JarCastingSpring App Base
Base set of tools and helpers originally designed for use within Spring MVC applications though not restricted to this use-case.
A Note on Dependencies
Spring App Base intentionally uses provided scope for most dependencies, the only transient dependency included is apache commons-lang as it's almost used everywhere.
This strategy allows you to control your dependencies. For example you may choose to use the spring MVC helpers but not wish to include spring-security.
For each component required dependencies will be listed which must be included at runtime.
JDBC Tools
SQL File Parser
JdbcHelper.getSql has overloaded methods to take an InputStream or path to return a string of the streams contents stripping SQL like comments
- Line comments
--are removed. - Block comments
/* */are removed.
Usage
// Import the static method getSql.
import static com.drunkendev.jdbc.JdbcHelper.getSql;
// Get SQL from a file on the filesystem.
// A path object overload is also available as of 1.1.
String sql = getSql("script.sql");
// A good use case is storing your SQL resources in the same packages as a
// service class.
String sql = getSql(App.class.getResourceAsStream("script.sql"));
ResultSetExtractor factories
JdbcHelper.singletonExtractor and JdbcHelper.singletonOptionalExtractor provide convenience methods for building new single record extractors from a given RowMapper. This can be used as follows.
private static final RowMapper<Customer> MAPPER_CUST = (rs, i)
-> new Customer(
rs.getLong("ID"),
rs.getString("NAME"),
rs.getString("EMAIL"));
private static final ResultSetExtractor<Customer> EXTRACTOR_CUST
= singletonExtractor(MAPPER_CUST);
