闲来无事研究了一个日志拦截，

package com.rxyb.web.annotation;
    
    import java.lang.annotation.*;
    
    @Target(ElementType.METHOD)//作用于方法、不能是构造方法
    @Retention(RetentionPolicy.RUNTIME)//在运行时可以通过反射获取到,jvm会读取注解,同时保存在class文件中
    @Documented//说明该注解将被包含在javadoc中
    public @interface LogAnnotation {
        public String moudle() default "";
    }
