Class ConnectionWrapper

java.lang.Object
com.gargoylesoftware.base.resource.jdbc.ConnectionWrapper
All Implemented Interfaces:
ManagedResource, AutoCloseable, Connection, Wrapper

public final class ConnectionWrapper extends Object implements Connection, ManagedResource
A wrapper for java.sql.Connection objects.

The contract with JDBC says that result sets must be closed before statements and statements must be closed before connections but java does not enforce this contract. It is quite possible to close a connection while statements and result sets are still open. While some database drivers handle this condition nicely, others will start failing in undefined ways when this happens.

This wrapper class is a solution to this problem. If the connection is only accessed through the wrapper then the wrapper will ensure that everything is closed in the correct order. It will also ensure that the various jdbc objects (connections, statements, result sets and metadata) cannot be used after they are closed.

This class was created for the JDBCResourceFactory but can be used by itself.

      public ConnectionWrapper(Connection connection)
      Create a new connection wrapper
      Parameters:
      connection - The connection that we are wrapping
  • Method Details

    • setResourceFactoryName

      public final void setResourceFactoryName(String name)
      Set the name of the factory that allocated this connection
      Specified by:
      setResourceFactoryName in interface ManagedResource
      Parameters:
      name - The name of the factory
    • setAutoCommit

      public void setAutoCommit(boolean autoCommit) throws SQLException
      Sets this connection's auto-commit mode. If a connection is in auto-commit mode, then all its SQL statements will be executed and committed as individual transactions. Otherwise, its SQL statements are grouped into transactions that are terminated by a call to either the method commit or the method rollback. By default, new connections are in auto-commit mode.

      The commit occurs when the statement completes or the next execute occurs, whichever comes first. In the case of statements returning a ResultSet, the statement completes when the last row of the ResultSet has been retrieved or the ResultSet has been closed. In advanced cases, a single statement may return multiple results as well as output parameter values. In these cases the commit occurs when all results and output parameter values have been retrieved.

      Specified by:
      setAutoCommit in interface Connection
      Parameters:
      autoCommit - true enables auto-commit; false disables auto-commit.
      Throws:
      SQLException - if a database access error occurs

    • createStatement

      public Statement createStatement() throws SQLException
      Creates a Statement object for sending SQL statements to the database. SQL statements without parameters are normally executed using Statement objects. If the same SQL statement is executed many times, it is more efficient to use a PreparedStatement object.

      Result sets created using the returned Statement object will by default have forward-only type and read-only concurrency.

      Specified by:
      createStatement in interface Connection
      Returns:
      a new Statement object
      Throws:
      SQLException - if a database access error occurs
    • prepareStatement

      public PreparedStatement prepareStatement(String sql) throws SQLException
      Creates a PreparedStatement object for sending parameterized SQL statements to the database. A SQL statement with or without IN parameters can be pre-compiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

      Note: This method is optimized for handling parametric SQL statements that benefit from precompilation. If the driver supports precompilation, the method prepareStatement will send the statement to the database for precompilation. Some drivers may not support precompilation. In this case, the statement may not be sent to the database until the PreparedStatement is executed. This has no direct effect on users; however, it does affect which method throws certain SQLExceptions.

      Result sets created using the returned PreparedStatement will have forward-only type and read-only concurrency, by default.

      Specified by:
      prepareStatement in interface Connection
      Parameters:
      sql - a SQL statement that may contain one or more '?' IN parameter placeholders
      Returns:
      a new PreparedStatement object containing the pre-compiled statement
      Throws:
      SQLException - if a database access error occurs
    • prepareCall

      public CallableStatement prepareCall(String sql) throws SQLException
      Creates a CallableStatement object for calling database stored procedures. The CallableStatement object provides methods for setting up its IN and OUT parameters, and methods for executing the call to a stored procedure.

      Note: This method is optimized for handling stored procedure call statements. Some drivers may send the call statement to the database when the method prepareCall is done; others may wait until the CallableStatement object is executed. This has no direct effect on users; however, it does affect which method throws certain SQLExceptions. Result sets created using the returned CallableStatement will have forward-only type and read-only concurrency, by default.

