Shiro完整架构图
Shiro认证过程
Shiro授权的内部处理机制
Shiro 支持三种方式的授权
1.编程式:通过写if/else 授权代码块完成:
Subject subject = SecurityUtils.getSubject();
if(subject.hasRole(“admin”)) {
//有权限
} else {
//无权限
}
2.注解式:通过在执行的Java方法上放置相应的注解完成:
@RequiresRoles("admin")
public void hello() {
//有权限
}
3.JSP/GSP 标签:在JSP/GSP 页面通过相应的标签完成:
<shiro:hasRole name="admin">
<!— 有权限—>
</shiro:hasRole>
实际与web系统集成使用后两种方式
