• setSeparator

  public void setSeparator​(String separator)

  public void setContinueOnError​(boolean continueOnError)

  Flag to indicate that all failures in SQL should be logged but not cause a failure.

  Defaults to false.

  参数:

  continueOnError - true if script execution should continue on error

• setIgnoreFailedDrops

  public void setIgnoreFailedDrops​(boolean ignoreFailedDrops)

  Flag to indicate that a failed SQL DROP statement can be ignored.

  This is useful for a non-embedded database whose SQL dialect does not support an IF EXISTS clause in a DROP statement.

  The default is false so that if the populator runs accidentally, it will fail fast if a script starts with a DROP statement.

  参数:

  ignoreFailedDrops - true if failed drop statements should be ignored

• populate

  public void populate​(Connection connection)
                throws ScriptException

  Populate, initialize, or clean up the database using the provided JDBC connection.

  Concrete implementations may throw an SQLException if an error is encountered but are strongly encouraged to throw a specific ScriptException instead. For example, Spring's ResourceDatabasePopulator and DatabasePopulatorUtils wrap all SQLExceptions in ScriptExceptions.

  指定者:

  populate 在接口中 DatabasePopulator

  参数:

  connection - the JDBC connection to use to populate the db; already configured and ready to use; never null

  抛出:

  ScriptException - in all other error cases

• execute

  public void execute​(DataSource dataSource)
               throws ScriptException

  Execute this ResourceDatabasePopulator against the given DataSource.
