Your question

再ark容器里面创建两个web的biz包，其中一个发布服务，一个引用服务，然后再调用的时候提示《cant not find the corresponding JVM service. Please check if there is a SOFA deployment publish the corresponding JVM service》

There was an unexpected error (type=Internal Server Error, status=500). org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.IllegalStateException: JVM Reference[interface co demo.zip m.iteaj.service.TestService#] cant not find the corresponding JVM service. Please check if there is a SOFA deployment publish the corresponding JVM service. If this exception occurred when the application starts up, please add Require-Module to SOFA deployment's MANIFEST.MF to indicate the startup dependency of SOFA modules.

先咨询一下，使用jvm服务时业务代码里面的服务注册以及引用是否需要在spring的同一个ApplicationContext者父子关联的ApplicationContext

抱歉，才看到你的消息。 jvm 服务不要求引用和发布方的spring 上下文关系。

@iteaj 如果有比较急的问题，也可以单独给我发邮件 qilong.zql@antfin.com

@QilongZhang 你好，已经找到问题但不知道是否是正确的。每个biz包启动的时候框架都会为他们创建一个SofaRuntimeManager, 并且把他注册到SofaFramework里面，如下代码 ` @Bean @Role(BeanDefinition.ROLE_INFRASTRUCTURE) public static SofaRuntimeContext sofaRuntimeContext(@Value("${"

SofaBootInfraConstants.APP_NAME_KEY
"}") String appName, BindingConverterFactory bindingConverterFactory, BindingAdapterFactory bindingAdapterFactory) { ClientFactoryInternal clientFactoryInternal = new ClientFactoryImpl(); SofaRuntimeManager sofaRuntimeManager = new StandardSofaRuntimeManager(appName, SofaRuntimeAutoConfiguration.class.getClassLoader(), clientFactoryInternal); sofaRuntimeManager.getComponentManager().registerComponentClient( ReferenceClient.class, new ReferenceClientImpl(sofaRuntimeManager.getSofaRuntimeContext(), bindingConverterFactory, bindingAdapterFactory)); sofaRuntimeManager.getComponentManager().registerComponentClient( ServiceClient.class, new ServiceClientImpl(sofaRuntimeManager.getSofaRuntimeContext(), bindingConverterFactory, bindingAdapterFactory)); SofaFramework.registerSofaRuntimeManager(sofaRuntimeManager); return sofaRuntimeManager.getSofaRuntimeContext();

} 在获取服务引用的时候去获取对应注册的服务c：如下public ServiceProxy findServiceProxy(ClassLoader clientClassloader, Contract contract) { String interfaceType = contract.getInterfaceType().getCanonicalName(); String uniqueId = contract.getUniqueId(); for (SofaRuntimeManager sofaRuntimeManager : SofaFramework.getRuntimeSet()) { if (sofaRuntimeManager.getAppClassLoader().equals(clientClassloader)) { continue; } Biz biz = getBiz(sofaRuntimeManager); if (biz != null && biz.getBizState() == BizState.ACTIVATED) { ServiceComponent serviceComponent = findServiceComponent(uniqueId, interfaceType, sofaRuntimeManager.getComponentManager()); if (serviceComponent != null) { return new DynamicJvmServiceInvoker(clientClassloader, sofaRuntimeManager.getAppClassLoader(), serviceComponent.getService() .getTarget(), contract, biz.getIdentity()); } } } return null; }` 但由于runtime-sofa-boot-starter-plugin插件没有导出SofaFramework类，所以每个biz应用再加载这个类的时候不会委托给插件加载，而是每个biz包自己加载SofaFramework类，从而导致类SofaFramework并不是全局的，这样多个biz包注册的服务项目引用不到。解决方法：再插件里面导出SofaFramework类

@iteaj 你的分析是正确的，SOFABoot 代码重构的时候这部分应该是没有测试，我们会尽快修复~

@QilongZhang 快修复吧，这个demo很重要！

QilongZhang commented 5 years ago

@puzhi 好的，我今晚修复~ 多谢反馈

puzhi commented 5 years ago

@QilongZhang 为什么依然无法运行！是我什么地方没做对吗？我的环境

@puzhi 上面有链接的修复PR https://github.com/alipay/sofa-boot/pull/267 ，因为还没有合并，你可以把分支代码拉取下来本地安装。更新本地 jarslink 代码，运行 biz-jvm-invocation-sample 即可。
