scala是否会影响AspectJ / Spring AOP？在调用@Configurable时运行测试时遇到线程锁定问题

时间：2010-10-24 14:26:22

标签： spring scala locking aop aspectj

我有一个奇怪的问题，当我使用maven运行我的测试时，只要测试方法调用带有注释@Configurable的对象，它就会锁定。我可以使用AspectJ Weaver插件（显着地）在IDEA中运行测试，但是我不能用maven（无论是在IDEA还是在终端中执行它们）来执行它。

即使更奇怪，如果按ctrl-c，它也不会杀死进程。它只是在内存中保存了一个500meg的进程，直到我使用Ubuntu中的系统监视器杀死它。

在我将Scala添加到Java项目之前，这个问题从未发生过。注意，我没有编译Scala代码 - 只包括使用scala编译的jar，我将Scala编译器/库jar包括在类路径中。

基本上，Maven会运行一系列测试，然后挂起：

Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.206 sec
Running jobprep.domain.student.ActiveQuestionTests
Tests run: 26, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.065 sec
Running jobprep.domain.sysadmin.WebpageValidationTests
Tests run: 4, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.225 sec
Running jobprep.domain.question.openended.OpenEndedStudentSubmissionDeserializerTests

当谈到OpenEndedStudentSubmissionDeserializerTests时，它会冻结。似乎原因是OpenEndedStudentSubmissionDeserializer正在使用@Configurable。如果我注释掉测试类并再次运行测试，那么它将冻结下一个使用@Configurable的测试类。

编辑：这很有趣，如果我告诉maven在“jobprep.domain.question.openended”包中运行测试，它可以100％运行。如果我告诉它在“jobprep.domain”中运行所有内容，它仍然有效！如果我告诉它在“jobprep”中运行所有内容，那么就会出现问题。

对于这个root包，我是否应该注意Scala，AspectJ，Spring等？

在Maven中，如果我告诉surefire只加载我测试的一部分，它就可以了。我的测试套件中的1096个测试中有893个将运行和传递。这并不完美，因为我需要让剩下的测试仍然有效：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.6</version>
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.8.1</version>
        </dependency>
    </dependencies>
    <configuration>
        <includes>
            <include>**/dao/*Tests.java</include>
            <include>**/domain/*Tests.java</include>
            <include>**/domain/**/*Tests.java</include>
            <include>**/service/*Tests.java</include>
            <include>**/service/**/*Tests.java</include>
            <include>**/validator/*Tests.java</include>
        </includes>
        <excludes>
            <exclude>**/Abstract*Tests*.java</exclude>
            <exclude>**/DatabaseTests.java</exclude>
            <exclude>**/ControllerTests.java</exclude>
            <exclude>**/ValidationTests.java</exclude>
        </excludes>
        <skipTests>false</skipTests>
    </configuration>
</plugin>

很糟糕，我必须是这种细粒度，但我不知道有任何其他方法可以解决这个问题。

无论如何，一旦我添加了这一行，就会像以前一样开始锁定OpenEndedSubmissionDeserializerTests：

<include>**/controllers/*Tests.java</include>

你知道什么是好奇的吗？如果我只运行控制器 的测试，它就可以了！血淋淋的地狱！这是否意味着它们都是分开运行，而不是一起运行？！？

无论如何，当maven解冻时，如果我在linux中按CTRL-而不是CTRL-C，则会发生以下情况：

我可以得到一些帮助吗？我需要什么信息给你们？

我害怕构建这个项目并部署到服务器，即使所有测试都在IDE中运行...因为如果Aspects / AOP在测试中锁定，那么如果我要构建它可能不起作用并使用maven打包项目。

2 个答案:

答案 0 :(得分：2)

你的@Configurable类型是否扩展了Scala类？如果您可以发布示例代码（或理想情况下是一个简单的Maven项目），它显示了@Configurable类和Scala类的交互方式，这将有助于解决它。

答案 1 :(得分：0)

我的猜测是肯定的，aspectj正在干扰scala类。请注意，Scala有许多内部和外部类，而aspectj显然是not terribly bright about determining what the outer class is。

尝试添加

  <weaver>
    <exclude>scala..*</exclude>
  </weaver>

到你的aop.xml文件，看看会发生什么。
