在Spring LTW環境中使用Maven運行單元測試

Question

我正在使用Spring LoadTimeWeaving功能在ddd體系結構中開發應用程序。問題是我可以使用eclipse運行我的Junit測試，但不能通過Maven運行。我嘗試了各種網站上提供的所有選項，但它根本無法正常工作。我收到以下例外情況：

原因：org.springframework.beans.factory.BeanCreationException：創建名爲'loadTimeWeaver'的bean時出錯：Bean初始化失敗;嵌套異常是java.lang.IllegalStateException：ClassLoader [sun.misc.Launcher $ AppClassLoader]不提供'addTransformer（ClassFileTransformer）'方法。用Spring的代理指定一個定製的LoadTimeWeaver或啓動你的Java虛擬機：-javaagent：org.springframework.instrument.jar

我已經將instrument jar作爲argLine的一部分添加到surefire插件中。以下是我的代碼工件。請讓我知道我出錯的地方或者是否有其他解決方案。

我使用Eclipse靛藍髮展，Maven的3.0 Mac OSX上

springContext.xml（其具有用於啓用LTW功能的以下標籤）

<context:load-time-weaver/> 

Answer 1

您需要包括一個spring-instrument.jar劑爲：

<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> 

（替換$ {spring.framework.version}和$ {} settings.localRepository與你的價值觀）

，當然還有一個AspecJ Maven插件爲：

<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> 

對於AspectJ的工作，你還需要增加一個aspectjrt依賴性：

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

這裏就介紹如何run AspectJ tests with Maven
