Menu record);

    int insertSelective(Menu record);

    Menu selectByPrimaryKey(Integer id);

    int updateByPrimaryKeySelective(Menu record);

    int updateByPrimaryKey(Menu record);

    List getMenusByHrId(Integer hrid);
}
