java - BeanCreationException : Invocation of init method failed

Question

我正在尝试为我的 Spring 项目实现 LDAP 配置，但 LDAP 存储库未初始化。

错误跟踪是 -

以下是依赖关系-

我无法解决这个错误。 applicationContext.xml 中提到了 LDAP 存储库基础包，但仍然有扩展。请让我知道正确的实现。

来自 AbstractMethodError 的 JavaDoc:

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.

这意味着部署的 Spring 版本与您用于编译代码的版本不同。

确保部署的库与您的 IDE 中的库版本相同
