您需要将spring-instrument.jar代理包含为：

<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正常工作，您还需要添加一个Aspectjrt依赖项：

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

必须从Java代理开始才能使用InstrumentationLoadTimeWeaver。请参阅Spring文档
