除了 hasRole 方法,还可以使用其他安全表达式,例如:
1. hasAnyRole:判断用户是否具有指定角色中的任意一个,用法如下:
```html
<div sec:authorize="hasAnyRole('ROLE_ADMIN','ROLE_USER')">具有ROLE_ADMIN或ROLE_USER角色的用户都能看到这个元素</div>
```
2. hasAuthority:判断用户是否具有指定权限,用法如下:
```html
<div sec:authorize="hasAuthority('USER_READ')">只有具有USER_READ权限的用户才能看到这个元素</div>
```
3. hasAnyAuthority:判断用户是否具有指定权限中的任意一个,用法如下:
```html
<div sec:authorize="hasAnyAuthority('USER_READ','USER_WRITE')">具有USER_READ或USER_WRITE权限的用户都能看到这个元素</div>
```

```xml
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-springsecurity5</artifactId>
</dependency>
```
同时,在 Thymeleaf 模板中需要添加以下命名空间:
```html
<html xmlns:sec="http://www.thymeleaf.org/extras/spring-security">
```
这样就可以愉快地在 Thymeleaf 模板中使用 Spring Security 的安全表达式了!
