spring里使用Annotaion配置aop出现了问题，请高手帮帮忙啊，谢谢了！

写了一个Interceptor



package com.spring.aop;


import org.aspectj.lang.annotation.After;

import org.aspectj.lang.annotation.Aspect;

import org.aspectj.lang.annotation.Before;

import org.aspectj.lang.annotation.Pointcut;

import org.springframework.stereotype.Component;


@Aspect

@Component

public class LogInterceptor {


	@Pointcut("execution(public * com.spring.aop.AopService.say(..))")

	public void myMethod(){


	};

	@Before("myMethod()")

	public void before(){

		System.out.println("method before");

	}

	@After("myMethod()")

	public void after(){

		System.out.println("method end");

	}

}

一个需要被拦截的类：AopService



package com.spring.aop;


import org.springframework.stereotype.Component;


@Component("aopservice")

public class AopService {

	String name = "aa";

	public String getName() {

		return name;

	}

	public void setName(String name) {

		this.name = name;

	}

	public void say(){

		System.out.println("hello!");

	}

}

applicationContext.xml文件里的内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       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-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">
<context:annotation-config />
<context:component-scan base-package="com.spring"></context:component-scan>
<aop:aspectj-autoproxy/>
</beans>

Test类：
package com.spring.aop;

import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;

public class Test {
@org.junit.Test
public void test(){
XmlBeanFactory f = new XmlBeanFactory(new ClassPathResource("applicationContext.xml"));
AopService service = (AopService) f.getBean("aopservice");
service.say();
}
}
后台打印：
log4j:WARN No appenders could be found for logger (org.springframework.beans.factory.xml.XmlBeanDefinitionReader).
log4j:WARN Please initialize the log4j system properly.
hello!

不知道为什么并没有打印拦截器所要输出的内容，不知道问题出在哪儿了。因为是初学spring，还不是很懂，希望各位能帮帮忙！谢谢啦！

5 个解决方案

#1

要引近来Spring 的log jar包和log.properties在Spring下载下来的文件里面好好找找，学一遍，这辈子就那样了

#2

问题解决了！
刚开始的是用Myeclipse添加的spring的属性，怎么都打印不出来；后来我重新自己手动加入下载的jar后，后台就能够打印出Inteceptor要打印的内容了！

#3

而且我发现在Test类里，

XmlBeanFactory f = new XmlBeanFactory(new ClassPathResource("applicationContext.xml"));

这样是不会打印出拦截器要求输出的内容，而换成ClassPathXmlApplicationContext就可以。
这是为什么呢？

package com.sxzlc.test.rc4;

public class RC4 {
public static byte[] RC42(byte[] aInput, byte[] aKey) {
int[] iS = new int[256];
byte[] iK = new byte[256];

for (int i = 0; i < 256; i++)
iS[i] = i;

int j = 1;

for (short i = 0; i < 256; i++) {
iK[i] = (byte) aKey[i%aKey.length];
}

j = 0;

for (int i = 0; i < 256; i++) {
j = (j + iS[i] + iK[i]) &0xff;
int temp = iS[i]&0xff;
iS[i] = iS[j]&0xff;
iS[j] = temp;
}

int i = 0;
j = 0;

for (int x = 0; x < aInput.length; x++) {
i = (i + 1) &0xff;
j = (j + iS[i]) &0xff;
int temp = iS[i]&0xff;
iS[i] = iS[j]&0xff;
iS[j] = temp;
int t = ((iS[i] + iS[j] ))&0xff;
int iY = iS[t];
byte iCY = (byte) (iY&0xff);
aInput[x] = (byte) ((aInput[x]^iCY)&0xff);
}

return aInput;

}

public static void main(String[] args)
{
String inputStr = "你们好啊";
String key = "961633";
byte[] bytes = inputStr.getBytes();
//打印加密后的字符串
bytes = RC4.RC42(inputStr.getBytes(), key.getBytes());
inputStr = new String(bytes);
System.out.println( inputStr );
//打印加密后的字符串
bytes = RC4.RC42(inputStr.getBytes(), key.getBytes());
inputStr = new String(bytes);
System.out.println( inputStr );
}

}
