Building Applications with Spring 5 and Vue.js 2

@SecurityCheck

Now, let's implement a simplified security check to our Messages App. We will create an @SecurityCheck annotation, which can be applied to any method to perform a security check.

Here is what the @SecurityCheck annotation looks like:

@Target(ElementType.METHOD)@Retention(RetentionPolicy.RUNTIME)public @interface SecurityCheck {}

As you can see, this is a simple annotation that can be applied to methods.

And here is how the SecurityChecker aspect appears:

package app.messages;...import org.aspectj.lang.ProceedingJoinPoint;import org.aspectj.lang.annotation.Around;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Pointcut;...@Aspect@Componentpublic class SecurityChecker {  ...  @Pointcut("@annotation(SecurityCheck)") ...
