看点测试 - 不能让各方面bean的属性的权值

Question

看点

@Configurable 
@Aspect 
public class FilmCounter { 

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

    @Pointcut(
     "execution(* soundsystem.CompactDisc.play(int)) " + 
     "&& args(filmNumber)") 
    public void filmPlayed(int filmNumber) {} 

    @Before("filmPlayed(filmNumber)") 
    public void countFilm(int filmNumber){  
     int currentCount = getPlayCount(filmNumber); 
     filmCounts.put(filmNumber, currentCount + 1); 

     System.out.println("filmNumber " + filmNumber + " contains in ? " + filmCounts.containsKey(filmNumber) + " then filmCount = " + filmCounts.get(filmNumber)); 

    } 

    public int getPlayCount(int filmNumber){ 
     //System.out.println("filmNumber " + filmNumber + " contains in ? " + filmCounts.containsKey(filmNumber) + ""); 

     return filmCounts.containsKey(filmNumber) 
       ? filmCounts.get(filmNumber) : 0; 

    } 
} 

配置类

在AspectJ运行LIB所以不需要@EnableAspectJAutoProxy注释

@Configuration 
public class FilmCounterConfig { 

    @Bean 
    public CompactDisc filmDisk(){ 
     FilmDisc cd = new FilmDisc(); 
     cd.setTitle("1981's Melody Films"); 
     cd.setArtist("Kishor Kumar"); 
     List<String> films = new ArrayList<String>(); 
     films.add("Sanam Teri Kasam"); 
     films.add("Akhari Rasta"); 
     films.add("Hum Apke Hai Koun"); 
     films.add("Dil Hain Ke Manata Nahi"); 
     films.add("Hum Sath Sath Hain"); 
     cd.setFilms(films); 

     return cd; 
    } 

    @Bean 
    public FilmCounter filmCounter(){ 
     return new FilmCounter(); 
    } 
} 

测试类

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(classes=FilmCounterConfig.class) 
public class FilmCounterTest { 

    @Rule 
    public final SystemOutRule systemOutRule = new SystemOutRule().enableLog(); 

    @Autowired 
    private CompactDisc cd; 

    @Autowired 
    private FilmCounter counter; 

    @Test 
    public void testFilmCounter(){ 

     cd.play(1); System.out.println("counter.getPlayCount(1) = " + counter.getPlayCount(1)); 
     cd.play(2); 
     cd.play(3); 
     cd.play(3); 
     cd.play(3); 
     cd.play(3);  

     /*assertEquals(1, counter.getPlayCount(1)); 
     assertEquals(1, counter.getPlayCount(2)); 
     assertEquals(4, counter.getPlayCount(3)); 
     */ 

     System.out.println("Film 1 = " + counter.getPlayCount(1)); 
     System.out.println("Film 2 = " + counter.getPlayCount(2)); 
     System.out.println("Film 3 = " + counter.getPlayCount(3)); 

    } 

} 

当运行上面的测试情况下，我得到以下输出：

的图像显示控制台日志输出的第一个方法调用cd.play(2);看起来不错，但调用System.out.println("Film 1 = " + counter.getPlayCount(1));后它显示错误的结果（它应该显示“4”，但显示“0”）。

Answer 1

我想我知道发生了什么，看着你的控制台日志：有一个活动的方面实例记录你的方法调用，但可能与连接到你的测试中的不一样。这将解释方面日志输出与测试日志输出之间的差异。

如果您将System.out.println(this);添加到countFilm(int)建议和System.out.println(counter);到测试用例，我想您可能会看到两个不同的对象ID。

如果我是正确的，那么你的bean布线有问题。请在评论中提供反馈。
