Connect database using Spring JdbcTemplate

This tutorial show you how to connect database using Spring JdbcTemplate. It is a important part of the Srping JDBC. It takes care of managing JDBC resources such as creating and closing of database connection. It also handles the exception and provides and returns the informative messages.

This class is implemented such as below.

2) Create the class FruitDao.java
This class has one property jdbcTemplate and three methods. The implementation of class such as below:

3) Create the spring configuration applicationContext.xml
To do with the database, you should configure spring context with three beans such as below:

Firstly, the bean DriverManagerDataSource is defined with the information about the database such as driver class name, connnection URL, username and password.

Secondly, the bean JdbcTemplate is defined to refer to the bean DriverManagerDataSource

Third, the bean FruitDao is defined to refer to the bean JdbcTemplate

You should implement the class main with name SpringJdbcTemplateSample to do the oprations using Jdbc Template. Firstly, you get the FruitDao bean from spring context then call the saveFruit() method, and you could uncomment to run two methods updateFruit() and deleteFruit() as well.

Finally, this tutorial show you the completely example how to connect database using Spring JdbcTemplate. If you have any opinion or questions about it, please leave a comment.
