Example of using PreparedStatement in Spring

We are assuming that you have created the following table inside the Oracle10g database.

Employee.java

This class contains 3 properties with constructors and setter and getters.

EmployeeDao.java

It contains one property jdbcTemplate and one method saveEmployeeByPreparedStatement. You must understand the concept of annonymous class to understand the code of the method.

applicationContext.xml

The DriverManagerDataSource is used to contain the information about the database such as driver class name, connnection URL, username and password.

There are a property named datasource in the JdbcTemplate class of DriverManagerDataSource type. So, we need to provide the reference of DriverManagerDataSource object in the JdbcTemplate class for the datasource property.

Here, we are using the JdbcTemplate object in the EmployeeDao class, so we are passing it by the setter method but you can use constructor also.

Test.java

This class gets the bean from the applicationContext.xml file and calls the saveEmployeeByPreparedStatement() method.
