Testing. 1. Overview. Spring JdbcTemplate is a powerful tool for developers to focus on writing SQL queries and extracting results. It connects to the back-end database and executes SQL queries directly. Therefore, we can use integration tests to make sure that we can pull data from the database properly. Also, we can write unit tests to check In Spring 3.x you should use JdbcTemplate. In previous versions of Spring SimpleJdbcTemplate leveraged new features of Java 5, whereas JdbcTemplate maintained compatibility with pre-Java 5 environments. But now all features of SimpleJdbcTemplate have been added to JdbcTemplate. It's not the only difference - SimpleJdbcTemplate supports named Java-5-based convenience wrapper for the classic Spring JdbcTemplate, taking advantage of varargs and autoboxing, and exposing only the most commonly required operations in order to simplify JdbcTemplate usage. Use the getJdbcOperations() method (or a straight JdbcTemplate) if you need to invoke less commonly used template methods.
