spring aop aspectJ 使用XML配置AOP，但同一个切入方法执行二次的问题

Question

spring aop aspectJ 使用XML配置AOP，只增加了一个切入点，但同一个切入方法执行二次的问题

Spring AOP XML配置文件：
<?xml version="1.0" encoding="UTF-8"?>
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-4.0.xsd">

<bean id="userManager" class="org.drsoft.business.UserManagerImpl">

</bean>

<aop:config>
    <aop:pointcut expression="execution(public * org.drsoft.business.*.* (..))" id="allBefore"/>

    <aop:aspect id="xmlAspect" ref="xmlAspect">
        <aop:before method="BeforeLog" pointcut-ref="allBefore"/>
    </aop:aspect>
</aop:config>

<bean id="xmlAspect" class="org.drsoft.aop.XMLAspect"/>

<bean
    class="org.springframework.aop.aspectj.annotation.AnnotationAwareAspectJAutoProxyCreator">
</bean>

切面类：
package org.drsoft.aop;

public class XMLAspect {
public void BeforeLog() {
System.out.println("XMLAspect BeforeLog Time=" + System.currentTimeMillis());
}
}
Main方法：
package org.drsoft;

import org.drsoft.business.UserManager;
import org.drsoft.utils.SpringUtils;

public class SpringAOPXMLMain {
public static void main(String[] args) {
UserManager userManager = SpringUtils.getBean("userManager", UserManager.class);

    userManager.signUser();
}

}

输出结果：
XMLAspect BeforeLog Time=1485916445019
XMLAspect BeforeLog Time=1485916480819
UserManagerImpl signUser Timestamp=1485916483706

Answer 1

代码调整，输出了方法名称，根据输出结果，发现是同一个方法执行了多次
public void BeforeLog(JoinPoint joinPoint) {
System.out.println("XMLAspect BeforeLog Time=" + System.currentTimeMillis() + "\tName="
+ joinPoint.getSignature().getName());
}

输出结果：
XMLAspect BeforeLog Time=1485928792439  Name=signUser

XMLAspect BeforeLog Time=1485928792441 Name=signUser
UserManagerImpl signUser Timestamp=1485928792441
