我试图通过连接到eclipse IDE中的Oracle数据库来使用我的JDBC程序启用日志。为JDBC启用日志记录
我已经通过这个SO发布JDBC logging to file 然后我创建了下面的java程序并从我的eclipse IDE运行它，但我无法看到由JDBC驱动程序类生成的任何日志。
import java.io.File;
import java.io.FileInputStream;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.Properties;
import java.util.logging.LogManager;
import java.util.logging.Logger;
public class Logging {
static Logger log = Logger.getLogger(Logging.class.toString());
static Connection con = null;
public static void main(String[] args) throws SQLException,
ClassNotFoundException {
System.setProperty("oracle.jdbc.Trace", Boolean.TRUE.toString());
System.setProperty("java.util.logging.config.file",
"OracleLog.properties");
log.info("Test Message");
enableLogging(false);
getConnection();
closeConnection();
}
static private void enableLogging(boolean logDriver) {
try {
oracle.jdbc.driver.OracleLog.setTrace(true);
// compute the ObjectName
String loader = Thread.currentThread().getContextClassLoader()
.toString().replaceAll("[,=:\"]+", "");
javax.management.ObjectName name = new javax.management.ObjectName(
"com.oracle.jdbc:type=diagnosability,name=" + loader);
// get the MBean server
javax.management.MBeanServer mbs = java.lang.management.ManagementFactory
.getPlatformMBeanServer();
// find out if logging is enabled or not
System.out.println("LoggingEnabled = "
+ mbs.getAttribute(name, "LoggingEnabled"));
// enable logging
mbs.setAttribute(name, new javax.management.Attribute(
"LoggingEnabled", true));
File propFile = new File("path/to/properties");
LogManager logManager = LogManager.getLogManager();
logManager.readConfiguration(new FileInputStream(propFile));
if (logDriver) {
DriverManager.setLogWriter(new PrintWriter(System.err));
}
} catch (Exception e) {
e.printStackTrace();
}
}
public static Connection getConnection() throws SQLException,
ClassNotFoundException {
Properties connectionProps = new Properties();
connectionProps.put("user", "test_app");
connectionProps.put("password", "test");
Class.forName("oracle.jdbc.driver.OracleDriver");
con = DriverManager.getConnection(
"jdbc:oracle:thin:@"+HOST_IP+":1521:"+SID,
connectionProps);
System.out.println("Connected to database");
return con;
}
public static void closeConnection() throws SQLException {
if (con != null) {
con.close();
}
}
}
，我有以下我OracleLog.properties内容文件：
INFO: Test Message
javax.management.InstanceNotFoundException: com.oracle.jdbc:type=diagnosability,[email protected]

oracle.jdbc.level=INFO
oracle.jdbc.handlers=java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level=INFO
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter
但是，当我放置在ojdbc6-11.2.0.3.jar然后classpath中我得到异常的运行我的程序
如果我在类路径中有ojdbc6_g.jar，那么我也会得到相同的异常。
请让我知道如何为我的JDBC程序启用日志记录？基本上我期待看到由内部JDBC代码生成的日志。
更新： 现在我把ojdbc6dms.jar文件中的classpath，我的计划是给下面的例外：

你有没有正确的驱动程序在classpath中？ '确保调试JAR文件（例如ojdbc5_g.jar或ojdbc6_g.jar）是CLASSPATH环境变量中唯一的Oracle JDBC JAR文件。'和'为了获得日志输出，你必须使用调试JAR文件，这些文件在文件名' – 2014-11-21 11:51:10
@ KonstantinV.Salikhov'中用'_g'表示，现在我已经尝试在类路径中使用'ojdbc6_g.jar'，但是得到了相同的错误消息，我已更新我的问题与错误的详细信息。 – user3181365 2014-11-21 11:59:04
mbean使用不同的名称进行注册，请尝试使用jconsole并查看mbean名称并使用正确的名称。 – 2014-11-21 12:02:57
