Class SQLExceptionSubclassTranslator

java.lang.Object

org.springframework.jdbc.support.AbstractFallbackSQLExceptionTranslator

org.springframework.jdbc.support.SQLExceptionSubclassTranslator

All Implemented Interfaces:

SQLExceptionTranslator

public class SQLExceptionSubclassTranslator
extends AbstractFallbackSQLExceptionTranslator

SQLExceptionTranslator implementation which analyzes the specific SQLException subclass thrown by the JDBC driver.

Falls back to a standard SQLStateSQLExceptionTranslator if the JDBC driver does not actually expose JDBC 4 compliant SQLException subclasses.

This translator serves as the default JDBC exception translator as of 6.0. As of 6.2.12, it specifically introspects BatchUpdateException to look at the underlying exception, analogous to the former default SQLErrorCodeSQLExceptionTranslator.

Since:

2.5
