Spring安全性@PreAurhorize hasRole（）属性注入 [英] Spring security @PreAurhorize hasRole() properties injection

问题描述

假设我的spring安全性和属性配置正确，我想使用属性中的角色名称，如

assuming that my spring security and properties are configured properly, I would like to use role name from property like

@PreAuthorize("hasRole('${role.rolename}')")
public void method() {}

我在上面的代码示例中尝试了但它不起作用（需要'$ {role.rolename}'字符串作为比较的角色）

I have tried like in above code sample but it does not work ( it takes '${role.rolename}' String as role to compare)

如果我切换到

@PreAuthorize("hasRole('ROLE_ADMIN')")
public void method() {}

它运作正常。
我对这种用法的动机是在各种环境下的应用程序测试中具有更好的灵活性。

it works just fine. My motivation to such usage is better flexibility in application tests on various environments.

推荐答案

尝试删除''标志：

@PreAuthorize("hasRole(${role.rolename})")
public void method() {}

编辑。我确信有更好的方法，但作为一种解决方法，你可以在某个bean上调用一些方法：

EDIT. I am sure that there is a better way, but as a workaround you can call some method on some bean:

@Component("appVariablesHolder")
public class AppVariablesHolder {

    @Value("${role.rolename}") 
    private String someRole;

    public String getSomeRole() {
        return this.someRole;
    }
}

@PreAuthorize("hasRole(@appVariablesHolder.getSomeRole())")
public void method() {}
