AOP问题，烦恼我一天了！

问题：
切面类是记录CD里每个磁道的播放量的，每次播放都会记录磁道，但记录的那个bean和测试类里的实例不是一个，怎么解决，谢谢各位大佬！
-------------------------------------------------------------------------------------
测试类

package soundsystem;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = TrackCounterConfig.class)
public class CDPlayerTest {

    @Autowired
    private CompactDisc cd;

    @Autowired
    private TrackCounter counter;

    @Test
    public void testCDPlayer(){
        cd.playTrack(1);
        cd.playTrack(2);
        System.out.println(counter.getTrackCounts());
        System.out.println(counter.getPlayCount(1));
        System.out.println(counter.getPlayCount(2));
        System.out.println(counter.getPlayCount(3));
    }

}

配置类

package soundsystem;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.EnableAspectJAutoProxy;

import java.util.ArrayList;
import java.util.List;

@Configuration
@EnableAspectJAutoProxy
public class TrackCounterConfig {

    @Bean
    public CompactDisc sgtPeppers(){
        BlankCompactDisc cd = new BlankCompactDisc();
        cd.setTitle("Sgt. Pepper's Lonely Hearts Club Band");
        cd.setArtist("The Beatles");
        List<String> tracks = new ArrayList<>();
        tracks.add("Sgt. Pepper's Lonely Hearts Club Band");
        tracks.add("With a Little help from My Friends");
        tracks.add("Lucy in the Sky with Diamonds");
        tracks.add("Getting Better");
        tracks.add("Fixing a Hole");
        cd.setTracks(tracks);
        return cd;
    }

    @Bean
    public TrackCounter trackCounter(){
        return new TrackCounter();
    }

}

CD类

package soundsystem;

import org.springframework.stereotype.Component;

import java.util.List;

@Component
public class BlankCompactDisc implements CompactDisc {

    private String title;
    private String artist;
    private List<String> tracks;

    @Override
    public void play() {
        System.out.println("Playing " + title + " by " + artist);
        for(String track:tracks){
            System.out.println("-Track: " + track);
        }
    }

    @Override
    public void playTrack(int trackNumber) {
        System.out.println(tracks.get(trackNumber));
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public void setArtist(String artist) {
        this.artist = artist;
    }

    public void setTracks(List<String> tracks) {
        this.tracks = tracks;
    }
}

切面类

package soundsystem;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

import java.util.HashMap;
import java.util.Map;

@Aspect
public class TrackCounter {

    private Map<Integer, Integer> trackCounts = new HashMap<>();

    @Pointcut(
            "execution(* soundsystem.CompactDisc.playTrack(int))" + " && args(trackNumber)"
    )
    public void trackPlayed(int trackNumber) {}

    @Before("trackPlayed(trackNumber)")
    public void countTrack(int trackNumber) {
        int currentCount = getPlayCount(trackNumber);
        currentCount++;
        trackCounts.put(trackNumber, currentCount);
        System.out.println("开始记录磁盘：\n" + trackCounts);
    }

    public int getPlayCount(int trackNumber) {
        return trackCounts.containsKey(trackNumber) ? trackCounts.get(trackNumber) : 0;
    }

    public Map<Integer, Integer> getTrackCounts() {
        return trackCounts;
    }
}

[十八道胡同]

意思是test类里面的 TrackCounter和Bean里面的TrackCounter 实例 不一样？

引用 1 楼 LCL_data 的回复:

对的 现在发现Aspect注解的类不是bean 问题已经解决了 但我还想知道如何让这个变成一个bean

[十八道胡同]

找到原因了吗？

你用xml文件配置aop，测试类引入xml试试

[:：]

<!-- 配置切面的Bean --> <bean id="sysAspect" class="com.example.aop.SysAspect"/> <!-- 配置AOP --> <aop:config> <!-- 配置切点表达式 --> <aop:pointcut id="pointcut" expression="execution(public * com.example.controller.*Controller.*(..))"/> <!-- 配置切面及配置 --> <aop:aspect order="3" ref="sysAspect"> <!-- 前置通知 --> <aop:before method="beforMethod" pointcut-ref="pointcut" /> <!-- 后置通知 --> <aop:after method="afterMethod" pointcut-ref="pointcut"/> <!-- 返回通知 --> <aop:after-returning method="afterReturnMethod" pointcut-ref="pointcut" returning="result"/> <!-- 异常通知 --> <aop:after-throwing method="afterThrowingMethod" pointcut-ref="pointcut" throwing="ex"/> <aop:around method="aroundMethod" pointcut-ref="pointcut"/> </aop:aspect> </aop:config> 类似这种引入到测试类里面，用的bean感觉是一样的（除非测试的时候自己又创建了一个上下文） 个人猜测，公司的环境太老了RunWith这种东西都没有，没验证过。
