在Spring LTW环境中使用Maven运行单元测试

Question

我正在使用Spring LoadTimeWeaving功能在ddd体系结构中开发应用程序。问题是我可以使用eclipse运行我的Junit测试，但不能通过Maven运行。我尝试了各种网站上提供的所有选项，但它根本无法正常工作。我收到以下例外情况：

原因：org.springframework.beans.factory.BeanCreationException：创建名为'loadTimeWeaver'的bean时出错：Bean初始化失败;嵌套异常是java.lang.IllegalStateException：ClassLoader [sun.misc.Launcher $ AppClassLoader]不提供'addTransformer（ClassFileTransformer）'方法。用Spring的代理指定一个定制的LoadTimeWeaver或启动你的Java虚拟机：-javaagent：org.springframework.instrument.jar

我已经将instrument jar作为argLine的一部分添加到surefire插件中。以下是我的代码工件。请让我知道我出错的地方或者是否有其他解决方案。

我使用Eclipse靛蓝发展，Maven的3.0 Mac OSX上

springContext.xml（其具有用于启用LTW功能的以下标签）

<context:load-time-weaver/> 

Answer 1

您需要包括一个spring-instrument.jar剂为：

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-surefire-plugin</artifactId> 
    <version>2.4</version> 
    <configuration> 
      <forkMode>once</forkMode> 
      <argLine> 
       -javaagent:"${settings.localRepository}/org/springframework/spring-instrument/${spring.framework.version}/spring-instrument-${spring.framework.version}.jar" 
     </argLine> 
      <useSystemClassloader>true</useSystemClassloader> 
    </configuration> 
</plugin> 

（替换$ {spring.framework.version}和$ {} settings.localRepository与你的价值观）

，当然还有一个AspecJ Maven插件为：

<plugin> 
    <groupId>org.codehaus.mojo</groupId> 
    <artifactId>aspectj-maven-plugin</artifactId> 
    <version>1.3</version> 
    <executions> 
     <execution> 
      <configuration> 
       <source>1.6</source> 
       <target>1.6</target> 
      </configuration>      
      <goals> 
       <goal>compile</goal>  <!-- use this goal to weave all your main classes --> 
       <goal>test-compile</goal> <!-- use this goal to weave all your test classes --> 
      </goals> 
     </execution> 
    </executions> 
</plugin> 

对于AspectJ的工作，你还需要增加一个aspectjrt依赖性：

<dependency> 
    <groupId>org.aspectj</groupId> 
    <artifactId>aspectjrt</artifactId> 
    <version>${aspectjrt.version}</version> 
</dependency> 

这里就介绍如何run AspectJ tests with Maven
