充电宝项目——若依权限管理

若依的权限管理分为前后端：

• 前端：主要使用【标识】

• 后端：使用注解区分如角色、是否需要登录等，也可以使用【标识】

@RequiresLogin("admin")
public AjaxResult getInfo(...) {
    return AjaxResult.success(...);
}

@RequiresPermissions("system:user:add")
public AjaxResult save(...) {
    return AjaxResult.success(..);
}

RequiresPermissions({"system:user:add", "system:user:edit"})
public AjaxResult save(...)
{
    return AjaxResult.success(...);
}

@RequiresPermissions(value = {"system:user:add", "system:user:edit"}, logical = Logical.OR)  
public AjaxResult save(...)  
{  
    return AjaxResult.success(...);  
}

@RequiresRoles("admin")  
public AjaxResult save(...)  
{  
    return AjaxResult.success(...);  
}

@RequiresRoles({"admin", "common"})  
public AjaxResult save(...)  
{  
    return AjaxResult.success(...);  
}

@RequiresRoles(value = {"admin", "common"}, logical = Logical.OR)  
public AjaxResult save(...)  
{  
    return AjaxResult.success(...);  
}

充电宝项目——代码生成

通过修改模块 share-gen 的配置，在若依前端页面使用代码生成功能，一键创建各种CRUD和前端页面和菜单SQL

充电宝项目——若依日志模块

若依日志用了注解+AOP的组合，将使用注解标识的controller接收请求时进行记录。

充电宝项目——openfeign发送请求

使用模块 share-api 来进行编写openfeign的请求，如：

/**
 * 文件服务
 *
 * @author share
 */
@FeignClient(contextId = "remoteFileService", value = ServiceNameConstants.FILE_SERVICE, fallbackFactory = RemoteFileFallbackFactory.class)
public interface RemoteFileService
{
    /**
     * 上传文件
     *
     * @param file 文件信息
     * @return 结果
     */
    @PostMapping(value = "/upload", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
    public R<SysFile> upload(@RequestPart(value = "file") MultipartFile file);
}

可以在后端发送请求来获取需要的数据：

...
            R<SysFile> fileResult = remoteFileService.upload(file);
...

充电宝项目——微信登录

微信登录流程参考：

uni-app微信小程序——对接Spring实现微信登录 | zxb的博客

这里主要新加了微信官方的sdk，方便开发：

<dependency>
            <groupId>com.github.binarywang</groupId>
            <artifactId>weixin-java-miniapp</artifactId>
</dependency>

简单的demo：

    /**
     * 微信授权登录
     *
     * @param code
     * @return
     */
    public UserInfo wxLogin(String code) {
        String openId = null;
        try {
            // 获取openId
            WxMaJscode2SessionResult sessionInfo = wxMaService.getUserService().getSessionInfo(code);
            openId = sessionInfo.getOpenid();
            log.info("【小程序授权】openid={}", openId);
        } catch (WxErrorException e) {
            throw new ServiceException("微信登录异常");
        }

        UserInfo userInfo = this.getOne(new LambdaQueryWrapper<UserInfo>().eq(UserInfo::getWxOpenId, openId));

        if (userInfo == null) {
            userInfo = new UserInfo();
            userInfo.setNickname(String.valueOf(System.currentTimeMillis()));
            userInfo.setAvatarUrl("https://oss.aliyuncs.com/aliyun_id_photo_bucket/default_handsome.jpg");
            userInfo.setWxOpenId(openId);
            this.save(userInfo);
        }
        return userInfo;
    }

优点：

• 对常见的功能进行封装（不需要手动再向官方发送请求）
