Running Unit Tests using Maven in Spring LTW Environment

问题

I am developing an application in a ddd architecture using Spring LoadTimeWeaving feature. The problem is i can run my Junit tests using eclipse but not through Maven. I have tried all the options given on various sites but it simply isn't working. I get the following exception:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loadTimeWeaver': Initialization of bean failed; nested exception is java.lang.IllegalStateException: ClassLoader [sun.misc.Launcher$AppClassLoader] does NOT provide an 'addTransformer(ClassFileTransformer)' method. Specify a custom LoadTimeWeaver or start your Java virtual machine with Spring's agent: -javaagent:org.springframework.instrument.jar

I have added the instrument jar as a part of argLine to surefire plugin. Following are my code artifacts. Please let me know where i am going wrong or if there is any other solution.

I am using Eclipse Indigo for Development, Maven 3.0 on Mac OSX

springContext.xml (Its has the following tag for enabling LTW feature)

<context:load-time-weaver/>

回答1:

you need to include a spring-instrument.jar agent as:

<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>

( replace ${spring.framework.version} and ${settings.localRepository} with your values )

and of course an AspecJ Maven plugin as:

<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>

For AspectJ to work, you would also need to add an aspectjrt dependency:

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

Here a full example on how to run AspectJ tests with Maven
