1创建拦截器注解
import javax.interceptor.InterceptorBinding;
import java.lang.annotation.*;

@Inherited
@InterceptorBinding
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD,ElementType.TYPE})
public @interface LogEvent {
}

2创建拦截器

import javax.interceptor.AroundInvoke;
import javax.interceptor.Interceptor;
import javax.interceptor.InvocationContext;

@LogEvent
@Interceptor
public class LogEventInterceptor {

    @AroundInvoke
    public Object logEvent(InvocationContext ctx) throws Exception {

        System.out.println("method:"+ctx.getMethod().getName()+"param:"+ctx.getParameters());
        return ctx.proceed();
    }
}

3在需要拦截的方法或类上加上@LogEvent 注解接口
