每次從Ldap連接池返回新連接

我在我的項目中實現了LDAP連接池，並注意到一個奇怪的行爲，每當新的連接請求到來時，我配置的LDAP連接池都將返回新連接，而不是重新使用現有連接返回到池。每次從Ldap連接池返回新連接

我的連接設置：在確定

Hashtable<String, String> env = new Hashtable<String, String>(); 

    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;

由於這裏是根本原因，爲什麼每次新的連接被創建，而不是重複使用。

顯然您的游泳池超時已到期。注意你不需要添加SSL提供商十年。 – EJP 2014-11-21 09:28:33

Connection Timeout設置爲5分鐘，並且每個日誌連接立即過期。 – 2014-11-21 09:37:47

由於超時屬性設置爲5分鐘，理想情況下，空閒連接應在到期前等待5分鐘。 – 2014-11-21 09:39:20

您尚未實施任何連接池，您正在使用來自Sun的中斷DirContext連接池。這是不鼓勵的。看看Spring LDAP的ContextSource池。它工作得很好。

下定決心。他或者正在使用SuN連接池，或者他沒有使用任何連接池。 Sun JNDI連接池適用於我， – EJP 2014-11-21 09:50:09

我們正在使用Sun JNDI連接池... – 2014-11-21 12:43:40

而且'這被勸阻'了誰？ – EJP 2014-11-21 23:33:54
