      Set the JDBC DataSource to obtain connections from.

    • getDataSource

      @Nullable public DataSource getDataSource()
      Return the DataSource used by this template.

    • obtainDataSource

      protected DataSource obtainDataSource()
      Obtain the DataSource for actual use.
      Returns:
      the DataSource (never null)

    • setDatabaseProductName

      public void setDatabaseProductName(String dbName)
      Specify the database product name for the DataSource that this accessor uses. This allows to initialize an SQLErrorCodeSQLExceptionTranslator without obtaining a Connection from the DataSource to get the meta-data.
      Parameters:
      dbName - the database product name that identifies the error codes entry
      See Also:

    • setExceptionTranslator

      public void setExceptionTranslator(SQLExceptionTranslator exceptionTranslator)
      Set the exception translator for this instance.

      If no custom translator is provided, a default SQLErrorCodeSQLExceptionTranslator is used which examines the SQLException's vendor-specific error code.

      See Also:

    • getExceptionTranslator

      public SQLExceptionTranslator getExceptionTranslator()
      Return the exception translator for this instance.

      Creates a default SQLErrorCodeSQLExceptionTranslator for the specified DataSource if none set, or a SQLStateSQLExceptionTranslator in case of no DataSource.

      See Also:

    • setLazyInit

      public void setLazyInit(boolean lazyInit)
      Set whether to lazily initialize the SQLExceptionTranslator for this accessor, on first encounter of an SQLException. Default is "true"; can be switched to "false" for initialization on startup.

      Early initialization just applies if afterPropertiesSet() is called.

      See Also:

    • isLazyInit

      public boolean isLazyInit()
      Return whether to lazily initialize the SQLExceptionTranslator for this accessor.
      See Also:

    • afterPropertiesSet

      public void afterPropertiesSet()
      Eagerly initialize the exception translator, if demanded, creating a default one for the specified DataSource if none set.
      Specified by:
      afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean
