SpringSecurity之授权

授权介绍

Spring Security 中的授权分为两种类型：

基于角色的授权：以用户所属角色为基础进行授权，如管理员、普通用户等，通过为用户分配角色来控制其对资源的访问权限。
基于资源的授权：以资源为基础进行授权，如 URL、方法等，通过定义资源所需的权限，来控制对该资源的访问权限。

Spring Security 提供了多种实现授权的机制，最常用的是使用基于注解的方式，建立起访问资源和权限之间的映射关系。

其中最常用的两个注解是 @Secured 和 @PreAuthorize。@Secured 注解是更早的注解，基于角色的授权比较适用，@PreAuthorize 基于 SpEL 表达式的方式，可灵活定义所需的权限，通常用于基于资源的授权。

}

Controller类数据

    @ResponseBody@RequestMapping("/o_f")@PreAuthorize("hasAnyAuthority('order:manager:analysis')")public String o_f() {return "订单分析";}@ResponseBody@RequestMapping("/b_add")@PreAuthorize("hasAnyAuthority('book:manager:add')")public String b_add() {return "书籍新增";}

需要添加一个规则，判断是否有权限，我这个放在WebSecurityConfig类上

@EnableGlobalMethodSecurity(prePostEnabled = true)
