Interface ConnectionProvider

All Known Implementing Classes:

DataSourceConnectionProvider

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ConnectionProvider

Provides Connections to FluentJdbc Queries. It allows both acquiring and releasing a Connection. This makes it possible to integrate FluentJdbc to most pooling / transaction management solutions.

Implementation pattern

 query -> {
     Connection connection = ... // acquire a connection 
     query.receive(connection)   // make the connection available to FluentJdbc queries
     connection.close()          // release connection - may not be needed if connection is already managed
 }         
 

Example implementations:

Getting connection from a datasource (provided in the library as DataSourceConnectionProvider):

 query -> {
      try(Connection connection = dataSource.getConnection()) {
          query.receive(connection);
      }
   }
 

Getting connection from a callback mechanism (eg Spring JdbcOperations/JdbcTemplate):

 query -> {
     jdbcTemplate.execute(connection -> {
        query.receive(connection);
     });
 }
