我的简化代码(表明连接中断错误“IO错误:套接字读取超时”):
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
this.connection = DriverManager.getConnection("jdbc:oracle:thin:@", properties);
while(isStarted){
this.statement = this.connection.createStatement();
ResultSet result = this.statement.executeQuery("select sysdate from dual");
result.next();
System.out.println("Sysdate: " + result.getString(1));
result.close();
this.statement.close();
this.statement = null;
TimeUnit.SECONDS.sleep(4);
}
this.connection.close();
this.connection = null;
我赶了4-5个小时后:
IO Error: Socket read timed out
java.sql.SQLRecoverableException: IO Error: Socket read timed out
at oracle.jdbc.driver.T4CStatement.executeForDescribe(T4CStatement.java:886)

at oracle.jdbc.driver.OracleStatement.executeQuery(OracleStatement.java:1491)
at oracle.jdbc.driver.OracleStatementWrapper.executeQuery(OracleStatementWrapper.java:406)
原因是什么?如何解决这个问题?

我遇到了同样的问题。检查您的服务,并确保只有OracleServiceXE和Oracle XETNSListener正在运行。
您可以使用命令
在cmd中对其进行交叉检查netstat -ano |找到" 1521"
在结果中,最后一列显示PID,它应该是唯一的。如果该命令未返回任何结果,则表示您的监听器未运行。