      Specified by:
      prepareCall in interface Connection
      Parameters:
      sql - a SQL statement that may contain one or more '?' parameter placeholders. Typically this statement is a JDBC function call escape string.
      Returns:
      a new CallableStatement object containing the pre-compiled SQL statement
      Throws:
      SQLException - if a database access error occurs
    • nativeSQL

      public String nativeSQL(String sql) throws SQLException
      Converts the given SQL statement into the system's native SQL grammar. A driver may convert the JDBC sql grammar into its system's native SQL grammar prior to sending it; this method returns the native form of the statement that the driver would have sent.
      Specified by:
      nativeSQL in interface Connection
      Parameters:
      sql - a SQL statement that may contain one or more '?' parameter placeholders
      Returns:
      the native form of this statement
      Throws:
      SQLException - if a database access error occurs
    • commit

      public void commit() throws SQLException

      Specified by:
      commit in interface Connection
      Throws:
      SQLException - if a database access error occurs
      See Also:
    • rollback

      public void rollback() throws SQLException
      Drops all changes made since the previous commit/rollback and releases any database locks currently held by this Connection. This method should be used only when auto- commit has been disabled.
      Specified by:
      rollback in interface Connection
      Throws:
      SQLException - if a database access error occurs
      See Also:
    • close

      public void close() throws SQLException
      Releases a Connection's database and JDBC resources immediately instead of waiting for them to be automatically released.

      Note: A Connection is automatically closed when it is garbage collected. Certain fatal errors also result in a closed Connection.

      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface Connection
      Throws:
      SQLException - if a database access error occurs

    • prepareStatement

      public PreparedStatement prepareStatement(String sql, int autoGeneratedKeys) throws SQLException
      Creates a default PreparedStatement object that has the capability to retrieve auto-generated keys. The given constant tells the driver whether it should make auto-generated keys available for retrieval. This parameter is ignored if the SQL statement is not an INSERT statement.

      Note: This method is optimized for handling parametric SQL statements that benefit from precompilation. If the driver supports precompilation, the method prepareStatement will send the statement to the database for precompilation. Some drivers may not support precompilation. In this case, the statement may not be sent to the database until the PreparedStatement object is executed. This has no direct effect on users; however, it does affect which methods throw certain SQLExceptions.

      Result sets created using the returned PreparedStatement object will by default be type TYPE_FORWARD_ONLY and have a concurrency level of CONCUR_READ_ONLY.

      Specified by:
      prepareStatement in interface Connection
      Parameters:
      sql - an SQL statement that may contain one or more '?' IN parameter placeholders
      autoGeneratedKeys - a flag indicating whether auto-generated keys should be returned; one of Statement.RETURN_GENERATED_KEYS or Statement.NO_GENERATED_KEYS
      Returns:
      a new PreparedStatement object, containing the pre-compiled SQL statement, that will have the capability of returning auto-generated keys
      Throws:
      SQLException - if a database access error occurs or the given parameter is not a Statement constant indicating whether auto-generated keys should be returned

    • prepareStatement

      public PreparedStatement prepareStatement(String sql, int[] columnIndexes) throws SQLException
      Creates a default PreparedStatement object capable of returning the auto-generated keys designated by the given array. This array contains the indexes of the columns in the target table that contain the auto-generated keys that should be made available. This array is ignored if the SQL statement is not an INSERT statement.

      An SQL statement with or without IN parameters can be pre-compiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

      Note: This method is optimized for handling parametric SQL statements that benefit from precompilation. If the driver supports precompilation, the method prepareStatement will send the statement to the database for precompilation. Some drivers may not support precompilation. In this case, the statement may not be sent to the database until the PreparedStatement object is executed. This has no direct effect on users; however, it does affect which methods throw certain SQLExceptions.

      Result sets created using the returned PreparedStatement object will by default be type TYPE_FORWARD_ONLY and have a concurrency level of CONCUR_READ_ONLY.

      prepareStatement in interface Connection
      Parameters:
      sql - an SQL statement that may contain one or more '?' IN parameter placeholders
      columnIndexes - an array of column indexes indicating the columns that should be returned from the inserted row or rows
      Returns:
      a new PreparedStatement object, containing the pre-compiled statement, that is capable of returning the auto-generated keys designated by the given array of column indexes
      Throws:
      SQLException - if a database access error occurs
      Since:
      1.4
    • prepareStatement

      public PreparedStatement prepareStatement(String sql, String[] columnNames) throws SQLException
      Creates a default PreparedStatement object capable of returning the auto-generated keys designated by the given array. This array contains the names of the columns in the target table that contain the auto-generated keys that should be returned. This array is ignored if the SQL statement is not an INSERT statement.

      An SQL statement with or without IN parameters can be pre-compiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

      Note: This method is optimized for handling parametric SQL statements that benefit from precompilation. If the driver supports precompilation, the method prepareStatement will send the statement to the database for precompilation. Some drivers may not support precompilation. In this case, the statement may not be sent to the database until the PreparedStatement object is executed. This has no direct effect on users; however, it does affect which methods throw certain SQLExceptions.

      Result sets created using the returned PreparedStatement object will by default be type TYPE_FORWARD_ONLY and have a concurrency level of CONCUR_READ_ONLY.

      Specified by:
      prepareStatement in interface Connection
