每次从Ldap连接池返回新连接时

我已经在我的项目中实现了LDAP连接池，并注意到一个奇怪的行为，每次新连接请求到来时，我配置的LDAP连接池都返回新连接，而不是重新使用返回池的现有连接。

LDAP JNDI日志 ：

我的连接设置：

  Hashtable env = new Hashtable(); env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory"); env.put(Context.PROVIDER_URL, "ldaps://" + server + ":" + serverPort); env.put(Context.SECURITY_AUTHENTICATION, "simple"); env.put(Context.SECURITY_PRINCIPAL, pUserName); env.put(Context.SECURITY_CREDENTIALS, pPassword); env.put(LdapContext.CONTROL_FACTORIES, "com.sun.jndi.ldap.ControlFactory"); env.put(Context.SECURITY_PROTOCOL, "ssl"); env.put("com.sun.jndi.ldap.read.timeout", "300000"); Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider()); // load the location of keystore that holds trusted root certificates from web.xml ServletContext context = ApplicationServlet.getApplication().getServlet().getServletContext(); String certificatePath = context.getInitParameter("AD_CERTIFICATE_PATH"); System.setProperty("javax.net.ssl.trustStore", certificatePath); // System.setProperty("javax.net.debug", "all"); // For connection pooling env.put("com.sun.jndi.ldap.connect.pool", "true"); System.setProperty("com.sun.jndi.ldap.connect.pool.protocol", "plain ssl"); System.setProperty("com.sun.jndi.ldap.connect.pool.maxsize", poolMaxSize); System.setProperty("com.sun.jndi.ldap.connect.pool.prefsize", poolPrefSize); System.setProperty("com.sun.jndi.ldap.connect.pool.timeout", poolTimeOut); System.setProperty("com.sun.jndi.ldap.connect.pool.debug", "fine"); ctx = new InitialDirContext(env); return (DirContext) ctx; 

感谢您确定根本原因在哪里，为什么每次创建新连接而不是重用。

您尚未实现任何连接池，您正在使用来自Sun的损坏的DirContext连接池。 这是不鼓励的。 看一下Spring LDAP的ContextSource池。 它工作得很好。
