关于注解拦截器的问题

Question

springboot项目里想加个token拦截，用的是注解拦截的方法，目前的问题是在
在controller方法接口头上添加了这个注解，也就是说没有登录不能访问这个接口。但实际效果是可以访问。求点拨。

    @UserLoginToken(required = false)

注解如下

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;


@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
public @interface PassToken {
    boolean required() default true;
}

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;


/*RetentionPolicy.RUNTIME:这种类型的Annotations将被JVM保留,
所以他们能在运行时被JVM或其他使用反射机制的代码所读取和使用。*/
@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
public @interface UserLoginToken {
    boolean required() default true;
}

这是处理工具类

    }

Answer 1

把你controller层代码放出来呀。提问题要全面点。
还有你是先判断@PassToken 注解的，如果controller加入了这个注解，就算你加上@UserLoginToken 也会访问到。
我这边是这么写的：
