以下是依赖 –
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.
请告诉我正确的说明.

最佳答案 从JavaDoc for AbstractMethodError：
Thrown when an application tries to call an abstract method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of some class has incompatibly changed since the currently executing method was last compiled.
这意味着Spring的部署版本与您用于编译代码的版本不同.
确保已部署的库与IDE中的库版本相同
