java - 每次从 Ldap 连接池返回新的 Connection

我在我的项目中实现了 LDAP 连接池,并注意到一个奇怪的行为,即每次新的连接请求到来时,我配置的 LDAP 连接池都会返回新连接,而不是重新使用返回到池中的现有连接。

LDAP JNDI 日志:

我的连接设置:

    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;

感谢您确定根本原因在哪里,为什么每次都创建新连接而不是重用。

最佳答案

您还没有实现任何连接池,您正在使用来自 Sun 的损坏的 DirContext 连接池。这是气馁。查看 Spring LDAP 的 ContextSource 池。效果很好。

关于java - 每次从 Ldap 连接池返回新的 Connection,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/27057672/
