Question

我正在尝试为我的Spring Project实现LDAP配置，但LDAP Repository未初始化。

错误跟踪是 -

以下是依赖项 -

我无法解决此错误。在applicationContext.xml中提到了LDAP存储库基础包，但仍然遵循以下内容。请告诉我正确的意见。

来自AbstractMethodError的JavaDoc：

当应用程序尝试调用抽象方法时抛出。通常，编译器会捕获此错误;如果自上次编译当前正在执行的方法以来某些类的定义发生了不兼容的更改，则此错误只能在运行时发生。

这意味着Spring的部署版本与您用于编译代码的版本不同。

确保部署的库与IDE中的库版本相同
