[使用CXF JAX-RS的Liferay 7.1定制portlet

问题描述 投票：3回答：1

我的捆绑包尝试启动时出现以下错误：

The activate method has thrown an exception
java.lang.NoClassDefFoundError: Could not initialize class javax.ws.rs.core.EntityTag

[当我尝试部署OSGi模块时发生。

我正在使用：

  • Liferay 7.1.2-ga3
  • “ org.apache.cxf：cxf-rt-rs-client：3.2.5”
  • “ javax.ws.rs:javax.ws.rs-api:2.1”

我仍然不明白为什么OSGi容器会引发该错误，但是一种解决方法是可以通过在相关的OSGI模块中添加以下内容来尝试推迟模块初始化：

 @Reference(target = ModuleServiceLifecycle.PORTAL_INITIALIZED, unbind = "-") 
protected void setModuleServiceLifecycle(ModuleServiceLifecycle moduleServiceLifecycle) { }

对我来说很好。希望对您有所帮助！
