java - 使用自定义 SSLSocketFactory 时出现 ClassNotFoundException

Question

我创建了一个自定义 SSLSocketFactory 类并将其设置如下

ldapEnv.put(Context.SECURITY_PROTOCOL, "ssl");
ldapEnv.put(FACTORY_SOCKET, socketFactoryClass);

LdapContext ldapContext = new InitialLdapContext(ldapEnv, null);

从 Eclipse Dev Environment 运行时工作正常，并从命令提示符将其作为 Jar 文件运行。但是当我将它包装在服务包装器中并将其作为 Windows 服务启动时，它不起作用。我得到以下异常，

javax.naming.CommunicationException: 192.168.100.22:636 [Root exception is java.lang.ClassNotFoundException: com/testing/diraccess/service/ActiveDirectory$TestSSLFactory]

有什么帮助吗？？？

似乎这个问题可能是由于 JNDI 依赖于设置正确的线程上下文类加载器(管理员可能没有这样做)，这是必需的，因为 JNDI 类由加载器层次结构和该类加载器基础上的类加载器加载将找不到应用程序/容器类加载器加载的类。因此 JNDI 提供了一个钩子(Hook)来通过线程上下文类加载器加载这些类。

看看这是否有效，

 // Save the current thread context class loader
 ClassLoader currentCL = Thread.currentThread().getContextClassLoader();

// Set the context class loader to the one we know for sure loaded classes inside configstore-core.jar
Thread.currentThread().setContextClassLoader(OmParticipant.class.getClassLoader());

// Invoke the jndi related code that will internally try to load our socket factory impl
...

//restore the original class loader
Thread.currentThread().setContextClassLoader(currentCL );
