JDBC resource opened but not safely closed

Reports JDBC resources that are not safely closed. JDBC resources reported by this inspection include java.sql.Connection, java.sql.Statement, java.sql.PreparedStatement, java.sql.CallableStatement, and java.sql.ResultSet.

By default, the inspection assumes that the resources can be closed by any method with 'close' or 'cleanup' in its name.


ResultSet findAllElements(Connection connection) throws SQLException { PreparedStatement statement = connection.prepareStatement("SELECT * FROM TABLE");//statement is not closed statement.execute(); return statement.getResultSet(); }

Use the following options to configure the inspection:

  • Whether a JDBC resource is allowed to be opened inside a try block. This style is less desirable because it is more verbose than opening a resource in front of a try block.

  • Whether the resource can be closed by any method call with the resource passed as argument.
