```
public class SQLErrorCodesFactory
extends Object
```
Factory for creating SQLErrorCodes based on the "databaseProductName" taken from the DatabaseMetaData.
Returns SQLErrorCodes populated with vendor codes defined in a configuration file named "sql-error-codes.xml". Reads the default file in this package if not overridden by a file in the root of the class path (for example in the "/WEB-INF/classes" directory).

protected SQLErrorCodesFactory()
```
    Create a new instance of the SQLErrorCodesFactory class.
    Not public to enforce Singleton design pattern. Would be private except to allow testing via overriding the loadResource(String) method.
    Do not subclass in application code.

```
public static SQLErrorCodesFactory getInstance()
```
    Return the singleton instance.
  - loadResource
```
protected Resource loadResource(String path)
```
    Load the given resource from the class path.
    Not to be overridden by application developers, who should obtain instances of this class from the static getInstance() method.
    Protected for testability.
    参数:
    path - resource path; either a custom path or one of either SQL_ERROR_CODE_DEFAULT_PATH or SQL_ERROR_CODE_OVERRIDE_PATH.
    返回:
    the resource, or null if the resource wasn't found

public SQLErrorCodes getErrorCodes(String databaseName)
```
    Return the SQLErrorCodes instance for the given database.
    No need for a database meta-data lookup.
    参数:
    databaseName - the database name (must not be null)
    返回:
    the SQLErrorCodes instance for the given database
    抛出:
    IllegalArgumentException - if the supplied database name is null
  - getErrorCodes
```
public SQLErrorCodes getErrorCodes(DataSource dataSource)
```
    Return SQLErrorCodes for the given DataSource, evaluating "databaseProductName" from the DatabaseMetaData, or an empty error codes instance if no SQLErrorCodes were found.
    参数:
    dataSource - the DataSource identifying the database
    返回:
    the corresponding SQLErrorCodes object

```
    Associate the specified database name with the given DataSource.
    参数:
    dataSource - the DataSource identifying the database
    databaseName - the corresponding database name as stated in the error codes definition file (must not be null)
    返回:
    the corresponding SQLErrorCodes object (never null)
