我正在努力测试受Spring Security保护的URL的访问控制.
配置如下所示:
http
.authorizeRequests()
.antMatchers("/api/user/**", "/user").authenticated()
.antMatchers("/api/admin/**", "/templates/admin/**", "/admin/**").hasAuthority("ADMIN")
.anyRequest().permitAll();

测试类看起来像这样:

public void …Run Code Online (Sandbox Code Playgroud) 我想创建一个函数,该函数将返回一个函数,该函数是参数x上f的n倍的函数,即f(f(f ... f(x)...))。这是我的代码:
def repeated(f: Int => Int, n: Int) = {
var tek: Int => Int = f
for (i <- 0 to n) {
tek = x => f(tek(x))
}
tek
}

我知道这不是在Scala中执行此操作的正确方法,我只想了解幕后发生的事情。
调用它repeated(x => x + 1, 5)(1)会导致堆栈溢出。
我在调试器中注意到的是,重复完成后将执行for循环内的行。似乎是惰性启动,也许for循环的主体是按名称传递的lambda?
