Java 尝试将IBM Notes数据迁移到Graph db中
我正在使用OpenNTF Domino API开发一个XPages应用程序,以探索图形数据建模功能。我以IBMDomino附带的Teamroom为例 我已经定义了一种将响应文档迁移到Grap db的方法,但是我得到了错误消息:无法对非静态方法进行静态引用 下面是该方法的外观:Java 尝试将IBM Notes数据迁移到Graph db中,java,xpages,Java,Xpages,我正在使用OpenNTF Domino API开发一个XPages应用程序,以探索图形数据建模功能。我以IBMDomino附带的Teamroom为例 我已经定义了一种将响应文档迁移到Grap db的方法,但是我得到了错误消息:无法对非静态方法进行静态引用 下面是该方法的外观: private void migrateResponses(DFramedTransactionalGraph<DGraph> profilesGraph) { try { Databa

你有没有建议我应该如何调整代码使其工作?除非OpenNTF或TinkerPop正在对提供的注释进行某种处理,否则你正在尝试调用接口上的非静态方法。您确定不想更改:
Post.addResponse(vertexResponse);
到

尝试将
Post
更改为Post
。看起来您指的是类而不是对象。请尝试将Post
更改为Post
。看起来您指的是类而不是对象。是的,这是正确的。对实例而不是接口调用方法。那就行了。是的,这是正确的。对实例而不是接口调用方法。那就行了。
