spring - 在 Spring LTW 环境中使用 Maven 运行单元测试

标签 spring junit4 maven-surefire-plugin load-time-weaving

我正在使用 Spring LoadTimeWeaving 功能在 ddd 架构中开发应用程序。问题是我可以使用 Eclipse 但不能通过 Maven 运行我的 Junit 测试。我已经尝试了各种网站上给出的所有选项，但它根本不起作用。我收到以下异常:

引起: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。指定自定义 LoadTimeWeaver 或使用 Spring 的代理启动 Java 虚拟机:-javaagent:org.springframework.instrument.jar

我已将仪器 jar 作为 argLine 的一部分添加到 surefire 插件中。以下是我的代码工件。请让我知道我哪里出错了或者是否有任何其他解决方案。

我在 Mac OSX 上使用 Eclipse Indigo 进行开发，Maven 3.0

springContext.xml(它具有以下用于启用LTW功能的标签)
<context:load-time-weaver/>

最佳答案

你需要包含一个 spring-instrument.jar代理为:

<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>

(用您的值替换 ${spring.framework.version} 和 ${settings.localRepository} )

当然还有一个 AspecJ Maven 插件:
<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>

要使 AspectJ 工作，您还需要添加 aspectjrt依赖:
<dependency>
  <groupId>org.aspectj</groupId>
  <artifactId>aspectjrt</artifactId>
  <version>${aspectjrt.version}</version>
</dependency>
