Java 为spring安全设置ldap查询超时

我正在使用带有LDAP身份验证的spring安全性。我的安全配置XML文件可以是。我的问题是查询在一段时间后超时。如何将超时设置为更大的值

以下是错误日志：

您应该扩展/实现所需的任何spring安全对象，并在创建上下文之前设置timeout环境变量：

env.put("com.sun.jndi.ldap.connect.timeout", LARGER_VALUE)
....
ctx = new InitialContext(env, null);

您可以在类路径上放置

jndi.properties

，并添加类似

com.sun.jndi.ldap.connect.timeout=
