我正在将我的spring项目从版本4.3.23升级到版本5.2.13
我在项目的ldap.xml文件中有以下代码，在4.3.23中运行良好，但在5.2.13中出错：
<bean id="contextSourceReadTarget" class="org.springframework.ldap.core.support.LdapContextSource">
<property name="urls" value="ldap://localhost:12345" />
<property name="base" value="dc=memorynotfound,dc=com" />
<property name="userDn" value="uid=admin" />
<property name="password" value="secret" />
<property name="dirObjectFactory"
value="org.springframework.ldap.core.support.DefaultDirObjectFactory" />
<property name="pooled" value="false" />
<property name="referral" value="follow" />
</bean>但是当我运行代码时 java.lang.NoClassDefFoundError: org/springframework/core/JdkVersion 在搜索之后，我发现jdkversion在Spring5.x中被删除了
我想知道如何修复我的代码，使之在Spring5.x上正常工作。
以下是错误的完整堆栈跟踪：

我假设您没有使用springboot，我们讨论的是“纯spring”应用程序。
很明显，spring框架中试图使用丢失类的代码属于spring4生态系统（否则任何依赖spring5并使用ldap集成的应用程序都会失败，spring团队也会在这方面有一个主要的bug）
假设没有重大的bug，那么应用程序的类路径中肯定有一些spring4jar
所以我建议做以下几点：
检查类路径。因为我假设，你正在编译一个war-用winrar或者别的什么打开工件，看看它的内容
WEB-INF/lib文件夹。如果你看到了属于Spring4的东西-修复你的pom.xml具有正确的依赖关系。如果你编译ear-它可能有许多模块需要检查，但基本上过程是相同的，我相信你已经明白了要点weblogic在某些共享文件夹中可能有一些“共享”jar（包括spring）。我对这个应用服务器不是很熟悉，但这些jar很可能属于spring4生态系统，它们可能在运行时“找到”应用程序的类路径。Maven显然不会表现出来。

您应该一起更新所有spring依赖项（在本例中是springldap），检查是否所有spring依赖项都更新到spring5，因为spring是一个非常模块化的框架，所以定义一个关于其模块版本管理的变量总是很有帮助的
