我正在使用最近的 springboot v1.5.2 和 aspectj(v1.8.10)的加载时间编织。在外部 tomcat 上运行我的应用程序时,我能够将 spring bean 注入到我的 aspectj 方面,现在我想知道为什么嵌入式 tomcat 也失败了?
弹簧靴:1.5.2
方面:1.8.10
弹簧仪表:4.3.7.RELEASE
maven 命令:mvn spring-boot:run -Drun.jvmArguments="-javaagent:aspectjweaver-1.8.10.jar -javaagent:spring-instrument-4.3.7.RELEASE.jar -Dserver.port=8080 -Dserver.contextPath= /自定义应用程序”
方面配置:
@Configuration
@EnableLoadTimeWeaving
@EnableAspectJAutoProxy(proxyTargetClass = true)
public class AspectConfig {
@Bean
public RuntimeContainerDelegateAspect runtimeContainerDelegateAspect() {
return Aspects.aspectOf(RuntimeContainerDelegateAspect.class);
}}
方面:
@Aspect
public class RuntimeContainerDelegateAspect {
private static final Logger LOGGER = LoggerFactory.getLogger(RuntimeContainerDelegateAspect.class);
@Autowired
private RestApplicationDeployer deployer;
@Pointcut("execution(* org.someapp.container.impl.RuntimeContainerDelegateImpl.deployApplication(..))")
public void deployApplication() {
}
@Pointcut("execution(* org.someapp.container.impl.RuntimeContainerDelegateImpl.undeployProcessApplication(..))")
public void undeployApplication() {
}
@Around("deployApplication()")
public void aroundDeploy(ProceedingJoinPoint pjp) throws Throwable {
if (LOGGER.isInfoEnabled())
LOGGER.info("RuntimeDelegateCalled: " + pjp.toString());
AbstractProcessApplication app = (AbstractProcessApplication) pjp.getArgs()[0];
LOGGER.debug("deployer={}", deployer);
deployer.deploy(app);
}
@Around("undeployApplication()")
public void aroundUndeploy(ProceedingJoinPoint pjp) throws Throwable {
if (LOGGER.isInfoEnabled())
LOGGER.info("RuntimeDelegateCalled: " + pjp.toString() + "\n" +
"Default implementation does nothing.");
}
}
部署者:
@Component
public class RestApplicationDeployer {
//it's just an ordinary spring bean
}
实际结果:deployer = null,因为 aspectj 创建了 RuntimeContainerDelegateAspect 的新实例来处理 @Around 通知
预期结果:deployer = spring bean RestApplicationDeployer
PS:这在外部 tomcat 实例上完美运行
