With this example we are going to demonstrate how to get the JDBC Connection parameters. In short, to get the JDBC Connection parameters you should:
- Load the MySQL JDBC driver, using the
forName(String className)API method of the Class. - Get the Driver Instance. Invoke the
getDriver(String url)of the DriverManager, using the database URL. - Get available properties, using the
getPropertyInfo(String url, Properties info)of the Driver. It will return an array of DriverPropertyInfo objects describing possible properties. - For each one of the properties, get the name, value, description, choices and if property is required or not.
Let’s take a look at the code snippet that follows:
package com.javacodegeeks.snippets.core;
import java.sql.Driver;
import java.sql.DriverManager;
import java.sql.DriverPropertyInfo;
import java.sql.SQLException;
import java.util.Arrays;
public class ConnectionProperties {
public static void main(String[] args) {
try {
// Load the MySQL JDBC driver
String driverName = "com.mysql.jdbc.Driver";
Class.forName(driverName);
// Get the Driver instance
String serverName = "localhost";
String schema = "test";
String url = "jdbc:mysql://" + serverName + "/" + schema;
Driver driver = DriverManager.getDriver(url);
// Get available properties
DriverPropertyInfo[] properties = driver.getPropertyInfo(url, null);
for (int i=0; i < properties.length; i++) {
// Property information
String name = properties[i].name;
boolean required = properties[i].required;
String value = properties[i].value;
String description = properties[i].description;
String[] choices = properties[i].choices;
System.out.println("Property : " + name + "nRequired : " + required + "nValue : " + value + "nDescription : " + description + "nChoices : " + (choices!=null?Arrays.asList(choices):null) + "n");
}
} catch (ClassNotFoundException e) {
System.out.println("Could not find the database driver " + e.getMessage());
} catch (SQLException e) {
System.out.println("Could not retrieve database metadata " + e.getMessage());
}
}
}

If set to false, the driver will only communicate with the database when the requested transaction isolation is different than the whichever is newer, the last value that was set via Connection.setTransactionIsolation(), or the value that was read from the server when the connection was established. Note that useLocalSessionState=true will force the same behavior as alwaysSendSetIsolation=false, regardless of how alwaysSendSetIsolation is set.

If enabled the driver will throw an exception for a queries issued on a stale or dead connection, which belong to the current transaction, but will attempt reconnect before the next query issued on the connection in a new transaction. The use of this feature is not recommended, because it has side effects related to session state and data consistency when applications don't handle SQLExceptions properly, and is only designed to be used when you are unable to configure your application to handle SQLExceptions resulting from dead and stale connections properly. Alternatively, investigate setting the MySQL server variable "wait_timeout" to some high value rather than the default of 8 hours.

Description : Should the driver emulate java.sql.Blobs with locators? With this feature enabled, the driver will delay loading the actual Blob data until the one of the retrieval methods (getInputStream(), getBytes(), and so forth) on the blob data stream has been accessed. For this to work, you must use a column alias with the value of the column to the actual name of the Blob. The feature also has the following restrictions: The SELECT that created the result set must reference only one table, the table must have a primary key; the SELECT must alias the original blob column name, specified as a string, to an alternate name; the SELECT must cover all columns that make up the primary key.

Description : When enabled, query timeouts set via Statement.setQueryTimeout() use a shared java.util.Timer instance for scheduling.

High-load environments might want to consider disabling this functionality.

Required : false
Value : false
Description : Should the driver generate simplified parameter metadata for PreparedStatements when no metadata is available either because the server couldn't support preparing the statement, or server-side prepared statements are disabled?

This tends to work better than round-robin, as the randomness will somewhat account for spreading loads where requests vary in response time, while round-robin can sometimes lead to overloaded nodes if there are variations in response times across the workload. (2) "bestResponseTime" - the driver will route the request to the host that had the best response time for the previous transaction.

Required : false
Value : 50
Description : Number of queries to issue before falling back to master when failed over (when using multi-host failover). Whichever condition is met first, 'queriesBeforeRetryMaster' or 'secondsBeforeRetryMaster' will cause an attempt to be made to reconnect to the master. Defaults to 50.

Choices : null
Property : retainStatementAfterResultSetClose

Property : rewriteBatchedStatements
Required : false
Value : false
Description : Should the driver use multiqueries (irregardless of the setting of "allowMultiQueries") as well as rewriting of prepared statements for INSERT into multi-value inserts when executeBatch() is called? Notice that this has the potential for SQL injection if using plain java.sql.Statements and your code doesn't sanitize input correctly. Notice that for prepared statements, server-side prepared statements can not currently take advantage of this rewrite option, and that if you don't specify stream lengths when using PreparedStatement.set*Stream(), the driver won't be able to determine the optimum number of parameters per batch and you might receive an error from the driver that the resultant packet is too large. Statement.getGeneratedKeys() for these rewritten statements only works when the entire batch includes INSERT statements.

Property : useColumnNamesInFindColumn
Required : false
Value : false
Description : Prior to JDBC-4.0, the JDBC specification had a bug related to what could be given as a "column name" to ResultSet methods like findColumn(), or getters that took a String property. JDBC-4.0 clarified "column name" to mean the label, as given in an "AS" clause and returned by ResultSetMetaData.getColumnLabel(), and if no AS clause, the column name. Setting this property to "true" will give behavior that is congruent to JDBC-3.0 and earlier versions of the JDBC specification, but which because of the specification bug could give unexpected results. This property is preferred over "useOldAliasMetadataBehavior" unless you need the specific behavior that it provides with respect to ResultSetMetadata.
