### 与权限有关的注解
|
||||
|
||||
`@Anonymous`注解用于配置公开接口
|
||||
|
||||
`@PreAuthorize`注解用于配置接口要求用户拥有某些权限才可访问，它拥有如下方法
|
||||
|
||||
| 方法 | 参数 | 描述 |
|
||||
| ----------- | ------ | ---------------------------------------------- |
|
||||
| hasPermi | String | 验证用户是否具备某权限 |
|
||||
| lacksPermi | String | 验证用户是否不具备某权限，与 hasPermi逻辑相反 |
|
||||
| hasAnyPermi | String | 验证用户是否具有以下任意一个权限 |
|
||||
| hasRole | String | 判断用户是否拥有某个角色 |
|
||||
| lacksRole | String | 验证用户是否不具备某角色，与 isRole逻辑相反 |
|
||||
| hasAnyRoles | String | 验证用户是否具有以下任意一个角色，多个逗号分隔 |
|
||||
|
||||
```java
|
||||
@PreAuthorize("@ss.hasPermi('system:user:list')")
|
||||
@PreAuthorize("@ss.lacksPermi('system:user:list')")
|
||||
@PreAuthorize("@ss.hasAnyPermi('system:user:add,system:user:edit')")
|
||||
```
|
||||
|
||||
`@DataScope`注解用于配置接口数据权限
|
||||
|
||||
* `deptAlias`用于指定部门表的别名;
|
||||
* `userAlias`用于指定用户表的别名;
|
||||
* 实体需要继承BaseEntity类;
|
||||
* `全部数据权限`、`自定数据权限`、`部门数据权限`、`部门及以下数据权限`、`仅本人数据权限`五种权限模式在后台角色管理界面配置数据权限
|
||||
|
||||
```java
|
||||
// 部门数据权限注解
|
||||
@DataScope(deptAlias = "d")
|
||||
// 部门及用户权限注解
|
||||
@DataScope(deptAlias = "d", userAlias = "u")
|
||||
```
|
||||
|
||||
1. 使用注解
|
||||
|
||||
```java
|
||||
|
||||
@DataScope(deptAlias = "d", userAlias = "u")
|
||||
public List<...> select(...)
|
||||
{
|
||||
return mapper.select(...);
|
||||
}
|
||||
```
|
||||
|
||||
2. 配置mybatis的xml
|
||||
|
||||
```xml
|
||||
<select id="select" parameterType="..." resultMap="...Result">
|
||||
<include refid="select...Vo"/>
|
||||
<!-- 数据范围过滤 -->
|
||||
${params.dataScope}
|
||||
</select>
|
||||
```
|
||||
|
||||
### 安全工具类
|
||||
|
||||
com.ruoyi.common.utils.SecurityUtils
|
||||
|
||||
| 方法 | 参数 | 返回 | 描述 |
|
||||
| ------------ | ------ | ---------- | ------------------------ |
|
||||
| getUserId | 无 | Long | 获取当前用户ID |
|
||||
| getDeptId | 无 | Long | 获取当前部门ID |
|
||||
| getUsername | 无 | String | 获取当前用户账户 |
|
||||
| getLoginUser | 无 | LonginUser | 获取当前登录用户代理 |
|
||||
| hasPermi | String | boolean | 验证用户是否具备某权限 |
|
||||
| hasRole | String | boolean | 验证用户是否拥有某个角色 |
