Spring NamedParameterJdbcTemplate Example
Spring provides another way to insert data by named parameter. In such way, we use names instead of ?(question mark). So it is better to remember the data for the column.
Simple example of named parameter query
Method of NamedParameterJdbcTemplate class
In this example,we are going to call only the execute method of NamedParameterJdbcTemplate class. Syntax of the method is as follows:
Example of NamedParameterJdbcTemplate class
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 on property jdbcTemplate and one method save.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 NamedParameterJdbcTemplate class of DriverManagerDataSource type. So, we need to provide the reference of DriverManagerDataSource object in the NamedParameterJdbcTemplate class for the datasource property.
Here, we are using the NamedParameterJdbcTemplate object in the EmployeeDao class, so we are passing it by the constructor but you can use setter method also.SimpleTest.java
This class gets the bean from the applicationContext.xml file and calls the save method.
