java如何使用jndi设置连接超时？

Question

我有这个密码：

Object objc = null;

if (jdbcFactory == null) {
  try {
    InitialContext c = new InitialContext();
    this.jdbcFactory = (DataSource) c.lookup(this.jndiName);

  }
  catch (Exception e) {
    Logger log = Logger.getLogger(this.getClass());

  }
}
// jdbcFactory initiated.
try {
  objc = this.jdbcFactory.getConnection();  
} catch (Exception e) {

}
return objc;
}

如何设置连接超时？（不使用context.xml）

Answer 1

根据您的代码，您正在将this.jdbcFactory转换为javax.sql.DataSource；根据代码，这个接口扩展了javax.sql.CommonDataSource，它定义了以下方法javax.sql.CommonDataSource#setLoginTimeout

本方法文件规定：

 * <p>Sets the maximum time in seconds that this data source will wait
 * while attempting to connect to a database.  A value of zero
 * specifies that the timeout is the default system timeout
 * if there is one; otherwise, it specifies that there is no timeout.
 * When a <code>DataSource</code> object is created, the login timeout is
 * initially zero.
