Class SQLErrorCodesResolver

java.lang.Object

org.axonframework.eventsourcing.eventstore.legacyjpa.SQLErrorCodesResolver

All Implemented Interfaces:

PersistenceExceptionResolver

Deprecated.

in favor of using SQLErrorCodesResolver which moved to jakarta.

@Deprecated
public class SQLErrorCodesResolver
extends Object
implements PersistenceExceptionResolver

SQLErrorCodesResolver is an implementation of PersistenceExceptionResolver used to resolve sql error codes to see if it is an duplicate key constraint violation.

SQL Code configuration is available for the following database engines, which may be identifier automatically via the data source:

• HSQL DB
• MySQL
• Apache Derby
• DB2
• H2
• Informix Dynamic Server
• MS SQL Server
• Oracle
• PostgreSQL
• Sybase

This implementation will attempt to locate these error codes in the SQLException.getErrorCode() and SQLException.getSQLState(), respectively.

Since:

0.7

Constructor Detail

SQLErrorCodesResolver

public SQLErrorCodesResolver(List<Integer> duplicateKeyCodes)

Deprecated.

Initializes the SQLErrorCodesResolver using the given list of SQL Codes representing Key Constraint Violations.

Parameters:

duplicateKeyCodes - A list of Integer containing SQL Codes representing Key Constraint Violations

SQLErrorCodesResolver

public SQLErrorCodesResolver(DataSource dataSource)
                      throws SQLException

Deprecated.

Initialize a SQLErrorCodesResolver, automatically detecting the database name through the given dataSource. The database product name is used to resolve the database error codes.

Parameters:

dataSource - The data source providing the information about the backing database.

Throws:

SQLException - when retrieving the database product name fails

AxonConfigurationException - is the dataSource returns an unknown database product name. Use SQLErrorCodesResolver(Properties, DataSource) instead.

SQLErrorCodesResolver

public SQLErrorCodesResolver(String databaseProductName)

Deprecated.

Initialize a SQLErrorCodesResolver, automatically detecting the database name through the given dataSource. The database product name is used to resolve the database error codes. As an alternative you could set the property databaseDuplicateKeyCodes

Parameters:

databaseProductName - The product name of the database

Throws:

AxonConfigurationException - is the dataSource returns an unknown database product name. Use SQLErrorCodesResolver(Properties, String) instead.

SQLErrorCodesResolver

public SQLErrorCodesResolver(Properties properties,
                             String databaseProductName)

Deprecated.

Initialize a SQLErrorCodesResolver, automatically detecting the database name through the given dataSource. The database product name is used to resolve the database error codes. As an alternative you could set the property databaseDuplicateKeyCodes

The form of the properties is expected to be:
databaseName.duplicateKeyCodes=keyCode[,keyCode]*
Where databaseName is the database product name as returned by the driver, with spaces (' ') replaced by underscore ('_'). The key codes must be a comma separated list of SQL Error code numbers (int).

Parameters:

properties - the properties defining SQL Error Codes for Duplicate Key violations for different databases

databaseProductName - The product name of the database

SQLErrorCodesResolver

public SQLErrorCodesResolver(Properties properties,
                             DataSource dataSource)
                      throws SQLException

Deprecated.

Initialize the SQLErrorCodesResolver with the given properties and use the dataSource to automatically retrieve the database product name.

The form of the properties is expected to be:
databaseName.duplicateKeyCodes=keyCode[,keyCode]*
Where databaseName is the database product name as returned by the driver, with spaces (' ') replaced by underscore ('_'). The key codes must be a comma separated list of SQL Error code numbers (int).

Parameters:

properties - the properties defining SQL Error Codes for Duplicate Key violations for different databases

dataSource - The data source providing the database product name

Throws:

SQLException - when retrieving the database product name fails

Method Detail

isDuplicateKeyViolation

public boolean isDuplicateKeyViolation(Exception exception)

Deprecated.

Description copied from interface: PersistenceExceptionResolver

Indicates whether the given exception represents a duplicate key violation. Typically, duplicate key violations indicates concurrent access to an entity in the application. Two users might be accessing the same Aggregate, for example.

Specified by:

isDuplicateKeyViolation in interface PersistenceExceptionResolver

Parameters:

exception - The exception to evaluate

Returns:

true if the given exception represents a Duplicate Key Violation, false otherwise.

isDuplicateKeyCode

protected boolean isDuplicateKeyCode(SQLException sqlException,
                                     List<Integer> errorCodes)

Deprecated.

Parameters:

sqlException - The exception to locate the error code in

errorCodes - The error codes indicating duplicate key violations

Returns:

true if the error code of the sqlException is in the given list of errorCodes, otherwise false
