Class CommonsDbcpNativeJdbcExtractor

java.lang.Object

com.im.commons.db.util.CommonsDbcpNativeJdbcExtractor

public class CommonsDbcpNativeJdbcExtractor
extends java.lang.Object

Partial (only the functionality we use) copy of CommonsDbcpNativeJdbcExtractor from Spring 4.3.9.

Added while migrating to Spring 5.2.5. The class CommonsDbcpNativeJdbcExtractor was removed from spring and was not possible to use the suggested replacements/workarounds.

The class contains also some methods copied from other spring 4.3.9 classes, also not available anymore:

• getNativeConnection(java.sql.Connection) from NativeJdbcAdapter
• invokeJdbcMethod(java.lang.reflect.Method, java.lang.Object) from ReflectionUtils
• invokeJdbcMethod(java.lang.reflect.Method, java.lang.Object, java.lang.Object...) from ReflectionUtils

Implementation of the NativeJdbcExtractor interface for the Apache Commons DBCP connection pool, version 1.1 or higher.

Returns the underlying native Connection, Statement, etc to application code instead of DBCP's wrapper implementations. The returned JDBC classes can then safely be cast, e.g. to oracle.jdbc.OracleConnection.

This NativeJdbcExtractor can be set just to allow working with a Commons DBCP DataSource: If a given object is not a Commons DBCP wrapper, it will be returned as-is.

Note that this version of CommonsDbcpNativeJdbcExtractor will work against the original Commons DBCP in org.apache.commons.dbcp as well as against Tomcat 5.5's relocated Commons DBCP version in the org.apache.tomcat.dbcp.dbcp package.

Method Detail

getNativeConnection

public java.sql.Connection getNativeConnection(java.sql.Connection con)
                                        throws java.sql.SQLException

Method copied from NativeJdbcAdapter from spring 4.3.9 (removed in Spring 5.2.5).

Check for a ConnectionProxy chain, then delegate to doGetNativeConnection.

ConnectionProxy is used by Spring's TransactionAwareDataSourceProxy and LazyConnectionDataSourceProxy. The target connection behind it is typically one from a local connection pool, to be unwrapped by the doGetNativeConnection implementation of a concrete subclass.

Parameters:

con -

Returns:

native connection

Throws:

java.sql.SQLException

getNativePreparedStatement

public java.sql.PreparedStatement getNativePreparedStatement(java.sql.PreparedStatement ps)
                                                      throws java.sql.SQLException

Throws:
