AspectJ load time weaving isn't work

Question

I want to configure my spring project to work with AspectJ load time weaving. I've done following:

1. added a <context:load-time-weaver aspectj-weaving="on"/> in my application contex
2. added aspectj in cache

3. added lines in my pom.xml

   <dependency>
       <groupId>org.springframework</groupId>
       <artifactId>spring-instrument</artifactId>
       <version>${springframework.version}</version>
   </dependency>
   
   <dependency>
       <groupId>org.springframework</groupId>
       <artifactId>spring-aspects</artifactId>
       <version>${springframework.version}</version>
   </dependency>
   
   <dependency>
       <groupId>org.aspectj</groupId>
       <artifactId>aspectjweaver</artifactId>
       <version>${org.aspectj.version}</version>
   </dependency>
   ...........
   
   <build>
       <plugins>
           <plugin>
               <groupId>org.apache.maven.plugins</groupId>
               <artifactId>maven-surefire-plugin</artifactId>
               <goals>
                   <project>test</project>
               </goals>
               <configuration>
                   <detail>true</detail>
                   <forkMode>once</forkMode>
                   <argLine>-javaagent:"${settings.localRepository}/org/springframework/spring-instrument/3.1.4.RELEASE/spring-instrument-3.1.4.RELEASE.jar"</argLine>
               </configuration>
           </plugin>
       </plugins>
   </build>
   

I have a test, and it fails.

@Cacheable(value = CacheConstants.FORM_TEMPLATE)
public int getRandomInt(){
    return new Random().nextInt();
}

@Test
public void test(){
    int i = getRandomInt();
    assertEquals(i, getRandomInt());
}

Can somebody explain why it fails? It obvious that load time weaving isn't work.

Thanks, M. Deinum! Your comment is very useful! I've rewrited my test as follows

DaoObject

interface DaoObject {
    int getCachedNumber();
}

DaoObjectImpl

@Repository
public class DaoObjectImpl implements DaoObject {
    @Cacheable(value = CacheConstants.FORM_TEMPLATE)
    public int getRandomInt(){
        return new Random().nextInt();
    }

    @Override
    public int getCachedNumber() {
        return getRandomInt();
    }
}

And my test now looks like

@Test
public void cacheTest(){
    assertEquals(daoObject.getCachedNumber(), daoObject.getCachedNumber());
}

All fine. Thanks!
